Laser Information
The Unitech MS842P is certified in the U.S. to conform to the requirements of DHHS/CDRH
21CFR Subchapter J and to the requirements of IEC 825-1. Class II and Class 2 products are
not considered to be hazardous. The MS842P contains internally a Visible Laser Diode (VLD)
whose emissions do not exceed the maximum limits as set forth in the above regulations. The
scanner is designed so that there is no human access to harmful laser light during normal
operation, user maintenance or prescribed service operations.
The laser safety warning label required by the DHHS/IEC for the MS842P’s optional laser
scanner module is located on the memory compartment cover, on the back of the unit.
CAUTION! Use of controls or adjustments or performance of procedures other than those
specified herein may result in hazardous laser light. Use of optical instruments with
the scanner, including binoculars, microscopes, and magnifying glasses, with will
increase eye damage. This does not include eyeglasses worn by the user.

Battery Notices
The MS842P is equipped with a Lithium-Ion battery. The battery will discharge after an
extended period of no use.
When the battery is discharged, recharge the unit for some 4.5 hours in order to fully charge
the battery.
Note: To guarantee optimal performance, it is advised that rechargeable batteries be replaced
every year, or when 500 charge/discharge cycles are achieved. It is normal that the
battery balloons or expands beyond one year or the maximum of 500 cycles. Although it
does not cause harm, it cannot be used again and must be disposed of according to the
location's safe battery disposal procedures.
If the performance, of a Lithium-Ion battery, decrease is greater than 20% in, the battery
is at the end of its life cycle. Do not continue to use, and ensure the battery is disposed
of properly.
The length of time that a battery lasts depends on the battery type and how the device is used.
Conserve the battery life by doing the following:
Avoid frequent full discharges because this places additional strain on the battery. Several
partial discharges with frequent recharges are better than a full discharge. Recharging a
partially charged lithium-Ion battery does not cause harm because there is no memory
effect.
Keep the lithium-Ion battery cool. Avoid a hot car. For prolonged storage, keep the battery
at a 40% charge level.
Do not leave the lithium-Ion battery discharged and unused for an extended period
because the battery will wear out and the longevity of the battery will be at least half of the
one with frequent recharges.
Battery charge notice
It is important to consider the environment temperature when the Lithium-Ion battery pack is
charged. Charging is most efficient at normal room temperature or in a slightly cooler
environment. It is essential that batteries are charged within the stated range of 0°C to 40°C.
Charging batteries outside of the specified range could damage the batteries and shorten their
charging life cycle.
CAUTION! Do not charge batteries at a temperature lower than 0°C. This will increase the
internal resistance to cause heat and make the batteries unstable and unsafe.
Please use a battery temperature detecting device for a charger to ensure a safe
charging temperature range.
Storage and safety notice
Although the charged Lithium-Ion battery may be left unused for several months, their capacity
may be depleted due to build up of internal resistance. If this happens they will require
recharging prior to use. Lithium-Ion battery may be stored at temperatures between -30°C to
70°C, however they may deplete more rapidly at higher temperatures. It is recommended to
store batteries at room temperature.

v
Warranty
The following items covered under the Unitech Limited Warranty are free from defects during
normal use:
MS842P – 1-year limited warranty.
Lithium-Ion battery – 6-month limited warranty.
Warranty becomes void if equipment is modified, improperly installed or used, damaged by
accident or neglect, or if any parts are improperly installed or replaced by the user.
Use only the adapter supplied. Using the wrong adapter may damage the unit and will void the
warranty.

Battery Charging and Connection
Connecting a USB Interface, Dongle Mode
Dongle Mode (with SCM support)
In order to establish a proper connection between your computer and a scanner
through a dongle, we suggest that you follow these step-by-step instructions:
1. Turn on your computer or laptop PC.
2. Insert a dongle into a USB port of the
computer or laptop PC.
3. Scan the MAC address on the label by
using the MS842P scanner.
4. When being successfully connected to the dongle, the scanner will beep
shortly one time with a high tone.
SPP Setting
To do the SPP setting, scan the SPP
setting bar code.
SPP
HID Setting
To make the scanner return to the HID
mode, scan the HID barcode.

4. Connect the cradle to the USB port of your computer with a USB cable for
transferring data to your computer by using the MS842P scanner.
5. Insert a USB dongle into the USB port of the cradle.
6. Scan the MAC address on the label by using the MS842P scanner.
7. When being successfully connected to the dongle, the scanner will beep shortly
one time with a high tone.
When being not used, the scanner can be also set on the cradle for battery
charging.

Memory Buffer Setting
The collected data can be sent back to a host computer one by one via the WPAN
connection as the scanner is set to the Batch Mode, or can be stored in the flash
memory of the scanner being set to the Inventory Mode.
By default, the Batch Mode is enabled for use when the scanner is out of range.
Upon reading a barcode successfully within range, the scanner responds with one
short beep (high tone) and its LED indicator becomes solid green and goes off
quickly. However, the host computer may not receive the data immediately if
getting out of range. With the 2MB transmit buffer, the scanner can ignore the
transmission status and keep on reading barcodes until the buffer is full.
When the Batch Mode is enabled and the scanner is out of range, the scanner will
respond with two short beeps, high-low tone, upon reading a barcode successfully.
When the memory buffer is full, the scanner will respond with one long beep (low
tone) and its LED indicator will become solid red and go off quickly. You are
advised to get back to range.
MS842 features 2 memory mode settings: Batch Mode and Inventory Mode
Note: The 2MB of memory buffer in the scanner can hold as approximately many
as 1290555 scans based on EAN-13 barcodes. Data will be cleared out once
the scanner is not powered!
Batch Mode
Batch Mode is the default setting. In the Batch Mode, once you scan a barcode by
using a scanner wirelessly connecting to the cradle (Cradle Mode) or a host PC
(Cradle-less Mode) in a specified range, the scanner sends out the data. When the
scanner is out of range of the cradle or the host and keeps trying to re-connect, the
scanner will keep the data in its memory buffer until the buffer is full; when the
scanner is again in range of scanner will sent out the the cradle or the host, the
data that it has in the memory buffer. When the buffer is full and the scanner is out
of range, the scanner will respond with one long beep (low tone) and its LED
indicator will become solid red and go off quickly. You are advised to get back to
range.
Batch Mode
If you do not output the barcode data, the barcode data is always kept in the
memory buffer. When being outputted, the 1D data is erased from the memory
buffer. However, when being outputted, the 2D data is still kept in the memory
buffer, and thus if you want to erase the 2D data from the memory buffer, scan the
following barcodes in the order.
Enter Batch Buffer Erase Erase
When the scanner is out of batch mode, the data will be temporarily stored in the
RAM, which has 4K storage capacities; however, in the inventory mode, the data
will be stored in the flash, which has 2MB storage capacities.
8

Note:
If you tend to operate off line for long time, please set the scanner to the inventory
mode. Otherwise, the data stored in the RAM will be lost when the scanner runs out
of battery power.
Inventory Mode
Inventory Mode is the mode I n which the scanner keeps the scanned data in its
memory buffer but not send out the data on the host automatically; you should scan
Read Buffer barcode to order the scanner sent out the memorized data to the Host.
To set the scanner to the Inventory Mode, scan the following barcodes in the order:
Inventory Mode
Bear in mind the fact that the scanner operating in the inventory mode does not
send out the scanned data automatically but keeps the data in its memory buffer. If
you want to make the scanner output the data it scanned before, please scan the
Read Buffer barcode as shown below:
Read Buffer
Note: After scanning the Read Buffer barcode, the data is sent from the memory
buffer.
If you do not output the barcode data, the barcode data is always kept in the
memory buffer. When being outputted, the 1D data is erased from the memory
buffer. However, when being outputted, the 2D data is still kept in the memory
buffer, and thus if you want to erase the 2D data from the memory buffer, scan the
following barcodes in the order.
Enter Inventory Buffer Erase Erase
If you are out of range of the cradle or the host PC when reading out the scanned
data, the scanner will keep the data in its memory buffer until the buffer is full; only
when the scanner is within the specified range of the cradle or the host, and you
scan the Read Buffer barcode the data will be sent.
When the buffer is disabled and the scanner is out of range, the scanner will
respond with one long beep (low tone) and its LED indicator will become solid red
and go off quickly. You are advised to get back to range.
Buffer Mode Disable
To disable the buffer mode, scan the bar code below.

Output Data Editing
Transmit Code ID Character
A Code ID character identifies the code type of a scanned bar code. This is useful
when decoding more than one code type. In addition to any single character prefix
already selected, the Code ID character is inserted between the prefix and the
decoded symbol.
Select no Code ID character, a Symbol Code ID character, or an AIM Code ID
character.
Note: If you enable Symbol Code ID Character or AIM Code ID Character, and enable Transmit “No
Read” Messag, the digital scanner appends the code ID for Code 39 to the NR message.
Prefix/Suffix Values
You can append a prefix and/or one or two suffixes to scan data for use in data
editing. To set a value for a prefix or suffix, scan a four-digit number (i.e., four bar
codes) that corresponds to that value.
When using host commands to set the prefix or suffix, set the key category
parameter to 1, then set the 3-digit decimal value.
To correct an error or change a selection, scan Cancel.
Note: To use Prefix/Suffix values, first set the Scan Data Transmission Format as shown below.

Scan Data Transmission Format
To change the scan data format, scan one of the following eight bar codes
corresponding to the desired format.
Note: If using this parameter, do not use ADF rules to set the prefix/suffix.
To set values for the prefix and/or suffix, see Prefix/Suffix Values.

FN1 Substitution Values
The wedge and USB HID keyboard hosts support a FN1 Substitution feature.
Enabling this substitutes any FN1 character (0x1b) in an EAN128 bar code with a
value. This value defaults to 7013 (Enter key).
When using host commands to set the FN1 substitution value, set the key category
parameter to 1, and then set the 3-digit keystroke value. See the ASCII character
set table for the current host interface for the desired value.
To select a FN1 substitution value via bar code menus:
1. Scan the bar code below.
2. Locate the keystroke desired for FN1 substitution in the ASCII character set
table in the appropriate host interface chapter. Enter the 4-digit ASCII value by
scanning each digit.
To correct an error or change the selection, scan Cancel.

Auto Aim
Low Power Mode
This parameter determines whether or not the digital scanner enters low power
mode after a decode attempt. If disabled, power remains on after each decode
attempt.
Time Delay to Low Power Mode
This parameter sets the time the decoder remains active after decoding. After a
scan session, the decoder waits this amount of time before entering Low Power
Mode.
Note: This parameter only applies when Power Mode is set to Low.

Video Mode
In this mode the decoder behaves as a video camera as long as the trigger is
active. Upon trigger release, the decoder returns to Decode Mode. Scan the Video
Mode bar code to temporarily enter Video Capture Mode.
Image File Format Selector
Select an image format appropriate for the system (BMP, TIFF, or JPEG). The
decoder stores captured images in the selected format.

Video View Finder
Select Enable Video View Finder to project the video view finder while in Image
Mode, or Disable Video View Finder to turn the video view finder off.
Mirrored Image
Enable this to scan images in reverse, or mirrored, as if seen through a mirror. This
mode is useful in applications requiring scanning through a mirror and using
symbologies that do not decode in reverse.
Enabling this mode when using snapshot, video, or video viewfinder mode
transmits images as mirrored images.
Beep After Good Decode
Scan a bar code below to select whether or not the decoder issues a beep signal
after a good decode. If selecting Do Not Beep After Good Decode, beeper signals
still occur during parameter menu scanning and to indicate error conditions.
