1. Turn OFF the units, Slide the battery-compartment catches inward
(in the direction of the arrows “ , ”).← → Battery indication
When you turn the power on, the battery condition is shown by the BATT
indication in the display section.
Be sure to check the expiration date printed on the new batteries before
using them.
NOTE
1.The indicated battery condition may not be correct if the batteries were not
new when installed. If you plan to use the units for a long period, it is
recommended that you replace the batteries with brand new ones.
2.Insufficient battery power can decrease the ability of transmitter and receiver.
Therefore, make sure your batteries start out with a full charge when using
this system, and always carry spare batteries.
Notes on battery
Batteries may leak or explode if mistreated.
Be sure to follow these instructions:
1.Make sure install the batteries with correct polarity.
2.Always replace two batteries together.
3.Do not use different types of batteries or old and new one together.
4.When not using the components for a long period of time, remove the
batteries to avoid leakage. If the batteries do leak, clean all leakage from
the battery compartment and the component.
Leakage left in the compartment and the component may cause poor battery
contact. If there seems to be poor battery contact, please consult our local
dealer.

battery holder in the original position.
To attach the shoe mount adapter
Before attaching the shoe mount adapter, attach the belt clip.
Reorienting the belt clip: The BY-WM6’s belt clip can easily be removed and
reattached to the body pack, so you can mount it upside down. To reorient the
belt clip, please follow the below steps:
1.Push outward on the belt clip at one of the hinges, so one side of the clip
pops out.
2.Push the belt clip out from the other hinge to completely remove the clip
from the body pack.
3.Realign the belt clip with the body pack, making sure the clip is facing the
desired direction.
4.Insert the two-way belt clip into the body pack, one hinge at a time.
To attach the shoe mount adapter
Connecting the Transmitter and the Receiver
To connect the transmitter and the receiver, follow these steps:
1.Make sure the supplied lavalier microphone connect to the transmitter’s
microphone input or plug a line-level source into the transmitter’s line input.
Note: If you are connecting the receiver to a sound system, mute the sound
system. Do not monitor with the headphones at the stage. Anytime you are
changing the channel, remove your headphones and mute connected sound
systems to avoid audible RF noise bursts.
2.Turn on the transmitter and the receiver.
3.Set the transmitter and the receiver to the same channel. If you are
experiencing interference or noise on one channel, try a different channel.
Noted:1) If you are using multiple BY-WM6 wireless systems, make sure
each system is set to a different channel, which can reduce the
chance of intermodulation.
2) If the transmitter and the receiver connect, the power indicator
stays blue. Otherwise, if the power indicator flash blue, that
means, the transmitter and the receiver is disconnected.
3) The results are stored in memory automatically. The stored
channel number will appear in the display section in next time if
you turn on the transmitter and the receiver.
4.With the headphone volume low, plug your headphones into the receiver and
gradually raise the level to a comfortable volume for monitoring the
transmission.
6. Once you have determined the transmission quality and level are good,
mount the transmitter and the receiver.
NOTE
1.When you are setting the transmission channel, the transmitter cannot
be used to transmit signals.
2.Do not remove the batteries while setting the transmission channel.
How to set up channel and VOL, please follow the below steps:

Important Notes
On usage and storage
.
Operating the BY-WM6 components near electrical equipment
(motors, transformers, or dimmers) may cause it to be affected
by electromagnetic induction.
Keep the BY-WM6 components as far as from such equipment as possible.
. The presence of the lighting equipment may produce electrical interference
over the entire frequency range. Position the BY-WM6 components so that
interference is minimized.
. To avoid degradation of the signal-to-noise ratio, DO NOT use the BY-WM6
components in noisy
Place or in locations subject to vibration, such as the following:
- Near electrical equipment, such as motors, transformers, or dimmers.
- Near air condition equipment or places subject to direct air flow from an air
conditioner.
- Near public address loudspeaker.
- Where adjacent equipment might knock against the receiver.
Keep the BY-WM6 components as far from such equipment as possible or use
buffering materials.
On cleaning
Clean the surface and the connectors of the BY-WM6 components with a dry,
soft cloth. Never use thinner, benzene, alcohol or any other chemicals, since
these may mar the finish.
Troubleshooting
If you have any problem using the BY-WM6 components, use the following
checklist.
If any problem persist, please consult our local dealer, or contact us directly.
Symptom Meanings Remedy
The units does
not turn on
The polarity orientation of the
batteries in the battery
compartment is incorrect.
The batteries are exhausted. Replace the batteries with
new ones.
The battery terminals in the
transmitter are dirty
Clean the + and - terminals
with cotton swab.
Insert the batteries with the
correct polarity orientation.
The batteries
become drained
quickly.
The batteries are exhausted. Replace the batteries with
new ones.
Manganese batteries are being
used.
Use alkaline batteries. The
battery life of a manganese
battery is less than half that
of an alkaline battery.
The BY-WM6 components is
being used under cold
conditions.
The batteries drain quickly
under cold conditions.
The channel
cannot be
changed
An attempt was made to
change the channel by
pressing the SET button only.
There is no
sound.
The channel setting on the
transmitter is different from
that on the receiver.
Use the same channel setting
on both the transmitter and
receiver.
The sound is
weak.
The attenuation level on the
transmitter is too high.
The input level of the
transmitter is low. Press the -
button on the transmitter in
attenuation level setting
mode to decrease the
attenuation level.
The line input is selected on the
transmitter.
Pull the cable out from LINE
IN.
There is
distortion in the
sound
There is
distortion in the
sound
The attenuation level on the
transmitter is too low.
The input level of the receiver
is extremely high. Press the +
button on the transmitter in
attenuation level setting mode
to increase the attenuation
level.
The transmitter and the
receiver are set to
different channels.
Set the transmitter to the
same channel.
Headphones with a mon-
aural min jack is used.
Use the headphones with a
stereo mini jack.
RF interference
.Try a different channel. Make sure
both units are on the same
channel.
.Try to position the antennas at a
45° angle in relation to each other.
There can be a lot of RF
interference outdoors.
.Try moving indoors, where there
is less RF interference.
.Keep the units' antennas at least
2'(0.6m) away from conductive
objects like metal and water.
.Overhead telephone lines,
fluorescent lighting, and metal
fences can all cause interference.
.Turn off all nearby computers
and mobile phones.
The audio is
noisy or
distorted. This
can include drop
outs, white
noise, bursts,
pops and clicks.
RF signal is weak.
Make sure there is an unobstructed
line of sight between the
transmitter's and the receiver's
antennas.
Keep in mind that your body,
clothes, and onstage sets are
possible obstructions.
Make sure the receiver and
the transmitter are within
328'(100m) range.
If there are obstructions, you
may need to move closer.
The input level on the
camera, recorder, or
mixer is too high.
Turn down the audio input level on
your camera or recording device.
Lower the audio output level on
the receiver.
Turn down the gain on your mixer.
If there is no adjustment on the
device, and the level is still high,
adjust the microphone level on the
transmitter. Keep this level as high
as possible without distortion.
