SET-UP & OPERATION
Once the Flexmike is charged, follow these steps for use.
1. Remove the Flexmike from the charger and put it on by connecting the
magnetic clasps behind your neck. Adjust the lanyard so that the top of the
Flexmike aligns with the collarbone.
2. The Flexmike will automatically power on and mute when it is removed from
the charger.
3. The microphone volume on the Flexmike is set at the factory to the midpoint.
It is adjusted by the up/ down buttons on the side of the mic.
4. While speaking in a normal voice, fine tune the microphone volume. Proper
volume level should be as follows:
• Your voice should be clearly heard by another person on the other side of
the room.
• You should barely be able to hear your own voice.
• There should not be any audio “feedback” or squealing outside of 2-3 feet
(if there is, turn the volume down slightly).
REMEMBER: This equipment supplements the user’s voice so they are able
to speak in a conversational tone. Having the volume set too high will result in
feedback and listener fatigue.
• Once initial volume level is set, walk around the room and listen for overall
audio quality.
• If further fine tuning is required, you may need to adjust the Tone Control on the
front of the 975.
• If the Flexmike is out of range, it will automatically shut o aer 30 minutes of
trying to reconnect. Once you are back in the classroom, or in range, simply
press and hold the power button on the Flexmike to power it up and resume
normal operation.

Using the Life Safety Functions
The 975 connects and responds to several important third-party life safety solutions.
2. PageFirst
MUTES CLASSROOM AUDIO SYSTEM
When the PageFirst sensor clip is
connected to an external paging
source, all audio signal is muted to
ensure paging is heard clearly.
See page 17 for installation details
1. Input Priority
MUTES CLASSROOM AUDIO SYSTEM
When an audio source is connected to
the Input Priority jack, an audio signal
from that source will automatically
mute all other audio inputs to allow it
to be heard without interference. The
975 is shipped with a removable plug
inserted into the Input Priority jack to
ensure that the connection to an audio
source is intentional.
3. Relay Input
MUTES CLASSROOM AUDIO SYSTEM
When the 975 is connected to a fire
alarm, audio signals going through the
unit are muted when the fire alarm
is activated to minimize distractions
from the sound of the alarm.

4. Alert Notification
INITIATES ALERT WITH FLEXMIKE
If your building is equipped with an alert
notification system, simultaneously
holding down the volume up and
down buttons for three seconds on the
Flexmike activates the contact closure
function on the 975. External systems
sense this contact closure to perform
a prescribed action, notifying the
appropriate parties of a classroom alert.
See page 17 for details

SET-UP & OPERATION
Installing PageFirst Sensor
(optional)
This 975 can interface with an independent classroom paging system.
When a page is broadcast, all audio from the system is muted, ensuring
important school-wide messages are not missed. Please note that PageFirst
is not compatible with telephone or IP-based paging systems.
How it works:
1. PageFirst sensor clip is hung around a lead wire attached to the
classroom paging speaker.
2. The clip is hard-wired to the amplifier.
3. As a page is broadcast, the sensor clip detects the audio signal through
induction and immediately mutes the amplifier.
4. When the page is over, the audio from the amplifier returns to normal
volume level.
USING ALERT NOTIFICATION
If your building is equipped with an alert notification system, you can use
the Flexmike to send an alert. This activates the contact closure function on
the 975, which external systems use to perform a prescribed action, such as
notifying the appropriate parties of a classroom alert.
How it works:
1. To send an alert, simultaneously hold down the volume up and volume
down buttons on the Flexmike for three seconds.

MAINTENANCE & TROUBLESHOOTING
PROBLEM: Low battery indication: Most problems are directly related to low
battery power. Please run through the “Battery Check” items first. For remaining
troubleshooting, use known good, fully-charged batteries.
SOLUTION: Battery Check
• Confirm batteries are charged each night. A solid red light on the battery
status light indicates a low battery.
• Confirm proper batteries are used: Flexmike and Sharemike require the
Lightspeed #L3.7V rechargeable battery pack.
• Make sure the microphones obtain a full charge. A full charge takes 5-6 hours.
• When charging the transmitter, the red charging light is solid. The green light
will be solid when a full charge is reached.
PROBLEM: Microphone doesn’t indicate a “Ready” signal (solid white light)
SOLUTION: Follow these steps to ensure the system is ready to use.
• Ensure the power button on the microphone is turned on. Once turned on,
the white light should begin blinking.
• Power the microphone o, then on again aer a few seconds. Wait for up to
30 seconds for the white light to turn solid, indicating READY for operation.
PROBLEM: Low volume or feedback
SOLUTION: Follow these steps to eliminate low volume or feedback:
• If the volume is too high, feedback will occur. Adjust accordingly.
• Adjust the volume level on the Flexmike.
PROBLEM: No sound from speaker and wireless components
SOLUTION: Follow these steps to produce sound from 975:
• Confirm that the white POWER light located on the front panel of the 975 is on.
• Confirm the microphone is powered on and linked to the 975. The Mic 1 status light
will be white on the 975 indicating the microphone is linked.
• Confirm that the microphone is turned on. There will be a solid blue light on the top
of microphone to indicate it is powered on and ready.
• Confirm that microphone is not muted. A solid white light on the top of microphone
will indicate it is muted.
• Check speaker connections on the 975. Make sure the cables are properly
connected (see page 8 of this manual or the Installation Guide for more
information).
• If an Activate Station or Media Connector is paired with the 975, make sure that the
volume level of the Activate or the Media Connector is not turned down all the way.
• Slowly turn up the volume level while talking into the microphone.
PROBLEM: Soware update is needed
SOLUTION: Go to https://app.tara.lightspeed-tek.com/ and follow the steps.

MAINTENANCE & TROUBLESHOOTING
• Speak in a natural voice. A normal conversational speech level will provide
an adequate signal. It is not necessary to increase the intensity of your voice—
the audio system provides adequate amplification (approximately 5–10 dB)
above ambient room noises.
• Avoid wearing jewelry that may rub or bump against the microphone.
• Mute the Flexmike during private conversations with a student, parent, or
other classroom visitor. You can tell the mic is muted when the light turns
white.
• Recharge microphones each night. When recharged nightly, operating time
(actual usage) for the microphones will last through a typical school day.
