1. QUICK SET UP AND OPERATION
Synching Up the Transmitter and Receiver
The synch operation only needs to be performed the first time a system is used, or a new Transmitter is used
with a Receiver previousl y synched to another Transmitter. Do not perform the synch operation multiple
times; it only needs to be done one time when a n ew Transmitter is used with a new Receiver.
1) Turn the Transmitter power switch to ON and place the Transmitter in the recharge cradle of the
Receiver. The Transmitter goes in the Receiver with the belt clip facing out.
2) The recharge LED will light (Green if fully charged, Red if charging). Leave the Transmitter in the cradle
for 4 hours for a full charge.
3) Press the REC button on the transmitter and hold until the In-Use LED on the Transmitter and Receiver
start to flash, then release the button.
4) After a few seconds the light will stop flashing, and a beep will sound (If the beep is enabled).
5) The transmitter and Receiver are now synched and will continue to be until another transmitter is linked
to that Receiver.
Normal Operation
1) With the transmitter synched up, remove it from the cradle, plug in the lapel microphone (if used)
and place the transmitter on your belt.
2) When you remove Transmitter from the cradle, The TR and Receiver’s In-USE LED wi ll li gh t a
constant
Green and you will hear short beep. To start the recording, press the REC button and the In-Use
LED will blink in green.
3) To end recording, press the REC button and the In-Use LED will light a constant green.
4) At the end of your shift turn the transmitter off and replace it in the charging cradle.
Out of Range
1) The transm itter will alert you with Audible warning beeps (two tone) and the In-Use LED wil l blink in
red.
2) Move closer to the Receiver and the link will be re-established once you return to normal
range. The In-Use LED will light constant green when link is back to normal operation.
3) If the link is not re-established within 30 seconds, the transmitter and receiver will return to standby
mode.
4) If you went out of range in Standby mode, or the unit reverted to standby mode, re-enter normal range
and press the In-Use button. Operation will return to normal.
5) If you will be out of range for a long period of time, turn the Receiver off.
Low Battery Warning
1) If the transmitter Low BATT indicator (red) starts flashing or you hear warning beeps, return the
transmitter to its cradle on the receiver to fully charge the transmitter.
2) The Charge LED indicator will light constant green when the unit is fully charged.
EMG Button (if wired the white cable to Alarm in of the BRX for use in your vehicle)
1) The EMG Button (Trigger 2) can be programmed to do many things but may not be connected in your
vehicle. Check with your technical department to understand what this button will control before you use
it.
2) In Trigger mode: Press the EMG button on the transmitter, a beep will sound and the relay will be
triggered at the receiver.
3) In Standby mode: Press the EMG button on the transmitter, a beep will sound and the relay will be
triggered at the receiver.
Disabling the Beep Sound On the Transmitter
1) All of the audible beep signals on the transmitter can be disabled by setting the BEEP switch to the
1) The REC Button (Trigger 2) can be programmed to do many things but may not be connected in your
vehicle. Check with your technical department to understand what this button will control before you use
it.
2) In Trigger mode: Press the REC button on the transmitter, a beep will sound and the relay will be
triggered at the receiver.
3) In Standby mode: Press the REC button on the transmitter, a beep will sound, the green In-Use indicator
will blink and the relay will be triggered at the receiver.

3. GUIDELINES AND RECOMMENDATIONS FOR BEST PERFORMANCE
Compatibility
The transmitter and receiver must synchronize to work together (see Synch process on page 3). The synch
operation only needs to be performed the first time a system is used, or when a new Receiver is used with a
Receiver previously synched to another Receiver. Do not synch multiple times, just once until a new
Receiver is used. Any Receiver can be synchronized with any Transmitter.
Using Multiple Wireless Systems
This system has 95 possible “channels” that are really different frequency hopping schemes. Each
synchronized Receiver and transm itter will automatically find a clear channel so up to 40 systems can work
together in one location depending on other interference problems
Potential Sources of Interference
There are many potential sources of interference for your wireless system. Any electronic product that
contains digital circuitry including digital signal processors (reverb/multi-effects units), electronic keyboards,
digital lighting controllers, CD and DVD players, and computers, all emit RF energy that can adversely affect
the performance of your wireless system. It is always best to place the receiver as far away as possible from
these devices to minimize potential problems.
This system operates in the 2.4MHz ISM band and other devices in that band may interfere. The spread
spectrum technique used in this system is very robust and should operate even in the presence of other
2.4MHz devices such as walkie-talkies, LANs, cordless phones, etc. in the area.
Battery Recommendations
The Lithium-Ion batter y built into t his transmitter will work at full c apacity for over 500 charge cycles . If you
notice lower than usual battery life over time, it may be time to replace the cell
Warnings
Do not use this product in or near water, i.e. near a bathtub, sink, or swimming pool.
Do not use this product in the vicinity of a gas leak or to report a gas leak.
