Basic Operation
Power On & Off
Usually the unit will be installed such that it powers off & on in syn-
chronization with the host mobile radio or by a manual switch t-
ted by your installation mechanic. You can manually turn off the  
mobile charger by pressing the front orange button for 3 seconds 
and the blue LED will extinguish. You can do the same on the 
Wireless Speaker Microphone by pressing the lower grey button. 
The speaker mic will sound a de-escalating tone. To power On, 
do the same, releasing the button once the LED lights. The speak-
er mic will sound an escalating tone. The blue LED on both units 
will ash momentarily and then go solid once they’re connected.
Volume Control
When you rst activate the unit you should rst ensure your mobile 
radio’s volume is set to a comfortable listening level. You may 
then adjust the Wireless Speaker Microphone volume by pressing 
the right top button to increase or the left to decrease. There are 
5 listening levels. The minimum level is not zero but is designed so 
you can still quietly hear radio trafc.
Transmitting/Receiving
Use like any two way radio i.e. press the large grey PTT button to 
talk and release to listen. Speak with a normal voice about 3-5cm 
(2”) from the microphone port. Note: if you walk out of range the 
blue status LED will ash. If you then push the PTT an alert tone will 
sound to let you know your call is not getting though. Depending 
on your location, you may nd you need to walk back about 10 
meters (yards) to re-connect. Blue status light will glow solid. The 
unit features a 3.5mm earpiece jack allowing use of a huge vari-
ety of personalized earpieces. Plugging in an earpiece disables 
the internal loudspeaker for added privacy.
Emergency 
If enabled, the emergency button can be used to trigger and 
reset the emergency function in your suitably equipped mobile 
radio. The time you hold the button is the time your mobile radio 
sees the emergency command. So if your mobile radio requires 
you to hold the radios front panel emergency button for 2 sec-
onds, then you should hold the Wireless Speaker Microphone 
emergency button for 2 seconds.
