8 BASIC OPERATION
8.1. Power On & Off
Usually the unit will be installed such that it powers off & on with the host mobile
radio or by a manual switch fitted by your installation mechanic. You can manually turn
off the Mobile cradle charger by pressing the front grey button for 3 seconds and the
blue LED will extinguish. You can do the same on the Mobile wireless remote speaker
microphone by pressing the grey button. The Mobile mic will sound a
de-escalating tone. To power On, do the same, releasing the button once the LED
lights. The Mobile mic will sound an escalating tone. The blue LED on both units will
flash momentarily and then go solid once they’re connected.
8.2. Volume Control
When you first activate the unit you should first ensure your mobile radio’s volume is
set to a comfortable listening level. You may then adjust the Mobile wireless remote
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 traffic and not inadvertently turn off the audio.
8.3. Transmitting/Receiving
Use like any two way radio speaker microphone i.e. press the large PTT button to talk
and release to listen. A short talk permit tone sequence will sound when activated.
Speak with a normal strong clear voice about 3-5cm (2”) from the microphone port. Do
not yell as this causes loss of clarity.
8.4. Out of Range Indication
MWRSM provides the user with audible feedback should the user move out of range
from their vehicle.
Note:- if you walk out of range the blue status LED will flash.
If you then push the PTT an alert tone will sound to let you know your call is not
getting though. Pressing the Emergency button when Out of Range will provide a
similar indication. Depending on your location, you may find you need to walk back
about 10 meters (yards) closer to your vehicle to reconnect Blue status light will then
glow solid.
8.5. Talk Permit tone
MWRSM provides talk permit tones so users know when to start speaking so that
words are not lost at the start of a transmission. If, the channel is busy, no channel
grant or you are out of range, the user will hear the MWRSM talk permit tones
