6 COMMON FUNCTIONS AND FACILITIES
6.1. SWITCH ON/SWITCH OFF
The On/Off power switch on the SRM9022 is a red push-button located on the top
right-hand side of the radio controller microphone.
To turn the mobile on, press and hold the button down until a beep is heard. The radio
will turn on after about one second.
The display will illuminate and show a “Welcome Message” as programmed by the FPP.
After approximately 2 secs, the display will revert to the Channel Screen, at which time
the radio is ready for use.
Pressing and holding the power button while the radio is on will turn the radio off,
when a low beep is heard, release the button.
If the radio Power Down Timer is enabled, the radio will automatically turn off after a
predefined duration of inactivity as set by the FPP (i.e. no keys pressed). The radio will
emit warning beeps for 10 seconds prior to switching off. Pressing any key will reset
this timer.
6.2. DEFAULT SCREEN TRUNKED MODE
After power up, the radio will show the currently selected Zone and Channel. If the
selected channel is a trunking channel, the radio will scan until it finds the trunked
system. This will typically take a few seconds if the trunked network is available.
Trunked mode is indicated by the T icon. The rotating arrow indicates that the radio is
scanning for a trunked network. When the arrow is not shown, the radio is registered
with the trunked network and ready to make or receive a call.
