The On/Off power switch on the SRM9022 is a red pushbutton located on the top right hand

side of the controller microphone.

To turn the radio on, press and hold the button down when the radio is off. The radio will turn

on after about one second and sound a beep.

The display will illuminate and show a ‘Welcome Message’ text as programmed by the Field

Programmer.

After about two seconds, the display will revert to the Channel Screen, at which time the

radio is ready for use.

Pressing and holding the power button when the radio is on will turn the radio off. A low tone

will sound as the radio turns off.

If the radio Power Down Timer is enabled, the mobile will automatically turn off after several

hours of inactivity (i.e. no keys pressed).

The radio will emit warning beeps for 10 seconds prior to automatically switching off.

Pressing any key will reset this timer.

5.2 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

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.

5.3 VOLUME ADJUSTMENT

The Volume Control adjusts the speech level at the radio speaker. The volume is adjusted by

a Volume Up and Down button on the top of the SRM9022 controller microphone

Note: The radio may be programmed so that the volume cannot be turned off completely.
