 Turning on/off the Radio 
PREPARING YOUR RADIO FOR USE 
Press the Power Button briefly to power on the radio. 
 
After a short time, the red, yellow and green LEDs light up. 
The display then shows Zone and channel text, and menu 
items display on the screen. 
 
The backlight will turn on to the last selected dim level. 
 
Note: 
Pressing the Power Button before the LED lights up will 
be ignored. 
 
If FAIL ##/## appears in the display, the radio will not 
function until the condition has been corrected. 
 
If ERROR ##/## appears, some non-critical data has been 
changed.  
 
If the power-up test is unsuccessful, you see Error XX/YY 
(XX/YY is an alphanumeric code). 
 
Turn off the radio, check the battery, and turn the radio 
back on. If the radio fails the power-up test again, record 
the Error XX/YY code and contact your dealer. 
If CH MISMATCH appears, means that either the Control 
Head has been connected to an incompatible transceiver, 
or vice versa. 
 
If your radio does not power up, contact your dealer. 
 
To turn off the radio, press the Power Button after the LEDs 
light up.
