Turning On the Radio
Press the Power On/Off 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 On/Off 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 either of these displays appear, if the
display goes blank, or if the unit appears to be locked
up, see Helpful Tips on page 99 for more information.
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 On/Off Button after the
LEDs light up.
