Preparing Your Radio for Use
English

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, refer to the “Troubleshooting”section.
A CH mismatch error upon turning on your radio,
means
that either the Control Head has been
connected to a legacy
transceiver, or vice versa.
The radio then performs a self check.
If your radio does not power up, contact your dealer.
To turn off the radio, press and hold the Power On/Off Button
anytime after the LED lights up.
