box at a point that has +13.8Volts continuously available(preferably the battery
side of the ignition switch) via the 2Amp fuse.
Radio turns OFF with the ignition switch
Connect the radio's negative(black) lead to the vehicle's chassis, or directly to the

Antenna information
For radio communications, the antenna is of critical importance,
to maximize your outputpower and receiver senstivity.
The transceiver accepts a 50 ohm antenna and less than 1:1.5 of voltage standing
wave ratio (VSWR).
High SWR values not ony may demage the transceiver
but also to TVI or BCI problems.
Antenna installation
1. Connect the antenna to the rear antenna socket using a PL259 coaxial connector.
2. To obtain maximum performance from the radio, select a high quality antenna
and mount it in a good location.
Do not press the PTT button before installing the antenna.
Optional accessory
If required you may install an external (8 ohm, max 5watt power) speaker fitted.
with a 3.5mm plug (not supplied)
There is a jack located on the rear of the radio and on the UHF 300 there is
an additional jack on the side of the remote head unit.
Operations
Press and hold the power/Channel selector for 2 seconds.
The default channel is set at 9CH, FM.
