Initial Installation
External Speaker
If you plan to use the optional external speaker/s, There are 2
options. For a single speaker, plug into the 3.5mm SP Jack on the
rear of the radio to hear both bands through one speaker. To use dual
speakers, use the stereo plug it into the 3.5mm ST Jack on the rear
of the radio to split the left and right bands between the 2 speakers.
After connecting the transceiver to the power supply, long press the
key, enter Menu 12: Sub Band Display menu, and select DC-IN, then it
will appear current power supply voltage on the right side of Screen.
The display immediately changes as the voltage supply changes, It also
displays voltage during transmission.
Before operating, install an efficient, well-tuned antenna. The success
of your installation will depend on the type of antenna and its correct
installation.
Use a 50Ω impedance antenna and low-loss coaxial feed-line that
has a characteristic impedance of 50Ω, to match the transceiver input
impedance. Coupling the antenna to the transceiver via feed-lines having
an impedance other than 50Ω reduces the efficiency of the antenna
system and can cause interference to nearby televisions, radio receivers
and other electronic equipment.
The range of displayed voltage is from 8V to16V DC. Because the
displayed value is estimated, please use a voltmeter when a more
precise reading is desired.

Important
Transmitting without first connecting an antenna or other matched
load may damage the transceiver. Always connect the antenna to the
transceiver before transmitting.
All fixed stations should be equipped with a lightning arrester to reduce
the risk of fire, electric shock, and transceiver damage.
External speaker
Microphone
For voice communications, connect a provided microphone into the
socket on the front of the main unit. Turn the ring firmly on the plug
until it locks. Attach the supplied microphone hanger in an appropriate
location using the screws included in the screw set.
