Power supply voltage Display

After connecting the transceiver to the power supply, the supply voltage
can be displayed on LCD by pressing the
key.
FUNC
The display immediately changes as the voltage supply changes, It also
displays voltage during transmission.
The transceiver will return to its normal operation when the power is
turned ON/OFF or repeat above operation.
The range of displayed voltage is from 7V to16V DC. Because the
displayed value is estimated, please use a voltmeter when a more
Important
precise reading is desired.

Antenna Connection

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.
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
If you plan to use an external speaker, choose a speaker with an
impedance of 8Ω. The external speaker jack accepts a 3.5mm (1/8")
mono (2-conductor) plug.
External speaker adopt double port BTL, please care about the connection.
Do not use the speaker that requires grounding.
