Initial Installation
External Speaker
If you plan to use an external speaker, choose a speaker with an
impedance of 8 Ω. The external speaker jack accepts a 3.5 mm (1/8")
mono (2-conductor) plug.
After connecting the transceiver to the power supply, the supply voltage
can be displayed on LCD by pressing the
key together with the
key.
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.
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 50 Ω, 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.
External speaker adopt double port BTL, please care about the connection.
Do not use the speaker that requires grounding.
The range of displayed voltage is from 7V 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.
