Basic Operation

Power on/off

Rotate the Power/Volume Switch to power on/off. Three

ascending tones will sound, indicating that the transceiver

has correctly powered on.

Adjusting Volume

When transceiver is power on, rotate it clockwise to

increase volume, anticlockwise to reduce volume.

Select Frequency

1, In VFO mode, press ▲ key to increase frequency,

press ▼ key to reduce volume. Or enter frequency

direct by keypad. (Note: If you can’t select your

desired frequency, please modify step through “F+4”.)

2, In MR/CH mode, press ▲ key to increase channel,

press ▼ key to reduce channel. Or enter channel

number directly by keypad.

Transmitting and receiving

To transmit, press and hold the PTT key of the

14

microphone and speak normally. Release the PTT key to

stop transmitting.

¤ Please use Low Power whenever possible. If the

distance between you and the other station is short,

low power (2 watts) should be adequate. Using low

power when possible will not only use less power

from your battery or power supply, but your

transmitter will also produce less heat, increasing the

life of your final amplifier.

¤ For best voice quality, hold the microphone about 2

IN (5 cm) away from your mouth and speak

normally.

¤ A red LED indicates that the transmitter is active.

Programmable key settings

The P1, P2 and Menu keys are user programmable. While

the short press of the Menu key can only be changed in

the programming software, the P1, P2 keys can be

programmed using Menus 14-17.

Each of these keys has two programmable functions,

accessed by a short press (press and release) or a long

press (Press and hold for 1.5 seconds). Each of these

functions is set in one of the programmable key menus.

Note: If you would like to change the hold time for Long

Press, you may do so using the programming software.

You may set any of the programmable keys to perform

the following functions:
