BASIC OPERATIONS

Turning On the Power
Turn ( POWER ) / (VOLUME) knob clockwise to power on. Turn it counterclockwise to power off.

Adjusting Audio output level
Turn (POWER) / (VOLUME) knob clockwise to increase the audio level, counterclockwise to decrease.
The voice guidance or a channel beep can be used as sound level reference.

CAUTION: Never use earphones while adjusting the audio level. The max audio output is loud enough to hurt your eardrums. You may feel a static shock when wearing an earphone in a dry atmosphere but it’s not a defect of product but a cause of nature. It is the same static shock you feel typically when opening a door of a car in certain conditions.

Channels Selection
In stand-by state, turn the channel selector knob to select a desired channel.
In case the voice guidance is activated, it announces the channel number in voice.
If guidance is not in use, see a white line on the knob to identify the current channel.
When an empty channel is selected, a beep sounds until a programmed channel is selected.

Monitor Function
When the MONI key is pressed, the squelch unmutes regardless of the Radio Access Number(RAN)/ Subtone setting/Optional Signaling.

Receiving
When you receive a signal the LED indicator turns to green, and receiving voice is heard if signaling setting matches. In case the voice is not heard, use monitor function to temporary release signaling setting and squelch. (Analog channel)

Transmitting
Use monitor function if available or see the LED indicator is not lit green to make sure the channel is free. Press and hold [PTT] key then speak into microphone (MIC). Keep the distance of about 5cm between your lips and MIC, and speak at normal voice level. Release [PTT] key to receive. While transmitting the LED indicator turns red. Adjust the distance or voice level for the best transmitting audio. It takes a fraction of second until it actually sends out the voice signal so it is a good practice that you take a short moment before start speaking.

Mode (CH Group) Selection
By PC-preprogramming, 320 channels can be assigned in total which are divided into 20 groups with 16 channels in each group.
The Mode switch function is assigned to PF1 by default setting.
