5.2 Adjusting the volume
To turn up the volume, turn the volume/power knob clock-wise. To turn the volume down, turn the
volume/power knob counter-clock-wise. Be careful not to turn it too far, as you may inadvertently turn your radio
off.
5.3 Making a call
NOTE: Press the [EXIT] key to switch the main channel to the other channel if there is 2 channels shown on the
display. In the off state, press and hold the [MENU] key to turn on the radio; it will switch between frequency
mode or channel mode.
Channel mode call: After selecting a channel, hold down the [PTT] key to initiate a call to the current channel.
Speak into the microphone with normal tone. Initiate a call, the red LED is on.
Frequency mode call: The off state, hold press [MENU] key to open the radio, switching to the frequency mode,
the frequency range allowed entering, press the [PTT] key, a call to the current channel. Speak into the
microphone with normal tone. Initiate a call, the red LED is on.

When receiving a call, the green LED is on.
NOTE: To ensure the best reception volume, keep the distance between the microphone and the mouth at the
time of transmission from 2.5 cm to 5 cm.
5.4 Channel selection
There are two modes of operation: Frequency (VFO) mode, and Channel or Memory (MR) mode.
For everyday use, Channel (MR) mode is going to be a whole lot more practical than Frequency (VFO) mode.
However, Frequency (VFO) mode is very handy for experimentation out in the field. Frequency (VFO) mode is also
used for programming channels into memory.
In Channel (MR) mode you can navigate up and down the channel by using the and keys.
Ultimately which mode you end up using will depend entirely on your use case.
5.5 Frequency (VFO) mode
In Frequency (VFO) mode you can navigate up and down the band by using the and keys. Each press will
increment or decrement your frequency according to the frequency step you've set your transceiver to.
You can also input frequencies directly on your numeric keypad with kilohertz accuracy.
The following example assumes the use of a 12.5 kHz frequency step.
Example. Entering the frequency 462.6125 MHz on display A
a. The off state, hold press [MENU] key to open the radio, switching to the frequency (VFO) mode.
b. Press [EXIT] until the icon appears next to the upper display. .
c. Enter [4][6][2][6][1][2][5] on the numeric keypad.
5.6 Channel (MR) mode
The use of Channel (MR) mode is dependent on actually having programmed in some channels to use.
Once you have channels programmed and ready, you can use the and keys to navigate between channels.
