1) Access to Manual Adjust Mode:
Hold down PTT,SK1 and Power On key to power on the radio for 2 seconds or longer. In case of a longer period (longer
than 2 seconds), the orange LED (red LED plus green LED) glows, which indicates that the adjustment mode has been
entered. When the key is released, the radio will enter Item N of Tx group (N depends on the position where the channel
selector knob locates). Red LED glows in adjustment status of Tx group; green LED glows in adjustment status of Rx
group.
2) Switch of adjustment items in Tx group and Rx group:
This operation is done through the channel selector knob.
Red LED solidly glows when you are adjusting items in Tx group.
Green LED solidly glows when you are adjusting items in Rx group.
3) Switch of adjustment items in Tx group/Rx group:
This action is carried out by applying channel selector knob as follows:
Tx group: CH1-CH9, respectively stands for Tx low power, Tx high power, CDCSS balance, CDCSS deviation, CTCSS
deviation (low), CTCSS deviation (medium), CTCSS deviation (high), Tx low voltage threshold and Max. Tx audio
deviation.
Red LED solidly glows when you are adjusting items CH1-CH9.
Rx group: CH10-CH12, respectively stands for normal carrier squelch open, normal carrier squelch close and Rx low
voltage threshold.
Green LED solidly glows when you are adjusting items CH10-CH12.
With invalid CH13-CH16, no adjustment item can be found and LED goes out.
4) Wide/Narrow band switch for a certain adjustment item:
When adjusting a certain item, short press SK1 (orange LED flashes indicating valid press) to switch between
wide/narrow band. Then the first frequency of current bandwidth is the frequency to be adjusted by default.
5) Frequency switch under certain bandwidth and certain adjustment item
Short press (no longer than 1 second) PTT (green LED flashes indicating valid press) and automatically switch
adjustment frequencies under certain bandwidth and certain adjustment item.
6) Add/Subtract the adjustment value under certain bandwidth and certain adjustment item:
Rotate the volume control knob upwards, and the adjustment value will increase by 1 under certain bandwidth and certain
adjustment item; hold the knob up without release, and the adjustment value will keep increasing continuously in steps of
1. The adjustment value will keep unchanged once it reaches its maximum value.
Rotate the volume control knob upwards, and the adjustment value will decrease in steps of 1 under certain bandwidth
and certain adjustment item; hold the knob up without release, and the adjustment value will keep decreasing
continuously in steps of 1. The adjustment value will keep unchanged once it drops to its minimum value.
7) Measures on Special Items:
Tx group: Ch8 is the Tx low voltage threshold. These adjustment items are related to AD sampling. Rotate the volume
control knob up or down to activate AD sampling (including calculation) for one time after entering the above mentioned
adjustment options. Rotate the channel selector knob and save the current AD sampling value. If you do not rotate the
volume control knob, neither the AD sampling will be activated, nor the original adjustment value will be updated.
Rx group: CH10-CH12, respectively stands for normal carrier squelch open, normal carrier squelch close and Rx low
voltage threshold. These adjustment items are related to AD sampling. Rotate the volume control knob up or down to
activate AD sampling (including calculation) for one time after entering the above mentioned adjustment options. Rotate
the channel selector knob and save the current AD sampling value. If you do not rotate the volume control knob, neither
the AD sampling will be activated, nor the original adjustment value will be updated.
8) Description of Key-press:
Short press: key-press time is no longer than 1 second.
Long press: key-press time is longer than 1 second.
