(3) Press [MONI],then press [PTT], to set the channel, channel data and initial data.
(4) Turn off the power, disconnect SELF on PCB to end mode settings.
(5) Remarks:

The old data(frequency, CTCSS/DQT, channel function) will be deleted once set the new
mode by pressing MONI AND PTT , part of the function also would be changed. Therefore, do
not set this operation unless change the EEPROM, etc.
