6. Turn off the radio and then disconnect the two SELF points on PCB to complete the model setting.
For example, if MS1 of TC-500-U (450.000~469.995MHz) is 0 (See the initial data table) and its
number refers to 7, then it is unnecessary to short out MS1 and MS2. To initialize its model and
channel data, you can operate as following:
(1) Short out the two SELF points on PCB;
(2) Turn on the radio and turn the Channel Selector Knob to the position 7;
(3) Press PTT key while holding down MONI key;
(4) After data reset, turn off the radio, disconnect the two SELF points and restart to use the radio.
Remarks: The old data (frequency, CTCSS/CDCSS, channel function settings) will be changed
once the model is set, and part of functions will also be changed. Therefore, do not make this
operation unless it' s very necessary, such as changing the EEPROM, etc.
