• When receiving data, the set is put in the same state as the
intermittent reception state during normal wait.
• The channel is counted up each time the CH key is pressed. When
the channel reaches 29 ch (15 ch for CN1), then it returns to 1 ch.
• The JOG key may be used to change the channel.
• To clear all of the EEPROM, simultaneously press ERASE and
TALK keys.
• "Channel Setting", "SIGOUT Control" and "Power Control" can
be separately set.
