GME TX677 - General Operation

TX677 Instruction Manual
18
USE CTCSS/DCS
If you are expecting to receive signals on a busy channel, you can program that
channel for CTCSS/ DCS operation and get the other person to call you using the
same CTCSS/DCS tone. Your radio will then remain in Standby and ignore all other
signals until your selected CTCSS/DCS tone is received.
AVOID SCANNING
The radio draws more power from the battery pack when scanning than when
monitoring a single channel. This is because it must ‘wake up’ more often to
monitor each channel for activity. In addition, scanning increases the chance of
nding a signal thereby keeping the receiver ‘awake’ and the Squelch open more
often.
USE LOW TRANSMIT POWER
The transmitter has both high and low power settings. If you are only operating
over short distances, are in a reasonably high location or are close to a local
repeater, try using the Low transmitter power setting. This reduces the transmitter
power to 0.5 watts which increases the talk time available.
