power from the batteries. As soon as a signal is heard
or the keys are pressed the TX670 will ‘wake up’
again. This Standby mode is automatic and by itself
can extend the battery life by many hours.
Using CTCSS
If you are expecting to receive signals on a busy
channel,youcanprogramthatchannelforCTCSS
operation and get the other person to call you using
the same CTCSS tone. Your radio will then remain in
Standby and ignore all other signals until your selected
CTCSS tone is received.
Scanning
The TX670 draws more power from the batteries when
scanning than when monitoring a single channel. This
is because it must ‘wake up’ more often to monitor
each channel for activity. You can lengthen the battery
lifebyavoidinganyunnecessaryscanning.Inaddition,
scanning increases the chance of finding a signal
thereby keeping the receiver ‘awake’ and the Squelch
open more often.
Low Transmit Power Settings
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 from 2 watts to 1
watt effectively doubling the talk time available.
