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.
