the time taken to discharge the battery pack will depend on how you use the radio.
the battery pack supplied is powerful enough for up to two days of use under average
conditions using low power.
battery loW alert
when the battery icon blinks on the radio’s display, the battery level is low and the
battery pack should be recharged.
conserVing battery PoWer
the radio has built-in power saving features to help you get the maximum amount of
time between charges from your li-ion battery pack. if you need to operate your radio
in a situation where you require maximum battery life (e.g. a remote site where there
is no convenient recharging facility nearby) the following hints can greatly reduce the
amount of power drawn from the battery pack.
stanDby moDe
the radio will automatically enter the ‘standby’ mode when it is inactive (i.e. not
transmitting or receiving signals).
while in standby mode it will still check for incoming signals but it will draw
considerably less power from the battery pack. As soon as a signal is heard or the
keys are pressed the radio will ‘wake up’ again. this standby mode is automatic and
by itself can extend the battery life by many hours.
using 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.
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 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 to 0.5
watts which increases the talk time available.
