Conserving Battery Power
The TX630 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 TX630 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 TX630 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
TX630 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 TX630 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. You can squeeze
that extra bit of life from the battery pack
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
Watts to 1 Watt effectively doubling the talk
time available.
generaL oPeration
Power on/off
Rotate the Volume control clockwise past
the ‘click’ to turn the radio on. Rotate the
control counter-clockwise past the click to
turn the radio off again.
adjusting the Volume
With the unit powered on, rotate the
Volume control clockwise to increase the
volume and counter-clockwise to decrease
the volume.
Display Lighting
The LCD backlighting activates
automatically whenever a key is pressed
and turns off automatically after about
5 seconds.
receiving signals
While the TX630 is not receiving signals, it
will remain in the Standby mode to conserve
battery power.
When a signal is received, the LED indicator
on the upper edge of the radio will light
Green and the icon will appear on the
display. Adjust the volume control for a
comfortable listening level.
If the incoming signal is encoded with
a CTCSS tone that matches the one set
in your radio, the LED indicator will light
Orange and you will be able to hear the
signal in the speaker.
If the LED indicator lights Green and the
icon appears but you cannot hear the signal,
it is likely that your radio has CTCSS enabled
and the incoming signal is not using your
selected CTCSS tone (see Mode Settings for
more details on CTCSS settings).
If no further signals are received, the unit
will return to standby mode.
