PAGE 6 INSTRUCTION MANUAL TX670TP
Charging the Batteries
Your TX670s are supplied with an AC adapter and semi-quick
charger that will recharge a fully discharged 1500 mAh battery
pack to full capacity in around 6-7 hours. The semi-quick charger is
capable of charging 2 radios at once.
1. Plug the AC adapter into a standard 240 volt AC outlet.
2. Plug the lead from the AC adapter into the charging cradle.
3. Place the TX670s into the cradle. The associated LED will light
RED to indicate the batteries are charging.
3. When the batteries have charged, the LED will change to
GREEN.
Battery Low Alert
When the icon blinks on the display, the battery level is low
and the batteries should be recharged or replaced. If the batteries
are not charged, an audio tone will then sound to warn the user
that the batteries are almost discharged.
Battery Usage
The time taken to discharge the batteries will depend on how you
use the TX670. The 1500 mAh battery pack supplied is powerful
enough for a full days use under average conditions.
Conserving Battery Power
The TX670 has built-in power saving features to help you get the
maximum amount of time between charges. If you need to operate
your TX670 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 batteries.
Standby Mode
The TX670 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 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.
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.
