You can also arrange to send SelCalls to every tenth radio
by setting the second digit to A.
e.g.
Sending Ident 145A5 will call radios 14505, 14515, 14525,
14535.. --> 14595
Call acknowledge in Group mode
There is no call acknowledge when sending group calls.
This is to prevent all the radios in your group from trying to
respond to your SelCall transmission at the same time.
Storing Group Call Idents
Group Call Idents can be stored in memory in the same way
as a standard SelCall Ident.
Receiving Group Calls
Receiving a Group Call is identical to receiving a normal
SelCall except that the alarm sound is a LOW tone beep
instead of the normal HIGH tone beep. The Callers’ Ident or
ALPHA Name appears on the display in the usual way.
INSTALLATION
The TX3345 main unit is supplied with a slim, U-shaped
mounting cradle. The cradle can be screwed or bolted in
any convenient location in your vehicle (under or above
the dash, on the centre console, etc.) using the mounting
slots provided in the cradle. The TX3345 contains a built-in
speaker, and should be installed in a convenient location in
the vehicle’s cabin as the radio’s loud speaker. Alternatively
it can be installed in a less audible location and an
extension speaker used instead.
The LCD Controller Microphone comes complete with
a mounting clip. Its small size and light weight design
allows it to be mounted in almost any convenient position
accessible to the driver.
When installing the radio, avoid mounting it close to
heaters or air conditioners. Screw the LCD Controller
Microphone’s clip to a firm surface. Fit the TX3345 into the
cradle and tighten the gimbal knobs. Place the LCD Control-
ler Microphone in its mounting clip. Finally, plug the LCD
Controller Microphone into the front panel of the TX3345
and the power and antenna leads to the sockets provided
on the rear of the radio.
ANTENNA INSTALLATION
It is essential to select a good quality, high efficiency, 477
MHz antenna. A poor quality antenna or one not designed
for the specific frequency band you are using will give very
poor performance.
GME have a wide range of suitable 477 MHz UHF CB
antennas to suit most installations and applications. We
recommend contacting your local GME retailer for advice.
Connect to the antenna cable to the rear antenna socket
using a PL259 coaxial connector.
Noise Suppression
The inherent design of FM transceivers result in a high
level of resistance to ignition and electrical interference.
However in some installations it may be necessary to
take additional steps to help reduce or eliminate noise
interference. During installation, try to route the DC battery
leads, the antenna lead or any accessory wires away from
the engine compartment, ignition or alternator wiring. If the
noise continues, try fitting a suppression kit in which case
we recommend you consult an auto electrician for advice
specific to your installation.
Higher frequency electrical interference caused by electric
motors can be suppressed directly at the motor terminals.
