Signal Meter; Transmitting; Time-Out Timer; Backlighting - GME TX3500 Instruction Manual

SigNAl METEr

the signal meter indicates the relative signal strength of the
incoming signal. stronger incoming signals will display more
bars while weaker signals will display less bars.

TrANSMiTTiNg

Prior to transmitting, always check the channel is not being
used. this can be done either by listening or by checking that
the signal meter and the 'Busy' icon
to transmit, press the PTT switch on the microphone. the
icon will appear. hold the microphone about 5-8 cm from
your face and speak at a normal voice level. the microphone
is quite sensitive so it is not necessary to raise your voice or
shout. release the PTT when you have finished talking. the
icon will disappear.
IMPORTANT:
Always listen to ensure the channel is free
before transmitting.

TiME-OUT TiMEr

your tX3500 has an in-built time-out timer (tot) that limits
transmissions to a maximum of 3 minutes of continuous
operation. this feature is required by the AcmA to prevent the
radio from jamming the frequency if the Ptt switch has been
accidentally jammed. once the tot is triggered the radio will
beep once and the transmitter output will be switched off. If
the Ptt remains pressed, the transmit icon
visible but there will be no signal transmitted from the radio.
once the Ptt switch has been released the tot is reset and
transmissions can recommence.

BACkligHTiNg

the liquid crystal display and keys are back lit for easy
viewing at night. the back lighting remains on at while the
tX3500 is switched on.
Adjusting the backlighting
the backlighting brightness and colour can be adjusted for
personal preference. there are three settings available;
br' - Brightness Setting: Provides a continuously variable
brightness adjustment from very dim to full brightness.
PA G E 6
'cL' - Colour Setting: Provides a continuously variable colour
change via a smooth blend of red, Green and Blue
colours.
'Li' - Lightness Setting: Provides a continuously variable light-
ness or colour saturation of the selected colour from full
colour to white (no colour).
to make adjustments to the backlighting, press and hold the
Channel knob for several seconds. 'br' is displayed indicating
is not visible.
the Brightness mode is selected.
Briefly press the Channel knob to step through the available
settings. 'br' (brightness), 'cl' (colour) or 'li' (lightness) will be
displayed at each press.
to adjust the current selection, rotate the Channel knob left
or right.
When finished, press and hold the Channel knob to return to
normal operation.
TIP:
For the deepest colour range, reduce the lightness
'li' setting.

BANdwidTH FilTEr SETTiNgS

the tX3500 is fitted with two user-selectable receiver
will remain
bandwidth filters which allow the receiver to be adjusted for
either wide or narrow band reception on channels 1 – 40. this
feature provides additional compatibility with older 40-channel
radios. the wide setting increases the tolerance of the tX3500
receiver to older wideband 40 channel radios or to signals that
might be slightly off frequency. the narrow setting increases
the selectivity of the receiver to help reduce interference from
strong interfering signals on adjacent channels.
