SAFETY INFORMATION
The XRS-660 is a radio transmitting device.
• When transmitting, keep the antenna more than 25 mm from any part of the
head or body.
• Do not transmit near electrical blasting equipment or in explosive
atmospheres.
• Do not allow children to operate a radio transmitter unsupervised.
IMPORTANT INFORMATION CONCERNING UHF CB RADIO
The use of the Citizen Band radio service is licensed in Australia by the ACMA
Radiocommunications (Citizens Band Radio Stations) Class Licence and in New
Zealand by the Ministry of Economic Development New Zealand (MED). A General
User Radio Licence for Citizens Band radio and operation is subject to conditions
contained in those licences. The class licence for users and equipment operating
in the CB/PRS 477 MHz band has been amended. This radio meets the new 80
channel standard.
In simple terms the same amount of spectrum is available; however, radio
transceivers can now operate in a narrower bandwidth and hence use less
spectrum per channel. These radios are generally referred to as narrowband
or 12.5 kHz radios. By using 12.5 kHz channel spacing instead of 25 kHz, the
40 channels originally allocated can now be expanded to 80 channels thereby
doubling the channel capacity and relieving congestion in the UHF CB/PRS band.
Older 40 channel wideband radios will continue to operate on the original 40
channels, however they will not be able to converse on the newer channels
41 – 80.

XRS-660 7
The newer narrowband radios will be able to converse with all older 40 channel
wideband radios on all channels 1 – 40 as well as the newer channels allocated
from 41 – 80.
The mixing of narrowband and wideband radios in the same spectrum may
possibly cause operating issues of interference and varying levels of received
volume. For example, when a new narrowband radio receives a transmission from
an older wideband radio the speech may sound loud and distorted. Alternatively,
when an older wideband radio receives a signal from a new narrowband radio, the
speech may sound quiet. In each case, simply adjust your radio volume for best
performance.
Depending on how close your receiving radio is to another transmitting radio,
there might be interference from the transmitting radio if it is using a channel
adjacent to the channel you are listening to. Simply switch up or down a few
channels from the currently selected channel.
The above situations are not a fault of the radio but a symptom of operating
wideband and narrowband radios in the same bandwidth. These minor issues
should decrease over time as the population of wideband radios ages and
decreases.
Further information and updates are available from the Australian
Communications and Media Authority (ACMA) at www.acma.gov.au and the
Ministry of Economic Development (MED), Radio Spectrum Management at
www.rsm.govt.nz.
EMERGENCY CHANNELS
The ACMA has allocated channels 5/35 for emergency use only.
Channel 5 is the primary Simplex Emergency Channel. Where a channel 5 repeater
is available, you should select Duplex on channel 5.
Channel 35 is the input channel for the channel 5 repeater. Therefore channel 35
should also not be used for anything other than emergency transmissions.

XRS-660
8
TELEMETRY CHANNELS
ACMA regulations have allocated channels 22 and 23 for telemetry-only
applications and have prohibited the transmission of speech on these channels.
Consequently the radio has a transmit inhibit applied to channels 22 and 23.
In the event that additional telemetry/telecommand channels are approved by
the ACMA, these channels shall be added to those currently listed where voice
transmission is inhibited. Currently, transmissions on channels 61, 62 and 63 are
also inhibited and these channels are reserved for future allocation.
IMPORTANT ADVICE
• Read all instructions carefully and completely before operating your radio and
retain this manual for future reference.
• Never connect the radio to a power source other than the supplied battery.
This may damage your radio.
• Do not place your radio in front of a vehicle airbag.
• Do not use your radio with a damaged antenna.
• Do not attempt to modify your radio in any way.
• Always charge your radio at normal room temperature.
• Always switch o your radio where notices restrict the use of two-way radio
or mobile telephones.
• Use only GME approved rechargeable battery packs with the supplied
charger.
• Avoid storing or charging your radio in direct sunlight.
• Avoid storing or using your radio where temperatures are below -20°C or
above +60°C.

CONSERVING YOUR BATTERY
The XRS-660 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.
Low Transmit Power setting
The transmitter has High, Low and Ultra-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 or Ultra-Low transmit power settings. These
reduce the transmitter power from a High power of 5 Watts down to 1 Watt for
the Low setting and 100mW for the Ultra-Low setting, signicantly extending the
available ‘talk’ time.
Power Saving mode
The Power Saving function is designed to conserve power and extend the battery
life by allowing the radio to sleep during periods of inactivity. The LOW Power
Saving setting will respond more quickly to incoming signals while the HIGH
Power Saving setting will conserve the most amount of power but may not be
as responsive to incoming signals. The XRS-660 will automatically enter the
Power Saving mode after around 5 seconds of inactivity (i.e. no transmission or
reception). As soon as a signal is received or any keys are pressed, the XRS-660
will wake up again. This sleep function is automatic and by itself can greatly
extend the battery life in standby mode by many hours.
Backlight
Turning the LCD backlight o will conserve the most amount of power or using the
Auto setting for LCD backlight will turn it o after a few seconds of inactivity.
Quiet mode
If QUIET mode is selected, the radio will remain ‘muted’ on Quiet channels even if
they are busy unless your SelCall Ident is received.

XRS-660
18
Scanning
The radio draws more power from the battery when scanning than when
monitoring a single channel. This is because it must wake more often to
monitor each channel for activity. Battery life can be extended by avoiding any
unnecessary scanning. In addition, scanning several channels increases the chance
of nding a signal thereby keeping the receiver awake and the Squelch open more
often.
General
Continuously monitoring a busy channel will reduce the battery life because
incoming signals will keep the receiver awake and the Squelch will stay open for
longer periods of time. This will draw much more power from the battery pack. If
you are expecting to receive a SelCall on a busy channel, program that channel for
‘Quiet’ operation and select the Quiet mode. The radio will then stay ‘muted’ until
your SelCall Ident is received.
GENERAL
ON/OFF AND VOLUME
Rotate the Volume Knob clockwise past the ‘click’ to switch the radio on.
Continue to rotate the Volume Knob clockwise to increase the volume.
Rotate the Volume Knob counter-clockwise to decrease the volume. Continue to
rotate the Volume Knob counter-clockwise past the ‘click’ to switch the radio o.
NOTE: At the minimum volume setting there is still sucient volume to be heard
in a quiet cabin environment.
SELECTING CHANNELS
To select a channel, press the or key. Press to select a higher channel
or to select a lower channel. The selected channel is displayed on the display.
Press and hold either key to advance quickly through the channels.

XRS-660 19
SQUELCH
The Squelch is used to eliminate any annoying background noise when there are
no signals present. The Squelch can be opened or closed using the Squelch key
which is by default assigned to the press and hold function of the XRS1 key.
When the Squelch is open the receiver’s background noise can be heard and the
icon is displayed. When the Squelch is closed the receiver remains quiet while
there are no signals present but any incoming signals will override the Squelch
and be heard in the speaker.
ADJUSTING THE SQUELCH LEVEL
The Squelch sensitivity level has been factory set to provide optimum performance
under most operating conditions. If required, the sensitivity level can be adjusted
to suit changing conditions.
To adjust squelch sensitivity:
1. Press the MENU key.
2. Navigate to RADIO SETTINGS > SQUELCH LEVEL.
You can use the or key to adjust the squelch level.
The default squelch sensitivity level is 2.
SIGNAL METER
The signal meter indicates the relative strength of the incoming signal in numerical
format. Signal strengths are displayed on the right of the Channel Display in values
from 0 to 9. Signals above strength 9 are displayed as 9+.
BRIGHTNESS
The Colour LCD display is backlit for easier viewing under a wide range of lighting
conditions. The backlight will dim if no keys are pressed for a period of time to
conserve battery. The brightness level can be smoothly adjusted in steps from 0
to 10.
To adjust brightness level:
1. Press the MENU key.
2. Navigate to USER INTERFACE > BRIGHTNESS.
You can use the or key to adjust the brightness.

XRS-660
20
TRANSMITTING
Prior to transmitting, always check the channel is clear. This can be done by
listening to the channel or by visually checking that the icon is not visible or
the signal meter is not indicating a signal.
To transmit:
1. Press the PTT on the microphone. The icon will appear and the LED
indicator on the upper edge of the radio will illuminate red.
2. Hold the microphone about 3-5 cm from your face and speak at a normal
voice level. Since the microphone is quite sensitive, it is not necessary to
raise your voice or shout.
3. Release the PTT when you have nished talking, the icon and red
LED will disappear.
Always listen to ensure the channel is free before transmitting.
A Dim function can also be assigned to one of the programmable XRS keys to
quickly switch the brightness level to minimum for low light viewing. This saves
having to manually readjust the brightness level when moving into low light
environments.
To assign the Dim function to a key, press the MENU key and navigate to PROG
BUTTONS and its options to congure this feature.
To adjust the display dim timeout:
1. Press the MENU key.
2. Navigate to USER INTERFACE > DISPLAY DIMS.
You can use the or key to adjust the time before the display dims in
seconds.
