PAGE 2 INSTRUCTION MANUAL BX SERIES HANDHELD


INTRODUCTION

The BX Series handhelds are rugged, easy to operate, full featured commercial radios and

come in 3 model versions:

• BX710 operating in 146-174 MHz VHF band

• BX720 operating in 450–490 MHz UHF band

• BX730 operating in 476.4–520 MHz UHF band

The rugged assembly has a single diecast frame housed in a polycarbonate alloy case.

The signal is usually considered 'line-of-sight'. Generally the range of your

BX Series radio will vary according to your location and the height of your antenna.

UHF and VHF signals are easily blocked by hills or large buildings so you won’t get as much

range in a valley or built-up city areas as you will from a hilltop or in open country. If you are

having trouble with reception, try moving to an open space or a higher location. The typical

portable range is around 3 to 5 km depending on the terrain. Moving to a higher location or

using a repeater will extend the range.

GETTING STARTED

Your BX Series handheld is supplied with a 7.4 Volt 1700 mAh Li-ion rechargeable battery

pack. When the battery is new, your handheld battery pack will need to be charged. If you

have not used your BX Series handheld for some time, you will need to recharge the battery

pack before use.

The battery pack is a sealed unit and contains no user serviceable parts.

WARNING: Use only GME approved battery packs and chargers. The use of other types may

be dangerous and will void the warranty.

To fit the battery pack

1. Locate the bottom of the battery pack into the two slots in the base of the radio frame.

2. Press the top of the battery pack into place against the radio until it ‘clicks’.

To remove the battery pack

1. Slide the battery retaining clip downward while pulling the top of the battery away

from the radio.

2. Lift the battery pack upward to clear the slots at the bottom of the radio.

Low battery indicator

Maintaining your battery pack

When the battery voltage drops to around 6.1 Volts, your BX Series handheld will give one

beep. The battery indicator will flash on the display and the TX/Busy LED will blink to

indicate that the battery needs to be charged. You should recharge the battery pack as soon

as possible. If you have been transmitting using the 'Hi' Power setting, you can extend battery

life by switching to 'Lo' Transmit power.

Battery charging

Your BX Series handheld is supplied with an AC adaptor and desktop fast charger. The charger

will charge a fully discharged 1700 mAh battery pack to full capacity in around 1-2 hours.

1. Plug the charger into a standard 240 Volt AC outlet.

2. Plug the lead from the charger into the charging cradle.

3. Place the BX Series handheld into the cradle. The RED LED will light to indicate the

battery is charging.

4. When the battery has charged, the LED will change to GREEN.

Battery usage

The time taken to discharge the battery pack will depend on how you use your BX Series

handheld. The 1700 mAh battery pack is powerful enough for a full days use under

average conditions.

Conserving battery power

USE ONLY GME APPROVED CHARGERS.

The use of other types may be dangerous and will void warranty.

DO NOT connect your vehicle's 13.8 Volt battery supply to

the charging socket as damage will result.

The BX Series handheld has built in power saving features to help you maximise the amount

of time between charges from your Li-ion battery pack. If you need to operate your handheld

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.

Sleep Mode: The BX Series handheld will automatically enter the ‘Sleep’ mode after around

10 seconds of inactivity (i.e. no transmission or reception).While sleeping, it will still check

for incoming signals but it will draw only about one fifth of the power from the battery. As

soon as a signal is received or any keys are pressed, the radio will wake up again. This sleep

function is automatic and by itself can greatly extend the battery life in standby mode by

many hours.

Scanning: The BX Series handheld 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. You can squeeze that extra bit of life from the battery by avoiding any

unnecessary scanning. In addition, scanning several channels increases the chance of finding

a signal thereby keeping the receiver awake and the squelch open.

Low Transmit Power Setting: The transmitter has both 'Hi' and 'Lo' 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 'Lo' Transmit power setting. This reduces the transmitter power

to 1 Watt.

TURNING THE radio ON/oFF

Standard Functions

Rotate the volume control clockwise past the 'click' to turn the radio ON. Rotate the control

fully counter clockwise past the 'click' to turn the radio OFF.

Adjusting the receiver volume

While receiving a signal, rotate the volume control to achieve a comfortable listening level.

If there are no signals present, press the Squelch key briefly (if available) to open the

squelch, then adjust the volume while listening to the receiver's background noise. When

finished, briefly press the Squelch key again to return the receiver to the quiet state.

Note: The minimum setting of the volume control has been factory preset so that, even with

the volume turned right down, you can still safely listen to an incoming signal with your ear

against the speaker (telephone style).

Selecting Channels

To change channels briefly press the key to step up one channel or the key to step

down one channel.

Press and hold the or keys to quickly scroll through the channels. There is a maximum

of 128 channels available.

Activating the backlighting

Your BX Series handheld LCD features built-in backlighting. The backlighting is normally

switched OFF to conserve battery power but will switch ON automatically when any key

is pressed.

Transmitting

Before transmitting, check to see if the channel is already in use ('BUSY' will be displayed and

the LED on the top of the radio will be green or orange). If the channel is busy, you should

wait until it is clear before transmitting.

To transmit, press the Push-To-Talk (PTT) switch on the left-hand side of the radio. Hold

the radio about 5-8 cms from your face with the antenna vertical and speak into the built-in

microphone located just below the speaker. When talking, speak at a normal voice level. The

microphone is quite sensitive so it is not necessary to raise your voice or shout.

Receiving

Note: Your radio may be programmed with options that could affect the way your radio behaves

when it receives a call from another radio.

Normal Reception

Your radio will normally be muted (squelched) so that it is quiet when there are no signals. When a

transmission is received, the radio will automatically unmute itself to allow you to hear the call. When

receiving a signal, adjust the volume control as desired for a comfortable listening level.

The BUSY Indicator

Whenever the channel is active, 'BUSY' will be displayed and the LED on the top of the radio will

be green or orange. However, depending on the muting options selected on your radio, you may

not always hear any sound from the speaker. This can happen when others are sharing the channel

but their calls are not meant for you. For this reason it is important that you visually check that the

channel is not busy before making a call to ensure you do not accidentally talk over someone else.
