PAGE6 INSTRUCTIONMANUAL BXSERIESHANDHELD
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
The BX Series handheld has built in
power saving features to help you
maximise the amount of time between
chargesfromyourLi-ionbatterypack.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
cansqueezethatextrabitoflifefrom
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.
GENERAL OPERATION
power on/oFF
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 voLume
While receiving a signal, rotate the
volume control to achieve a comfortable
listening level. If there are no signals
present, press the MON 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 MON 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).
dispLay Lighting
Your BX Series handheld LCD features
built-inbacklighting.Thebacklighting
is normally switched OFF to conserve
battery power but will switch ON
automatically when any key
is pressed.
seLecting channeLs
1. In the ‘standby’ mode press the key
to step up one channel and the key
step down one channel.
2. Press and hold the or keys to
quickly scroll through the channels.
receiving signaLs
NOTE: Your radio may be programmed
with options that could affect the way
your radio behaves when it receives a
call. The description below is therefore
general and should apply to
most situations.
When the BX Series handheld is not
receiving signals it will remain in the
standby mode to conserve power. During
this time the receiver is normally muted,
the LED ‘Busy’ indicator on the upper
edge of the radio is not lit and the ‘Save’
indicator flashes on the display.
BX SERIES HANDHELD INSTRUCTION MANUAL PAGE 7
When a signal is received, the ‘Busy’
indicator will light Green and the signal
will be heard in the speaker. Adjust
the volume control as desired for a
comfortable listening level.
If the incoming signal is encoded with a
CTCSS tone that matches the one set in
your radio, the ‘Busy’ indicator will light
Orange and the signal will be heard in
the speaker. If the ‘Busy’ indicator lights
Green but you cannot hear the signal
(and the volume control is correctly
adjusted) it is likely your radio has CTCSS
enable but the incoming signal is not
using your selected CTCSS tone
(see MODE settings for CTCSS options).
In this way the radio can ensure you are
not disturbed by signals that were not
meant for you. If you wish to temporarily
listen to the encoded signal, press the
MON (Squelch) key.
Once no further signals are received, the
unit will return to standby mode.
transmitting
Important: Before transmitting,
check to see if the channel is
already in use (i.e. the ‘Busy’
indicator is lit). If the ’Busy’
indicator is Green or Orange, the
channel is busy. You should wait
until the channel is clear before
transmitting.
Totransmit,pressandholdthePush-
To-Talk(PTT)switch.Holdtheunit5-8
cm from your mouth with the antenna
verticalandspeakintothebuilt-in
microphone. While the PTT is pressed
the ‘Busy’ indicator will light Red.
When you have finished speaking,
release the PTT switch to receive
incoming signals again (you cannot
transmit and receive at the same time).
If no further signals are received the unit
will return to standby mode.
Note: The other radio you are calling
must be set to the same channel
as yours.
Transmitting a ‘Call Alarm’ Melody
The PTT switch can be used to transmit a
‘Call Alarm’ to another radio on the same
channel. The Alarm melody will be heard
in the speaker of the other radio to alert
them to your call. To use this feature the
‘Call Alarm’ option in your radio must be
enabled through the MODE settings.
To send the ‘Call Alarm’ melody, press
the PTT switch TWICE quickly. The
‘Busy’ indicator will light Red for several
seconds and the Alarm melody will
beheardinyourspeaker-andinthe
speaker of the radio you are calling.
transmitter range
The signal range on the VHF/UHF
frequency bands used by the BX series
handhelds is generally considered to be
‘line-of-sight’.Generallytherangewill
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 will get less range in a
valleyorbuilt-upcityareathanyouwill
from a hill top or open country. If you are
having trouble with reception, try moving
to an open space or a higher location. If
you can receive but are having difficulty
transmitting back, try using the ‘Hi’
power setting on the transmitter to
ensure maximum range is available.
squeLch (mon) key
The Squelch (MON) key serves a dual
function that controls both the Squelch
and CTCSS.
Squelch
To open the squelch briefly press the
MON key. This will allow you to check
the current channel for activity before
transmitting, particularly if you have
CTCSS enabled. When the squelch is
open the ‘Busy’ indicator will light Green
and you will hear static or hiss if the
channel is clear. Do not transmit if you
hear any conversations.
Briefly press the MON key again to close
the squelch.
CTCSS/DCS
Note: For a description of the CTCSS
and DCS features please refer to the
MODE Key section later in this manual.
If you have one or more channels
programmed with CTCSS or DCS codes,
select one of these channels and press
and hold the MON key to globally
activate or deactivate CTCSS/DCS on
the radio. When CTCSS/DCS is activated,
‘CTC’ or ‘DCS’ will appear on the display
PAGE 8 INSTRUCTION MANUAL BX SERIES HANDHELD
along with the selected CTCSS/DCS code.
When deactivated the CTCSS/DCS code
willbedisplayedas‘---‘
Note: If your radio does not have any
channels programmed with CTCSS/DCS
codes or you have selected a channel
that does not have a CTCSS/DCS code,
this function will be ignored.
scan key
The SCAN key is a dual function key
that controls both Scan and Memory
functions.
Channel scanning allows you to monitor
selected channels automatically for
incoming signals. While the radio is
scanning, the MODE key is disabled.
Before scanning you must select the
channels you wish to scan and store
them in memory
To select channels for scanning
From the standby mode;
1. Press the or keys to select the
required channel.
2. Press and hold the SCAN key until
the radio beeps. ‘M’ will be displayed
indicating the selected channel is now
stored in the Scan memory.
3. Repeat to store further channels
for scanning.
4. To remove a channel from the Scan
memory, select a channel from the
Scan memory (identified by ‘M’ on
the display) then press and hold the
SCAN key. ‘M’ will disappear from the
display and the channel will
be removed.
To scan the selected channels
Briefly press the SCAN key. ‘SCAN’ will
be displayed and the radio will show
rapidly changing channel numbers as
it scans through the channels. While
scanning, briefly press the or keys
to select the scan direction.
To stop scanning press the SCAN key
again. The radio will return to normal
operation and ‘SCAN’ will disappear
from the display.
NOTE: There must be at least TWO
channels in the scan memory otherwise
the radio will not scan.
Scanning Features
If a signal is received, the scan pauses
allowing you to transmit and receive on
that channel. The scan will resume a few
seconds after the last activity.
Press the PTT switch while scanning to
jump to the Home channel (the Home
channel is the channel the radio was
on at the time scanning was activated).
You can then transmit and receive on
that channel. The scan will automatically
resume a few seconds after the
last activity.
If the radio stops on a busy channel and
you do not wish to listen, briefly press
the or keys to ‘skip’ over the busy
channel and continue scanning.
TIP: The scan mode will reduce the
overall battery life because the standby
(battery save) feature is overridden. You
should avoid scanning if the battery is
running low and you need to
conserve power.
keypad Lock
The Keypad Lock feature disables the

1. CTCSS CODE SELECTION
The Continuous Tone Coded Squelch
System (CTCSS) is a squelch quieting
system that allows groups of users
to share the same channel without
disturbing each other. It uses 1 of 38 low
frequency tones to open and close the
squelch on the radio. The CTCSS tones
do not prevent others from hearing your
transmission. They simply provide you
with a quieter channel by preventing
you from hearing transmissions that are
not using the same tone as you and are
therefore not directed at you.
NOTE: To communicate with other radios
using CTCSS, all radios you wish to
communicate with must be on the same
channel and have the same CTCSS code
selected. If you wish to receive signals
from others who are not using CTCSS
you will need to either disable CTCSS
or set the CTCSS code to ‘oFF’ on that
channel (as described below).
To select a CTCSS code
From the standby mode;
1. Select the required channel using the
or keys.
2. Press the MODE key ONCE. ‘CTC’ will
flash on the display.
3. Press the or keys to select
the required CTCSS tone (a list of
available tone codes is provided at the
end of this manual). To turn CTCSS off

indicating CTCSS has been globally
deactivated on the radio.
2. DCS (DIGITALLY CODED SQUELCH)
Digitally Coded Squelch (DCS) is also a
squelch quieting system similar to CTCSS
that allows user groups to share the
same channel without disturbing each
other. There are 104 DCS codes available.
To select DCS on the radio
From the standby mode;
1. Select the required channel using the
or keys.
2. Press the MODE key TWICE. ‘DCS’
will flash.

but the radio will continue to switch
to the Dual Watch channel at regular
intervals to listen for signals resulting in
short breaks in the conversation on the
selected channel.
If a signal is received on the Dual
Watch channel, the radio will pause
on that channel to allow the signal to
be heard but will regularly switch back
to the selected channel to listen for
signals resulting in short breaks in the
conversation on the Dual Watch channel.
Once the channel has become clear for a
few seconds the Dual Watch function will
resume normally.
If you wish to talk when either channel

signals. If no signals are present it will
immediately return to the ‘selected’
channel and the cycle will be repeated.
During this time, signals received on the
‘selected’ channel can be heard in the
usual way but the radio will continue to
switch to the Priority channel every few
seconds, resulting in short breaks in the
reception on the ‘selected’ channel. To
talk on the ‘selected’ channel during this
time, press the PTT switch. The Priority
Scan will pause to allow you to converse
on the ‘selected’ channel. The Priority
scan will resume a few seconds after the
last activity on that channel.
If a signal is received on the Priority
channel, the radio will pause on that
channel to allow the signal to be heard
but will continue to switch back to the
‘selected’ channel every few seconds,
resulting in short breaks in the reception
on the Priority channel. To talk on the
Priority channel during this time, press
the PTT switch. The radio will remain
on the Priority channel to allow you
to continue your conversation but will
return to the ‘selected’ channel a few
seconds after the last activity on that
channel.
7. SQUELCH SETTINGS
The Squelch mode lets you adjust the
squelch sensitivity. The higher the
