Safety and compliance warnings
Radio frequency exposure information
For your own safety and to ensure you comply with the
Federal Communication Commission’s (FCC) radio
frequency (RF) exposure guidelines, please read the following
information before using this radio.
Using this radio
You should use this radio only for work-related purposes (it is
not authorized for any other use) and if you are fully aware
of, and can exercise control over, your exposure to RF energy.
To prevent exceeding FCC RF exposure limits, you must
control the amount and duration of RF that you and other
people are exposed to.
It is also important that you:
■ Do not remove the RF exposure label from the radio.
■ Ensure this RF exposure information accompanies the
radio when it is transferred to other users.
■ Do not use the radio if you do not adhere to the guide-
lines on controlling your exposure to RF.
Controlling your exposure to RF energy
This radio emits RF energy or radio waves primarily when
calls are made. RF is a form of electromagnetic energy (as is
sunlight), and there are recommended levels of maximum
RF exposure.
To control your exposure to RF and comply with the maximum exposure limits for occupational/controlled environments, follow these guidelines:
■ Do not talk (transmit) on the radio more than the rated
transmit duty cycle. This is important because the radio
radiates more energy when it is transmitting than when
it is receiving.
Safety and compliance warnings 3
Page 6
■ While you are transmitting (talking or sending data) on
the radio, you must ensure that there is always a distance
of 0.9m (35 inches) between people and the antenna.
This is the minimum safe distance.
■ Use the radio only with Tait-approved antennas and
attachments, and make only authorized modifications to
the antenna otherwise you could damage the radio and
violate FCC regulations.
Website: For more information on what RF energy is
and how to control your exposure to it, go to
http://www.fcc.gov/oet/rfsafety/rf-faqs.html.
Compliance with RF energy exposure standards
This two-way radio complies with these RF energy exposure
standards and guidelines:
■ United States Federal Communications Commission,
Code of Federal Regulations; 47 CFR 1.1307, 1.1310
and 2.1091
■ American National Standards Institute (ANSI) / Institute
of Electrical and Electronic Engineers (IEEE) C95. 1-1992
■ Institute of Electrical and Electronic Engineers (IEEE)
C95.1-1999 Edition.
This radio complies with the IEEE (FCC) and ICNIRP exposure
limits for occupational/controlled RF exposure environments
at operating duty factors of up to 50% talk to 50% listen.
Radio frequency emissions limits in the USA
Part 15 of the FCC Rules imposes RF emission limits on electronic equipment to prevent interference to reception of
broadcast services.
This device complies with Part 15 of the FCC Rules. Operation is subject to the condition that this device does not
cause harmful interference.

Basic operation 25
Page 28
Receiving a call
When you receive a call, your radio may display the caller’s
number and respond in one of two ways, depending on the
way it was programmed and the way your network operates.
■ On-air call setup: The radio gives a ring and automatically
accepts the call. The green LED glows to show that the
system has assigned a traffic channel.
■ Full off-air call setup (FOACSU): When a call is received,
the radio rings like a telephone.
To accept the call, briefly press the PTT key or lift the
microphone off the microphone clip. The green LED glows
to show that the system has assigned a traffic channel.
Once the green LED glows, you can proceed with the call, as
follows:
1 Hold the microphone about 5 cm (2 inches) from
your mouth.
2 Press and hold the PTT key to transmit.
3 Speak clearly into the microphone and release the PTT
key when you have finished talking.
While you are transmitting, the red LED glows.
4 End the call by placing your microphone back onto its
hook or by pressing the clear key . The network may
also end the call if neither you nor the other party transmits for a predetermined time or if your call time limit is
exceeded.
Transmit timer
Your radio may have a transmit timer that limits the amount
of time you can transmit continuously.
When the transmit timer is about to expire, the red LED

About emergency operation
In an emergency you may be able to summon help by sending an emergency call. After making the call, your radio may
be programmed to enter emergency mode. While emergency
mode is active, your radio may cycle between receive and
transmit, so that your dispatcher or the called party can hear
any activity near your radio.
On most networks, an emergency call takes precedence over
other call types, and existing calls are cleared down so that
the emergency call can proceed.
To make an emergency call from your radio, you may be able
to either:
■ use a function key programmed for emergency mode, or
■ make a preset emergency call. See “Making a preset call”
on page 24.
Activating emergency mode
You can activate emergency mode using a function key
programmed for emergency mode. Alternatively, you may be
able to activate emergency mode using a hidden switch or
panic button. Once emergency mode is activated, your radio
makes an emergency call to your dispatcher or some other
predetermined location. The radio then enters
emergency mode.
While emergency mode is active, your radio may cycle
between receive and transmit, so that your dispatcher can
hear any activity near the radio.
28 Basic operation
Page 31
Cancelling emergency mode
Reset the radio to normal operation at any time by turning
the radio off and then on.
Note: Emergency mode may be programmed to end after a
fixed period of time. In this case, there is no need to
turn the radio off and then on in order to return the
radio to normal operation.

1 Dial the number of the conventional channel or group
using the keys to . The number will be between
101 and 110.
2 Press the or PTT key.
Your radio switches to the conventional channel or group
programmed for that number.
Using a function key to change operating mode
Press the switch mode function key to change your operating
mode. If changing to conventional mode, the radio will start
on either a pre-programmed channel or group, or the channel or group that was previously selected.
Selecting a channel
Once in conventional mode, use the scroll keys and
to scroll through the channel list until the channel or
group you want is displayed.
Checking that a channel is clear
You or your user group may be segregated from other user
groups by special signalling. If an incoming call carries the
special signalling tones specific to you or your user group,
your radio’s signalling mute opens and you can hear the call.
The monitor function may allow you to override any special
signalling on a channel, so that you can check that the channel is clear before you make a call.
32 Operating in conventional mode
Page 35
Note: Your radio may be programmed to activate monitor
whenever the microphone is off the microphone clip.
To activate monitor you may be able to either:
■ remove the microphone from the microphone clip, or
■ use a programmed function key.
Activating monitor by using a function key
1 Press the monitor function key to activate monitor and
hear any traffic on the channel.
While monitor is on, the green LED flashes slowly.
2 Press the monitor function key again to turn monitor off,
or wait for monitor to turn off automatically, after a
programmed delay.
When monitor turns off, the green LED stops flashing.
Note: Your radio may be programmed so that monitor turns
off automatically after a short time.
Communicating directly with other radios
You can bypass the radio repeater and communicate directly
with another radio. This feature is known as repeater talkaround. You can do this, for example, when you are out of
range of the repeater, or if the repeater is busy or stops working for whatever reason.
While repeater talkaround is active, all transmissions are
made on the receive frequency of the channel you are on.
To activate repeater talkaround:
1 Change to the required channel.
2 Press the programmed function key to turn repeater talk-
around on.
3 Proceed with your call.
4 To turn repeater talkaround off, either:
■ change the channel, or
■ press the function key again.

light up when the radio is turned on, it is likely that no power
is reaching the radio. Check the following:
■ Is the power connector firmly plugged into the rear of
the radio?
■ Are the in-line fuses in good condition?
■ Is the power cable securely connected to the vehicle bat-
tery or power supply?
If all appears to be in order, then contact your radio provider
for further assistance.
