If programmed, the radio transmits a DTMF identifica­tion code (unit ID), indicating which portable is in oper­ation.

During a conversation, the code is normally sent only
on the initial PTT press (unless PTT ID has been dis­abled). The ‘TX’ indicator lights for the duration of the
PTT ID. If there is no PTT or receive activity for 7 sec­onds, or if you change the frequency or channel (or
scan resumes), the PTT ID is once again transmitted
on the next PTT press.

Setting Squelch Level

An open (low) squelch level sets the threshold for the
receiving signal strength to be low. This means that
the radio would receive a great variety of signals, both
weak and strong. A tighter (higher) squelch level
raises the threshold, thus filtering weak signals and
only accepting the stronger ones. To set the squelch

Scan Operations

Scan Operations

Scan operation tells the radio to monitor a number of
frequencies or channels. When there are some activi­ties at a particular frequency or channel, the radio
stops scanning and changes to that frequency or
channel.

Scan modes supported by the radio are:

(i) Programmable Band scan (MHz mode)
(ii) Memory Channel scan (Memory mode)

Each frequency or channel is given the same prior­ity i.e.

scan.

IMPORTANT

NOTE

The radio will not recall the scan state if it is pow­ered off while scanning.

Programmable Band Scan

In the MHz mode, the radio scans over a prepro­grammed range of frequencies usually specified in
memory channels 19 and 20.

NOTE

User can specify the frequency range for scanning
by programming the frequency limit into memory
channel 19 (usually the lower limit) and memory
channel 20 (usually the upper limit) (see

range, the radio starts scanning from that fre­quency, otherwise, it starts from the frequency
specified by memory channel 19 (or the lowest fre­quency in the band if channel 19 is blank).

NOTE

NOTE

When the ‘SCAN’ indicator flashes, scanning is in

IMPORTANT

If both memory channels are left blank (unpro­grammed), the radio scans the entire frequency
band. If channel 19 is programmed but channel 20
is blank, the upper frequency limit becomes the
highest frequency in the band. If channel 20 is pro­grammed but channel 19 is blank, the lower fre­quency limit becomes the lowest frequency in the
band. If the frequency stored in channel 19 is lower
than that stored in channel 20, then scan proceeds
in an incrementing order otherwise, scan proceeds
in a decrementing order.

Information For Safe, Efficient Operation

Information For Safe, Efficient Opera­tion

Exposure To Radio Frequency Energy

In August 1996 the Federal Communications Commis­sion (FCC) adopted updated RF energy exposure
guidelines for wireless products regulated by the FCC.
Those guidelines are consistent with the safety stan­dards* previously set by both U.S. and international
standards bodies. The design of your Motorola two­way radio complies with the FCC guidelines and these
standards.

*American National Standards Institute (C95.1 - 1992);
*National Council on Radiation Protection and Measure-

ments (NCRP-1986);

*International Commission on Non-Ionizing Radiation Pro-

tection (ICNRP- 1986)

To assure optimal radio performance and to insure that
exposure to RF energy is within the guidelines in the
above standards, the following operating procedures
should be observed:

For Portable Two-way Radios:

• For hand held operation, the radio should be held

in a vertical position with the microphone one to
two inches (2.5 to 5 cm) away from the mouth,
and the antenna should be kept one to two
inches (2.5 to 5 cm) from the head or body when
transmitting.

• For body worn operation, the antenna should be

kept at least one inch (2.5 cm) from the body
when transmitting.

62

2-Year Warranty

Information For Safe, Efficient Operation

Electromagnetic Interference/compatibility

Nearly every electronic device is susceptible to elec­tromagnetic interference (EMI) if inadequately
shielded, designed or otherwise configured for electro­magnetic compatibility.

• Turn your radio OFF in any facilities where
posted notices instruct you to do so. Hospitals or
health care facilities may be using equipment that
could be sensitive to external RF energy.

• Turn your radio off when on board aircraft when
instructed to do so. Any use of the radio must be
in accordance with Federal Aviation Administra­tion (FAA) and FCC regulations or crew instruc­tions.

• Do not use the radio with a damaged antenna. If

CAUTION

a damaged antenna comes into contact with the
skin, a minor burn may result.

• All batteries can cause proper ty damage, injury
or burns if a conductive material such as jewelry,
keys or beaded chains touches exposed termi­nals. The material may complete an electrical cir­cuit (short circuit) and become quite hot.
Exercise care in handling any charged battery,
particularly when placing it inside a pocket, purse
or other container with metal objects.

Potentially Explosive Atmospheres

Areas with potentially explosive atmospheres are
often, but not always, clearly marked. They include
fuelling areas such as below deck on boats, fuel or
chemical transfer or storage facilities; areas where the
air contains chemicals or particles, such as grain,
dust, or metal powders; and any other area where you

2-Year Warranty

63

Information For Safe, Efficient Operation

would normally be advised to turn off your vehicle
engine.

• Turn your radio OFF when in any area with a
potentially explosive atmosphere, unless it is a
type especially qualified for such use (for exam­ple, FMRC Approved). Sparks in such areas
could cause an explosion or fire resulting in
bodily injury or even death.

• Do not replace or charge batteries in a hazard­ous atmosphere. Contact sparking may occur
while installing or removing batteries and cause
an explosion.

Blasting Caps And Areas

WARNING

WARNING

To avoid possible interference with blasting opera­tions, turn your radio OFF near electrical blasting
caps or in a “blasting area” or in areas posted: “Turn
off two-way radio”. Obey all signs and instructions.

For Vehicles With An Air Bag

WARNING

An air bag inflates with great force. Do not place
objects, including portable or mobile two-way
radios, in the area over the air bag or in the air bag
deployment area. If improperly installed or placed
wireless equipment is in the air bag deployment
area and the air bag inflates, serious injury could
result.

Recycling / Disposal of NiCd Batteries

The U.S. En vironmental Protection Agency (EPA) clas­sifies used NiCd batteries as hazardous waste, unless
certain exemptions apply.

At the end of your battery’s useful life, it can be recy­cled. However, recycling facilities may not be available
in all areas. Under various state or local laws, such
batteries must be recycled or disposed of properly,
and cannot be dumped in landfills or incinerators.

Troubleshooting

Possible Problem (3): The batter y life is based on a

duty cycle where the radio is transmitting
5%, receiving 5%, and in standby mode
90% of the time. Usage that differs from this
will change the typical battery life expect­ancy accordingly.

Solution :If you use your radio for a longer period

of time than the standard duty cycle, you
may need to recharge your battery again.

Possible Problem (4): Battery or charger contacts may

be dirty.

Solution :Clean battery and charger contacts

often.

Alkaline Battery does not last long enough (<10
minutes).

Possible Problem (1): Operating the radio at high

power with alkaline batteries.

Solution :When used with alkaline batteries, the

radio should operate at low power
unless absolutely necessary.

NOTE

It is recommended to operate your radio in Low
Pow er when using alkaline batteries. Using alkaline
batteries in High Power might result a

Alert

(3 low pitched tones) shortly after transmitting.
This is NOT a malfunction. The alert sounds
because alkaline batteries cannot maintain the
power needed to transmit at High Power for a long
interval. However, APC is immediately activated
when this alert sounds. It automatically adjusts the
radio’s power requirements to maintain the radio’s
operation. Without APC, the radio would instead
reset itself and refuse to transmit.

Troubleshooting

Radio will not talk to other radios in system.

Possible Problem (1): Radios may be on different fre-

quencies, or having different Coded
Squelch Codes.

Solution :Verify that frequencies and Coded

Squelch Codes are the same for all
radios in your talk group.

Hearing other conversations or noise on your radio.

Possible Problem (1): Users do not have exclusiv e use

of frequencies. Frequencies must be shared
using proper radio etiquette.

Solution :Use proper radio etiquette.

NOTE

transmitters. External magnetic mount
antennas are recommended for best
range when communicating in an auto­mobile. If the radio supports the High/

Troubleshooting

Possible Problem (2): Operating the radio while it is

close to your body (i.e. in a pocket or on a
belt) and while you are using audio acces­sories decreases its range because of the
shielding effect of your body.

Solution :The higher the radio is held, the better

the talk range. Use of audio accessories
is only recommended in close range sit­uations for best results.

Possible Problem (3): The Carrier Squelch Level may

be set too high.

Solution :Set the Carrier Squelch Level to a lower

value (see “Setting Squelch Level” on
page 20).

You hear constant static from speaker.

Possible Problem (1): The alkaline batteries may be

weak (or the NiCd battery may be dis­charged).

Solution :Press and hold the PTT while looking at

the LCD. If the ‘BATT’ indicator flashes
continuously while still holding the PTT,
the batteries should be replaced or
recharged.

Possible Problem (2): When using your radio around

computers or electronic equipment, you
may hear static or interference from these
devices.

Solution :Enable Coded Squelch. Coded squelch

screens out this type of interference (see
“Changing Squelch Modes” on page 18).
