Operator Manual

for SM50 Mobile Radio

This operator manual contains the information needed to identify the con-

trols and visual indicators, operate, and troubleshoot the SM50 mobile

radio.

Information about the radio’s visual and audible indicators is

highlighted and illustrated with icons.

Information about radio safety, mounting, licensing, and other issues to

be considered before operating the radio are contained in the SM

Series Installation/Licensing Guide (Motorola part number [68 no.]).

The guide should be included in the shipment with your radio. If you

need a replacement of the Installation/Licensing Guide or this Operator

Manual, please contact your local Motorola dealer or distributor.

Operational Safety Information

Read this information before using your mobile radio. For the safe and efﬁcient

operation of your mobile radio, observe these guidelines.

Safe Mounting of the Radio

CAUTION: The bottom surface of the radio can become hot. Avoid contact during pro-

longed use. Do not mount where the bottom surface can come in contact with skin.

Exposure to Radio Frequency Energy

Your radio consists of a transmitter and receiver. When it is ON, it receives, and also

sends out, radio frequency (RF) energy. The radio operates in the frequency range

of VHF and UHF and employs analog modulation techniques. The power level can

range from low to high power.

In 1991 the Institute of Electrical and Electronics Engineers (IEEE), and in 1992 the

American National Standards Institute (ANSI) updated the 1982 ANSI Standard for

safety levels with respect to human exposure to RF energy. Over 120 scientists,

engineers, and physicians from universities, government health agencies, and

industry, after reviewing the available body of research, developed this updated

Standard. In March, 1993, the Federal Communications Commission (FCC) pro-

posed the adoption of this updated Standard. The design of your radio complies with

this updated Standard. If you want to limit RF exposure even further, you may

choose to control the duration of your transmissions.

Antenna Safety

Mobile radio antennas are not insulated and emit RF energy. Touching the antenna

while the radio is in use can cause burns. For your own safety and the safety of others:

DO NOT operate your mobile radio when a person is within 2 feet (0.6 meter) of the

antenna unless that person is shielded from the antenna by a metal surface such as

the roof of the car.

DO NOT allow the antenna to touch exposed parts of the body, especially the face or

eyes, while the radio is turned on.

DO NOT operate the radio with a damaged antenna. Replace a damaged antenna

immediately.

Unauthorized antennas, modiﬁcations, or attachments could damage the radio and

may violate FCC regulations. Use only the supplied or approved antenna.

Operational Safety Information

Driving

Check the laws and regulations on the use of communication devices in the areas

where you drive. Always obey them. Also, when using your radio while driving, please:

• give full attention to driving

• use hands-free operation, if available

• pull off the road and park before making or answering a call if driving con-

ditions so require.

Blasting Areas

To avoid interfering with blasting operations, turn your radio OFF when in a “blasting

area” or in areas posted: “turn off two-way radio.” Construction crews often use

remote-control RF devices to set off explosives.

Potentially Explosive Atmospheres

Turn your radio OFF before entering any area with a potentially explosive atmo-

sphere. It is rare, but your radio or its accessories could generate sparks. Sparks in

such areas could cause an explosion or ﬁre resulting in bodily injury or even death.

Areas with a potentially explosive atmosphere are often, but not always, clearly

marked. They include: fueling areas such as gas stations, below deck on boats, fuel

or chemical transfer or storage facilities, and areas where the air contains chemicals

or particles, such as grain, dust, or metal powders.

Do not transport or store ﬂammable gas, liquid, or explosives in the compartment of

your vehicle which contains your radio or accessories.

For Vehicles Powered by Liquid Petroleum (LP) Gas

Vehicles powered by LP gas (such as propane or butane) must comply with the

National Fire Protection Standard (NFPA-58). For a copy of this standard, contact

the National Fire Protection Association, One Batterymarch Park, Quincy, MA

02269, Attn: Publications Sales Division.

Children

Do not allow children to play with your radio. It is not a toy. Children could damage

the radio or injure themselves.

If the channel is busy when you try to transmit, a series of low-pitched

tones sounds until you release the PTT.
