FCC LICENSING

This unit may or may not require a specific FCC license to operate.

The FCC requires that all transmitters in the conventional and some

trunked systems to be licensed by the Federal Communications

Commission. Some trunked operations now are exempt from indi-

vidual licensing requirements but may be operated in a licensed

system.

Consult your Maxon Dealer regarding specific licensing infor-

mation (Form 571), or contact the Federal Communications

Commission via phone: 888-CALLFCC (1-888-225-5322) or

through an FCC District office near you.

SAFETY INFORMATION

The operator of any mobile radio should be aware of certain

hazards common to the operation of vehicular radio trans-

missions. Possible hazards are:

Explosive Atmospheres: Just as it is dangerous to fuel a vehicle

with the motor running, be sure to turn the radio OFF while

fueling the vehicle. Do not carry containers of fuel in the

trunk of the vehicle when the radio is mounted in the trunk.

Interference To Vehicular Electronic Systems: Electronic fuel

injection systems, electronic anti-skid braking systems, elec-

tronic cruise control systems, etc. are typical of the types of

electronic devices that may malfunction due to the lack of

protection from radio frequency energy present when trans-

mitting. If the vehicle contains such equipment, consult the

dealer for the make of vehicle and enlist his aid in determining

if such electronic circuits perform normally when the radio is

transmitting.

Dynamite Blasting Caps: Dynamite blasting caps may be

caused to explode by operating a radio within 500 feet of the

caps. Always obey the "Turn Off Two Way Radio" signs

posted where dynamite is being used. When transporting

blasting caps in your vehicle:

a) Carry the blasting caps in a closed metal box with a soft

lining.

b) Leave the radio OFF whenever the blasting caps are

being put into or removed from the vehicle.

Radio Frequency Energy: To prevent burns or related physical

injury from radio frequency energy, do not operate the trans-

mitter when anyone outside of the vehicle is within two feet

of the antenna. 1

SAFETY INFORMATION, Continued

CAUTION

Before jump starting, charging or changing the vehicle battery, remove the

10A fuse located in the red lead. This will insure that the radio is protected

from damage during the battery charging process. Replace fuse when charging

is completed.

Liquefied Petroleum (LP) Gas Powered Vehicles: Mobile radio

installations in vehicles powered by liquefied petroleum gas

(with the LP gas container in the trunk or other sealed-off

space within the interior of the vehicle) must conform to

the National Fire Protection Association standard (NFPA 58)

which requires that:

a) The space containing the radio equipment shall be

isolated by a seal from the space containing the LP

gas container and its fittings.

b) Outside filling connections shall be used for the LP

gas container.

c) The LP gas container shall be vented to the outside

of the vehicle.

SAFE DRIVING RECOMMENDATIONS

FOR MOBILE RADIO USERS*

Exercise caution when using a mobile radio. Become familiar

with information on the safe operation of a mobile radio:

• Keep both hands on the steering wheel and the micro-

phone in its cradle whenever the vehicle is in motion.

• Place calls only when the vehicle is stopped. Use recall

dialing to speed the time it takes to place a call.

• When talking from a moving vehicle is unavoidable,

drive in the slower lane and keep conversations brief.

• If conversation requires taking notes or complex

thought, stop the vehicle in a safe place - then continue

the call.

* As recommended by the AAA (American Automobile Association)

OPERATING PROCEDURES

Two-way FM radio systems must be operated in accordance

with the Rules and Regulations of the Federal Communica-

tions Commission (FCC). Operators of two-way radio equip-

ment must be thoroughly familiar with the rules that apply

to the intended type of radio operation. Following these rules

will help to eliminate confusion, assure the most efficient

use of existing radio channels, and result in a smoothly

functioning radio network. When using this two-way radio,

remember these rules:

1) It is a violation of FCC Rules to interrupt any distress

or emergency message. As the radio operates in much

the same way as a telephone "party line," always listen

to make sure that the line is clear before sending

messages. If someone is sending an emergency

message - such as reporting a fire, or asking for help

in an accident - KEEP OFF THE AIR! Emergency calls

have priority over all other messages.

2) Use of profane or obscene language is prohibited by

federal law.

3) It is against the law to send false call letters, or a false

distress or emergency message.

4) The FCC requires that conversations be kept brief

and confined to business. To save time, use coded

messages whenever possible.

5) Using a radio to send personal messages (except in an

emergency) is a violation of the FCC Rules.

6) It is against Federal Law to repeat or otherwise make

known anything overheard on the radio. Conversations

between others sharing a channel must be regarded as

confidential. 4

OPERATING PROCEDURES, Continued

7) The FCC requires the operator to identify himself at

certain times by means of call letters. Refer to the rules

that apply to the particular type of operation for the

proper procedure.

NOTE: The GE-MARC and EDACS trunking environments

have automatic identification features built in and do not

require the user to identify by means of call letters.

8) No changes or adjustments shall be made to the equip-

ment except by an authorized or certified electronics

technician.

OPERATING TIPS

Operating the radio in low areas of terrain or while under

power lines or bridges will reduce the effective range of two-

way radios. These areas should be avoided whenever possible.

In areas where transmission or reception is poor, insure that

the antenna is vertical (particularly if a glass mount antenna

is used). Moving a few yards in another direction or moving

to higher ground may also help improve radio communica-

tion.

INTRODUCTION

The EM-4800 is a synthesized, microprocessor-based, FM

mobile which provides reliable two-way communications in

the Enhanced Digital Access Communications System (EDACS)

trunking environment, GE-MARC trunking system and conven-

tional communications systems.

In the EDACS or trunked system mode, the user selects a

communications system and group. Channel selection is

transparent to the user and is controlled via digital communi-

cation with the system controller. This provides advanced

programmable features and fast access to communication

channels.

In the conventional mode, the user selects a channel and

communicates directly on that channel. A system refers

to a set of channels. A channel is a transmit /receive radio

frequency pair.

The exact operation of the radio will depend on the operating

mode, the radio programming and the particular radio system.

Most features described in this manual may be enabled or

disabled through programming. Consult the system administra-

tor for the particular features that are programmed into the

radio.

This manual provides instructions for operating in either of the

three systems (EDACS, GE-MARC, conventional). A separate

section is provided for each system with a complete set of

instructions for operating the radio within that system.
