FCC Class A Digital Device or Peripheral - Information to User

ÜÜNOTE

This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, can cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case the
user will be required to correct the interference at his own expense.

ÜÜ WARNING

Changes or Modifications not expressly approved by Futurecom Systems Group Inc. could void the
user’s authority to operate the equipment.

ÜÜ WARNING

To satisfy FCC/IC RF exposure requirements for transmitting devices, a minimum separation distance
should be maintained between the antenna of this device and anyone in the vicinity of the radiating
element. The following table shows the minimum distance, as per FCC 1.1310 requirement, for selected
values of CMDUHF Tx power settings and antenna / feed cable assembly gains:

1.0 SAFETY INFORMATION

The following information may or may not be applicable to your product.
In any case, precautions should always be taken when handling any electrical product.

• This manual contains important safety and operating instructions, therefore keep this manual always

on hand!

• Prior to using any product, follow all warning, safety and operating instructions written on the

product and in the user’s manual. All instructions should be saved for reference in the future!

• Always keep product dry, never expose to any kind of moisture.

• Do Not expose product to extreme temperatures- as found near a hot radiator or stove.

• Do Not expose product to open flames, cigarettes, etc.

• Precautions should be taken to avoid objects falling or liquids spilling onto product.

• Do Not incorporate the use of other equipment that is not recommended or sold by the

manufacturer. The result may be the risk of fire or electric shock injury.

• Connect DC power cord to DC power source as marked on the product..

• DANGER - Never alter the AC cord or plug! If plug does not fit outlet have a qualified electrician

install a proper outlet. Failure to do so results in improper connection and increases the risk of
electric shock.

• This product does not contain customer serviceable components, therefore never disassemble the

product.

• Damage Requiring Service - This product should be serviced by qualified service personnel when:

A. The power supply cord or the plug has been damaged; or
B. Objects have fallen, or liquid has been spilled into the product; or
C. The product has been exposed to rain or moisture; or
D. The product does not appear to operate normally or exhibits a marked change of
performance; or
E. The product has been dropped, or the cabinet damaged.

• If an outdoor antenna is connected, make sure the system is always grounded to allow for

protection against voltage surge and built-up static charges. Outdoor antennas should always be
located away from power lines.

8M074X01-01 Rev.1

The operator of any mobile radio should be aware of certain hazards common to the operation

of vehicular radio transmissions.

A list of possible hazards follows:

1. Explosive Atmospheres

To ensure safety, make sure that the radio is off while fueling the vehicle. When the radio is
mounted in the back of the trunk, never have containers of fuel in the trunk of the vehicle..

2. Interference to Vehicular Electronics Systems

Typical types of electronic devices that malfunction are -Electronic fuel injection systems, electronic
anti-skid braking systems, etc., The reason for this is due to the lack of protection from radio fre­quency energy present when transmitting. If the vehicle contains such equipment, consult the dealer
of your vehicle and enlist his aid in determining if such electronic circuits perform normally when the
radio is transmitting.

3. Dynamite Blasting Caps

Dynamite blasting caps may be caused to explode by operating a radio within 500 feet of the
blasting caps. Always obey the "Turn Off Two Way Radios" 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.

4. Radio Frequency Energy

Do not operate the transmitter when a person is outside of the vehicle within two feet of the
antenna! Failure to heed this warning may result in burns or related physical injury to the person.

5. Liquefied (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 requiring 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.

2.0 GENERAL RADIO OPERATING PROCEDURES

Industry Canada (IC) and the Federal Communications Commission (FCC). rules and regulations
must be incorporated in the use of radio systems. Familiarity with these rules by the operator is essential
for proper execution of the type of radio operation that is in question. Following these rules helps to
eliminate confusion, assures the most efficient use of existing radio channels, and results in a smoothly
functioning radio network. When using this unit remember these rules:

1. Emergency calls always have priority over all messages! To interrupt any distress or emergency

message is a violation of the IC and FCC rules. When operating the radio make sure that the line is

clear before sending messages. KEEP OFF THE AIR when an emergency message is being sent

through.

2. Use of profane or obscene language is prohibited by Federal law.

3. Sending false call letters, false distress or emergency messages is against the law.

4. IC and FCC demand that conversations are kept brief and content limited only to business. Coded

messages are encouraged in order to save time.

5. Only messages that are essential for the business operations are allowed to be sent. Otherwise

using the radio to send personal messages is a direct violation of the IC and FCC rules.

6. Conversations between others sharing a channel is regarded as confidential. Repeating anything

overheard on the radio is against Federal Law.

7. The IC and FCC requires the operator to transmit station identification at certain times by means of

call letters. Refer to the IC and FCC rules for your station's particular type of operation for the

proper procedure.

8. No changes or adjustments shall be made to the equipment except by an authorized or certified

electronics technician.
