3. Press PTT to save the code setting.

You can set a different code for each channel using this procedure.

Note: You must set the Interference Eliminator Code to 0 on an FRS radio

that uses Interference Eliminator Codes to communicate with other FRS

radios that do not have Interference Eliminator Codes.

To prevent accidental transmissions and save battery life, the radio emits a

continuous warning tone and stops transmitting if you press PTT for 180

continuous seconds.

Important Information on Safe and Efficient Operation

Read This Information Before Using Your Radio

The information pro\ ided in this document supersedes the general safety

information contained m user guides published prior to July 2000.

Transmit and Receive Procedure

Your rvvo-w a\ radio contains a transmitter and a receiver. To control your

exposure and ensure compliance with the general population/uncontrolled

en\ ironment exposure limits, always adhere to the following procedure:

01

DOWN to select the LO OR III level

• Transmit no more than 50% of the time.

• To transmit < talk). press the Push to Talk (P IT) button.

• To receive calls, release the PTT button.

Transmitting 50% of the time, or less, is important because the radio

generates measurable RF energy exposure only when transmitting (in terms

of measuring standards compliance).

Your radio is designed to comply with the following national and

international standards and guidelines regarding exposure of human beings

Page 8

to radio frequency electromagnetic energy

7 uy>- H V/)'

W

hen using \ our radio as a traditional two-way radio, hold the radio in

a vertical position with the microphone one to two inches (2.5 to

5 cm) away from the lips

To avoid electromagnetic interference and/or compatibility conflicts, turn

off your radio in any facility w here posted notices instruct you to do so.

Hospitals or health care facilities may be using equipment that is sensitive

to external RF energy

Radio Operation

02SK3

When instructed to do so, turn off your radio when on board an aircraft.

Any use of a radio must be in accordance with applicable regulations per

airline crew instructions.

Turn off your radio prior to entering any area with a potentially explosive

atmosphere. Do not remove, install, or charge batteries in such areas. Sparks

in a potentially explosive atmosphere can cause an explosion or lire

resulting in bodily injury' or even death.

Note: The areas with potentially explosive atmospheres referred to above

include fueling areas such as below decks 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 would normally be advised to turn off your vehicle engine. Areas w ith

potentially explosive atmospheres are often but not always posted

Page 9

To avoid possible interference with blasting operations, turn off your radio

when > ou are near electrical blasting caps, in a blasting area, or in areas

posted "Turn off tw o-way radio." Obey all signs and instructions.

Do not use any portable radio that lias a damaged antenna.

II a damaged antenna comes into contact with your skin, a minor burn can

result.

All batteries can cause property damage and/or bodily injury such as burns

if a conductive material such as jewelry, keys, or beaded chains touch

exposed terminals.

The conductive 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

1. Do not expose the charger to rain or snow.

2. Do not operate or disassemble the charger if it has received a sharp blow,

or has been dropped or damaged in any way.

3. Never alter the AC cord or plug provided with the unit. If the plug w ill

not fit the outlet, have the proper outlet installed by a qualified electrician

Page 10

\n improper condition can result in a risk ol electric shock

4 fo reduce the risk of damage to the cord 01 plug, pull the plug rather than

the cord when disconnecting the chargci from tlie AC receptacle

5 To reduce the risk of electric shock, unplug the charger from the outlet

before attempting an> maintenance or cleaning

6 Use of an attachment, not recommended, ma\ result in a risk of fire,

electric shock, or personal injur)

7 Make sure the cord is located where it will not be stepped on, tripped

over, or subjected to damage oi stress

8 An extension cord should not be used unless absolutely necessary. Use of

an improper extension cord could result in a risk of lire and/or electric

shock If an extension cord must be used, make sure that:

• The pins on the plug of the extension cord are the same number, size, and

shape as those on the plug of the charger.

• The extension cord is properly wired and in good electrical condition.

• The cord size is 18 AWG for lengths up to 100 feet, and 16 AWG for

lengths up to 150 feet.
