4 Safety instructions

4.1 General

Please read carefully through the following information concerning safety and proper 
use. Make yourself familiar with all functions of the device. Keep this manual in a safe 
place for future use.

4.2 Burning injuries

• 

If the cover of the antenna is damaged, do not touch because when an antenna 
comes in contact with the skin, a minor burn may result when transmitting.

• 

Batteries can cause property damage such as burns if conductive material such as
jewellery, 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.

4.3 Injuries

• 

Do not place your device in the area over an air bag or in the air bag deployment 
area. Air bags inflate with great force. If a PMR is placed in the bag deployment 
area and the air bag inflates, the communicator may be propelled with great force 
and cause serious injury to the occupants of the vehicle.

• 

Keep the PMR at least 15 centimetres away from a pacemaker.

• 

Turn your PMR OFF as soon as interference is taking place with medical 
equipment.

4.4 Danger of explosion

• 

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

• 

Turn your PMR off when in any area with a potentially explosive atmosphere. 
Sparks in such areas could cause an explosion or fire resulting in bodily injury or 
even death.

• 

Never throw batteries in fire as they may explode.
