IMPORTANT!

Cellular terminals or mobiles operate using radio signals and cellular networks. Because of

this, connection cannot be guaranteed at all times under all conditions. Therefore, you should

never rely solely upon any wireless device for essential communications, for example emer-

gency calls.

Remember, in order to make or receive calls, the cellular terminal or mobile must be switched

on and in a service area with adequate cellular signal strength.

Some networks do not allow for emergency calls if certain network services or phone features

are in use (e.g. lock functions, fixed dialing etc.). You may need to deactivate those features

before you can make an emergency call.

Some networks require that a valid SIM card be properly inserted in the cellular terminal or

mobile.

Bear in mind that exposure to excessive levels of noise can cause physical damage to users!

With regard to acoustic shock, the cellular application must be designed to avoid unintentional

increase of amplification, e.g. for a highly sensitive earpiece. A protection circuit should be

implemented in the cellular application.
