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 com-
munications, for example emergency 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.
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 pro-
tection circuit should be implemented in the cellular application.
