WIRELESS EMERGENCY CALL DEVICE |
摘要 |
A portable emergency call device has a single activation button to establish two way communications with an emergency call center. It is not a standard telephone and does not receive any incoming calls and can place outgoing calls only to the designated emergency call center. There is an advantage to making it waterproof.
