Emergency Calls This mobile device, like any wireless mobile device, operates using radio signals, wireless and landline networks, as well as userprogrammed functions, which cannot guarantee connection in all conditions, areas, or circumstances. Therefore, you should never rely solely on any wireless mobile device for essential communications (medical emergencies, for example). Before traveling in remote or underdeveloped areas, plan an alternate method of contacting emergency services personnel. Remember, to make or receive any calls, the mobile device must be switched on and in a service area with adequate signal strength. Emergency calls may not be possible on all wireless mobile device networks or when certain network services and/or mobile device features are in use. Check with local service providers. To make an emergency call: 1. If the mobile device is not on, switch it on. 2. Key in the emergency number for your present location (for example, 911 or other official emergency number). Emergency numbers vary by location. 3. Press the "Send" key ( ). If certain features are in use (call blocking, for example), you may first need to deactivate those features before you can make an emergency call.
