Emergency calls
Important: Wireless phones, including this device,
operate using radio signals, wireless networks, landline
networks, and user-programmed functions. Because of
this, connections in all conditions cannot be
guaranteed. You should never rely solely on any wireless
device for essential communications like medical
emergencies.
To make an emergency call:
1. If the device is not on, switch it on. Check for adequate signal
strength.
Some networks may require that a valid SIM card is properly
inserted in the device.
2. Press the end key as many times as needed to clear the display
and ready the device for calls.
