Safety Information
• Do not use harsh chemicals, cleaning solvents or strong
detergents to clean the phone. Wipe it with a soft cloth
slightly dampened in mild, soapy water.
• If the phone or any of its accessories are not working
properly, take them to your nearest qualified service centre.
The personnel there will assist you, and if necessary,
arrange for the phone to be repaired.
Emergency Calls
Important! This phone, like any cellular phone, uses radio
signals, cellular and landline networks, as well
as user-programmed functions that cannot
guarantee connection in all conditions.
Therefore, you should never rely solely on any
cellular phone for essential communications
(medical emergencies for example).
Remember, to make or receive any calls, the phone must be
switched on and in a service area with adequate cellular
signal strength.
Emergency calls may not be possible on all cellular phone
networks or when certain network services and/or phone
features are in use. Check with local cellular service
providers.
Glossary of Terms
Airtime - Actual time spent talking on the wireless phone.
Most carriers bill customers based on how many
minutes of airtime they use each month.
Antenna - A device for transmitting or receiving signals. The
size and shape of antennas is determined, in part,
by the frequency of the signal they receive.
Wireless phones and the base station must have
antennas.
Base Station - The fixed radio transmitter/receiver that
maintains communications with mobile radio
telephones within a given area. (Typically
called a cell or cell site)
CDMA - (Code Division Multiple Access) A spread-spectrum
approach to digital transmission. With CDMA, each
conversion is digitized and then tagged with a code.
The mobile phone deciphers only a particular code to
pick the right conversation off the air. The transmit-
ted signal is just above noise level across the avail-
able bandwidth.
Channel - Communications signals transmit along paths
called channels.
Codec - Compression & Decompression.
Deactivation - The process of rendering a wireless phone
inactive.
DTMF - (Dual-tone Modulated Frequency ) You send DTMF
signals when you enter numbers by pressing the digit
keys.
