Safety Information
• Do not attempt to open the phone. Non-expert
handling of the phone may damage it.
• Do not drop or knock the phone. Rough handling may
damage the internal circuits.
• 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
center. 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 transmitted
signal is just above noise level across the
available bandwidth.
Channel
- Communications signals transmit along paths
called channels.
Codec
- Compression & Decompression.
Deactivation
- The process of rendering a wireless
phone inactive.
