• Do not paint the phone. Paint can clog the device's
moving parts and prevent proper operation.
• Do not touch the terminals on the battery or charger
with wet hands. Doing so may give you an electronic
shock or cause explosion. Touching the plug of the
charger with wet hands may give you an electronic
shock or cause a fire.
• Use only the supplied or an approved replacement
antenna. Unauthorized antennas or modified
accessories may damage the phone and violate
regulations governing radio devices.
• If the phone, battery, charger or any accessory is not
working properly, take it to your nearest qualified
service facility. The personnel there will assist you,
and if necessary, arrange for service.

Glossary
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.
DTMF - (Dual-Tone Multi-Frequency ) You send DTMF
signals when you enter numbers by pressing the digit
keys.
