Antenna
The VX9900 has internal Antenna.
!!! Unauthorized antennas, modifications, or attachments could damage the phone and
may violate FCC regulations.
For your phone to operate most efficiently:
Do not touch the antenna unnecessarily when the phone is in use. Contact with the antenna affects call quality
and may cause the phone to operate at a higher power level than otherwise needed.
Signal Strength
The quality of each call you make or receive depends on the signal strength on your area. The number of
bars in the Signal Strength icon informs you of the current strength. The more bars, the stronger the signal.
Battery Capacity
Your VX9900 is equipped with a Lithium Polymer battery. It allows you to recharge your battery before it
is fully drained. The battery provides approximately 150 minuets of continuous digital talk time or
approximately 110 hours of continuous digital standby time.
Note: Long backlight settings affect the battery’s talk and standby times.
When the battery reaches 5% of its capacity, the battery icon blinks. When there is about one minute of
talk time left, the phone sounds an audible alert every 30 seconds and then powers down.
If the battery’s charge is completely run down, it takes 2 to 3 hours to fully recharge. It is not necessary to
let the battery completely run down before recharging.
To charge your batteries, use only approved charging accessories.
