1.2 About the SIM Card and Battery
Always turn off your device before installing/replacing the battery and
SIM card. Follow the instructions in the Quick Start Guide to install
a 3G SIM (Subscriber Identity Module) card provided by Cingular
Wireless and to install the battery.
The SIM card contains your phone number, service details, and
phonebook/message memory. Legacy SIM cards will not function with
your device. You should consult with your Cingular representative for a
replacement SIM card. There may be fees for this service.
Your device contains a rechargeable Li-ion polymer battery. This
device is designed to use only manufacturer-specified original batteries
and accessories. Battery performance depends on many factors,
including your wireless service provider’s network configuration, signal
strength, the temperature of the environment in which you operate your
device, the features and/or settings you select and use, items attached
to connecting ports, and your voice, data, and other program usage
patterns.
Battery life estimates (approximations):
• Standby time: up to 200 hours for GSM; 180 ~ 250 hours for
UMTS/HSDPA.
• Talk time (Screen off): 4 ~ 5 hours for GSM; 2 ~ 4 hours for
UMTS/HSDPA.
Warning! To reduce risk of fire or burns:
• Do not attempt to open, disassemble, or service the battery
pack.
• Do not crush, puncture, short external contacts, or dispose of in
fire or water.
• Do not expose to temperatures above 60 o C (140 o F).
• Replace only with the battery pack designated for this product.
• Recycle or dispose of used battery as stipulated by local
regulation.
