V660 Quick Start Guide
3.1 Installing the Battery and a SIM Card
This section describes how to install the battery that came 
with your V660, and how to install a SIM (Subscriber Identity 
Module) card. A SIM card allows you to make and receive 
cellphone calls with the V660. If you do not want to install a 
SIM card now, you can still use the V660’s other features 
once the battery is installed.
"Fully charge the battery before you first use the 
V660. This may take 8 to 10 hours. When you 
first charge the battery, use the included charger 
and NOT the USB cable. The power supplied 
from a computer’s USB port is not enough to 
fully charge the battery. Use the charger instead 
of the USB cable whenever possible. 
1Remove the V660’s battery cover. Press the grooved area 
at the top of the cover, slide the cover downwards 
(towards the V660’s base) and lift it off.
2Install a SIM (Subscriber Identity Module) card. If you do 
not want to install a SIM card now, skip to step 3.
