Asus P535 - Manual (Page 16)

Installing the SIM card and battery
Before you can make a phone call using your P535, you need to install a Subscriber Identity
Module (SIM) card. A SIM card contains your phone number, subscriber details, phonebook,
and additional phone memory.
Your P535 comes with a rechargeable Lithium-Ion battery.
New batteries come partially discharged and should be fully charged before using them. They
generally do not reach their rated capacity until they have been charged and discharged at
least four (4) times. We recommend that new batteries be charged overnight even though
they may indicate that the charge is complete after a few hours. Sometimes charging may
stop during the initial charge and it is necessary to remove the battery for approximately
fifteen (15) minutes and then put it back on charge.
Getting your device ready
1. Remove the battery compartment cover.
NOTE:
When turned on, the device automatically turns off
after you open the battery compartment to prevent
data loss.
CAUTION:
Use only an ASUS qualified battery.
