About your phone
• IMPORTANT BATTERY INFORMATION
Use the following guidelines to obtain the best performance from your battery:
•
With your phone turned off, charge your new battery for three hours before its first use.
Use the battery until it is fully discharged. Repeat this procedure twice for a total of
three charging cycles.
•
Battery operation time may be less than the estimated times during the first charges.
This condition is normal.
•
If the battery is fully discharged, the scrolling bars may not appear immediately
when charging.
•
After the first charge, you can make and receive calls during the charging cycle, but the
calls interrupt the charge. When the phone call ends, the charge will resume.
•
The bars on the screen stop scrolling and remain constant when the phone is charged. If
you leave the phone connected to the charger, the battery receives an additional charge.
Note: The battery will accept a “trickle charge” for an additional two hours. See
“Reference Information” on page 47 for more information on batteries.
•
Charging time depends on the charger and battery used. See “Hardware and accessories”
on page 45 for charging, talk, and standby times.
• PROLONG BATTERY LIFE
For good operation times with NiMH batteries, discharge the battery from time to time by
leaving your phone switched on until it turns itself off. Ignore any messages to recharge your
battery and let the battery completely discharge.
Note: Do not attempt to discharge the battery by any other means.
• HEADSET
Your phone is compatible with the HDC-5, HDE-2 and HDB-5 headsets.
To connect the headset:
1
Plug the headset jack into the bottom of your phone.
2
Put the earbud into one ear.
With the headset connected, you can make and answer calls as usual.
The microphone for the headset hangs at the side of your head. Although the microphone may
seem far from your mouth, you can speak at a normal volume.
Note: You can set your phone to answer automatically when the headset is
connected. See “Automatic answer” on page 26.
