Prepare the battery pack
Insert the battery into the handset and charge first before you start using your phone.
1
Slide open the battery compartment lid of the handset.
2
Connect the battery connector with correct polarity (black wire goes on
lower side and red wire goes on upper side).
3
Insert the battery pack, and close the lid.
4
Place the handset on the base unit.
The LINE/CHARGE lamp lights up when the handset is properly seated
on the charge terminals of the base unit. Charge the battery pack for
more than
12 hours
so that the battery is fully charged. The LINE/
CHARGE lamp remains lit even after charging is completed.
Battery duration
A fully charged battery pack lasts for about:
• 10 hours when you use the handset continuously.
• 30 days when the handset is in standing by.
Notes
• The battery pack will gradually discharge over a long period of time, even if not in use.
• If you leave the battery pack in the handset without charging it, the battery pack will be
completely discharged. It may require several times of charging to recover to its full capacity.
• If the battery runs out completely, the setting of dialing mode, the speed dial numbers and the
digital security code will be erased. If this happens, charge it on the base unit for over 12 hours.
Then choose the dialing mode, set the ringer type, reprogram the speed dial numbers, and
assign a new digital security code (see “Resetting the digital security code”). You may need to
charge the battery several times before it is recharged to its full capacity.
To obtain the best performance from battery
Do not place the handset on the base unit after each call. The battery works best if the
handset is returned to the base unit after two or three calls. However, do not leave the
handset off the base unit for a long period of time as this will completely discharge
the battery pack.
When to purchase a new battery pack
If the battery lasts only a few minutes even after
12 hours
of charging, the usable
life of the battery has expired and needs replacement. Contact your local Sony
authorized dealer or service center, and ask for Sony
BP-T50
rechargeable battery
pack.
Note
Battery life may vary depending on usage condition and ambient temperature.
Choose the dialing mode
For the telephone to work properly, select an appropriate dialing mode (tone or
pulse). The default setting is tone.
Note
Do not allow more than 20 seconds to elapse between each step of the procedure.
