3 Charge the battery pack independently.
Make sure that the back of the battery pack (the side with the
label) is facing towards you. Align the battery with the desktop
holder and insert the battery pack all the way to the end until it
is locked. Be sure to position the plug with the SONY logo side
facing up when connecting.

Charging indicator on the battery pack
A red light comes on when charging starts. The light turns green,
after about 3 hours, when charging is complete. But, it may vary
depending on certain conditions e.g. If your phone is switched on or
temperature is beyond operational range. As an energy saving
measure, disconnect the AC adaptor from the mains socket and from
the phone after charging.
The battery icon on the display indicates charging status. When the
battery is almost completely charged, the battery icon shows all bars.
However, this display shows an approximate indication only, check the
indicator on the battery pack (refer to the above) to confirm whether or not
the battery pack is fully charged.
Important
• If the red light on the battery pack blinks, reconnect the AC adaptor and reinsert
the phone (or the battery pack). If you repeat this process several times and the
indicator continues blinking, the battery pack might be defective. Stop charging
the battery pack immediately and replace it.
• Use only the Sony-specified CMD-MZ5 battery pack and charger. Your battery is
equipped with short circuit protection. If you short your battery accidentally,
charge the battery immediately to unlock the short circuit protection.
Usage time
When your battery pack is nearly discharged the battery icon on the
display blinks and the phone beeps to inform you that only a short
amount of calling time remains.
