On backup
The built-in lithium battery enables retention of the memories such as preset
camera adjustments even if the Communication Terminal is turned off.
Notes
• The built-in lithium battery is kept charged as long as the system is operated. If the
system is not used for a long time, the battery is gradually discharged. It will be
completely discharged when you do not use the system for 12 weeks. To retain the
system's memory, recharge the battery.
• To recharge the battery, connect the camera to the Communication Terminal and
leave both units with the power on for about 48 hours.
