6.1.1. Battery
Replacement
Regardless of the indicated charge level, the backup battery must be replaced at
least every five years.
Only use a CR1620 (3V lithium battery) manufactured by SONY
(or an
equivalent manufacturer; deviating charge current is 2.5 mA or more).
The use of any other battery may result in fire or explosion.
The real-time clock’s backup battery can be replaced without the risk of data loss
provided the DIALOG CONTROLLER supply voltage is switched on.
Battery replacement
The battery is held in place by a spring clip. Never lift the spring clip retainer as
this can destroy the clip.
•
Push the old battery out to the side.
•
Insert the new battery from the side.
Check for correct polarity and battery type.
