On the first page of the system menu, push the button "SAFETY OPTION".
Another setting menu appears.
Safety timer ("TIME" button)
If charging starts, the internal safety timer starts as well. If the charger cannot detect whether
the battery is fully charged for whatever reason (e.g. with delta-U detection), the charge
process is terminated automatically after a set time if the safety timer is on. This protects the
battery from overloading. The safety timer can be switched on ("ON") or off ("OFF"); the time
for the safety timer can also be changed.
Do not set the time too short, since the rechargeable battery cannot be fully charged
then because the safety timer will cancel charging.
Calculate the time for the safety timer as follows (examples):
Battery capacity
2000 mAh
3300 mAh
1000 mAh
The factor 11.9 is used to permit charging 140% of the rechargeable battery capacity
(the rechargeable battery is guaranteed to be fully charged then), before the safety timer
trips.
Charging current
2.0 A
3.0 A
1.2 A
Timer time
2000 / 2.0 = 1000 / 11.9 = 84 minutes
3300 / 3.0 = 1100 / 11.9 = 92 minutes
1000 / 1.2 = 833 / 11.9 = 70 minutes
