Primary-cell detection The integrated Primary-cell detection detects if during charging the battery voltage does not exceed the 3.3 V. If high voltage is detected, the handset will stop charging until you take the handset out/in the charger or when the handset reboots due to no power. This is mainly caused by high impedance or wrong type of the batteries (Non-rechargeable, Low quality, old or damaged batteries) Charge debouncer The charging debouncer avoids: - The handset restarts charging when the "table is bounced"
- Handset is in charger and ringing, user takes handset out of charger to answer call and short out/in charger is detected that ends the call
The handset must be removed for 1 second from charger to recognize out-of-charger event. shorter out-of-charger events are suppressed. |
