CONFIDENTIAL 1 (1) Nokia Mobile Phones Service Bulletin No. SB-019/30.03.01 Technical Support, Europe & Africa NHM-3 IMPROVEMENT ON CARKIT DETECTION In some cases the phone has not started charging, when placing the phone in power off -state to Active Car Holder (MCC-2). Only phones with layout version SM4_15 can suffer from this occasional insufficient detection. Following change can improve the detection and it has been implemented in production since serial number 350001/15/105600/3: Assemble resistor R260 to the place of unassembled capacitor C260 (see picture below) When phone is in Power On -state, resistor R260 is shorted by transistor V221, but when phone is in Power Off -state, carkit detection is made by pulling down SGND-line with resistor R260.
