5.2. Vibration issue:
The vibrator circuit is simple, one point connected toVIBR and the other to GND. VIBR
voltage is approximately equal to battery voltage, and VIBR voltage outputs from the core chip
and is controlled by the software. When vibration enabled, the differential voltage of the vibrator
is close to 3.0 v, when vibration disabled, the differential voltage is close to 0 v.

Repair steps:
1. Check whether the Vibrator is damaged and the soldering is well or not;
2. Check if the related circuits, ,have soldering issues, etc;
3. Replace with new Vibrator, and verify again;
4. Enable and disable vibration functions respectively, check whether both ends of the Vibrator
voltage are normal or not. If abnormal, check if the U0100 has soldering or performance problems.
