2.1.8. CHARGE INDICATIONS
The following indications are not necessarily a result of a charger problem. They are typically caused by external
problems such as AC line, poor battery conditions, connections, etc. If abnormal charge conditions are detected, the
charge is terminated, the MODE display shows ‘ER’ for error. The DATA display shows the code. Note: The letter
V is displayed as ’U’.
