American Diagnostic Corporation (ADC) Diagnostix Desk Charging Base - Manual (Page 4)

c) Charging Time
The end of the charging time is detected by evaluation of the negative voltage •
differential caused by heating of the rechargeable battery cells when fully
charged. The yellow charging LED will switch off and the green ”rechargeable
battery full” LED will switch on.
The charging time is limited to max. 4.75 h by the internal timer.
•
When the rechargeable battery is fully charged •
(green LED on), the unit will switch to
maintenance charge.
The temperature inside the charger base is
•
monitored. Do not keep in sunlight, or close
proximity of a radiator, as over heating may cause
premature actuation of the automatic switch-off
mechanism shutting the charger off before
completing a full charge.
Warning!
When the handle is removed from the charging chamber for a few seconds •
whilst the rechargeable battery is fully charged (green LED on) without
switching on, initially the yellow charging LED will be switched on when
reinserting the unused rechargeable battery. However, this is not due to
malfunction of the charging base but the described ”rechargeable battery full”
sensor.
When the rechargeable battery is full, no negative voltage differential can be
•
recorded. The rechargeable battery must first heat up in order to signal
”rechargeable battery fully charged”.
The time prior to the green ”rechargeable battery fully charged” LED switching
•
on again may vary considerably (15 minutes or longer). Additional temperature
sensing and a timer, however, ensure that the charging process is carefully
monitored at any time.
We recommend to keep the instrument in the charging chambers after
use to ensure that instruments are always ready.
5. SPECULA COMPARTMENT
The specula compartment may be used for spare
specula and lamps.
