O PERATING I NSTRUCTIONS
Electronic instruments are delicate, operate the batter charger with
care.
The 491198-36 battery charger is intended to charge the 3.6 volt NiCd batteries,
either in the lab or in the field.
After connecting the battery charger to a proper power source, the battery
charger simply plugs into the charger jack on the HI-4416. The HI-4416 must be
turned off or the battery will not charge.
C HARGING I NDICATORS
There are five LEDs located on the front of the charger that provide operating
information to the user.
 The POWER ON LED (green) will remain illuminated as long as the
charger is plugged into the AC power source.
 If the charger does not detect a battery, the NO BATTERY LED
(amber) light will illuminate.
 When the charger does detect the unit’s battery, the PENDING LED
(amber) light illuminates while the charger qualifies the battery for fast
charge. If the voltage is below the safe fast charge level, the battery is
charged in the pulse trickle mode.
 When the voltage is at a safe level the charger will switch to the fast
charge mode and the CHARGING LED (amber) light illuminates.
 When charging is complete, the charger switches back to the pulse
trickle mode and the COMPLETE LED (green) light will illuminate. The
device can be left on the charger in this maintenance mode indefinitely.
