Introduction
The Dolphin Multiple Battery Charger provides intelligent battery management for 10 Dolphin battery packs.
Intelligent Battery Charging
The battery charging circuitry is intelligent and can sense changes in temperature and voltage. The Dolphin Multiple
Battery Charger charges the battery rapidly, when the Dolphin Multiple Battery Charger senses that the battery pack
is fully charged, the charging rate drops to a trickle charge. The trickle charge keeps the battery pack at full
capacity. This charging method protects the battery from being damaged by overcharging. The Dolphin Multiple
Battery Charger can charge 10 battery pack simultaneously with individual charge control circuitry for each of the 10
battery pocket locations.

Getting Started
Setting Up The Dolphin Multiple Battery Charger
The Dolphin Multiple Battery Charger should be setup on any dry, stable surface.
You must connect the Dolphin Multiple Battery Charger to a power source for any type of operation.
HHP recommends that you leave the Dolphin Multiple Battery Charger connected to its power source at all times, so
that it is always ready to use.
Supplying Power To The Dolphin Multiple Battery Charger
Locate the AC power cord that came with your Dolphin Multiple Battery Charger. Plug the power cord into the
Dolphin Multiple Battery Charger Universal wide input voltage AC input, then plug the power cord into a wall
socket.
Depress the GREEN Power Switch located in the bottom left-hand corner of the top panel. The GREEN power LED
will illuminate and the charger will undergo a self diagnostic test.
CAUTION:Using a non-HHP power cord will void your warranty and can result in serious damage to the Dolphin
Multiple Battery Charger circuitry.

Dolphin Multiple Battery Charger User’s Guide Page 3
Inserting The Dolphin Battery Pack Into The Charger
Place the Dolphin Battery Pack in the charging pocket of the Dolphin Multiple Battery Charger. Let the Dolphin
Battery Pack glide down into the charging pocket until it stops. Asserting a downward and forward motion, apply
enough pressure to latch the Dolphin Battery Pack in the charging pocket. Once the Dolphin Battery Pack is properly
seated, the orange status LED for that particular pocket will illuminate.
Charging Batteries In The Dolphin Multiple Battery Charger
The Dolphin Multiple Battery Charger is designed to charge a NiMH rechargeable battery pack.
When a battery is inserted into the Dolphin Multiple Battery Charger, the unit will start charging the battery at the
highest rate possible. This state is indicated by a steady orange status LED.
When the Dolphin Multiple Battery Charger senses that the battery pack is fully charged, the charging rate drops to a
trickle charge and the GREEN status LED illuminates. The trickle charge keeps the battery pack at full capacity. A
dead battery will charge to full capacity in approximately three hours. This charging method protects the battery
from being damaged by overcharging.
The Dolphin Multiple Battery Charger’s status LEDs indicate the current charging status of the Dolphin Battery
Pack. The following chart shows a summary of each charging state.
Status LED’s Meaning
ORANGE Battery is being charged at maximum
charge rate.
GREEN Battery charging is complete and battery
is ready for service. Battery remains in
trickle charge until removed.
RED Error was encountered during charging.

Battery Temperatures
If possible, bring your rechargeable NiMH battery packs to room temperature before recharging them; temperature
has a marked effect on charging. The recommended temperature range is 10°to 35°C.
Caution: Do not attempt to recharge any battery pack in the Dolphin Multiple Battery Charger that is not
manufactured by HHP especially for this device. To do so will void your warranty can damage the Dolphin Multiple
Battery Charger.

Dolphin Multiple Battery Charger User’s Guide Page 4
Servicing The Battery Pack
The Condition and Calibrate cycle is used to update the Battery Pack Data Record stored in the Dolphin Battery
Pack. This cycle will record battery conditions during a charge and discharge cycle and store these values in the
battery pack. These values will be used to minimize errors associated with rechargeable batteries such as battery
wear out, voltage depression, and self discharge. As a general rule, battery packs should be calibrated once a month.
To service the battery packs, simply insert all the batteries that require servicing into the charging pockets and press
the yellow "Condition and Calibrate" button located below the POWER button on the Dolphin Multiple Battery
Charger.
The Dolphin Multiple Battery Charger will then totally discharge and fully recharge the battery pack, automatically.
This cycle requires approximately 8 hours to complete. The ORANGE status LED will begin to flash in sync with
the LED associated with the “Condition and Calibrate” switch. Any batteries inserted after the “Condition and
Calibrate” switch has been depressed will receive a standard charge.
Because the Dolphin Multiple Battery Charger is accumulating battery pack information during the entire “Condition
and Calibrate” cycle, it is important not to remove the battery until the cycle has been completed. A complete cycle
is indicated by a GREEN status LED. Once all batteries have completed the “Condition and Calibrate” cycle, the
FLASHING LED associated with the “Condition and Calibrate” switch will turn off. At this point, if desired, another
“Condition and Calibrate” cycle can be initiated.

Troubleshooting
If you encounter problems with your Dolphin Multiple Battery Charger, first, please go through the list of problems
and solutions in this chapter. If problem persist, please contact Hand Held Products Technical Support.
Problem Issue
The ‘CHARGING” LED does
not come on when I insert a
battery pack into the Dolphin
Multiple Battery Charger
Check the power connections
on the Dolphin Multiple
Battery Charger. Also check to
ensure the POWER switch is
ON and the battery pack is
properly seated.
The RED status “ERROR”
LED comes ON during
charging.
Attempt to charge the battery in
another pocket location. If the
RED “ERROR” LED follows
the battery, then the problem is
associated with the battery
pack. If the RED “ERROR”
LED stays with the pocket then
the problem is associated with
the charging circuitry.
The RED “ERROR” LED
remains ON, without a battery
in the charging pocket.
An error occurred during the
self diagnostic test for that
particular pocket location.
Refer problem to Hand Held
Products Technical Support.
