Inserting the Dolphin Battery Pack

Place the Dolphin battery pack in the Battery Charging Pocket (see page 11-2) of the Dolphin MultiCharger. 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 Status LED for

that particular pocket lights orange.

Charging Batteries in the Dolphin MultiCharger

The Dolphin MultiCharger is designed to charge a NiMH rechargeable battery pack. Each charging pocket charges one battery

and contains three LEDs to indicate charging status; see Charging Status LEDs on page 11-2.

When a battery is inserted into a charging pocket of the Dolphin MultiCharger, 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 MultiCharger senses that the battery pack is fully charged, the charging rate drops to a trickle charge and the

green status LED lights. 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 Charging Status LEDs (see page 11-2) on each charging pocket indicate the current charging status of the Dolphin battery

pack inserted in that pocket. The following chart shows a summary of each charging state.

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.

Do not attempt to recharge a battery pack that is not manufactured by

Hand Held Products

especially for this device.

To do so will void your warranty can damage the Dolphin MultiCharger.

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

records battery conditions during a charge and discharge cycle and stores these values in the battery pack. These stored values

are then 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.

1. Insert all the batteries that require servicing into the charging pockets and press the yellow Condition and Calibrate Switch

(see page 11-2).

2. The Condition and Calibrate LED (see page 11-2) flashes red to indicate that the cycle has begun.

3. The Dolphin MultiCharger begins to totally discharge and fully recharge the battery pack, automatically. This cycle requires

approximately 8 hours to complete.

4. In each charging pocket, the orange Status LED will begin to flash in sync with the Condition and Calibrate LED.

Any batteries inserted after the Condition and Calibrate switch has been depressed will receive a standard charge.

5. A complete cycle is indicated by a green Status LED.

Because the Dolphin MultiCharger is accumulating battery pack information during the entire Condition and Calibrate cycle,

do NOT remove the battery until the cycle has been completed.

6. Once all batteries have completed the Condition and Calibrate cycle, the Condition and Calibrate LED will turn off.

Status LED When lit, it means …

ORANGE/Charging

The battery is being charged at the maximum charge rate.

GREEN

Battery charging is complete and battery is ready for service. A

trickle charge remains until the battery is removed.

RED/Error

An error was encountered during charging.
