Charging Batteries In The QuadCharger
Follow these steps to charge batteries in the QuadCharger:
1. Set up the charger for use
2. Supply power
3. Insert batteries
CAUTION: Do not attempt to recharge any battery pack in the Dolphin 7400/7450 QuadCharger that is not manufactured
by HHP especially for this device. To do so will void your warranty and could damage the Dolphin 7400/7450
QuadCharger.
Setting Up The QuadCharger
The Dolphin QuadCharger should be set up on any dry, stable surface. DIN rail slots on the bottom panel allow the charger to
be wall or desktop-mounted for easily adapting the unit to your environment.
The charger must be connected to a power source for any type of operation.
Supplying Power To The QuadCharger
CAUTION: Using a non-HHP power cord voids your warranty and could result in serious damage to the Dolphin
QuadCharger’s circuitry.
Locate the AC power cord that came with the Dolphin QuadCharger. Plug the cord into the power supply connector on the back
of the unit and then plug the power cord into a wall socket.
Press and hold the Power Switch for approximately one second, then release, to turn on the Dolphin 7400 QuadCharger. The
GREEN power LED will illuminate and the charger will undergo a self-diagnostic test.
Inserting and Removing Battery Packs
To insert a battery pack, place the end of the battery without the locking tab into the bottom of the charging pocket and snap the
battery into place with a hinging motion. Once the battery is properly seated, the orange status LED for that particular pocket will
illuminate.
For best results, battery packs should be at room temperature before recharging them; temperature has a marked effect on
charging. The recommended temperature range is 50° to 95° F (10° to 35° C).
