WARNING
will void your warranty and may result in damage to the Dolphin terminal or battery.
Although the Dolphin 7400/7450 terminal is received with the battery inserted, it is NOT ready for charging and/or
WARNING
deep-cycling. Remove the plastic insulator located between the terminal and battery connectors. Failure to remove the insulator
may result in damages to the terminal.
The terminal's NiMH battery is not conditioned at the factory and is shipped discharged of all power and inserted in the Dolphin
terminal.
For maximum battery life, HHP recommends that you deep-cycle the battery twice before initial use. It is also recommended that
you service the battery once per month. Refer to the section on Managing Battery Power in Chapter 3 for further information on
deep-cycling the battery.
After deep-cycling the battery, the terminal's NiMH battery must be charged before using it for the first time. To charge the main
battery pack:
1. Place the main battery pack in the Dolphin 7400/7450 terminal.
2. Place the terminal in the terminal well of the Dolphin HomeBase. Time to Charge: 3.5 hours for the main battery; 8 hours for
the back-up battery
As the main battery pack charges, the internal back-up battery also charges. For the initial charging cycle, it is recommended
that the terminal be charged for approximately 8 hours to allow adequate charging time for the back-up battery. Not doing so may
result in the terminal becoming unstable should the unit lose power and the back-up battery is required. The back-up battery
maintains the RAM and clock when the NiMH main battery pack is discharged or removed from the terminal.
