Power is fed through the RS-232 communications port.

Batteries

CAUTION: Use only the 3.6V battery packs provided by HHP. The use of any other
battery pack in the Dolphin 7400 terminal will void your warranty and may result in
damage to the Dolphin terminal or battery.
There are two batteries in the Dolphin:
Internal NiMH Backup Battery
up the RAM and clock when the NiMH main battery is discharged or removed
from the terminal. The internal backup battery is not user replaceable.
NiMH Battery Pack
the Dolphin terminal.

Internal NiHM Backup Battery

The Dolphin's internal backup battery prevents the terminal from being reset if you
need to remove and replace the main battery pack. The battery retains RAM data
and allows the real-time clock to remain operational for up to 30 minutes when the
battery pack is removed. 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 backup battery is required.
If the backup battery becomes discharged of power after the initial charge cycle, it
will require a minimum of 5 hours of charging time to perform and maintain the
system as described above.
The internal backup battery is charged by the Dolphin's main battery pack when
an external power source such as the Dolphin HomeBase, is not available. If the
terminal is left without the main battery pack for more than 30 minutes, the internal
backup battery will need to be recharged.
