Maintaining the Dolphin’s Batteries
CAUTION: Use only the 3.6V battery packs provided by Hand Held Products.
The use of any other battery pack in the Dolphin 7200 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
Located inside the Dolphin, this battery backs up the RAM and clock when the NiMH
main battery is discharged or removed from the terminal.
NiMH Battery Pack
The battery pack is the primary power source for operating the Dolphin.
Internal NiMH 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. If the internal back-up battery becomes discharged of power, it
requires a minimum of 5 hours of charging time in order to perform and maintain the
system as described above.
The internal backup battery is charged by the Dolphin’s main battery pack. If the
terminal is left without the main battery pack for more than 30 minutes, the internal
backup battery needs to be recharged.
Note: Data and programs on Drives C and D remain safe even if the internal backup battery fails.
However, you must reset the real-time clock using the DOS Time and Date function.
Follow these guidelines to maximize the life of the Dolphin’s backup battery:
•
Keep a charged NiMH battery pack in the Dolphin. The internal battery
will prematurely discharge if there is not at least a partially charged battery
in the terminal.
•
Put the Dolphin in the HomeBase when the terminal is not in use.
N O T E
Return the Dolphin to
an authorized service
center when the
internal battery needs
to be replaced.
N O T E
Never insert the
Dolphin into the
HomeBase without the
NiMH main battery pack
inserted.
