3 - 8 Dolphin® 7200 User’s Guide
Maintaining the Dolphin's Batteries
Although the Dolphin 7200 terminal is received with the battery inserted, it is NOT ready for charging and/or 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.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:
1. 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.
2. NiMH Battery Pack - Inserted into the back panel, 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.
Guidelines
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.
Note: Return the Dolphin to an authorized service center when the internal battery needs to be replaced.
NiMH Battery Pack
The 3.6V, 1500 mAh Nickel-Metal-Hydride (NiMH) battery pack is the primary power source for the Dolphin. Other Nickel-Metal-
Hydride batteries may be approved by Hand Held Products, Inc. to work with your Dolphin. Contact Hand Held for more
information.
The 1500 mAh NiMH battery is designed to operate in temperature range of -10 to 50 C (14 to 122 F). For maximum performance,
charge the batteries between 10 and 35 C (50 and 95 F).
Although the Dolphin 7200 terminal is received with the battery inserted, it is NOT ready for charging and/or 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.
Performance specifications for a fully charged 1500 mAh NiMH battery (using power management function calls within
application):
• Up to 20 hours of usage in a Dolphin Batch terminal with a full battery charge
• Up to 20 hours of usage in a Dolphin 2D terminal with a full battery charge
Keep a charged battery pack in the Dolphin at all times to conserve the internal back-up battery. When you remove a battery
pack, insert another battery pack in the Dolphin. The internal battery will prematurely discharge if there is not at least a partially
charged battery in the terminal.
