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 if

the unit loses 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. 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 stored in FLASH remain safe even if the internal backup

battery fails. However, you must reset the real-time clock using the Windows CE

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.

Main Battery Pack

The 3.6V, 2700 mAh Nickel-Metal-Hydride (NiMH) battery pack is the primary

power source for the Dolphin. Other NiMH batteries may be approved by HHP to

work with your Dolphin. Contact Hand Held for more information.

The 2700 mAh NiMH battery is designed to operate in a 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).

Managing Battery Power

Data and files saved on the Dolphin 7300 terminal may be stored in RAM, so it is

important for you to maintain a continuous power supply to the terminal. When the

main battery pack becomes low, the Low Battery Charge icon will appear in the

notification tray at the bottom of the screen. The Critical icon will appear when the

battery is critically low. There is also a Low Battery icon that will appear when the

back-up battery is low.

Letting the back-up battery become fully discharged will cause you to lose all

data. Therefore, you should 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 charged pack in the Dolphin. The internal battery will prematurely

discharge if there is not at least a partially charged battery in the terminal.

A battery status indicator will display in the notification tray when the battery is low

or critically low. If there is no indicator, the battery is adequately charged.
