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
Located inside the Dolphin, this battery backs 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 battery pack is the primary power source for operating 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
IntelliBase, 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.
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 Pocket PC 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 IntelliBase 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 HHP 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 7400/7450 terminal may be stored in RAM, so it is important 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 top 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 the terminal to lose all data in RAM. 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.
If the main battery is low and the terminal is in sleep mode, pressing the ON/SCAN button or the scan trigger will not wake up
the Dolphin 7400/7450 terminal; you must replace the discharged battery with a fully charged battery.
