Power
5 VDC Port
This port connects the Dolphin 7400/7450 to DC power for powering peripheral
devices and charging the main and backup batteries.
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 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.
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 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 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 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.
Setting Critical and Low Battery Points
The Dolphin 7400/7450 may be programmed to display warnings when the
battery reaches critical and low battery points. There are two entries defined in the
registry. The specific settings are:
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Power]
35
•
•
•
•
•
•
"CriticalBatt"=dword:a
"LowBatt"=dword:19
"CriticalBatt"=dword:a
This sets the Critical Battery point to 10 percent (a hex = 10 decimal). The critical
battery is the point at which the customer is warned that the battery charge is very
low. This warning will be posted every 3 minutes until the situation is corrected.
"LowBatt"=dword:19
This sets the Low battery point to 25 percent (19 hex = 25 decimal). The low
battery setting is the point at which the user is alerted that the battery is low. The
user is notified only once for a low battery.
These are the default values. Developers can set these parameters from 0 (no
warning at all) to 99 (would nearly always warn). The warnings do not appear
when the terminal is on external power.
Using the Power Control Panel
The Power control panel displays information about current battery status and
allows you to set options that can conserve battery power.
There is also a battery usage indicator displayed. This indicator represents the
total cumulative time that the current main battery pack has been in use. If the
main battery is replaced with a new battery pack, the indicator will reset to 0:00.
Each battery is uniquely identified with a serial number that the Dolphin terminal
uses to track cumulative time. Also, if the terminal is placed in a HomeBase and
is running on external power, the indicator will cease counting. When the terminal
is removed from the HomeBase, the timer will resume.

Servicing the Battery Pack
For maximum battery life, you must service, or deep cycle, the battery twice
before initial use. It is also recommended that you service the battery once per
month. To deep cycle, insert the battery into the auxiliary well of the Dolphin
Intellibase+ charging/communication cradle, Dolphin QuadCharger or use the
Battery Conditioning Utility. See Chapter 6 for more information on using the
IntelliBase+ and Chapter 7 for information on using the QuadCharger.
Using the Battery Conditioning Utility
The Battery Conditioning Utility is used to condition or deep cycle a battery in the
Dolphin 7400/7450 terminal. The discharge/charge cycle minimizes battery
memory effects and ensures the battery data is correct. A complete discharge/
charge cycle may take up to 15 hours for a fully charged battery. The actual cycle
time will vary depending on the battery state when the cycle was initiated.
Follow these instructions to use the Battery Conditioning Utility to deep cycle the
battery before initial use:
1. Put the battery pack in the Dolphin terminal.
2. Connect the Dolphin 7400/7450 terminal to external power or place the terminal in the
HomeBase or IntelliBase. After starting the Battery Conditioning Utility, the Dolphin will
beep and then indicate an error if the terminal is not on AC power.
3. Select Start>Programs>HHP>Battery Conditioning to start the Battery Conditioning
Utility.
4. Touch the ‘Start’ button (or the ‘S’ key on non-touchscreen terminals) to start the battery
conditioning process. The terminal will beep and the process will begin in approximately
60 seconds.
5. Touch the ‘Abort’ button (or the ‘A’ key on non-touchscreen terminals). The terminal will
beep and the battery conditioning process will be aborted.

Charging the Battery Pack
You can charge the Dolphin’s main battery pack with one of the following
methods:
•
Place the battery pack in the Dolphin 7400/7450 terminal and then place the terminal in
the terminal well of a charging/communication cradle.
•
Place the battery pack in the Dolphin Quad Battery Charger.
•
Place the battery back in the Auxiliary Battery Well of the IntelliBase+.
Storing Batteries
To maintain top performance from batteries, follow the guidelines below when
storing them:
Avoid storing batteries outside the specified range of -4 to 104° F (-20 to 40°C) or
in extremely high humidity.
For prolonged storage, do not keep batteries stored in a charger that is connected
to a power source.
During long-term storage, battery deactivation may tend to occur, which may
cause charging to stop early during recharging after storage. This issue can be
handled by charging and discharging the battery several times. Also, the first
charging after prolonged storage may yield a lower than normal capacity. While
this will vary depending on the storage conditions, charging and discharging the
battery several times will almost completely restore capacity.
