2 Charging the Main Battery and Backup Battery
WARNING Use only 2700 mAh NiMH battery packs provided by HHP. The use of any other
battery pack in the Dolphin terminal will void your warranty and may result in damage to the
Dolphin terminal or battery.
The terminal’s NiMH battery is not conditioned at the factory and is shipped
discharged of all power and inserted in the Dolphin terminal.
WARNING Although the Dolphin 7400/7450 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.
For maximum battery life, HHP recommends that you deep-cycle the battery
twice before initial use. It is also recommended that you service the battery once
per month. Refer to the section on Managing Battery Power in Chapter 3 for
further information on deep-cycling the battery.
After deep-cycling the battery, the terminal’s NiMH battery must be charged
before using it for the first time. To charge the main battery pack:
1. Place the main battery pack in the Dolphin 7400/7450 terminal.
2. Place the terminal in the terminal well of the Dolphin HomeBase™. Time to
Charge: 3.5 hours for the main battery; 8 hours for the back-up battery
As the main battery pack charges, the internal back-up battery also charges. 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

Waking the Dolphin From Sleep Mode
The Dolphin 7400/7450 terminal is never actually turned off. To conserve power,
the Dolphin suspends operation, or goes into “sleep mode”when it is inactive for a
programmed period of time, as defined by your application. The screen is blank
when the Dolphin is in “sleep mode.”Press the ON/SCAN key to wake the
Dolphin terminal from sleep mode, and you can start working where you left off.
The Dolphin terminal also goes into sleep mode if you remove the main battery
pack. To wake the Dolphin terminal from sleep mode, install a charged battery
and press the ON/SCAN key.
WARNING If the main battery and back-up battery are ever fully discharged of power,
the terminal will cold boot. The terminal will be restored to its original state. All data
stored in RAM memory also will be lost.
