Step 3. Charge the Main and Backup Batteries
The power supply for Dolphin terminals consists of two types of battery power: the main battery pack
that is accessible from the back panel, and the backup battery that resides inside the terminal. The main
battery powers the terminal. The internal backup battery charges off the main battery and maintains the
application data stored in RAM memory for up to 5 minutes when the terminal’s main battery pack is
completely discharged or removed.
Dolphin 7800 terminals are designed for use with the following 7800 charging devices and cables:
7800-HB, 7800-EHB, 7800-NB, 7800-CB, 7800-DEX, 7800-MC, 7800-MB, 7800-USB, and 7800-USBH.
See Chapters 12-17 for additional information on the individual device requirements.
Before Initial Use
Terminals are shipped with both batteries discharged of all power. The initial charging time for the main
battery pack is 4 hours for the standard battery pack or 6 hours for the extended battery pack. Connect
the terminal to one of the 7800 series charging peripherals to charge; see Peripherals for the 7800 on
page 3-3.
Note: Honeywell recommends charging the Dolphin terminal for at least 24 hours prior to initial use to ensure the
internal backup battery is fully charged.
We recommend use of Honeywell peripherals, power cables, and power adapters. Use of any non-Honeywell
peripherals, cables, or power adapters may cause damage not covered by the warranty.
Charging Using the Communication Cable
Ensure all components are dry prior to mating terminals/batteries with peripheral devices. Mating wet
components may cause damage not covered by the warranty.
Client Device Communication Cable (7800-USB)
Use only a UL Listed power supply, which has been qualified by Honeywell with an output rated at 5VDC
and 3A with the device.
