Powering the Dolphin HomeBase

The terminal requires 9.5 volts DC input for communications and battery charging; the power adapter on the power cable converts
the voltage from the power source to 9.5 volts DC. Only power adapter cables from Hand Held Products converts the voltage
appropriately.
We recommend that you leave the Dolphin HomeBase connected to its power source at all times, so that it is always ready to use.
1. Connect the power cable to the DC jack on the rear panel of the HomeBase.
2. Connect the power cable to the power adapter.
3. Plug the power adapter into the power source.
4. The HomeBase is now powered. When a terminal is inserted into the terminal well, the HomeBase powers the terminal,
charges the terminal's main battery pack, and launches ActiveSync communications (if applicable.)
