• The maximum current supplied through a charging peripheral is 2.0A.
• The maximum current supplied by the USB wall charger is 900mA.
• The maximum current supplied by a USB Host can vary from 100mA to 500mA.
Do not attempt to charge the terminal from a 100mA source. An active Dolphin terminal uses
more current than supplied by a 100mA source causing the terminal to continue to draw power
from the battery.
Note: Placing the terminal in Suspend mode while charging reduces the current draw of the terminal and shortens
the charging time of the battery.
Touch All Apps > Settings > Battery to verify the battery is charging.
Charging a Severely Low or Completely Discharged Battery
Use one of the following options to charge a severely low or completely discharged battery.
1. Insert the battery into the auxiliary battery well of the HomeBase. When the auxiliary battery LED on
the HomeBase turns green, the battery is fully charged.
2. Dock the terminal into the charging well of a peripheral (e.g., HomeBase, eBase, Net Base or
ChargeBase). The terminal starts to boot as soon as power is supplied by the base.
Note: To prevent the possible loss of unsaved data, do not remove the terminal from the base until the battery
has sufficiently charged.
Touch
> Settings > Battery to view detailed information on the status of the battery.
3. Charge the terminal from a wall power outlet using the USB Charge/Communication Cable and
power supply provided with your terminal. As the battery charges, the general notification LED
cycles through green, red, amber and off. The LED continues to cycle until the battery reaches a
safe charge threshold and the terminal begins to boot. The length of time before the battery reaches
a safe charge threshold varies depending on the extent of the battery discharge.
Note: If the general notification LED does not start to cycle after approximately 5 seconds when power is
applied, press the Power button once.
4. Charge the terminal from a USB host device (PC) using the USB Charge/Communication Cable.
Note: Inadequate source current may interfere with effective battery charging; see Important Charging
Guidelines on page 3-13 for additional information.
As the battery charges, the general notification LED cycles through green, red, amber and off. The
LED continues to cycle until the battery reaches a safe charge threshold and the terminal begins to
boot. The length of time before the battery reaches a safe charge threshold varies depending on the
extent of the initial battery discharge level and the current supplied by the USB charging source.
Note: If the general notification LED does not start to cycle after approximately 5 seconds when power is
applied, press the Power button once.
Battery Charge Status Symptom
Severely Low Pressing the Power button does not wake the terminal from Suspend mode. The general
notification LED may flash once when the Power button is pressed.
Completely Discharged Pressing the Power button does not wake the device and the general notification LED
remains off.
