PREPARATION
Using a USB External Power Supply
Use a commercially available USB external battery with USB Micro-B connector.
Note 1: The USB external battery will take priority over the AA batteries if
you turn on the power while the AA batteries remain in the battery
compartment.
Note 2: Be sure to turn off the power when you remove the USB external
battery while the AA batteries remains in the battery compart-
ment. Although this does not lead to damage, it may cause an
operation error or initialize your settings on the STAR BOOK ONE.
Note 3: If the USB external battery is drained ( its power voltage is drop-
ping), the display on the STAR BOOK ONE begins to blink. If this
happens, exchange the USB external battery for new ones (or
fully recharged ones).
Note 4: When you unplug the power cable, be sure to hold the connector
part and pull it straight out. Unplugging by grabbing the cable par
t may cause a wire to snap.
Note 5: Avoid pulling or bending a part of the power cable adjacent to the
connectors. It may cause a wire to snap.
Note 6: Do not use the power cable in a folded and tied condition. It may
cause electrical shock or fire.
