WayPoint PDA Connected to the back of a PC via the USB Cable on the left and the travel adapter on the right.

There are two types of USB hardware configurations used in PC’s.

its own 5 Volt power while the second gets its source of power from the USB connection on the

PC.

USB port. The PC itself must be powered up and the WayPoint PDA must be powered off.

some power from the USB hub but the unit will use more power than the hub can supply so the

unit will still need some battery power and will not be charged. You can verify whether the unit is

receiving a charge via the AC adapter or the USB connection by looking at the back of the stand.

There is a lamp showing power is available for battery charging and it is only lit when the AC

adapter is used.

storage medium requiring electrical power to remain operational. It is therefore essential that the
