55800 Operation
If an external power source is connected to Port 1 it is used in
preference to the internal battery. When there is no external power
source connected, or if the external power supply fails, the internal
battery is used.
The 5800 receiver is supplied with two rechargeable lithium-ion
batteries, and a dual battery charger. The two batteries take
approximately eight hours to fully charge.
13.7.1 Power Output
The 5800 receiver does not supply power from either of its 2 ports.
13.7.2 Firmware
A receivers firmware is the program inside the receiver that makes
the receiver run and controls the hardware. You can upgrade the
firmware for the 5800 receiver using the WinFLASH utility provided
on the 5700/5800 CD.
For more information, see WinFLASH Software, page 159.
Warning Upgrading the firmware deletes all application files on the
5800 receiver.
