Control Box
The control box sits inside the case and houses the electronics. The control box
should not be opened by anyone other than an approved Castle service engineer.
The isolation switch should be ON (indicating BLUE) when the case is in use and
switched off when the case is not in use,
for safe storage and to prevent battery
discharge.
The LED on the control box will illuminate
RED when the Charger is plugged in.
The LED will illuminate GREEN when an
external Battery Pack or external Power
Supply is plugged into the case.
If the LED illuminates AMBER then both the
Charger and External Power are being
used.
CAUTION:
Never use the ISOLATION switch to Turn OFF the instruments, always
shut down as outlined in the instruments operating manual. Doing so may result
in data loss or corruption.
