1.6 GROUND LIFT Switch (2)
The signal GROUND LIFT switch should be set to the GROUND position. If the PAS 400 hums
when connected to other equipment, setting the switch to the GROUND LIFTED position may
reduce or eliminate the hum.
1.7 Fuses (3) and (4)
Disconnect the PAS 400 from any external power supply (mains or battery) before changing
or inspecting fuses.
Only the following fuse types can be used
1.8 Powering with a 12-16 Volt DC External or Auto Battery (5)
The "EXT BATTTERY 12 - 16 VDC" socket is accessible by removing the sealing cap.
A plug-in connector for this is socket available. Please note the correct polarity (labelled as
"+" and "-" by the socket). Incorrect polarity will not cause damage, but the internal battery
will then power the PAS 400.
1.9 Power Switch (6)
The power switch has three positions:
When the system is switched On (to Position I or Position II), there is an automatic 3-second
delay before it is operational.
When the (optional) built-in wireless receiver is not being used, set the Power Switch to
Position II to conserve battery power and to get the longest run-time per charge.
When switching from Position I to Position II (or visa versa), first switch to Position 0 and wait
5 seconds before switching to the next position, otherwise, the Deep Discharge Cut-Off Circuit
may be activated (if activated, switch to Position 0 and wait 30 seconds before switching to
Position I or II.).
