2. The AV equipment connected to the S Type unit reboots or turns off during or after
the unit switches to battery power.
3. The REPLACE BATTERY indicator is on (lit).

with an accompanying message that explains what action to take. If you

Probable Cause: Battery is not connected.
Solution: Remove the front display panel by grasping the
sides and pulling straight back. The battery is
located on the right side of the unit. The black
battery connector should be pushed snugly into the
battery socket located just to the left of the battery
pack. Reference the Connect Battery section to
view photographs related to this procedure.
Probable Cause: No power or insufficient power is available at the
wall outlet.
Solution: Ensure that the wall outlet has good power by
checking it with a voltmeter, or by plugging the
power cord of a known good device into the outlet.
