Ambient Control
No.25 has an array of ambient lights on each side, outboard of the feet. The intensity of these lights can
be controlled with the 4 position AMBITET CONTROL switch. Starting with the switch in the far counter
clockwise position, the lights are off, as the switch in moved to the next three positions, the intensity will
increase. The ambient lights can be triggered off for theater viewing with a common 12VDC trigger. 0V at
AMBIENT TRIG keeps the lights ON, +12V at this trigger input turns them OFF.
Remote Control Battery Installation
No.25’s Remote Control Unit requires two AAA batteries. These are not installed but are supplied. To install
or replace batteries in the Remote Control Unit, first remove the bottom aluminum cover by using the
supplied 2.5mm Hex key to loosen the two visible screws. With the bottom cover removed, you will see a
battery holder, which will accept two AAA batteries. Follow the images on the holder for proper orientation
of the batteries. After installing the batteries, test the unit by setting the SECURITY switch to UNLOCK and
turning one of the knobs. If the batteries are installed properly, you will see one of the red LEDs on the
remote control’s front panel illuminate. Replace the bottom cover and tighten the two screws using the
supplied Hex key. Battery life can be extended if the SECURITY toggle switch is left in the LOCK position
when the Remote Control is not in use.
