Controls
POWER
Controls primary AC power. The switch lights if AC power is
present.
CARRIER TEST
Pressing this button simulates the detection of a carrier “click” on
the operation frequency. Pressing the button three times within 5
seconds will set the unit to the lowest brightness setting.
TIMER RESET
Pressing this button will reset the timer to the start of the timer
selected by the TIMEOUT switch.
PANEL TEST
This button will light all indicators visible on the front panel while
the switch is pressed down.
TIMEOUT
This switch will set the timer to hold lighting controlled by the RCE
to the indicated time: 1, 15 (FAA standard), 30, 45 or 60 minutes.
The one minute setting is used for internal testing.
SENSITIVITY
Min/Max
This will adjust the sensitivity of the receiver to prevent the
reception of unwanted signals. This is especially important for
Unicom frequencies used by nearby airports. Setting the control
closer to Min will prevent transmissions further away from keying
the L-854 RCE.
VOLUME
Min/Max
This will adjust the volume of transmissions monitored by the
internal speaker and the headphones.
DECODER
Enable/Disable
Setting the DECODER switch to Disable will prevent any signal
from activating the L-854 Radio Control Equipment. The same
function can be accomplished through a remote signal through the
Terminal Block. Note that the STATUS light will go off when set to
the Disable position.
