Remote Control - Landoll 334C Operator's Manual

4-6 REMOTE CONTROL

4-6.1 Care should be taken not to subject the
transmitter to excessive abuse.
4-6.2 To remove dirt, grease, and oil, wipe
with a cloth soaked with soap and water. For
hard stains, a light alcohol based cleaner
should be used.
4-6.3 Should moisture build up inside the
transmitter housing, remove the cover and
allow it to air dry. This process may be sped
up using a blow dryer set on a low heat
range.
4-6.4 If a unit fails completely or one or two
outputs are not working, complete the follow-
ing procedure:
a. Remove the cover on the receiver (See Fig-
ure 4-5).
b. With power to the receiver, the Power Indi-
cator LED will be on. Turn transmitter power
on. At this time the receivers RF Indicator
LED will be on for 10 seconds and you will
hear the power relay engage. To verify that
the power relay is engaged and that the trans-
mitter is transmitting, activate the emergency
stop on the transmitter. This will disable the
power relay and the transmitter will transmit
for 10 seconds. The RF and Power Indicator
LED's will be on.

c. To reset the unit, turn the transmitter power
off and back on. At this time the receivers RF
Indicator LED will be on for 10 seconds and
you will hear the power relay engage.
d. When a function is activated on the trans-
mitter, three LED's are turned on in the re-
ceiver: RF Indicator LED, Output Status Indi-
cator LED, and Power Indicator LED (always
on).
e. If the power relay does not engage, the ad-
dress codes may not be matching. Compare
the 12 position address switches in both
transmitter and receiver and then repeat
steps a. and b. If they both match and still
the power relay does not engage, set all 12 of
the dip switches to the off position in both the
receiver and transmitter and then repeat
steps a. and b. Call the factory for a new ad-
dress code or to have the unit shipped back
for repair.
