Startup and Operation

Antenna operation
CAUTION
Don't exceed the rated power capacity of the antenna.
To obtain the best performance and dependability, read and follow the mainte-
nance and troubleshooting recommendations in
Chapter 5
of this manual.
De-icer system
operation
CAUTION
Don't leave the de-icer on for extended periods when the weather is
above 50° F (10° C); doing so may shorten the life of the heater ele-
ment(s).
There is a generous margin of safety built into the de-icer system, and opera-
tion for prolonged periods below 50° F (10° C) will not harm the system. If
icing conditions are expected, the heaters should be turned on in advance as a
preventive measure. It is much easier to prevent ice formation than to remove
a heavy coating.
Shively Labs de-icer control
system
If you have the Shively Labs de-icer control box and dual-setting thermostat,
you have the choice of manual or automatic operation. There are three switch
settings: AUTOMATIC, OFF, and MANUAL.
• When the switch is set to AUTOMATIC, the thermostat turns the
heaters on and off according to the temperature.
• When the switch is set to OFF, the thermostat is overridden and the
heaters will stay off no matter what the temperature.
• When the switch is set to MANUAL, the thermostat is overridden
and the heaters will stay on no matter what the temperature.
