2.13 Disconnecting the Model 1104 for Storage or
Seasonal Use.
If you plan to employ the Model 1104 as a seasonal “watchdog”
for a few months during the year, you must disconnect all wires
from the unit completely to avoid damage to the circuitry
when the unit is not in use. If the unit is unplugged but left in
place with all the sensors still connected, the wires act as antennae
that draw in any stray “electrical noise” from such devices as fans,
blowers, microwaves, etc.
