TECHNICAL PRECAUTIONS
Operating temperature: 0 C to 40 C (+32 F to +104 F)
The video image may distort when the door release is activated. But
this is not a unit malfunction.
Cleaning: Clean the units with a soft cloth dampened with a neutral
household cleanser. Do not use any abrasive cleaner or
cloth.
If there is a system malfunction, turn the POWER switch at the
monitor station OFF and back ON again. If this does not solve
the problem, unplug the DC power supply and contact a qualified
technician for service.
