Carver 2157 MONTEGO Owner's Manual page 11

Ignition Switch(s) and aI/ instruments, controls, etc.
should be protected from the weather when not in use.
Carver offers appropriate weather covers for each
model. Excessive exposure can lead to gauge and
Ignition Switch difficulties.
Electronic gauges are affected by static electricity that
builds-up on the glass face. Periodic washing of the
gauge face with warm water and mild liquid detergent
will help eliminate the static electricity problem and
improve gauge accuracy.
