6.1 Emitter Life
The life expectancy of the cavity depends on the time and temperature of operation. The higher
the temperature, the shorter the life span. At temperatures near the upper end of the range,
the life expectancy is shortened by approximately 30%. Do not try to clean the emitter surface.

Unusual noises and smells when applying power.
