The Temperature alarm monitors the internal temperature of the unit based on specific points inside
the radio chassis. It is normal for the internal temperature to be above the ambient temperature, so the
temperature reading may be higher than the highest specified ambient temperature. When the internal
electronics reach a point that is higher than the normal temperature rise at the highest ambient
temperature, the temperature alarm turns yellow. Power down the radio as soon as possible, and
investigate the cause of the temperature rise before the radio is put back into service. In almost all
cases, a temperature alarm is due to an external cause.
