INDICATORS
1. Power indicator. When lit, this shows that there is power to the unit.
2. Heater indicator. When this is lit or flashing, it indicates that the heater is heating the unit or
controlling the temperature. If the oven is above the set temperature then the indicator will be off.
3. Over-temperature indicator. If this is lit, it indicates that the unit has developed a fault and the
over-temperature cut-out has been triggered. This will cause the heater to be switched off and the
unit will begin to cool even if the heater light is on.
