Error Codes

Background This section is provided for the assistance of qualified and trained service
technicians only and is not intended for use by untrained or unauthorized service personnel. Failure to observe this precaution may void the warranty.
NOTE: If the warmer is not operating properly, check the following
before calling an authorized service agent:
Verify that the power to the warmer is on.
If applicable, ensure the female end of plug is securely seated in the warmer and that the male end of plug is in an appropriate, functioning outlet.
If applicable, examine the fuses. Replace the fuses, refer to topic How to Replace a Fuse.
If applicable, examine the high limit manual reset button. If the high limit manual reset button is tripped, reset the warmer, refer to topic How to Manually Reset the Warmer.
NOTE: All non-critical codes can be cleared using the ON/OFF button.
Critical errors (marked with a *) can only be cleared by setting the power switch at the rear of the warmer to the off (O) position and allowing the warmer to cool.

Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
1. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the warmer is used exceeds the applicable RF compliance level above, the warmer shou ld be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the warmer.
2. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [VI] V/m.
