MICROWAVE OVENS
R-1210F, R-1211F, R-1214F,
This is a supplemental Service Manual for Microwave Oven models:
R-1210F, R-1211F and R-1214F.
These models are quite similar to the base models:
R-1210, R-1211 and R-1214.
This supplemental manual must be used in conjunction with the base model service manual for
complete operation, service, safety and replacement parts information.
This supplemental manual is being issued to comply with the new FCC standards, that all
Microwave models produced from July 2005 must have a noise filter unit included, plus any
associated parts.
In the interest of user-safety the oven should be restored to its original condition and only parts identical to those specified
should be used.
WARNING TO SERVICE PERSONNEL: Microwave ovens contain circuitry capable of producing very high voltage and
current, contact with following parts may result in a severe, possibly fatal, electrical shock. (High Voltage Capacitor,
High Voltage Power Transformer, Magnetron, High Voltage Rectifier Assembly, High Voltage Harness etc..)
