    f.   When the product displays an abnormal condition. Any noticeable abnormality in the product indicates that the product 
needs servicing.

parts specified by the manufacturer, or those with the same characteristics and performance as the original parts. Use of 
unauthorized parts can result in fire, electric shock and/or other danger.
 16.   Safety checks — Upon completion of service or repair work, request the service technician to perform safety checks to 
ensure that the product is in proper operating condition.
 17.   Wall mounting — When mounting the product on a wall, be sure to install the product according to the method
