MODIFICATION NOTICE. SERVICE MANUAL MODEL E1K E1C DN-F650R SOLID STATE/USB RECORDER • For purposes of improvement, specifications and design are subject to change without notice. • Please use this service manual with referring to the operating instructions without fail. • Some illustrations using in this service manual are slightly different from the actual set.
SAFETY PRECAUTIONS The following check should be performed for the continued protection of the customer and service technician. LEAKAGE CURRENT CHECK Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis resistance check.
NOTE FOR SCHEMATIC DIAGRAM WARNING: Parts marked with this symbol z have critical characteristics. Use ONLY replacement parts recommended by the manufacture CAUTION: Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power cord is less than 460 kohms, the unit is defective.
