SAFETY PRECAUTIONS
WARNING:
Service should not be attempted by anyone unfamiliar with the necessary precautions for this recording or playback equipment. The following precautions are necessary during servicing:
1. Many electrical and mechanical parts in this recorder have special safety-related characteristics for providing protec­tion against shock, fire and other hazards. These charac­teristics often go unnoticed in a visual inspection, and the protection afforded by them cannot necessarily be ob­tained by using replacement components with higher rat­ings (voltage, wattage, etc.).
2. Replacement parts having special safety-related charac­teristics are identified in this manual, and in the schematic diagrams, by the symbol ! . These components have values that are of special significance to product safety. Should any component (identified by the symbol ) need to be replaced, use only the part designated in the parts List. Do not deviate from the specified resistance, wattage, and voltage ratings.

Monitor
3. Before returning the set to the customer, always perform an AC leakage current check on the exposed metallic parts of the cabinet, such as terminals, screwheads, metal over­lays, etc. to be sure that the set is safe to operate without the danger of electrical shock, Plug the AC line cord directly into a 120 V AC outlet. (Do not use a line isolation trans­former during this check.) Use an AC voltmeter with a sensitivity of 5000 ohms per volt (or more) as follows: Connect a 1500 ohms, 10 watt resistor, paralleled by a 0.15 mfd, 150 VAC capacitor, between a known good earth ground (water pipe, conduit, etc.) and the exposed metallic parts, one at a time. Measure the AC voltage across the 1500 ohms resistor and 0.15 mfd capacitor combination. Reverse the AC plug at the AC outlet and repeat the AC voltage measurements for each exposed metallic part. The measured voltage must not exceed 300 mVrms. This corresponds to 200 µA AC. Any value exceeding this limit constitutes a potential shock hazard and must be corrected immediately.
