2.3 FRONT PANEL SECTION

Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List. The mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when replacing, be sure to use parts of identical designation. When ordering resistors, first convert resistance values into code form as shown in the following examples.
Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%, and K=10%). 561... RD1/4PU 1 J 560 473... RD1/4PU 3 J 47k 0.5 R50... RN2H R K 1 1R0... RS1P 1 R 0 K Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5621.. RN1/4PC F 5.62k

MAINTENANCE OF EXTERNAL SURFACES
Use a polishing cloth or dry cloth to wipe off dust and dirt. When the surfaces are very dirty, wipe with a soft cloth dipped in some neutral cleanser diluted five or six times with water, and wrung out well, and then wipe again with a dry cloth. Do not use furniture wax or cleaners. Never use thinners, benzene, insecticide sprays or other chemicals on or near this unit, since these will corrode surfaces.
