SAFETY NOTICE
Great care has been taKdn in the destgn and manufaclure of thiB product to assure that no

shock hazard eirfsls on any exposed metal pan*. Internal service operations can expose the
technFcLan to hazardous line vollages and accldanfally caiise these voltages to appear on
exposed metal parts during repaon these products should only be periormed by those who are Ihoroughly familiar with the
precaullona necessary when working on this type of equipment.


To prolMl ihe ui#r, H li FHfutrvd that all ancloture parti and iifety [nteriocki be restored 1o
their original condition and the following tetti be peHormed t>efore feturning the pfoduci to
the owner after any lervlce oper alton,


Wug th6 AC line cord directly Into a line voltage AC receptacle (do not use an Isolation
transformer for this lest) and turn the product on. Connect the network (as shown below) In
series with aM e^Kposed metat parts and a known earth ground such as a water pipe or conduit,
Uaa an AC VOM of 5,000 ohms per volt or higher senaillvity to measure the voltage drop across
the network. Move the network connection to each exposed metal part (metal chassis, screw
heads, knobs and control shafla, esculcheor^. etc.) and measure the voltage drop across the
network. Reverse the line plug and repeal the measurements. Any reading of i volts RMS or
more Ja excessive and Indicates a potential shock hazard which must be corrected before
returning the product to the user.
