KV-29FS140 SAFETY CHECK-OUT The AC leakage from any exposed metal part to earth ground and from After correcting the original service problem, perform the following all exposed metal parts to any exposed metal part having a return to safety checks before releasing the set to the customer: chassis, must not exceed 0.5 mA (500 microamperes).
KV-29FS140 Self Diagnosis SELF-DIAGNOSTIC FUNCTION Supported model The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY LED indicator will automatically begin to fl ash. The number of times the LED fl ashes translates to a probable source of the problem. A defi nition of the STANDBY LED fl ash indicators is listed in the instruction manual for the user’s knowledge and reference.
