KP- 43T90 / 48V90 / 53V90 / 61V90 SAFETY CHECK-OUT Leakage Test After correcting the original service problem, perform the following The AC leakage from any exposed metal part to earth ground and from safety checks before releasing the set to the customer: all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microamperes).
KP- 43T90 / 48V90 / 53V90 / 61V90 Self Diagnosis SELF-DIAGNOSTIC FUNCTION Supported model The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/TIMER LED 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/TIMER LED fl ash indicators is listed in the instruction manual for the user’s knowledge and reference.
