KV-PG14P40/PG14L70/PG14L70/H RM-952 SELF DIAGNOSTIC FUNCTION The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/TIMER lamp will automati- cally begin to flash. The number of times the lamp flashes translates to a probable source of the problem. A definition of the STANDBY/ TIMER lamp flash indicators is listed in the instruction manual for the user’s knowledge and reference. - Page 6 KV-PG14P40/PG14L70/PG14L70/H RM-952 2.
