SAFETY INSTRUCTIONS SYMBOL
SINGLE PAIR WITH TWO SELECTIONS SPDT SWITCH
DESCRIPTION
Alerts you to the presence of insulated dangerous voltage, or indicates a live area on the circuit, that may be sufficient to constitute a risk of shock.
DUAL PAIR WITH TWO SELECTIONS SPDT SWITCH
Alerts you to important maintenance instructions in the accompanying literarture.
DUAL PAIR WITH THREE SELECTIONS SPDT SWITCH
Important: The designated circuits where implemented 2 (two) different ground connections: 4−POS WITH 2−COM ROTARY SWITCH
1. Power Ground The Power Ground by mean the common ending for all sub−circuits with relative high−current voltage intensity and contains stream/signal that may be carrying the AC hum.
+ RELAY / VOLTAGE CONTROLLED SWITCH
2. System Ground
−
The System Ground by mean the common ending for all high−sensitive sub−circuits and ending for those processes the small audio signal.
