    Standard resistance:
    Tester connection
    		 Condition
    		 Specified condition
    AU1 - EAU
    		 No switch is pushed
    		 Approx. 100 kΩ
    AU1 - EAU
    		 SEEK+ switch: push
    		 Approx. 0 Ω
    AU1 - EAU
    		 SEEK- switch: push
    		 Approx. 0.3 kΩ
    AU1 - EAU
    		 VOL+ switch: push
    		 Approx. 1 kΩ
    AU1 - EAU
    		 VOL- switch: push
    		 Approx. 3.2 kΩ
