Remote On/Off

Output is on if remote on/off (pin 3) is open circuit.

Output is off if 2-4 mA current is applied to remote on/off (pin 3) via 1 k

Ωresistor.

Maxiumum pin voltage is 5 V and maximum current into pin 3 is 4 mA.

Note: Output may be affected with current into the pin as low as 10 µA.
