Data Sheet

If the device is receiving a valid RC signal which suddenly stops, it will take 130 ms before the signal

is recognized as bad. From there, it will take 500 ms before the safe-start mode becomes active, so

there will be a total of 630 ms between the loss of the signal and the re-activation of safe-start mode.

To get out of safe-start mode and activate the switch, you should move the input to the off position and

then move it to the on position.

Even with the safe-start feature, unexpected activation of the switch is still possible. With the

Pololu RC Switch with Relay, one way this could happen is if the switch is activated but the

logic power supply is at 3 V, which is too low to actually turn on the relay. If the logic power

rises from 3 V to 5 V then the relay could turn on unexpectedly.
