Initial Setup
- Ensure the system operates within the allowed temperature range (-20°C to 60°C).
- Avoid placing the antenna near metals or materials containing metal flakes to prevent signal disruption.
7. Pairing the Transmitter and Receiver
The pairing process ensures a secure connection between the footswitch (transmitter) and the receiver.
Steps for Pairing:
- Press the pairing button inside the transmitter’s battery compartment.
- The blue LED on the transmitter will start blinking.
- Press the pairing button on the receiver.
- The corresponding LED on the receiver will start blinking.
- Once the transmitter and receiver detect each other, their LEDs will light up for 5 seconds.
- Press the transmitter’s pairing button again to confirm the connection.
- The LEDs will blink three times to indicate successful pairing.
Note: If the process fails within 30 seconds, the system will enter sleep mode and require restarting the pairing process.
8. Unpairing (Removing the Connection)
Scenario 1: The Transmitter is Active and Within Range
- Press and hold the transmitter’s pairing button for 5 seconds.
- The blue LED will light up for 3 seconds and turn off, indicating unpairing is complete.
Scenario 2: The Transmitter is Not Active or Missing
- Press and hold the receiver’s pairing button for 5 seconds.
- The corresponding LED on the receiver will turn off, indicating the transmitter has been removed from the network.
9. Regular Maintenance
Routine Checks
- Inspect the footswitch weekly to ensure:
- Proper activation when pressed and deactivation when released.
- The housing is intact and not damaged.
- Replace batteries at least once a year, even if the system is operational.
