Frequency meter for retailers to identify the frequency of the original remote to duplicate
- Press the button: the word “SCAN” will be displayed.
- Place the original remote approximately 15–20 cm away, press and hold the button on the original remote whose frequency you want to identify until the tester display shows the frequency in MHz (e.g., 433.92 or 868.3).
- If the word “roLL” appears, the remote transmits a rolling code.
- If the tester cannot read the code within 10 seconds, move the remote closer to about 10 cm.
