Cuff Not Detected

If the VitaCheck M1 displays "Cuff not detected" or Error E03, the monitor cannot sense the cuff connection. Follow these steps to resolve the issue.

Step 1: Check the physical connection

1. Disconnect the cuff air tube from the monitor by gently pulling the connector straight out.
2. Inspect the connector for dust, lint, or debris. Clean gently with a dry cloth if needed.
3. Reconnect the tube by pushing the connector firmly into the port until you hear and feel a click.
4. The cuff icon should appear on the display within 2 seconds of connection.

Step 2: Inspect the air tube

• Check the full length of the tube for visible cracks, kinks, or punctures.
• Ensure the tube is not pinched by the cuff fabric or caught under the monitor.
• If the tube shows signs of damage, replace it with a new Air Tube Set (MV-VM1-SP-TUBE).

Step 3: Test with a different cuff

If you have access to a second cuff (Small MV-VM1-CUFF-S or Large MV-VM1-CUFF-L), connect it to the monitor. If the replacement cuff is detected successfully, the original cuff or tube is faulty and should be replaced.

Step 4: Restart the monitor

1. Remove all batteries and disconnect USB-C power.
2. Wait 10 seconds.
3. Reinsert batteries or reconnect USB-C.
4. Reconnect the cuff and check for the cuff icon.
