Replace a Sensor+ Head

Follow the instructions below if you need to replace a Sensor+ head.

You must replace the head with a like-for-like replacement.

Sensor+ contact heads do not require calibration certificates.

Unclip the old head from the Power Unit Battery (PUB).

The Power Unit Battery (PUB) is a white plastic box connected to the sensor head by a cable (see image 1).

Clip the new head onto the PUB.
Place the Magnetic Tag on the bottom-left corner of the sensor and hold it there for about 3 seconds. During this time, the Mode LED (right) should flash green, then amber. Remove the Magnetic Tag after this sequence completes.

The Magnetic Tag is a small white magnet (see image 2).

Caution: The Magnetic Tag may interfere with pacemakers and implantable cardioverter-defibrillators (ICDs). Keep the tag at a safe distance from such devices

Place the Magnetic Tag on the bottom-left corner of the sensor and hold it there for exactly 52 seconds.
After removing the Magnetic Tag, you should see the following LED pattern:
1. The Mode LED (right) will flash green.
2. The Mode LED (right) & Health LED (left) will flash green, then amber & then red.
3. The Health LED (left) will flash green.

If you do not see the LED pattern described above, repeat step 4. Ensure that you press the Magnetic Tag for exactly 52 seconds.

Wait for 1 hour.
View the sensor in the Control Centre. If it is:
- Green: You have successfully replaced the sensor head.
- Amber: You have successfully replaced the sensor head.
- Red: You have successfully replaced the sensor head.
- Black: Contact us for assistance.
