Useful tips for sensor wear1

Applying your sensor

Sensors stick better when you wash, clean and dry your skin before application.

  • Wash

    Only use non-moisturizing, fragrance-free soaps to wash the area where you’ll apply the sensor.

  • Clean

    Use the alcohol wipe provided in the sensor kit to remove any oily skin residue.

  • Dry

    Allow your skin to fully dry before applying the sensor.


Before you apply the sensor:

  • Be sure to choose an approved application site − the back of your upper arm

  • Do not use body lotion or cream where you’ll apply the sensor as it may leave an oily residue on your skin that could affect sensor adhesion

  • Shave any excess arm hair as it can get caught between the sensor adhesive and skin

Keeping your sensor in place

Pat dry

After a shower or swim, take extra care when towelling off to avoid catching or pulling off your sensor.

Dress for success

Try to give your sensor room by wearing loose-fitting clothing and lightweight material.

Protect it during contact sports and heavy exercise

Be sure to select a site on the back of your upper arm that will minimize the risk of knock-off, and consider using an over-bandage.

Slow down

When dressing or undressing, be careful that you don’t catch your undergarments on the sensor.

Hands off

Avoid playing with or pulling the sensor while wearing it.

Easy does it

Be careful not to catch your sensor on a doorway, car door, seat belt, or furniture edges.
