Intraoral Sensor Sheath Removal Guide

Schick and Fona intraoral sensors are designed and tested to withstand years of normal daily use and the most common reason for sensor failure is excessive force applied to the sensor body and/or cable. To prevent damage to your sensors while removing the sheath, please follow these guidelines.


  1. Do always be gentle with the cable while removing the sheath.
  2. Do follow the four steps in the images below.


  1. Don't pull on the cable when removing the sheath.
  2. Don't start by pulling the sheath off the aiming bar and adhesive.
Sheath Removal Step 1

1. Keeping the sensor attached to the positioning tab and aiming bar, grasp the aiming bar where it joins the sensor.
