The battery on the Imaging ATR Accessory pressure sensor needs replacement
On the left side of the Pressure Sensor Housing, there is a battery holder that inserts into the unit. This is just in front of the silver knob.
- Pull on the end of the battery holder that sticks out slightly from the left side of the Pressure Sensor Housing and slide the holder from the unit.
- Remove the coin battery from the holder, observing the polarity of the battery.
- Insert the new coin battery into the holder in the proper orientation.
- Reinsert the holder into the Pressure Sensor Housing.
