3. Use the battery installation tool to remove the battery retaining ring.

Turn the ring counter-clockwise. Use the magnet in the tool to lift the

ring from the device case.

4. Inspect the O-rings on the e-module and case to verify they are present,

clean, and undamaged. Apply a very light coating of silicon-based O-ring

grease to the O-rings. (When replacing the battery, always replace the O-

rings.)

The Ranger Pro device uses two O-rings to seal the unit against dust and

moisture.

• 34x1mm O-ring on the e-module

• 35x1mm O-ring on the case

! NOTE

To maintain the device's IP67 dust and water-resistant rating and prevent leaks, you must install and

lubricate the O-rings properly.

5. Inspect the interior threads of the sensor case as well as the exterior threads of the battery retaining

ring to be sure they are not damaged or contaminated.

6. Verify that the positive end of the battery is up and then insert the

battery.

! NOTE

Use only approved D-sized lithium-thionyl chloride batteries for the

Ranger Pro sensors and repeaters. For ordering information, contact

Divigraph.

7. Use the battery installation tool to tighten the battery retaining ring.

Hand-tighten the ring until it contacts the battery, then torque to 5 N-m

(44 in-lb).
