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
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 e-module retaining ring to be sure they aren’t
damaged.
6. Verify that the positive end of the battery is up and then insert the battery.
Use only approved D-sized lithium-thionyl chloride batteries for the Ranger Pro
sensors and repeaters. For ordering information, see the
Ranger Pro Datasheet
(document 125M5237).
7. Use the magnetic Ranger Pro 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).
