Follow these instructions to perform basic maintenance tasks.

Check the main body gasket every time a SureCross device is opened.

9.2 Replacing the Rotary Dial Access Cover

Check the rotary dial access cover o-ring every time the access cover is removed.

9.3 Battery Replacement

9.3.1 Replacing the Battery (DX81 and DX81H Battery Supply Module)

For outside or high humidity environments, apply conductive grease to the battery terminals to prevent moisture and cor-
rosion buildup.
To replace the lithium "D" cell battery in the DX81 FlexPower
1. Unplug the battery device from the SureCross device it powers.
2. Remove the four screws mounting the battery pack face plate to the body and remove the face plate.
3. Remove the discharged battery by pressing the battery towards the negative terminal to compress the spring. Pry up
on the battery's positive end to remove from the battery holder.
4. Replace with a new battery. Only use a 3.6V lithium battery from Xeno, model number XL-205F.
5. Verify the battery's positive and negative terminals align to the positive and negative terminals of the battery holder
mounted within the case. Caution: There is a risk of explosion if the battery is replaced incorrectly.
6. After replacing the battery, allow up to 60 seconds for the device to power up.
7. Properly dispose of your used battery according to local regulations by taking it to a hazardous waste collection site, an
e-waste disposal center, or any other facility qualified to accept lithium batteries.

SureCross DX80 and Performance DX80 Product Manual
Replace the gasket when it is damaged, discolored, or showing
signs of wear. The gasket must be:
• Fully seated within its channel along the full length of the
perimeter, and
• Positioned straight within the channel with no twisting,
stress, or stretching.
Replace the o-ring when it is damaged, discolored, or showing signs of wear. The
o-ring should be:
• Seated firmly against the threads without stretching to fit or without
bulging loosely, and
• Pushed against the flanged cover.
When removing or closing the rotary dial access cover, manually twist the cover
into position. Do not allow cross-threading between the cover and the device's
face. After the cover is in place and manually tightened, use a small screwdriver
(no longer than five inches total length) as a lever to apply enough torque to
bring the rotary dial access cover even with the cover surface.
