2) Remove the 2 Philips screws by turning them counter clockwise.
3) Gently remove battery by pulling the ribbon upward.
4) Re-position the ribbon under a fresh battery, observing the correct polarity.
5) Turn unit back on by holding the key until ‘boot’ appears on the display.
6) Replace cover, and the two screws. DO NOT OVER TIGHTEN THE SCREWS. These screws will
not vibrate loose, and gentle tightening is all that is required. MicroTim XB is not warranted for
stripped holes. Also, the lid is recessed to clear the battery and fits correctly only one way. Observe
the recess in the cover.
Appendix A – Frequently Asked Questions
Question: When in ‘ftmb’ or ‘metr’ modes, I cannot reach the exact number I am trying for.
Why not?
Answer: MicroTim XB is changing the barometric pressure internally by 0.01 inHg (9.3 feet) then converting to
mbar or kPa. Pick the number closest to the setting you are trying for.
Question: This is a barometric altimeter. How does the sensor access the local pressure?
Answer: MicroTim XB has an unsealed rear cover which allows the internals to equalize with external air pressure.
In addition, a small hole in the cover is present to ensure equalization. The rear cover and this small hole should
never be sealed or the accuracy of the unit will be severely affected.
Question: What if I have a problem I cannot seem to solve?
