Sigma bike computer issue

I need to change the battery on my Sigma 1106 bike computer and I have not been able to detach the main unit from its 'station'. (I've removed it before...but I can't recall just how it comes off.)

The owner's manual is mainly diagrams (as well as brief instructions in several languages) but does not seem to address actual removal of the unit. I believe it twists off, but gently twisting in either direction has not been successful. Am I missing a step? There doesn't appear to be a 'release' tab (like my other bike's Cateye computer.).

Would appreciate any suggestions; thanks in advance for your help!

I have a Sigma and it's a gentle turn to the left to remove the computer from the base.

Kmehrzad, do you need to push down on the computer unit while turning-or just twist it to the left? (I'm probably confusing this process with opening childproof medicine bottles...)

Thank you for taking the time to respond!

No need to push down, just a gentle turn to the left. (LOL, you're a true mom at heart, eh? with the childproof medicine bottle twist action)

I guess so-even though my "baby" is now almost 29...LOL

I use a Sigma 2209, and to remove it from the mounting bracket is described exactly like everyone has said here...a gentle turn to the left, with no push down required. Infact, mine comes off so easily...that sometimes I worry that it might just suddenly "pop" off when I hit a big bump in the road...but it hasn't happened so far.

If the adhesive tab under the base unit gives up you'll need to hold the base while you twist the computer - otherwise you're just twisting the computer and the base on the rubber bands.
