## Questions & Answers

**Q: I have a v3.0 how do I access the battery?**
A: Thanks for your question.  Turn the calculator over and see that there are four small screws.  Using a small screwdriver, remove the two screws under the hinge.  Then, using a blunt edge instrument such as a letter opener or butter knife, slide it between the top and bottom and pop the clips around both sides and the bottom.  You will be replacing with a CR-2032 battery.  Please feel free to call our Tech Support Team at 800-854-8075, Ext 6500 is you have any questions.

**Q: I see on the calculated industries web site that they are shipping the v3.1 model. Is this the same newest model or is it an older version?**
A: mine says Model 44080 v3.1...i assume this is the latest model.

**Q: viewing in sunlight a problem???**
A: No problems at all, this is the big version of the small one. This is more for office use. The smaller one is more for the filed.

**Q: Description says it does full metric but one of the reviews says it will not convert mm.  Can somebody confirm?**
A: It converts to mm (and cm and m), in linear, area or cubic. Look above the #9 key in photo.  The keystroke to convert a displayed value from another unit to mm is simply [Conv] 9
To directly enter a mm value, you hit value e.g., 123 [Conv] 9.
Hope that helps.
