you grab the base of the round unit and turn it about and inch clock wise. Should feel it stop and than you can pull it down from the mount base and see the bottom of the unit in your hand. Should see small like square plastic trap door to open and the battery will be in site to replace. reverse the process with only difference is when placing unit back on the base it will turn counter clock wise. Very simple process but will need step ladder or good chair to stand on to reach if on the ceiling.

You must twist the detector bit which then comes off of the mounting plate. It's not difficult at all.

The indentation on the top above the logo slides away from the black button. That's where you change the batteries.

I have not had to open it up to change it, but figure it takes a button battery. There are two tiny screws to open the little case.

It is really easy to change the batteries! Just pop the tab and the cover comes off, the old battery falls out and you can drop the new one in and the cover goes back on =]

I do not believe you can replace the battery. I contacted the seller of mine about this and got conflicting info. They lastly told me to pry off the back to replace the battery which I believe will break the unit if attempted. My 2 still work so I have not tried it yet.

To change the batteries, you need a very fine phillips screwdriver. It is like doing surgery, easy for something to slip out of place.

You can't change the battery. It's permanently closed. I don't think you've been able to change the batteries in small calculators for 30 years.

Place a flat screw driver in the gap below the enter key and slide down the cover. Swap the 9V battery & reattch the cover.

YouTube videos will show you how to replace the battery however it is very easy to do. I did not even use the tool provided. Gently remove back of case with your fingernails. Go all around the outside of the case working it a little at a time. Pry wire connection apart (don't pull on wires) and replace battery. Snap back of case into place. Make sure you completely charge battery before turning tablet on. good luck.

I can confirm what Denise typed below. If you look at the grip handle -- where it contacts your palm -- on the MK2 there is a deeply set phillips screw that is removed to change the battery. I just spoke to a support person and asked "how do I change the battery?" He asked if there was a button or a screw, and said that it was changed to a screw because they'd had inadvertent releases of the battery on the older version. Our unit is new out of the box, but for a rechargeable battery that should last 4-5 years, I'd say go with the screw! (i.e. go with the MK2!)

I assume you refer to the remote control. In one of the sides of the remote you will find a hole that seems to be for a keychain ring. If you put put the remote horizontal and look at the side with the hole for the keychain, you will see a wider segment in the groove that separates the upper side of the lower side of the remote. Insert a screwdriver and rotate as if it were a screw that you want to unscrew. Both sides will separate and you will see the battery. After replacing the battery, just put one side on top of the other and press until you hear a click.Please, let me know if this is clear enough.Regrettably I can't send you a photo I assume you refer to the remote control.

take the battery cover off and press the reset button for 2 seconds. Maybe change the batteries as well.

Yes, it isn't really that difficult, but it is a little unique. You have to take out the key part, which is the same way you would change the battery. Then you will have just the old shell and the circuit board. There is a little hole in the front of the circuit board thing (in the yellowish part) and there are two holes about evenly spaced on the green part of the board. What I did was use a metal tooth cleaning device (like a pick) and pried the board out by first pulling on the front slot in the yellow part, then I used the hook of the pick to get into one of the round holes in the board itself and pulled it the rest of the way out. Use firm, but gentle pressure. I figure if I broke one hole I would still have the other one. Just be careful, take your time, and be gentle. I'll try to include a pic if possible.

Actually there is a way to replace batteries, to open unit locate 2 short screws at the "cork" end. Taking those out will allow you to remove brushed metal end. Then on the side is 4 spots of rubber which cover 4 longer screws. Now be careful you don't dump out contents but now the unit halves open up. You will see a battery pack that is connected to a printed circuit board. Either unsolder off the circuit board OR snip and strip the wires and attach new battery which if you search on Google the printed specification of the battery.. Simple

You need to remove the battery hinged door and insert the grip in place, to replace the battery. The little LCD display facing back.
