How do you replace batteries in freshair remote control . i cant get the back off the remote control.

For the Fresh Air 2.0 or 2.1 remote, its oval shaped.

1. Hold the remote so that that the power button is facing up.

2. Then flip the remote in your hand so you can see the back side.

3. Then with your other hand, side your index finger from the top down the back side of the remote until you finger nail catches the a slot (about an inch from the top of the remote). Right below that slot, is a plastic tab that secures the battery cover. Using your finger nail, pull that tab down about 1/16" away from the remote to unlatch the cover.

4. Lift the cover off the remote, and you should see 2 AAA batteries. Remove the old batteries and replace with 2 new batteries.

5. Align the two tabs on the battery cover into slots on the back of the remote.

6. Gently press the back cover and the latching tab should shap into the remote.

Hope this helps.
