For Christmas last year Jered & Aimee bought us an Oregon Scientific wireless indoor/outdoor thermometer - Model# RAR381.  It’s an excellent little thermometer that Amy and I keep on our kitchen counter and check all the time.

In the middle of the first night we had the thing turned on though, it started beeping & beeping & beeping. I clammored down the stairs in my half-awake stupor and pulled the batteries out. The next morning I put the batteries back in and made sure there were no alarms set and that all the sound icons were off. The next night though the very same thing happened. I turned on the lights and saw a flashing snowflake symbol above the temperature.  “Ah”, I thought, “Freeze Alarm”.  Eventually I figured out the solution to turning off the freeze alarm and didn’t think about it again.

Well after about a year, the 2 AAA batteries died and it was time to put in new ones.  When I did, I noticed that it was not connecting to the outdoor sensor so I switched it to channel 1.  Last night I was rudely awoken again by beeping. I knew it was the freeze alarm but had no idea how to turn it OFF.

After some Googling, I found the solution:

To deactivate the freeze alarm on the RAR381/681 and the RMR382/682, you will need to set the remote sensor to Channel 2 or 3.  The freeze alarm does not work on channel 2 or 3.

1. Remove the cover from the remote sensor and locate the channel switch.
2. Slide the channel switch to channel 2 or 3.
3. Depress the reset button with a paperclip or pen (see item 5 on the figure below).
4. Slide the battery cover back on.
5. Enjoy peaceful, alarmless sleep…at least until the real alarm goes off.

I know this is more of a personal sticky-note than a blog post, but if I can’t easily Google the answer to a problem I’m having, I tend to blog about it - that way I can find it later.
