It means OverFLow - the display unit can read from -39.8°F to 139.8 °F and it is getting a signal from the sending unit that is lower than -39.8 or higher than 139.8. This happens when the sending unit goes haywire (or, not likely, when temperature out doors is REALLY lower or higher than the range). Replace the sending unit. If you really like the product, I suggest you buy another of the same model. It will come with a new sending unit and that will be read by both of the displays if they are within 80 ft of the sending unit. Good luck.

when you have an expensive watch, take it to a jeweler or, to a pawn shop. Many pawn shops change batteries, and are cheaper than jewelers. Always ask for price first.

try holding down on one of the set pins for 2 to 5 seconds, then let off. some watches wont reset unless you do that.

You may download a copy of the manual at http://www.lacrossetechnology.com/9047itc/manual.pdf

It's a PDF file so your viewer should be able to magnify it to just about any size you want.

Make sure they are both set to the same channel (normally channel 1) put them next to each other then press reset on the temperature unit only.

If you have not talked to La Cross and if you continue to have the problem, most likely it may be a signal problem. I had a similar
problem with an earlier model and found that it only worked on
the west facing wall as the signal is coming from WWVB which is the NISTtime signal radio station near Fort Collins, Colorado. Get a fresh battery, reset the clock, put it in a west facing window and leave it overnight. If it doesn't work, contact La Cross as above post.

Is the picture the type of clock your referring to? If so you cant set the time zone on that type of clock. You can change the time though.

I'm not totally sure what you mean by "reset the time" because the unit normally sets the time automatically from the WWVB radio time signal. If you want to do it manually, this is what the Instruction Manual (PDF format) says:

MANUAL TIME SETTING

In case the atomic clock is not able to detect the WWVB-signal (disturbances, transmitting distance, etc.), the time can be manually set. The clock will then work as a normal Quartz clock.

  1. The hour digits will start flashing in the upper LCD.
  2. Select the desired hours by pressing and releasing the + key.
  3. Press and release the SET key to advance to the minutes setting.
  4. Now the minute digits will start flashing.
  5. Select the desired minutes by pressing and releasing the + key. If the + key is held, the units
    will increase by 5.
  6. Press and release the SET key to confirm the Time setting and continue to the Year setting.

these really aren't atomic clocks and are set at the factory. It receives, it's LF signal out of Colorado and should correct itself. If not contact the manufacturer.

Based on a different, but similar, LaCrosse model (the WS-8611), it would appear to be an OverFlow indication, meaning that it's out of range. Here's a quote from that unit's manual:

SPECIFICATIONS:
Temperature measuring range:
Indoor : 14.2F to +139.8F with 0.2F resolution
(-9.9C to +59.9C with 0.1C resolution)
("OF.L" displayed if outside this range)
Outdoor : -39.8F to +139.8F with 0.2F resolution
(-39.9C to +59.9C with 0.1C resolution
("OF.L" displayed if outside this range)

It is likely that their convention remains the same across models, but I don't work for them, so I can't guarantee it.

I think we're not talking about a WT-3101. What model is YOUR clock?

This site lists several including some desk models on two pages and each has unique downloadable instructions.
