Hazmat,
I'm not at home right now to check, but from memory:
If you press and hold the button in between the up and down arrow for about 5 seconds, you will enter the setup mode - same place you set the time - then press the button again a few times and it will display the water temp.
If you have a newer model like I do, it won't actually tell you what it thinks the salt reading is. It will just say salt ok, salt high, or salt low. I'm pretty sure they changed this because of all the people calling them saying the salt reading doesn't match the pool store, test strip, etc.

They are very nice and polite. However, I'll go out on a limb and make a prediction: Your first call will result in someone telling you to "re-calibrate" the unit (really just means to try a different correction factor). If you call back and tell them that that didn't work, they will want to replace the lcd screen, either under warranty or you buy a new one if the warranty is expired (the LCD screen is actually on a circuit board that is a lot more than just a display). That was where I gave up after changing the board and still having the same intermittent high salt light.
When I called, like I said, they were very polite. But my impression of their troubleshooting was not so great. Basically they have a known issue that they first try to resolve with the calibration, and second with a part changeout. Also, from what I have read, all of the R&D, and thus, detailed knowledge of how they function, is in Austrailia. So again, I'll give them kudos all day long on "attitude", but they fell short in the "solved my problem" category.
If I had it to do over again, I would do EXACTLY the same thing. I have learned to accept that the high salt light will turn on and turn off - it means nothing to me as long as the cloud is in the cell and my FC stays where I need it. So far this works, and the price of the unit compared to others make it something I'll live with.
Hopefully I'm in the minority....
When yours says over salt, check on the temp and let us know.....
