My weather station will not show the outside temp.

Impossible to answer. On WHAT!!!

All questions need FULL 'make model (what it is)'.

Normally on that type of device you have to set the YEAR, and then the MONTH like on my Weather Station Indoor Unit..

I am not familiar with garmin, but you could check the settings, if it is like a computer you may have to check or uncheck show weather conditions.

This is for Ultronic LCD clock/weather gadget.

keywords (from display)
Ultronic forecast week day humidity temperature trend comfort level
- DOWN = toggles F/C temp
- UP = toggles alarm
- MODE = selects date/time display
- hold down MODE to enter "set" mode for data currently displayed
- use momentary MODE to choose target item
- use UP/DOWN to change item

I had the exact same problem, and found the answer on the Chaney Instrument FAQ page. There's no real solution, but here is the explanation:
Q: My wireless weather station periodically beeps, why?
A: Make sure that any alert and/or alarm features are deactivated first. Constant, sporadic beeping is generally due to the unit’s ability to detect a foreign radio frequency of another wireless unit when that unit transmits a signal. Wireless devices that may cause beeping but are not limited to these devices are; scanners; computers w/wireless keyboard/mouse; or other wireless weather instruments. Essentially, any wireless devices transmitting on a radio frequency have the potential to interfere with each other. Limit the amount of wireless devices to lesson the chance of interference. When beeping occurs, one device will need to be deactivated.

I solved it by my self by a try and error procedure

The watch will show body temperature until you remove it from your wrist and leave it in the open air for a few hours whilst it acclimatises and then reads the ambient temp, not your body temp.
This renders the thermo pretty useless.

Solved it! La Crosse let you download manuals from their website.

My 1510-IT came with a faulty battery cover top for the rain guage. There should be a metallic clip mounted to the cover to tie the 2 batteries together electrically. Mine had nothing there. I soldered a wire between the 2 batteries and used some cardboard under the cover to make sure the batteries were pushed down into their holder. Problem solved!

I can't imagine this is systemic but it happened to me.

hi...

press the T button until the crystal is activated.
press the middle of the glass until the time format appears (24hb Cm appears)
hold the T button for 5secs (SYNCHro appears)
move the hands until they are at 12 o'clock. ( + button moves the minute hand. - button moves the hour hand)
press the T button to set.

digital and analogue time are synchronised

Dreco,
I was changing my battery and ran into a small problem, too. I know where one spring goes, but I have another similar spring that may have fallen out of the watch (I was working on another different watch before, so I'm not sure if the 2nd spring belongs in the watch). One spring contacts the small speaker on the metal cover and will not affect the LCD display.

How many springs do you see in yours, if any?
