How to adjust the altitude in this weather station? Sharper Image Weather Station & Atomic Clock EW400

Impossible to answer. On WHAT!!!

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

Google

make model manual

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

Select "change time zone" and press to remove the "automatically adjust clock for daylight saving time" symbol to automatically update the clock when daylight saving time is applied.

It's depends on where you are. For instance, where there is no time signal radio station, your (radio-controlled) watch can't turn itself (adjusted to atomic time).

Setting and Calibrating Your Altitude
1. Press MODE until CAL is shown.
2. Hold SET to begin the calibration.
3. Press START/SPLIT (+) until HOME ALTI is displayed (or choose WEATHER when calibrating weather).
4. Press MODE (NEXT) to begin the setting process.
5. Press START/SPLIT (+) or STOP/RESET (-) to increase or decrease setting values.
6. Set the value to your current elevation.
7. Press MODE (NEXT) to advance to the next setting option.
8. Press SET (DONE) to finish.
9. To complete calibration for the REFRENCE HOME altitude (or WEATHER setting), press and hold STOP/RESET until watch beeps.

Repeat this procedure for WEATHER, making sure to choose the proper weather condition on the WS4 that matches your current weather.

Once these two variables are calibrated, your WS4 will be ready to go, providing you with accurate altitude, pressure, and weather forecast information at your fingertips. Enjoy.

how do I set the functions of M1600 swivel Worldtime clock

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.
