The book for that unit is here: http://www.acurite.com/kbase/search/query/00754/

Try taking the inside unit outside as close to the transmitting unit as possible for three minutes. The signal might lock on to the setting you want to receive.

I have a acu-rite weather station and it keeps blinking even after changing batteries, is it garbage now or can it be saved

The main thing with this unit is to put the batteries in the transmitter first, then in the base receiving unit. Then you can't really make any setting changes until the unit figures out the correct time through the radio signals it receives from Colorado, or wherever they come from.

There is no way to turn off beeping. From this site: http://www.chaneyinstruments.com/FAQ.aspx
found solution - search for - Q: My wireless weather station periodically beeps, why?
A: .. unit's ability to detect a foreign radio frequency of another wireless unit when that unit transmits a signal. .. 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.

There is no way to turn off beeping, d/s designers forgot. I had the same problem, another external temp gauge showed up on the other channel, so my neighbor or someone is using the similar unit. MY SOLUTION: opened back of case and cut black wire to piezo speaker (at base if rear cover opposite side of stand-up prop) that creates beep. Don't use any sound features, ALL good now.

found solution - 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 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:
