Even with brand new batteries inserted into the Reciever, I still can't get an outdoor temperature. Why ?

Hello.

Make sure the batteries' voltage are exactly the same as the batteries you replaced. If you are still having the same issue even if the batteries' voltage are the same, update me with the brand and model of your machine.

Read this procedure to possibly fix the remote:

They also sell replacement remotes.

Zoom in on the picture of the original remote provided on the site (or look at your own) and get the actual remote model number.
or check eBay: search for "(model of the device or the remote) remotes", check the 'include description' box. Usually cheaper than the vendors.

you need to take the batteries out of your clock/themometer, wait a couple of minutes then put the batteries back in, the reciever should find your transmitter and indicate the outside temperature, if this is a clock you can set it. If its a "atomic" clock you can let it set itself

are you sure the batteries are ok? even new batteries can sometimes be dead,

Seems to be a consistent problem with Skyscan. I have the 88800 model and my outdoor transmitter isn't transmitting the temperature either. We've replaced the batteries in both the transmitter and clock and nothing for outdoor temp. It's only been used for 9 months.

To get the outside temperature working again, open the outdoor sensor box carefully loosening the one screw with a screwdriver, insert 3 brand new AA batteries, check phone for outside temperature. If not showing on the phone display, try changing the 'channel' setting, just above the batteries. Be careful not to break the tiny switch. Gently use a smaller flathead screwdriver, if needed. There are 3 settings. Mine worked fine on the first setting. If it is showing on the phone set screens, then, carefully screw the lid back on to the sensor box, and re-insert into the sensor wall holder. I keep mine in a plastic bag on a shelf outside, away from sun, so I can get a true reading day or night. It is always a bit warmer in the sunlight than the true outdoor air temperature. Enjoy

if you have changed batteries you need to re-since, there should be a little red button on bottom and a button on reciever.

basically all the things you went through for the initial setup

that maybe the case..you could put a shielded barrier(copper coated poly) between them.sounds like it's a little too sensitive

I have the same problem on the same receiver. I split my cable and plugged one side directly into the system, and the other I used a 300/70 ohme converter to plug into the fm antenna side. This helped to get stereo on local stations. I think I am going to have ot go for an outdoor antenna to get anything more.
