Where to put outside remote

1. Take the cover off the back of the remote sensor.
2. Set the chanel to ch.1. (I tried all three but only ch.1 worked for me).
3. Use a stick, needle, what ever you can (but you need two) and hold down the reset button on both the sensor and the clock at the same time.)

If done right, it should only take a few seconds to start.
The outside temp is delayed at first. Be patient.

I have the same unit (IWA-80055) and after not finding anything helpful on the net, I just messed with it until I got it fixed. Here's what to do:

1. Take the cover off the back of the remote sensor.

2. Set the chanel to ch.1. (I tried all three but only ch.1 worked for me).

3. Use several tools. (i.e. a stick, needle, what ever you can but you need two) and hold down the reset button on both the sensor and the clock. (at the same time.)

If done right, it should only take a few seconds to start.

The outside temp is delayed at first. Be patient.

Pull the batteries out of the clock, wait a minute, and then put them back in. That will reset the link between the two. The temperature should be OK in just a few minutes. The clock will read the wrong time and date until it resets during the night. The next day, all will be well.

Have you got this solved?

Did you put two AAA batteries in the remote? Use a small phillips to take the cover off of it. Then hold channel on the main unit for three seconds to synch it with the remote.

Once the batteries are installed in the remote the temp will appear in the LED screen. Now you are ready to link signals between the main unit and the remote. Simply remove one of the two triple A batteries from the main unit and then replace. You should then see what appears to be a flashing object shaped like a kite with a tail while the two units link up. Then you should see the temp reading at the remote appear in the LED readout at the main unit. By the way there is also a very small reset at the top of the switches on the back of the main unit that can be depressed with a SMALL pointed object like a scissor point or safety pin point.

I've had a similar problem with another model, an Oregon Scientific Model IWA-80055 Wireless Thermo Clock, in which when I replaced the batteries in the remote sensor, the clock would not read the temperature from the remote sensor.
I found it fairly consistent to solve this by taking a battery out of place in the clock and putting it back in.  Unfortunately this also messed up the clock's time and date.  This is also in the instructions catalogue for the device, check and see if yours gives a similar solution.

I have the same problem with mine. The outside temp displays OK for a while, then it displays two dashs. I unplug the main unit from the wall until the outside temp comes back. I then plug it back in and it works OK. I found that if the remote sensor is located more than 40 ft from the main unit and there are a couple of walls between the two, the outside temp fails more often. I have noticed that putting my wireless phone in it's charging craddle can cause the radio or nature sounds to turn on. I moved the main unit further away from the phone and that cured the problem. Sometimes it will do this if the humidity is low and I build up a static charge and then touch the unit.
