Installed new batteries, but need instruction to reset temperature readings

Try cleaning the outdoor thermometer transmitter unit by opening it up enough to spray compressed air (Ultra Duster or similar) on the temperature sensor. It fixed the hh.h error for me.

You probably need a new battery in you outdoor sensor.

INSTRUCTION MANUAL

I believe they ask you to press the reset button on the main unit first, but that may not be your problem. Double check the batteries to make sure they are installed correctly. If one of the batteries in the outdoor sending unit is in backwards, it will not send the outdoor data. On the indoor unit, there is typically one battery that is used for receiving the signal from the outdoor unit. If all of the batteries are in correctly but that one, you will see the display and the indoor temperature information, but the outdoor information will not be displayed. Also, make sure the units are close enough to transmit.

I have a BIOS wireless indoor/outdoor thermometer. The indoor base unit doesn't display the outdoor temperature - it is blank - however the other temperatures - humidity, indoor temp, etc., are displayed, What is the problem? We have misplaced the manual so we don't know what to do.

I changed the batteries on mine and it reset itself. That was easy.

often removing the batteries in both units will reset. replace batteries in indoor unit firs, let it settle down then insert batteries into outdoor unit. There may be a button on outdoor unit to initialise the connection.

Alternatively you might find the manual here or get the instructions from their support.
