01500 display readings are stuck for RH and dewpoint - all others are reading normally (or in the case of wind, consistently too low). RH is a constant 99% and dewpoint is always the same as outdoor temp. Can I assume the remedy for this is a reset? Take down outdoor unit (ugh - it's on a tall pole), make sure it's clean and take out batteries. Remove batteries and power from indoor readout. Wait a couple of minutes, then restore batteries to sensor, then readout and wait for them to communicate. What about the hard reset button -- press that, too as part of the process???
