Recently purchased 5 in 1 Acurite Color Weather Display that will not allow Barometric Pressure calibration on indoor display. The barometric pressure (BP) is off low nearly 2 points (28.88 vs 30.12). Tried the "Press and Hold the + and * and - Simultaneously", but it won't go past the Weather Select screen item to allow any BP change. The display always says rain is forecast because of the low BP. Tried calling problem in, but after 1 hour wait I hung up. Will return to Amazon if not resolved.
