Note 2: Ta ≤ 50ºC: 80% RH max; Ta > 50ºC: Absolute humidity must be lower than the humidity of 85% RH at 50ºC
Note 3: Ta at -20ºC will be < 48 hrs at 70ºC will be <120 hrs when humidity is higher than 75%.
Note 4: Background color changes slightly depending on ambient temperature. This phenomenon is reversible.
Note 5: Ta ≤ 70ºC: 75% RH max; Ta > 70ºC: absolutely humidity must be lower than the humidity of 75% RH at 70ºC.
Note 6: Ta at -30ºC will be < 48 hrs, at 80ºC will be < 120 hrs when humidity is higher than 75%.
