Note 4, 5

Note 4,6

Note 4: Background color changes slightly depending on ambient temperature. This phenomenon is reversible.

Note 5: Ta ≤ 70ºC: 75 RH max; Ta > 70ºC: absolute 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%.
