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: 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%.
