The tape drive temperature and humidity must be stabilized in the specified environment for at least 24 hours.
b
Temperature measurements are made in the tape path.
c
The tape drive is in its original shipping container. When the tape drive is moved from a cooler storage environment to a warmer operating
environment, it must acclimate in its packaging for 24 hours to prevent damage from condensation.
