When taking the device from low-temperature conditions into a warmer
environment or from high-temperature conditions into a cooler environment, allow
the device to acclimate to room temperature before turning on power.
When disconnecting a cable, pull on its connector or on its strain-relief loop, not
on the cable itself. As you pull out the connector, keep it evenly aligned to avoid
bending any connector pins. Also, before you connect a cable make sure both
connectors are correctly oriented and aligned.
