is flush with the outside of the case. (When fully seated, the channel
will project slightly into the inside of the case.)

The HOBO U30 Station should power up and connect to HOBOlink.com. If
you wish to start a new launch after the assembly is complete, use
HOBOlink to relaunch the station. Under Launch Configuration in
HOBOlink.com, select Force Relaunch on Next Connection.
Also be sure to close the door and snap the hinges shut on the HOBO U30
Station case when you are finished. Consider using padlocks to secure the
case.
If you are deploying the HOBO U30 Remote Monitoring System in a
location where rodents are present, it is recommended that you protect all
exposed cables and wires with conduit to prevent rodents from chewing the
cables.
