3.5 Power-On Procedure
To power the MiniStat-Four on, connect the power cable to its power jack, then
plug the power supply into the AC wall outlet. The SYNC indicator should light. If
the link to the remote MiniStat-Four is still not operational, the SYNC indicator will
flash.
Check that after a few seconds (during which the MiniStat-Four performs
a self-test), the ERR indicator goes out.
