• Before beginning installation, switch off the power to the
instrument and connected peripherals, and unplug them from
the power outlet. Then remove all cables connecting the
instrument to other devices. (Leaving the power cord connected
while working can result in electric shock. Leaving other cables
connected can interfere with work.) Installation or removal of any
devices should be started ONLY after the instrument (and the
optional hardware) returns to normal room temperature.
