HIGH VOLTAGES EXIST INSIDE THE CABINET ANY TIME THE
POWER CORD IS PLUGGED INTO A LIVE RECEPTACLE, AND THE
POWER SWITCH IS TURNED ON. THE POWER SWITCH SHOULD
ALWAYS BE TURNED OFF AND THE LINE CORD UNPLUGGED
FROM THE RECEPTACLE BEFORE ACCESSING THE INTERIOR OF
THE SPECTROPHOTOMETER. HOWEVER, THE FILTER WHEEL
ALIGNMENT PROCEDURE REQUIRES THE OPERATOR TO HAVE
POWER TURNED ON WHILE ACCESSING THE INTERIOR OF THE
CABINET. THEREFORE, IT IS VERY IMPORTANT THAT ONLY
TRAINED TECHNICIANS, AWARE OF THE DANGERS AND PROPER
SAFETY PRECAUTIONS,
PROCEDURE. ALWAYS EXERCISE EXTREME CARE AND BE
AWARE THAT LIVE POWER EXISTS AT VARIOUS POINTS ON THE
INTERNAL COMPONENTS.

AS THE LAMP AND THE HEAT SINK ON THE MAIN CIRCUIT
BOARD, BECOME HOT.
FAILURE TO OBSERVE THIS WARNING MAY RESULT IN BURNS.

SUBJECT TO DAMAGE FROM ELECTROSTATIC DISCHARGE. TO
PREVENT SUCH DAMAGE, USE A WRIST OR HEEL GROUNDING
STRAP. GROUND TOOLS THROUGH A CONDUCTIVE MAT
BEFORE TOUCHING ANY POTENTIALLY STATIC-SENSITIVE
ASSEMBLIES OR DEVICES. WHEN HANDLING PRINTED CIRCUIT
BOARDS OR OTHER ELECTRONIC ASSEMBLIES, HOLD THE
