WARNING
HIGH VOLTAGES EXIST INSIDE THE CABINET ANY TIME THE
POWER CORD IS PLUGGED INTO A LIVE RECEPTACLE, AND THE
POWER SWITCH IS TURNED ON. ALWAYS TURN OFF THE POWER
SWITCH AND UNPLUG THE LINE CORD FROM THE RECEPTACLE
BEFORE ACCESSING THE INTERIOR OF THE
SPECTROPHOTOMETER. FAILURE TO OBSERVE THIS WARNING
MAY RESULT IN SERIOUS BURNS, INTERRUPTION OF HEART
RHYTHM, DISRUPTION OF THE NERVOUS SYSTEM, OR DEATH.
WARNING
WHEN IN OPERATION, CERTAIN INTERNAL COMPONENTS, SUCH
AS THE LAMP AND THE HEAT SINK ON THE MAIN CIRCUIT
BOARD, BECOME HOT AND MAY STILL BE HOT WHEN THE UNIT
IS OPENED FOR SERVICING. AVOID TOUCHING THESE AREAS.
FAILURE TO OBSERVE THIS WARNING MAY RESULT IN BURNS.
CAUTION
CIRCUIT BOARDS AND OTHER ELECTRONIC COMPONENTS ARE
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
BOARD BY ITS EDGES TO AVOID TOUCHING CIRCUIT TRACES OR
DEVICES WITH BARE HANDS OR FINGERS.
CAUTION
MOST ASSEMBLIES ARE MOUNTED TO THE PLASTIC HOUSING
WITH THREAD-FORMING SCREWS. ALWAYS BE CAREFUL TO
NOT OVER TIGHTEN THESE SCREWS OR THEY WILL STRIP OUT
THE HOLE. THIS WILL DESTROY THE ABILITY OF THE SCREW
TO PROPERLY SECURE THE ASSEMBLY.
