Any moulded mains connector that requires removal /replacement must be destroyed by removal of any fuse & fuse carrier
and disposed of immediately, as a plug with bared wires is hazardous if an engaged in live socket. Any re-wiring must be
carried out in accordance with the information detailed on this label.

WARNING: For continued fire protection, replace fuse only with the specific type and rating by

qualified personnel.    Disconnect the power cord before replacing fuse.

Cleaning the Cabinet

Disconnect the AC power cord before cleaning the instrument.

Use a soft cloth dampened in a solution of mild detergent and water. Do not spray cleaner directly onto the instrument, since it may
leak into the cabinet and cause damage.

Do not use chemicals containing benzing, benzne, toluene, xylene, acetone, or similar solvents.

GW assumes no responsibility for its product being used in a hazardous or dangerous manner

either alone or in conjunction with other equipment. High voltage and high pulse current used in

some instruments may be dangerous if misused.
