•Adjustments described in this manual are performed with power supplied to the instrument while protective covers are removed. Be aware that energy at many points, if contacted, result in personal injury.

•Do not install substitute parts or perform any unauthorized modification to the instrument.

•Be aware that capacitors inside the instrument may still be charged even if the instrument has been connected from its source of supply.

:$ 5 1 , 1 * To avoid hazardous electrical shock, do not operate the instrument if there are any signs of damage to any portion of the outer enclosure (covers, panels, and so on).

:$ 5 1 , 1 * To avoid the possibility of injury or death, you must observe the following precautions before powering on the instrument.

–If this instrument is to be energized via an autotransformer for voltage reduction, ensure that the Common terminal connects to the earthed pole of the power source.

–Insert the power cable plug only into a socket outlet provided with a protective earth contact. Do not negate this protective action by the using an extension cord without a protective conductor.

–Before switching on the instrument, the protective earth terminal of the instrument must be connected to a protective conductor. You can do this by using the power cord supplied with the instrument.

–It is prohibited to interrupt the protective earth connection intentionally.
