INSTRUMENT SERIAL NUMBERS
Each instrument has a serial number on a panel insert, tag,
or stamped on the chassis. The first number or letter
designates the country of manufacture. The last five digits
of the serial number are assigned sequentially and are
unique to each instrument. Those manufactured in the
United States have six unique digits. The country of
manufacture is identified as follows:
BOO0000 Tektronix, Inc., Beaverton, Oregon, USA
100000 Tektronix Guernsey, Ltd., Channel Islands
200000 Tektronix United Kingdom, Ltd., London
300000 SonyJTektronix,Japan

Power Source
This product is intended to operate from a power module
connected to
a power source that will not apply more than
250 volts rms between the supply conductors or between
either supply conductor and ground. A protective ground
connectionby way of the groundingconductor in the power
cord is essential for safe operation.
Grounding the Product
This product is grounded through the grounding conductor
of the power module power cord. To avoid electricalshock,
plug the power cord into a properly wired receptaclebefore
connecting to the product input or output terminals. A pro-
tective groundconnection by way of the groundingconduc-
tor in the power module power cord is essential for safe
operation.
Danger Arising From Loss of Ground
Upon loss of the protective-groundconnection, all accessi-
ble conductiveparts (including knobs and controls that may
appear to
be insulating)can render an electric shock.
cessible as one reads the marking.
Use the Proper Fuse
SYMBOLS
In This Manual
To avoid fire hazard, use only the fuse of correct type, volt-
age rating and current rating as specified in the parts list for
your product.
Refer fuse replacement to qualified service personnel.
This symbol indicteswhere applicablecaution-
ary or other informationis to be found.
Do Not Operate in Explosive Atmospheres
