INSTRUMENT SERIAL NUMBERS
Each instrument has a serial number on a parcel 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 :
8000000 Tektronix, Inc ., Beaverton, Oregon, USA
100000 Tektronix Guernsey, Ltd ., Channel Islands
200000 Tektronix United Kingdom, Ltd ., London

7810 Instruction
The following general safety information applies to all operators and service personnel. Specific warnings and cautions
will be found throughout the manual where they apply and should be followed in each instance .
WARNING statements identify conditions or practices which could result in personal injury or loss of life .
CAUTION statements identify conditions or practices which could result in damage to the equipment or other property.
WARNING
GROUND THE INSTRUMENT
To reduce electrical-shock hazard, the mainframe (oscilloscope) chassis must be properly grounded. Refer to
the mainframe manual for grounding information .
DO NOT REMOVE INSTRUMENT COVERS
To avoid electric-shock hazard, operating personnel must not remove the protective instrument covers .
Component replacement and internal adjustments must be made by qualified service personnel only .
DO NOT OPERATE IN EXPLOSIVE ATMOSPHERE
To avoid explosion, do not operate this instrument in an explosive atmosphere unless it has been certified for
such operation.
CAUTION
PREVENT INSTRUMENT DAMAGE
Plug-in units should not be installed or removed without first turning the instrument power off, to prevent
instrument damage .
7810 Instruction
FOR QUALIFIED SERVICE PERSONNEL ONLY
Refer also to the preceeding Operators Safety Summary
The following are safety precautions which appear in the servicing information sections of this manual . This Servicing
Safety Summary is in addition to the Operators Safety Summary given previously .
WARNING
DO NOT SERVICE ALONE
Do not attempt internal service or adjustment unless another person, capable of rendering first aid and
resuscitation, is present.
DISCONNECT INSTRUMENT POWER
To avoid electric-shock, disconnect the instrument from the power source before removing protective panels,
soldering, or rep/acing components .
SILICONE GREASE HANDLING
Handle silicone grease with care . Avoid getting the silicone grease In your eyes. Wash hands thoroughly after
use .
AVOID EXCESSIVE MOISTURE
Circuit boards and components must be dry before applying power to prevent damage from electrical arcing.
EXERCISE CARE WHEN CHECKING DIODES
When checking diodes, do not use an ohm-meter scale that has a high internal current, since high currents
may damage the diodes under test.
EXERCISE CARE WHEN SOLDERING ON MULTI-LAYER BOARDS
All but the readout circuit board in the instrument are multi-layer type boards with a conductive path
laminated between the top and bottom board layers. All soldering on these boards should be done with
extreme care to prevent breaking the connections to this center conductor. Only experienced maintenance
personnel should attempt repair of these boards.
USE PROPER CLEANING AGENTS
Avoid the use of chemical cleaning agents which might damage the plastics used in this instrument. Use a
non-residue type of cleaner, preferably isopropyl alcoho% totally denatured ethyl alcohol, or Freon TF. Before
using any other type of cleaner, consult your Tektronix Service Center or representative.
DO NOT USE PIN SOCKETS FOR CONNECTION POINTS
The spring tension of the pin sockets ensures a good connection between the circuit board and the pin . This
spring tension can be destroyed by using the pin sockets as a connecting point for spring-loaded probe tips,
alligator clips, etc.
