.3 Notes on Use
(1) If you change the device address of the 3157 while using it, you should
immediately turn the power off and on again. If you do not do so, the address
change will not be registered by the bus, and problems will occur.
(2) Always be sure to secure the GP-IB cable to the 9518-02 unit by tightening up
the fixing screws provided.
(3) Program messages sent just after the power has been turned on are executed
after the self test has terminated.
(4) It is vital that the proper data format is used when inputting commands with
data values to the 3157 unit.
(5) For details of the various functions, refer to the instruction manual for the
3157 unit.

To prevent electrical shock, before adding or replacing the GP-IB
interface, check that the power for the unit is off and the power cord
and connectors are disconnected. [The fixing screws must be firmly
tightened or the input unit may not function up to specification, or may
even fail.]
To avoid the danger of electric shock, never operate the unit with a
GP-IB interface removed. If you should wish to use the unit after
removing an interface, fit a blank panel over the opening of the removed
unit.
