1.11 Notes on Use
(1)
Before starting the measurement
When turning on the power, don’t connect DUT.
Before starting the measurement, check to see the output power level.
(2)
Removing of case
Do not open the case to one except service man of our company.
The R3765/67G series has a high temperature part and a high pressure part.
(3)
When abnormality occurs
When smoke rises from the R3765/67G series, smell nastily, or rear unusual sound feel,
turn off the power switch. Pull out power cable from the outlet. And contact to our company.
The address and the telephone number of our company are in the end of this manual.
(4)
Warm up
After the R3765/67G series temperature has reached the room temperature level, turn the
power switch ON and warm it up for 30 minutes.
(5)
Electromagnetic interference.
High frequency noise of the small power is generated at the R3765/67G series use.
Therefore, electromagnetic interference is generated to the television or the radio by an im-
proper installation and use of the R3765/67G series.
If the power of the R3765/67G series is turned off, and the electromagnetic interference is
reduced, then the R3765/67G series is the cause it.
Prevent electromagnetic interference by the following procedure.
•
Change the direction of antenna of the television or the radio.
•
Place the R3765/67G series the other side of the television or the radio.
•
Place the R3765/67G series away from the television or the radio.
•
Use another line of power source for the television or the radio than the R3765/67G
series.

Prevention of Elecrostatic Buildup
To prevent damages to semiconductor parts from electrostatic discharge (ESD), the pre-
cautions shown below should be taken. We recommend that two or more measures be
combined to provide adequate protection from ESD. (Static electricity can easily be built up
when a person moves or an insulator is rubbed.)
Countermeasure example
Human body:
Use of a wrist strap (see Figure 1-2).
Floor in the work area:
Installation of a conductive mat, the use of conductive shoes,
and grounding (see Figure 1-3).
Benchboard:
Installation of a conductive mat and grounding (see Figure 1-4).
