(3) Repeat technique of (2) above for switch settings listed in table 6. If measuring
receiver does not indicate within limits specified, perform b below.
b. Adjustments
(1) Set RF OUTPUT switch to 250 KUV and adjust LO-HI RF SET TO LINE
control for a 250 mV indication on measuring receiver.
NOTE
When TI protective cover is removed to make adjustments, do
not change setting of 115 230 LINE VOLTAGE SELECTOR
switch (located on bottom front center).
(2) Adjust R1 ((HI-RF METER CAL) located on lower right side) for a 0.55 or a red-
line indication on IF UV RF SET TO LINE meter (R).
