minimum after each step within the performance check where
applicable.
a. Position TI controls as listed in (1) through (3) below:
(1) VOLT SET switch (rear panel) to appropriate position (115 V ac).
(2) FREQ SET switch (rear panel) to 50/60.
(3) SELECTOR switch (rear panel) to 115 V ac.
b. Connect power cord from modulator AC OUTPUT (rear panel) to signal generator AC
INPUT (rear panel), using power cord supplied with TI.
d. Connect autotransformer to 115 V ac source and adjust for 115 V ac output.
e. Set both power switches to ON and allow approximately 30 minutes for equipment to
