(20) BFO-RF LEVEL control fully cw.
(21) HI LVL-Vx100-NORM switch to HI LVL.
(22) AUTO-ZERO-OFF-BATT switch to AUTO ZERO.
(23) PWR-OFF-BATT switch to OFF.
b. If FREQ ERROR, DEVIATION, and MM-100E meters do not indicate zero, adjust
to zero with adjustment screw located below each meter face.
c. Connect TI to autotransformer. Connect autotransformer to a 115 V ac source and
adjust for 115 V output.
d. Set PWR OFF BATT switch to PWR and allow at least 15 minutes for warm-up.
8. Frequency Accuracy
a. Performance Check
(1) Connect frequency counter to TI 10 MHz REF OUT.
(2) Adjust REF CAL (front panel) until frequency counter indicates between
9,999,995 and 10,000,005 Hz. If indication cannot be obtained, perform b (1) and (2) below.
(3) Connect TRANS-RCVR output to frequency counter.
(4) Set FREQUENCY MHz switches to the first setting in table 4.
Frequency
counter will indicate within specifications listed in table 4.
(5) Repeat technique of (4) above for settings and indications listed in table 4.
