NOTE
On early boards TP3 did not exist. If TP3 is nonexistent attach
(4) Route wire through hole in RF lid and place RF lid back in position. Secure lid
with two screws.
(5) Connect oscilloscope and multimeter to extension wire. Set multimeter for DC
measurement.
(6) Press TI [RX TEST].
(7) Slowly advance L1 adjuster (fig. 4), observing waveform on oscilloscope.
Frequency should decrease and finally become zero as A10/1 locks to 90 MHz 3rd local
(9) Continue advancing L1 adjuster (fig. 4) until lock is lost and multimeter
indication increases further.
(10) Slowly unscrew L1 adjuster (fig. 4), observing oscilloscope waveform frequency
decreasing, until lock is regained when frequency becomes zero.
(12) Adjust L1 (fig. 4) for a multimeter indication of (V1 +V2). Oscillator should
lock to 90 MHz, in the middle of its capture range.
(13) Remove TI RF lid and remove extension wire.
(14) Replace and secure TI RF lid.
(15) Press TI [MEM] key and recall memory 01.
