TSG 95 Service Manual
propriate instrument (such as the Tektronix VM700A, option 40/41) to
measure the tone level, and adjust it to within 0.25 dBu of its “name” with
the
A
and
"
keys. The range of adjustment is Low 00 to Hgh (high) 99.
CAUTION.
Changing the “CAL TONE LV#” settings (menu items 7, 9, B, and D)
will affect the audio tone amplitude and can give inaccurate results unless prop-
er equipment and procedures are used. The audio adjustment procedure begins
on page 4–29 (in the Performance Verification and Adjustment section) of this
manual. A FACTORY RESET will NOT restore these settings to their original
values. It is a good idea, then, to record the original settings before changing a
tone level from its as-manufactured value.
To ensure your ability to restore the original factory tone calibration settings
in the case of inadvertent changes, please record the following information:
TSG 95 serial number:
Original –10 dB setting: (e.g., Low 17)
Also take the time to record the settings for the remaining tone levels in
menu (list) items 9, B (11), and D (13).
