Tektronix 070-5992-05 Installation, 760A / 760D / 760N 33, Figure 31: 760A / 760D / 760N jumper locations for input and display orientation selections

Installation
760A / 760D / 760N 3–3
graticule supplied with the instrument. Detailed instructions for removing the
bezel can be found under the Mechanical Assembly/Disassembly topic in
SECTION 4, MAINTENANCE. Then move two jumpers on the Main circuit board,
J273 and J373, to the position labeled X–Y (pins 2 & 3) in Figure 3–1.
Also for X–Y display orientation, rotate P886 (on back of A3, Main board) so
pins 1 and 2 of the connector mate with pins 2 and 1 of J886 (connect back-
ward). Repeat with P862/J862. Remember to return P886 and P862 to their
normal (pin 1 to pin 1) positions for Sound Stage display orientation. This
provides correct phasing for both display orientations.
