push-
switches in.
Adjust the CENTERING
controls until the spot comes
in the center of the small circle.
Adjust the BRIGHT control (ROO2) on the rear panel
until the brightness becomes dark a little.
Adjust the FOCUS
control so that the spot may be-
come smaller and circular.
. Turn the SCOPE
LEVEL control to the FCW.
. Connect a 150 mV, 1 kHz signal to the AUX
INPUTS
R jack and adjust R928 (H. GAIN) until the horizontal
deflection is around 3 cm.
In turn, connect
the same
signal to the L jack and
similarly,
adjust
R927
(V. GAIN)
until the vertical
deflection is around 3 cm.
Set the CENTERING
control to the 12-0'clock posi-
tion
and adjust
R925
(H. CENTER)
until the spot
comes in the horizontal deflection center.
Similarly, adjust
R926
(V. CENTER)
until the spot
comes in the vertica! deflection center.

6.1 AM TUNING DISPLAY ADJUSTMENT
1. Depress the SCOPE
DISPLAY
ON and TUNING
push-
switches. Set the SELECTOR
switch to the AM position.

30% mod.) to the FM ANTENNA
terminals and adjust
R278 so that the spot does not frame out.
6.3 FM MULTIPATH
DISPLAY ADJUSTMENT
1. Adjust R280 to obtain full deflection of the trace within
both
side
marks,
applying
FM
signal
(1 kuV,
400 Hz,
100% mod.) to the FM ANTENNA terminals.
7. VOLTAGE CONVERSION
FOR EUROPEAN MODEL
The European version of the Model 2600 is equipped with
a universal
power
transformer
that may
be adjusted
to
operate
at 110 V, 120 V, 220 V, or 240 V AC at 50 to
60 Hz. To convert
the unit to a different power source
voltage, reposition conversion plug at shown in Figure 1.
CAUTION:
DISCONNECT
POWER
SUPPLY
CORD
FROM
AC OUTLET
BEFORE
CONVERT-
ING VOLTAGE.
