signal.
When
synchronizing the AG-252
with
an external
signal,
apply the
sync
signal to this terminal.
The
terminal labeled 1 is the GND terminal.

Fuse
holder/Line voltage selector
The
fuse in the fuse holder is rated at 0.3A for
100/120V
type, or 0.2A for 220/240V type.
To
change the power voltage, unplug the power
cord
from
the power socket, then switch to the
required voltage. (See
"MAINTENANCE"
for
details.)

PRECAUTIONS
FOR USE
1.
Ensure
that 10Vrms or higher voltage is not
applied to the
OUTPUT
or
SYNC
terminals.
When
DC voltage is applied, make a connection
via
a capacitor.
2.
Use short connecting
leads.
Long shield wires
would
cause
amplitude characteristics to be
changed
by the capacity between shield wires.
Ordinary
leads,
if long, also tend to pick up
induced noise. Long leads of any type
cause
various
troubles.
3.
Connect the power cord after checking that the
power voltage to use is correct. The power
voltage should be
within
± 10% of the rated
voltage.
4.
Oscillation level may change soon after
turning
the
FREQ.
DIAL or pressing a
FREQ.

It is not an accident.
5.
Be sure to
press
one
FREQ.
RANGE
switch at
a
time. Note that the function will not operate
correctly if more than one
button
is pressed at
a
time or all the buttons are
