over, or stressed. Pay particular attention to
condition of cords and cables at plugs, and the
point where they exit from the AR-1215 or AR-
2306. To prevent risk of fi re or injury, damaged
cords and cables should be replaced immedi-
ately.
5. Clean the AR-1215 or AR-2306 with a damp cloth
only. Do not use solvents or abrasive cleaners.
Never pour any liquid on or into the unit.
6. When left unused for a long period of time, the
power cord of the AR-1215 or AR-2306 should
be unplugged from the outlet.
7. The AR-1215 or AR-2306 should be serviced
by qualifi ed service personnel when:
a. The power supply cord or the plug has been
frayed, kinked, or cut.
b. Objects have fallen or liquid has spilled into
the unit.
c. The AR-1215 or AR-2306 has been exposed to
rain or other moisture.
d. The AR-1215 or AR-2306 does not appear to
operate normally or exhibits a marked change
in performance.
e. The AR-1215 or AR-2306 has been dropped,
or the enclosure damaged.
8. The AR-1215 or AR-2306 requires that a safety
ground be present for proper operation. Any
attempt to operate the AR-1215 or AR-2306
without a safety ground is considered improper
operation and could invalidate the warranty.
9. There are no user serviceable parts in the AR-
1215 or AR-2306. Refer servicing to qualifi ed
service personnel only.

NOTE: The three models in the AR-Series differ in
their nominal AC output voltages. Model AR-1215
produces 120 VAC. Model AR-1215J produces
either 100 or 120 VAC. Model AR-2306 produces
either 220, 230, or 240 VAC.
Where differences exist between models, informa-
tion applicable to the AR-2306 is shown in the text of
this manual in brackets [ ].
FIRST: SELECT THE CORRECT VOLT-
AGE!
Before using your Voltage Regulator, be sure that if
there is an output voltage switch on the rear panel
(just above the cord, on Models AR-1215J and
AR-2306 only), it is correctly set for the AC voltage
required by your equipment. Each item of equipment
that you intend to power with the Voltage Regula-
tor should have its required voltage indicated on it,
usually on the rear near the cord. If in doubt, consult
your dealer.
Furman Voltage Regulators are intended to pro-
tect sensitive electronic equipment from problems
caused by AC line voltage irregularities—brownouts
or overvoltages that can cause audio tonal changes,
digital equipment malfunction (such as loss of MIDI
programs or other data), or, in extreme cases,
permanent damage. They accept input voltages
over a wide AC voltage range (see table on page 2)
and convert them to a steady, stable output at the
desired standard voltage, plus or minus fi ve [ten]
volts. Voltages approximately ±10% beyond that
range may be converted to usable levels, depending
on the requirements of the equipment. See graphs
on the back page.
The AR-1215 has eight [AR-2306 has ten IEC-320]
