This unit is not disconnected from the AC power source as
long as it is connected to the wall outlet, even if this unit
itself is turned off. This state is called the standby mode.
In this state, this unit is designed to consume a very small
quantity of power.
Voltage Selector (China and General Models only)
The voltage selector on the rear panel of this unit must
be set for your local main voltage BEFORE plugging into
the AC main supply.
Voltages are 110/120/220/240 V AC, 50/60 Hz.
FREQUENCY STEP switch (China and General Models
only)
Because the interstation frequency spacing differs in
different areas, set the FREQUENCY STEP switch (located
at the rear) according to the frequency spacing in your area.
Before setting this switch, disconnect the AC power plug of
this unit from the AC outlet.
FOR CANADIAN CUSTOMERS
TO PREVENT ELECTRIC SHOCK, MATCH WIDE BLADE
OF PLUG TO WIDE SLOT AND FULLY INSERT.
THIS CLASS B DIGITAL APPARATUS MEETS ALL
REQUIREMENTS OF THE CANADIAN INTERFERENCE-
CAUSING EQUIPMENT REGULATIONS.
NOTES ABOUT THE REMOTE CONTROL TRANSMITTER
Battery installation
1
Battery replacement
If you find that the remote control transmitter must be used
closer to the main unit, the batteries are weak. Replace both
batteries with new ones.
Notes
Use only AA, R6, UM-3 batteries for replacement.
Be sure the polarities are correct. (See the illustration inside
the battery compartment.)
Remove the batteries if the remote control transmitter will
not be used for an extended period of time.
If batteries leak, dispose of them immediately. Avoid
touching the leaked material or letting it come in contact with
clothing, etc. Clean the battery compartment thoroughly
before installing new batteries.
After you change batteries, make sure to press the RESET
button inside the battery compartment.

Notes
There should be no large obstacles between the remote
control transmitter and the main unit.
If the remote control sensor is directly illuminated by strong
lighting (especially an inverter type of fluorescent lamp etc.),
it might cause the remote control transmitter not to work
correctly. In this case, reposition the main unit to avoid direct
lighting.
