Setting the Voltage Selector
(Worldwide model only)
The Worldwide model has a voltage selector for compatibility with
power systems around the world. Before you plug in this model,
make sure that the voltage selector is set to the correct voltage for
your area. If it isn't, use a small screwdriver to set it as appropriate.
For example, if the voltage in your area is 120 volts (V), set the
selector to “120V.” And if it’s between 220 and 230 volts (V), set it
to “220-230V.”
2 Insert the two supplied batteries (AA/R6) in
accordance with the polarity diagram inside the
battery compartment.
3 Close the battery compartment.
Notes
• The supplied batteries should last for about six months,
although this will vary with usage.
• If the remote controller doesn’t work reliably, try replacing
both batteries.
• Don’t mix new and old batteries, or different types of batteries.
• If you intend not to use the remote controller for a long time,
remove the batteries to prevent possible leakage and corrosion.
• Flat batteries should be removed as soon as possible to prevent
possible leakage and corrosion.
Using the Remote Controller
To use the remote controller, point it at the HT-R420’s remote
control sensor, as shown below. The HT-R420’s STANDBY
indicator flashes while a signal is being received from the remote
controller.
Notes
• The remote controller may not work reliably if the HT-R420 is
subjected to bright light, such as direct sunlight or inverter-type
fluorescent lights. Keep this in mind when installing the HT-
R420.
• If another remote controller of the same type is used in the same
room, or the HT-R420 is installed close to equipment that uses
infrared rays, the remote controller may not work reliably.
• Don’t put anything, such as a book, on the remote controller,
because the buttons may be pressed inadvertently, thereby
draining the batteries.
• The remote controller may not work reliably if the HT-R420 is
installed in a rack behind colored glass doors. Keep this in mind
when installing the HT-R420.
• The remote controller will not work if there’s an obstacle
between it and the HT-R420’s remote control sensor.
