Before Using the RDC-7.1
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 the 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.
• Expired batteries should be removed as soon as
possible to prevent damage from leakage or
corrosion.
To use the remote controller, point it at the RDC-7.1’s
remote control sensor, as shown below. The RDC-7.1’s
[Standby] indicator flashes while a signal is being
received from the remote controller.
Notes:
• The remote controller may not work reliably if the
RDC-7.1 is subjected to bright light, such as direct
sunlight or inverter-type fluorescent lights. Keep this
in mind when installing the RDC-7.1.
• If another remote controller of the same type is used
in the same room, or the RDC-7.1 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
RDC-7.1 is installed in a rack behind colored glass
doors. Keep this in mind when installing the
RDC-7.1.
• The remote controller will not work if there’s an
obstacle between it and the RDC-7.1’s remote control
sensor.
• (RC-555M only) You can set the transmission signal
format to infrared (IR), or radio frequency (RF) for
use with the optional RF Receiver. This is useful
when, for example, the RDC-7.1 is installed in a rack
or is not in line of sight of the remote controller.
• To select AMP mode, press the scroll wheel. “AMP”
appears on the display.
