Before Using the DTR-10.5
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 DTR-10.5’s
remote control sensor, as shown below. The DTR-10.5’s
[Standby] indicator flashes while a signal is being
received from the remote controller.
Notes:
• The remote controller may not work reliably if the
DTR-10.5 is subjected to bright light, such as direct
sunlight or inverter-type fluorescent lights. Keep this
in mind when installing the DTR-10.5.
• If another remote controller of the same type is used
in the same room, or the DTR-10.5 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
DTR-10.5 is installed in a rack behind colored glass
doors. Keep this in mind when installing the
DTR-10.5.
• The remote controller will not work if there’s an
obstacle between it and the DTR-10.5’s remote
control sensor.
• 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 DTR-10.5 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.
