Integra DTR-7.4 ユーザーズマニュアル

• 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.

• Dead batteries should be removed as soon as possible 

to prevent possible leakage and corrosion.

To use the remote controller, point it at the DTR-7.4’s 
remote control sensor, as shown below. The DTR-7.4’s 
Standby indicator flashes while a signal is being 
received from the remote controller.

 

• The remote controller may not work reliably if the 

DTR-7.4 is subjected to bright light, such as direct 
sunlight or inverter-type fluorescent lights. Keep this 
in mind when installing the DTR-7.4.

• If another remote controller of the same type is used 

in the same room, or the DTR-7.4 is installed close to 
equipment that uses infrared rays, the remote control-
ler may not work reliably.

• Don’t put anything, such as a book, on the remote 

controller, because the buttons may be pressed inad-
vertently, thereby draining the batteries.

• The remote controller may not work reliably if the 

DTR-7.4 is installed in a rack behind colored glass 
doors. Keep this in mind when installing the 
DTR-7.4.

• The remote controller will not work if there’s an 

obstacle between it and the DTR-7.4’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 exam-
ple, the DTR-7.4 is installed in a rack or is not in line 
of sight of the remote controller.
