Integra Comprehensive Guide to Using Your DTR 7.4 Stereo Receiver

Before Using the DTR-7.4

Installing the Batteries

1 To open the battery compartment, press the small hollow and slide off the cover.

2 Insert the two supplied batteries (AA/R6) in accordance with the polarity diagram inside the battery compartment.

3 Put the cover onto the remote controller and slide it shut.

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.

•Dead 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 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.

Notes:

•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.
