IR PROGRAMMING

Ideal Programming Conditions

In order to minimize interference and maximize the reliability of source control, follow these guidelines

during programming:

1. Eliminate direct or bright indirect sunlight near the PX-600 Programmer.

2. Turn off any halogen, fluorescent and neon lights in the area.

3. Position Programmer so that no lights, even incandescent lights, shine directly into the IR input

window.

4. Hold the transmitter for the source equipment you are programming 2” to 6” from the PX-600

Programmer. Hold it level and squarely aligned with the red IR input window.

Except as directed elsewhere in these Tech Notes, when you enter a command into the PX-600

Programmer, press and hold the button on the IR remote until you see the words: “Storage

Successful” on the LCD screen.

CD - Multiple Skip Track

You may encounter some CD players that skip more than one track when you issue the SKIP TRACK by

pressing the CD button the second and subsequent times. These players probably utilize 32 bit IR codes.

When learning these 32 bit codes, the PX-600 will take 2-3 seconds before indicating “Storage Successful”,

whereas 16 bit codes are stored almost immediately. When 32-bit codes are learned and played back, often

the player sees two separate commands and thus skips more than one track.

To compensate for this and skip only one track, get into programming and proceed to the spot where you

are to enter the SKIP TRACK command. Briefly tap SKIP TRACK on the CD’s remote and immediately

press and hold another button on the remote until the PX-600 indicates “Storage Successful” on the display.

The PLAY button works well for this unless the player has a combination PLAY/PAUSE button. If this is

the case, or if the player is affected in some other way when you press PLAY while it is already in PLAY,

use a command from a remote that has nothing to do with the audio system to complete the storage of that

IR address. The point is to fill the space allotted for the command without duplicating the SKIP TRACK

command.
