What If None of the Codes Work?

If none of the codes listed for your brand of device operate the device correctly, you can search through the code library for a valid code.

Improving Your Reaction Time

When you search the code library, you need to be ready to press SELECT as soon as the remote turns off your device. Therefore, make sure you are familiar with the location of the SELECT key before you begin this procedure.

Sizing Up the Libraries

The mode keys blink twice when the remote reaches the last code in a library. You do not need to count codes. However, knowing the size of each library will help you determine how long it will take to cycle through all of the codes in the library. Each library contains the following number of codes:

•	CBL mode: 23	•	TV mode: 225	• DVD mode: 206
•	VCR mode: 210	•	AUX mode: 38

Searching the Code Library

(Program Code 9 9 1)

1.Turn on the device.

2.Press and hold SELECT and the appropriate mode key (CBL, TV, VCR, DVD, or AUX) until the mode keys blink twice. For example, to search for a TV code, press and hold SELECT and TV at the same time.

Note: If you reassigned mode keys, you may, for example, press SELECT and VCR to search for a TV code to assign to the VCR mode key.

3.Press 9 9 1. The mode key you selected in step 2 blinks twice.

4.Point the remote toward the device, and press PLAY . The remote automati- cally tests each code in its library, beginning with the most common codes. The mode key blinks once each time the remote transmits a new code. The mode key blinks twice when it reaches the last code.

5.As soon as the device powers off, press SELECT.

6.Verify the new code is correct by pressing POWER.

7.Did the device power on again?

•If yes, press SELECT to assign the code.

•If no, complete the following steps:

a)Turn the device on.

b)Press or to step forward or back to the correct code.

c)When the device turns off, press SELECT to assign the code.

8.Go to Which Code Worked to identify the code that controls your device. After you identify the code, record the code in the space provided on the cover of this guide.

Change Channel Control

Your remote is originally programmed in one of the following ways:

•The remote controls channels for a single device, such as the cable box, whether the remote is in CBL, VCR, DVD, or TV mode. The AUX mode always retains separate channel control.

•The remote controls channels for different devices, depending on the mode key you press.

Try your remote to see how the channel control currently works. The channel keys include , , Digits 0-9, LAST, and FAV. If you want to change the channel control, complete the procedure that fits your needs.

Tip: Consider programming the remote to control channels for just the cable box to ensure you do not accidentally tune off the proper channel for the TV (usually channel 3 or 4).

Controlling Channels For One Device

(Program Code 9 9 7)

1.Press and hold SELECT and CBL until all mode keys blink twice.

2.Press 9 9 7. The CBL key blinks twice.

3.Press the mode key associated with the device you want the channel keys to control. For example, if you want to assign channel control to your TV only, press TV. All mode keys blink three times.

Notes:

•The channel keys now always control the device associated with the mode you selected in this step, whether in TV, CBL, DVD, or VCR mode.

•In AUX mode, the remote always controls channels for the device assigned to the AUX key.

Controlling Channels For Different Devices

(Program Code 9 9 7)

1.Press and hold SELECT and CBL until all mode keys blink twice.

2.Press 9 9 7. The CBL key blinks twice.

3.Press SELECT. All mode keys blink three times.

Result: After you press SELECT, the channel keys now control the device associated with the mode key you select. For example, in TV mode, the channel keys control the TV, but in CBL mode, the channel keys control the cable box.
