You may preset six AM station frequencies on the AM band. This display will show your band selection, along with the station frequency, for ten seconds before returning to display the time of day. If you press the AM/FM button while the radio is off or while the CD is playing, the radio will switch back to the last played AM or FM station without ejecting the CD.

After you release the rocker button, the display shows the station frequency and band for ten seconds, then returns to display the time of day.

SEEK : Use the seek function to automatically proceed to the next available frequency that can be received with good sound quality. Press and hold one side of the TUNE/SEEK rocker button until a tone sounds, indicating that the seek function has been activated. The radio will begin to change station frequencies until you release the rocker button, then will stop at the next receivable station frequency. Hold the top side of the rocker button to increase the station frequency or the bottom side to decrease the station frequency. If you would like to cancel the seek function before it reaches the next receivable station, press the TUNE/SEEK rocker button in the opposite direction that it is currently seeking.

SCN (Scan): When you press the SCN button, the radio will sequentially sample all of the receivable AM or FM station frequencies with good sound quality and will pause for 5 seconds at each. To cancel the scan function, press the SCN button a second time. If a station frequency is currently being played when the scan function is cancelled, that station will continue to play. If the radio is between station frequencies when you cancel the scan function, the radio will return to the last station frequency played.

The six pushbuttons let you choose and set your favorite stations. You can set up to six AM stations and 12 FM stations (six FM1 and six FM2).

Error Messages, Probable Causes, and Solutions

Several conditions will cause errors preventing proper CD operation. These include loading a CD upside down, moisture on the CD, and a dirty damaged CD. Moisture on the focusing mechanism internal to the CD player CD player may also cause an error. While using your CD player, if the radio detects an error, it will let you know by either ejecting the CD or by temporarily displaying "ERR". If an error message appears on your display, please check the probable causes of the error to correct the problem. Following is a list of possible problems, along with the probable causes and solutions.

If the following solutions do not correct the problem, you may have a CD player failure. See your Retailer or authorized service provider for service.

If the CD ejects upon insertion (right after loading):

First check to see if you are inserting the CD upside down. It should be inserted with the label facing upwards. Reinstall the CD label side up. If the CD still ejects when it is install label side up, you could have a warped or cracked CD. Check the CD for problems. Avoid using any cracked or deformed CDs.
