Resetting the stations on a DPR39 - The Audio Players & Recorders

This says it is easy to set up, but there is a Fixya post that says there are a reset button in both units. In mine, I have to put a new battery in the main unit and then remove and replace the button in the remote unit.

“when up & down scan buttons pressed, just keeps scanning w/out finding station. it does lock into a station when manually scanned. need reset & if so, how?” Don't worry. Your amp is normal. Your situation happens to any denon, onkyo and yamaha av-amp always due to extremely sensitive tunning unit. No need to reset. Tune any wanted station by another radio and jot freq. down. Enter desired freq. into the av-amp and store it.

Hi Richard do not own one of these stations but normally you can obtain instructions on line or try to contact the manufactuer

first you must make sure the station inside and the station outside are on the same Channel. then look for the reset button on both the one outside is probably in the battery house as well as the station selector switch. after resetting both they should be able to talk to each other again.

Restore Factory Default Settings When you restore factory default settings to the base station, you clear your Internet connection settings and any special base station configurations that you have established. After the restore is complete, you will need to reconfigure your base station settings or restore these settings from a backup file. You should restore the original factory default settings only under the following circumstances: O You are experiencing serious problems with your base station, and resetting the base station does not fix the problem. O You cannot remember your base station password. In this situation, you must restore the factory default settings by using the Restore button on the base station, and then use the default password admin to log on to the Base Station Management Tool. To restore factory default settings 1. Open the Base Station Management Tool, and then click Management. 2. On the Management menu, click Back Up and Restore Settings. 3. Under Restore factory default settings, click Restore Factory Default Settings. While the original factory default settings are being restored to the base station, the Power light on the base station turns orange. When the light is solid green, the settings have been restored. If you want to open the Base Station Management Tool after the settings have been restored, type admin as the password on the Logon page. Do not attempt to log on to the base station until the settings are restored and the Power light on the base station is solid green. After you restore the factory default settings to the base station, you should navigate to each page of the Base Station Management Tool and reestablish the network settings you want, or restore the base station settings by using a backup file. For information about creating a backup file of your settings, see the following section. Be sure to establish your unique base station password as soon as possible after restoring the factory default settings to prevent unauthorized users from logging on. For more information, see “Change the Base Station Password.” please rate this answer, thanks

Reset method is power + volume + at the same time

Probably, however, you just need to go to the new station and press the play button to confirm the radio station change - then it will play the correct station
