This device is not adjusted but reception can be checked with the temporary Preset values.

1. Turn OFF the power.
2. While pressing [DISPLAY] button and [MEMORY] button together, turn ON [POWER] button.
3. When you enter temporary PRESET setting mode, the “MEMORY” display flashes.  The only difference in this mode is the use of the

temporary Preset values.  Otherwise, operation is normal.

4. For the FM and AM band, the PRESET values are as follows.

5. For the DAB band, there are no temporary Preset values.

Instead, the CH labels handle this with “MENU” - “DAB TUNE AID” as follows.

6. End temporary PRESET mode with a Power OFF.
