How to enter the test mode • Reset the unit while holding the "FM" key and preset "6" key. • All indication segments go ON at the beginning of the test mode. 2. How to release the test mode • Simply reset the unit. • (NOTE) The test mode should not released in conditions of ACC OFF, power OFF, momentary power down or the panel off. 3. Test mode • Blanking Skip (B.S) OFF. • Eject a tape by pressing "ATT" key. 4. Audio adjustment • Enter the audio mode by pressing the "AUD" key or "OPEN/CLOSE" key on the remote controller. • Set the volume level to be -10dB. In that case, "30" should be shown on the display. • Loudness OFF. • The BASS/MIDDLE/TREBLE and BALANCE/FADER can be adjusted to the full-boost/full-cut and full-front/ full-rear each by pressing the "UP" and "DOWN" keys. 5. Menu mode • Enter the menu mode by pressing "CLK" key or "DNPP" key on the remote controller. • Only on models with RDS function, Local Seeking should be first menu.
