OPERATION

Controls system. Controls sound volume. Selects each source. Controls each mute output. Amplifies power so that the speaker can drive audio signal. Equalizer amplifier for cassette tape sound. Resets power supply. Decodes RDS signal. Works when ACC operation stops. Works when the back-up voltage comes less than 9.2V. Works when the back-up works. Works when the power comes. Works when the power comes. Works when the power comes. Works when the power comes. Works when the power comes. Works when the back-up voltage detection or the changer mute or -com mute works. Works when the amplifier mute works. Works when the back-up voltage detection or the changer mute or -com mute works. Works when FM mode is being selected. Works when AM mode is being selected. Works when TAPE mode is being selected. Works when Q260 works. Works when power supply is being reset and IC6 works. Works when the back-up works and panel is on the unit. Stops during POWER OFF and ALL OFF modes. Works when P-CON is being short-circuited on GND. Inhibits protection SW function when P-CON works momentary. Stops during POWER OFF and ALL OFF modes. Works when the back-up voltage detection or the changer mute or -com mute works. For RDS decorder (IC7). Works when receiving FM signal. Stops when seeking FM signal. For noise level detection.

TEST MODE

1. 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 is not canceled by ACC OFF, power OFF, momentary power down or the panel off. 3. Audio adjustment Set the volume level to -10dB (which is shown as "30" on the display). Loudness OFF. The BASS/TREBLE and BALANCE/FADER can be set to the full-boost/full-cut and fullfront/full-rear each by pressing the "Track UP" / "Track DOWN" keys. Sound coordination doesn't appear for the feed.
