Frequently Asked Questions - CTZ109 AIWA

How to set the clock on the Aiwa CTZ109 car stereo?

To set the clock, turn on the device with PWR, then press and hold DISP for more than 2 seconds until the hour flashes. Use TUNE ▼ for hours and TUNE ▲ for minutes. Press DISP to start the clock at 0 seconds.

How to manually preset a radio station?

After selecting the band (FM1, FM2, FM3 or AM) with BAND, tune the desired station with TUNE ▼ or TUNE ▲. Then, press and hold one of the preset buttons (1-6) for about 2 seconds until the number appears next to the frequency.

How to use the MY INFO function (radio timer)?

With the device off, press and hold MY INFO for 2 seconds. 'PO' flashes. Press SEL, then set the on time with TUNE ▼/▲. Press SEL again to set the station, then a third time to set the off time. Confirm by pressing and holding MY INFO for 2 seconds. To activate, briefly press MY INFO in radio mode.

How to connect a portable CD player to the car stereo?

First remove any inserted cassette. Connect the portable CD/MD player to the CD/MD IN jack (3.5 mm) on the front panel. Turn on the device with PWR, then press CD/MD IN to switch to CD mode. 'Cd' appears on the display.

What to do if the cassette does not play properly?

First check that the tape is tightly wound (use a pencil to take up slack). Avoid 90-minute or longer cassettes as they are too thin. If the problem persists, clean the playback head with a cleaning cassette. Also make sure to remove the protective tab (press EJECT).

How to adjust bass and treble?

Press SEL repeatedly until the BASS (bass) or TRE (treble) indicator flashes. Then use the + or - buttons to increase or decrease the level. The H-BASS function provides additional bass boost.

What is the H-BASS function?

The H-BASS (High Bass) function enhances bass for a more powerful sound. Press the H-BASS button to activate: the 'BASS' indicator lights up. Press again to deactivate.

How to switch from local mode to DX mode in radio?

In radio mode, press the LO button to activate local mode (LO), which only searches for strong stations. Press again to switch to DX (distance) mode to receive weaker signals. The 'LO' indicator lights up in local mode.

How to clean the playback head?

Use a special cleaning cassette about once a month. Insert it into the compartment and let it play for a few seconds. Regular cleaning prevents loss of treble and maintains sound quality.

The car stereo does not turn on, what to check?

First check the fuse: it must be the same amperage as the original (indicated on the device). Make sure the car has a negative ground and that the battery is properly connected. If the problem persists, consult a professional.
