Frequently Asked Questions - KH 23 EBENCH

How to turn on the radio and select a station?

Set the function switch (1) to 'Radio', then choose the waveband with the wave selector (2) (FM or MW). Turn the tuning control (29) to find the desired station and adjust the volume with the volume control (5). To turn off, set the function switch to 'Cassette'.

How to record a radio program on cassette?

First select the radio station as described above. Insert a blank cassette into the cassette compartment (19). Press pause (25), then simultaneously press record (20) and play (21). Release pause to start recording. The automatic level control (ALC) adjusts the level. To stop, press stop/eject (24).

How to program track playback on a CD?

In CD stop mode, press program (9) once: the program indicator (16) lights up. Use the skip forward (7) or skip back (8) keys to select a track, then press program again to memorize it. Repeat up to 20 tracks. To play the program, press play/pause (12). Open the CD lid to clear the program.

What to do if FM reception is poor or noisy?

Fully extend the FM antenna (3) and orient it to improve reception. You can also set the tuning control (29) to mono position (if available) to reduce noise. In weak signal areas, use 'MONO' position for clearer listening.

Can I use rechargeable batteries?

The manual specifies 8 UM-2 (size C) batteries. Rechargeable batteries of the same size can be used, but their nominal voltage (1.2 V instead of 1.5 V) may reduce performance. Ensure correct polarity.

How to clean the tape player heads?

Regularly clean the playback and recording heads with a cotton swab dipped in isopropyl alcohol or use a special cleaning cassette. This prevents loss of sound quality due to dust deposits.

What does the FM stereo indicator correspond to?

The FM stereo LED indicator (18) lights up when receiving a stereo broadcast on the FM band. It flickers or goes out if reception is too weak; switch to mono mode.

How to repeat a track or the whole CD?

During playback, press repeat (10) once to repeat the current track (the repeat indicator (15) flashes). Press twice to repeat the entire CD (steady indicator). Press until the indicator goes out to cancel.

The cassette deck stops by itself, is this normal?

Yes, it is normal: the auto stop activates when the tape reaches the end during playback or recording. Press stop/eject (24) to rewind or change the cassette.
