• Recharging already charged or half-charged batteries will shorten their lifetime. We therefore recommend that you let the rechargeable ECO-PLUS NiMH battery run till it is completely empty before you recharge it.
•To avoid a short circuit, do not let the battery touch any metal object.
• If the battery becomes empty soon after recharging, then either its contacts are dirty or it has reached the end of its lifetime.
Mains adapter (supplied or optionally available)
Use only the AY 3170 adapter (4.5 V / 300 mA direct current, positive pole to the center pin). Any other product may damage the player.
1 Make sure the local voltage corresponds to the power
adapter’s voltage.
2 Connect the power adapter to the 4.5V DC socket of
the player and to the wall socket.
Note: Always disconnect the adapter when you are not using it.
Environmental information

The indication NO dISC is displayed
•Check that the CD is clean and correctly inserted (label-side upward).
•If your lens has steamed up, wait a few minutes for this to clear.
The indication NF dISC is displayed
•CD-RW (CD-R) was not recorded properly. Use FINALIZE on your CD-recorder.
The indication
•If HOLD is activated, then deactivate it.
• Electrostatic discharge. Disconnect power or remove batteries for a few seconds.
The CD skips tracks
• The CD is damaged or dirty. Replace or clean the CD.
• resume, shuffle or program is active. Switch off whichever is on.
HOLD is on and/or there is no reaction to controls
Troubleshooting
No sound or bad sound quality.
•PAUSE might be active. Press 2;.
•Loose, wrong or dirty connections. Check and clean connections.
•Volume might not be appropriately adjusted. Adjust the volume.
•Strong magnetic fields. Check player’s position and connections. Also keep away from active mobile phones.
For in-car use, check that the cassette adapter is inserted correctly, that the car cassette player’s playback direction is correct (press autoreverse to change), and that the cigarette lighter jack is clean. Allow time for temperature change.
CAUTION Use of controls or adjustments or performance of procedures other than herein may result in hazardous radiation exposure or other unsafe operation.

SAFETY & WARNINGS

© WARNING
All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD). Careless handling during repair can reduce life drastically. When repairing, make sure that you are connected with the same potential as the mass of the set via a wristband with resistance. Keep components and tools at this potential.
f ATTENTION
Tous les IC et beaucoup d´autres semi-conducteurs sont sensibles aux décharges statiques (ESD). Leur longévite pourrait être considérablement écourtée par le fait qu´aucune précaution nést prise à leur manipulation. Lors de réparations, s´assurer de bien être relié au même potentiel que la masse de l´appareil et enfileer le bracelet serti d´une résistance de sécurité. Veiller à ce que les composants ainsi que les outils que l´on utilise soient également à ce potentiel.

d WARNUNG
Alle ICs und viele andere Halbleiter sind empfindlich gegenüber elektrostatischen Entladungen (ESD). Unsorgfältige Behandlung im Reparaturfall kann die Lebensdauer drastisch reduzieren. Sorgen Sie dafür, daß Sie im Reparaturfall über ein Puls­armband mit Widerstand mit dem Massepotential des Gerätes verbunden sind. Halten Sie Bauteile und Hilfsmittel ebenfalls auf diesem Potential.
ESD
ñ WAARSCHUWING
Alle IC´s en vele andere halfgeleiders zijn gevoelig voor electrostatische ontladingen (ESD). Onzorgvuldig behandelen tijdens reparatie kan de levensduur drastisch doen vermindern. Zorg ervoor dat u tijdens reparatie via een polsband met weerstand verbonden bent met hetzelfde potentiaal als de massa van het apparaat. Houd componenten en hulpmiddelen ook op ditzelfde potentiaal.
i AVVERTIMENTO
Tutti IC e parecchi semi-conduttori sono sensibili alle scariche statiche (ESD). La loro longevità potrebbe essere fortemente ridatta in caso di non osservazione della più grande cauzione alla loro manipolazione. Durante le riparationi occorre quindi essere collegato allo stesso potenziale che quello della massa delápparecchio tramite un braccialetto a resistenza. Assicurarsi che i componenti e anche gli utensili con quali si lavora siano anche a questo potenziale.
