FOIRE AUX QUESTIONS - Walkman WM-DD9 SONY

Comment insérer la cassette dans le Walkman WM-DD9 ?

Ouvrez le couvercle situé sur le dessus de l'appareil. Insérez la cassette avec la face souhaitée visible (la fenêtre de la cassette vers le haut). Refermez le couvercle jusqu'au déclic.

Que faire si la cassette ne tourne pas ou si le son est ralenti ?

Cela indique souvent que la courroie d'entraînement est détendue ou cassée. Remplacez la courroie par une neuve. Vérifiez également que les piles sont suffisamment chargées.

Comment utiliser la fonction Dolby B NR ?

Appuyez sur le bouton marqué 'Dolby B NR' pour activer la réduction de bruit. Utilisez cette fonction lors de la lecture de cassettes enregistrées avec Dolby B pour réduire le souffle.

Puis-je utiliser des piles rechargeables ?

Oui, vous pouvez utiliser des piles rechargeables NiMH de type AA. Assurez-vous qu'elles fournissent une tension de 1,2 V chacune (soit 2,4 V au total). L'autonomie peut être légèrement inférieure à celle des piles alcalines.

Comment nettoyer les têtes de lecture ?

Utilisez un coton-tige imbibé d'alcool isopropylique à 90%. Frottez délicatement les têtes (les petits blocs métalliques) et le cabestan (l'axe métallique). Laissez sécher quelques minutes avant d'utiliser l'appareil.

Le son est déformé ou faible sur un seul canal, que faire ?

Vérifiez d'abord le casque sur un autre appareil. Si le problème persiste, nettoyez les têtes et le commutateur auto reverse. Un mauvais contact des têtes peut aussi en être la cause. Si le problème subsiste, faites vérifier l'appareil par un technicien.

Quelle est la durée de vie des courroies ?

Les courroies en caoutchouc durent généralement 10 à 20 ans selon les conditions d'utilisation. Si elles deviennent collantes ou cassantes, remplacez-les immédiatement pour éviter d'endommager le mécanisme.

Comment régler le volume ?

Utilisez la molette de volume située sur le côté de l'appareil. Tournez-la dans le sens horaire pour augmenter le volume, antihoraire pour diminuer. Commencez toujours à volume faible pour protéger votre ouïe.

Puis-je enregistrer avec le Walkman WM-DD9 ?

Non, le WM-DD9 est un lecteur uniquement. Si vous souhaitez enregistrer, utilisez un enregistreur dédié ou un autre modèle Sony avec fonction d'enregistrement.

Que faire si l'auto reverse ne fonctionne pas ?

L'auto reverse utilise des têtes pivotantes ou un capteur de fin de bande. Si le mécanisme ne s'active pas, nettoyez les contacts et lubrifiez légèrement les engrenages avec une goutte d'huile silicone. Si le problème persiste, le système peut être déréglé et nécessiter une réparation.

Features

- Two-motor Disc Drive mechanism and Quartz lock capstan servo assure accurate and stable tape transport, greatly reducing wow and flutter. One motor is provided for the forward direction and another for the reverse direction. Since the rotation of motors is controlled by the accurate frequency of the quartz servo, distortion of the sound caused by the unit being moved is slight.

Capstan for the forward direction

• Advanced EX amorphous head

Double gutters and fine gap produce clearer sound in the lower and upper reister respectively.

Single crystalline material employed for the wiring of the head transmits the signal accurately.

• Twin turbo earphones with larger sub turbo-duct allow a wider dynamic range, and its shape provides a comfortable fitting.
• The sturdy 2 mm-thick (maximum) casing assures the durability of the unit.
  • Dolby NR* system (B and C types) reduces tape hiss noise.
• MEGA BASS selector for heavy and powerful mega bass sound.
• A Size AA (R6) battery or rechargeable battery can be inserted without attaching a case to the unit.

Using with a Rechargeable Battery

Before using the unit, charge the rechargeable battery with the supplied battery charger.

How to charge

1 Plug in the battery charger after inserting the rechargeable battery.
2 The charge indicator blinks and then comes on. Unplug the battery charger when the indicator goes off.

High speed charging (50% charge in 10 minutes)	After the charge indicator flashes for a few (approx. 10) seconds (checking the remaining amount of power), it charges to blinking and high speed charging starts.*When the indicator lights steadily (10 minutes later), the rechargeable battery is 50% charged.
Full charge	Leave the charger for approx. 20 more minutes until the indicator goes off. (Total charging time: approx. 30 minutes)

- If the indicator lights steadily instead of blinking after a few (approx. 10) seconds of flashing

This shows that the power in the rechargeable battery still has power. If this happens, charging is in the normal speed mode instead of the high speed mode. Leave the charger and the battery will be charged when the indicator goes off.

Charging time varies according to the remaining amount of power. (approx. 40 min.)

Note If an exhausted or inferior rechargeable battery is inserted, blinking of the indicator may not change to steady lighting at either position of the selector.

In this case, replace the rechargeable battery with a new one.

You cannot charge the battery at a high speed. The indicator lights up and the battery will be charged in approx. 40 minutes. (The indicator will go off.)

Notes

• Be sure to plug in the battery charger after inserting the rechargeable battery, otherwise the battery will not be charged porperly.
  • The battery may become warm up during charging, but this is not a problem.
• Use the supplied battery charger only for the NC-5WM and NC-6WM.
• Do not use the battery charger near a receiver. If you do, it may interfere with the receiver.
• Unplug the battery charger from the wall outlet when the indicator goes off.
• If the rechargeable battery is new or after a long storage, it may not charge completely. (The operating time is shorter.) This is not a problem and the battery will be charged completely after it has been used several times.
