Sony MDR-ZX780DC Headphones

If the headset is not used for a long time, it may take longer to charge the battery.

If the life of the built-in rechargeable battery drops significantly, the battery should be replaced. Consult your nearest Sony dealer for replacement

of the rechargeable battery.

Avoid exposure to temperature extremes, direct sunlight, moisture, sand, dust or mechanical shock. Never leave the headset in a car parked in the

sun.

If the computer enters into hibernation mode while connected to the headset, charging will not be completed properly. Check the setting of the

computer before charging. The indicator (red) will go off automatically if the computer enters into hibernation mode. Charge the headset again in

this case.
