BLUETOOTH wireless technology operates within a range of about 10 m (30 feet). The maximum communication range may vary depending on obstacles (human body, metal, wall, etc.) or electromagnetic environment.

The antenna of the SONY MDR-1ABT is built into the part illustrated by the dotted line. The sensitivity of the BLUETOOTH communications will improve by turning the antenna of the connected BLUETOOTH device to face the antenna of this unit.

BLUETOOTH communications may be disabled, or noise or audio dropout may occur under the following conditions:

– There is a human body between the unit and the BLUETOOTH device.

– There is an obstacle, such as a metal or a wall, between the unit and the BLUETOOTH device.

– A device using a 2.4 GHz frequency, such as a Wi-Fi device, cordless telephone, or microwave oven, is in use near this unit.

Because BLUETOOTH devices and Wi-Fi (IEEE802.11b/g/n) use the same frequency (2.4 GHz), microwave interference may occur resulting in noise or audio dropout or communications being disabled if this unit is used near a Wi-Fi device. In such a case, perform the following:

– Use this unit at least 10 m (30 feet) away from the Wi-Fi device.

– If this unit is used within 10 m (30 feet) of a Wi-Fi device, turn off the Wi-Fi device.

– Install this unit and the BLUETOOTH device as near to each other as possible.

Microwaves emitting from a BLUETOOTH device may affect the operation of electronic medical devices. Turn off this unit and other BLUETOOTH devices in the following locations, as it may cause an accident:

– in hospitals, near priority seating in trains, locations where inflammable gas is present, near automatic doors, or near fire alarms.

This unit supports security capabilities that comply with the BLUETOOTH standard to provide a secure connection when the BLUETOOTH wireless technology is used, but security may not be enough depending on the setting. Be careful when communicating using BLUETOOTH wireless technology.

We do not take any responsibility for the leakage of information during BLUETOOTH communications.

Connection with all BLUETOOTH devices cannot be guaranteed.

This unit can be charged using USB only. Personal computer with a USB port is required for charging.

This unit cannot be turned on, nor can the BLUETOOTH function be used, during charging.

If you do not use the unit for a long time, the rechargeable battery may be depleted quickly. The rechargeable battery will be able to hold a charge after it is discharged and recharged several times. When storing the unit for a long time, charge the battery once every half year to prevent over-discharge.

If the length of time you can use the unit becomes extremely short, the rechargeable battery should be replaced with a new one. Please contact your nearest Sony dealer for a battery replacement.

When charging, the headset cannot be used. Be sure to turn off the power of the headset.

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 even if charging is not complete if the computer enters hibernation mode. Charge the headset again in this case.

Because the headset is of a high-density enclosure design, forcing it against your ears may result in eardrum damage. Pressing the headset against your ears may produce a diaphragm click sound. This is not a malfunction.
