Charging The Batteries; Notes On Battery Charging - Pioneer SE-MJ771BT Bedienungsanleitung

3. Charging the batteries

The unit's battery must be recharged before use.
The accessory micro-USB cable must be used for recharging the unit's battery.
Connect the appropriate connector on the accessory micro-USB cable to the micro-
USB port on the headphones, and the USB plug on the other end to a USB port on
a computer. (see Fig. 3).
• When recharging begins, the LED indicator on the headphones will light red.
• If recharging is performed with the unit's power turned ON, the power will automati-
cally turn OFF. The unit cannot be used during recharging.
• Full recharging requires about 5 hours; when recharging is completed, the LED
indicator will turn off.
• With a full battery charge, the maximum continuous usable time is about 32 hours;
the maximum continuous time the headphones can be left in standby mode is about
800 hours.
• When the rechargeable battery's power become low, a beeping sound can be heard
from the unit once every 3 minutes, and the LED indicator flashes red. In this case,
recharge the battery before using the unit.
Note
• Battery recharging time and usable battery time may vary depending on ambient
temperature and frequency of use.
• Do not place metal objects near the headphones' charging contacts, since danger-
ous electrical shorts or abnormal heating may result.

Notes on battery charging

• Battery performance is influenced by the surrounding temperature. Charge the sup-
plied rechargeable batteries within a temperature range of 10 to 35 degrees celcius.
• Do not overcharge batteries. In order to protect batteries, do not repeatedly charge
the batteries that are already fully charged.
• Batteries become slightly warm when charging. This is not a malfunction.
• Please use the accessory micro-USB cable for recharging; using other cables may
result in malfunction.
• Recharging may not be possible if computer is in power-saving mode.
• Always confirm the proper shape and orientation of the micro-USB cable plugs
before attempting to connect to the headphones and computer.
• Do not use micro-USB cables when tightly twisted or bundled, since fire or electric
shock might result.
• Bluetooth function cannot be used during recharging.
To listen to playback while recharging, see page 12, "Using the Headphone cord."
