Putting the RS 165 into operation Charging the rechargeable batteries CAUTION Danger of damage to the headphones! If you insert non-rechargeable batteries into the battery compartments, the batteries may leak during charging and can damage your headphones. ̈ Do not place the headphones on the headphones holder if you are using non-rechargeable batteries. In general, a complete charging cycle takes about 8.5 hours. However, 8.5h before using the headphones for the first time, charge the rechargeable batteries for at least 16 hours without interruption to optimize the perfor- mance of the batteries. When the rechargeable batteries are almost empty, the HDR status LED turns red and you hear beeps in the headphones. The headphones switch off after few minutes. ̈ Place the headphones on the headphones holder of the transmitter. You may place the headphones on either side provided that the charging contacts of the headphones and the transmitter connect. The headphones automatically switch off and the Charge status LED on the transmitter lights up red. When the rechargeable batteries are fully charged, the Charge status LED turns green. 100% When not in use, place the headphones on the headphones holder to ensure that batteries are fully charged when needed. The transmitter utilizes an intelligent battery charging technology that prevents overcharging. After taking the headphones from the holder of the transmitter, the charge status LED indicates the approximate operating time of the headphones (see page 9). RS 165 | 17
