[. . . ] KG µ CE µ . FCC Rules This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. [. . . ] Varnish or furniture polish may degrade the rubber feet of the transmitter, which could stain your furniture. Do not store your headphones on a glass dummy head, chair armrest, or similar for long periods of time as this can widen the headband and reduce the contact pressure of the headphones. Do not use abrasive cleaners. Wall mounting The transmitter is prepared for wall mounting. The required mounting hardware (screws and plugs) is not included in the delivery. 12 Connecting the transmitter (Fig. 1) Establish the necessary connections (mains unit, audio connecting cable). The ear cushions are secured to the earcups by means of a quarter turn fastener. To remove an ear cushion, turn it in the direction of the arrow until you overcome a slight resistance and lift it off the earcup. Inserting the rechargeable batteries (Fig. Attention: Observe correct polarity when inserting the batteries! Charging the rechargeable batteries For charging the batteries, place the headphones on the charging cradle of the transmitter. (The headphones automatically turn off during charging. ) The red LED "CHARGE" lights up during the charging process. If the batteries are fully charged, the transmitter automatically switches to trickle charging and the red LED "CHARGE" flashes slowly. Subsequent charging time is about the same time as the previous operating time. Always store the headphones on the transmitter to ensure that they are fully charged when they are needed. If you do not use the head-phones for extended periods of time, please remove the batteries and disconnect the transmitter's mains unit from the mains. Nearly discharged batteries will significantly reduce the sound quality. 10 minutes before the batteries are completely discharged, an acoustic warning signal is produced (two long beeps, see table on page 16). 13 ENGLISH Removing the ear cushions (Fig. This automatically activates the transmitter and the green LED "ON/OFF" lights up. If the sound source is turned off, the transmitter is automatically deactivated after approx. 3 minutes (the LED "ON/OFF" goes off).

To activate the sound retrieval system, move the slide switch "SURROUND" on the transmitter to the right. The yellow LED "SURROUND" lights up. Automatic noise reduction In addition, the transmitter features a "Noise Gate" function, which reduces hissing noise when no audio signal is transmitted (e. g. during pauses). 15 ENGLISH Meanings of the LEDs and acoustic signals Transmitter, LED ON/OFF (green) CHARGE (red) lit Status Meaning Audio signal is present, transmitter is activated Rechargeable batteries are being charged Rechargeable batteries are fully charged, transmitter has switched to trickle charging "SURROUND" function is activated Audio signal too low Audio signal too high ENGLISH lit flashes slowly SURROUND INPUT LEVEL (yellow) lit flashes slowly flashes rapidly Headphones, acoustic signals 6 short beeps Meaning No audio signal (transmitter is not activated, out of range) Rechargeable batteries are flat Manual or automatic turn-off Headphones tuned to channel 1, 2 or 3 Commentary Automatic turn-off after approx.
