The transmitter will automatically be ready to operate. Note that the transmitter will switch on as soon as it detects an audio signal at the AUDIO IN jacks or the • jack. 6.2 Connecting the Transmitter to Your Audio Source You may connect the transmitter to a headphones output (mini jack or 1/4” jack), LINE, or REC outputs. 6.2.1 Connecting to a Headphones Output 1. Before connecting the transmitter to your audio source, switch the audio source OFF. 2. Referring to fig. 5, plug the red RCA connector (right channel) on the supplied connecting cable into the red AUDIO IN R socket (7) and the white RCA connector (left channel) into the white AUDIO IN L socket (7) on the transmitter rear panel. 3. Connect the stereo mini jack plug on the connecting cable to the headphones output of your audio source (refer to fig. 6). 4. If the headphones output on your equipment is a 1/4” jack, plug the supplied mini jack to 1/4” adapter jack onto the connecting cable. Connect the adapter jack to the headphones output. 6.2.2 Connecting to a LINE or REC Output 1. Before connecting the transmitter to your audio source, switch the audio source OFF. 2. Referring to fig. 7, plug the red RCA connector (right channel) on the supplied connecting cable into the red LINE OUT R or REC OUT R socket and the white RCA connector (left channel) into the white LINE OUT L or REC OUT L socket on your audio source. 3. Connect the stereo mini jack plug on the connecting cable to the • jack (7) on the transmitter rear panel (see fig. 8). 6.3 Charging the Batteries in the Headphones In order to ensure the longest possible service life for the rechargeable batteries, we deliver them uncharged. Therefore, charge the supplied batteries before first operating your headphones system. The supplied batteries have been inserted into the headphones for your convenience. WARNING: If you operate the headphones on dry batteries (see section 6.4), never try to charge the batteries using the transmitter’s charging feature. This would cause serious damage to your headphone system. Dispose of spent batteries conforming to local waste disposal rules. 1. Use the POWER switch (1) to switch the headphones off. When the power is off, the POWER LED (2) will be dark. 2. Referring to fig. 11, place the headphones on the transmitter such that the charging pins (10) on the transmitter will engage the charging contacts (3) on the bottom of the left- hand earphone. The POWER ON/CHARGE LED (11) on the transmitter will ENGLISH 7 light red to indicate that the batteries in the headphones are being charged. If signal is present at the transmitter audio input, the POWER ON/CHARGE-LED (11) will light orange. The batteries will be fully charged after approximately 7 hours. (The POWER ON/CHARGE LED (11) will continue lighting red.). You may leave the headphones on the transmitter for as long as you like without risking to overcharge the batteries. Important: In order to maintain full battery capacity for as long as possible, discharge the batteries completely about once a month: Switch the headphones on and leave them outside the transmitter until the POWER LED (2) extinguishes. Press the POWER switch (1) once to switch the headphones off. Recharge the batteries as described above. 6.4 Replacing Batteries The capacity of any rechargeable battery will decrease over time. If you feel that you need to recharge the supplied batteries more often than would be convenient, you may consider replacing the batteries with new AAA size 1.2 V rechargeable or 1.5 V alkaline dry batteries. 1. Remove the ear pad from the left-hand earphone as shown in fig. 9. 2. Remove the old batteries. 3. Referring to fig. 10, insert the new batteries into the battery compartment (4). Make sure to align the batteries with the polarity marks inside the battery compartment. 4. Replace the ear pad on the earphone aligning the four pins on the ear pad with the matching openings in the earphone base plate. 6.5 Setting Up the System 1.
