You must use a Class 2 power source that supplies 12 volts DC and delivers at least 250mA. Its center tip must be set to positive and its plug must fit the transmitter's DC IN 12V jack. The supplied adapter meets these specifications. Using an adapter that does not meet these specifications could damage the transmitter or the adapter.

Always connect the AC adapter to the transmitter before you connect it to AC power. When you finish, disconnect the adapter from AC power before you disconnect it from the transmitter.

Use only fresh batteries of the required size and recommended type.

Do not mix old and new batteries, different types of batteries (standard, alkaline, or rechargeable), or rechargeable batteries of different capacities.

If you do not plan to use the headphones for a week or longer, remove the batteries. Batteries can leak chemicals that can destroy electronic parts.

Many factors affect the range of your system. To achieve the best performance:

Position the transmitter as far as possible from other electronic devices such as TVs, receivers, or VCRs. Radio interference from these devices could affect your system’s performance.

Position the transmitter away from large metal objects, as these could block your transmitter’s signals.

Try several locations for the transmitter. Select the location that provides the best performance.

Your system’s overall performance depends on your home’s construction method, the other devices near the system, and other radio frequency sources in your home (such as cordless telephones).

You can connect the transmitter to your audio source’s left and right audio output jacks or the headphone jack. .

1.Connect one end of the supplied audio patch cord to the transmitter’s audio jacks (white plug to L AUDIO IN and red plug toR AUDIO IN).

2.If you are using the audio source’s output jacks, connect the white and red plugs at the other end of the patch cord directly to the audio source’s corresponding left (white) and right (red) audio jacks.

If you are using your audio source’s stereo headphone jack, connect the patch cord’s white and red plugs to the white and red phono jacks on the Phono to 1/8-inch supplied adapter.

3.If your audio source has a 1/8-inchheadphone jack,insert the adapter’s 1/8-inch stereo plug into the audio source’s HEADPHONE jack.

To protect your hearing, follow these guidelines when you use your headphones.

Set the volume to the lowest setting before you begin listening. After you begin listening, adjust the volume to a comfortable level.

Do not listen at extremely high volume levels. Extended high-volumelistening can lead to permanent hearing loss.

Once you set the volume, do not increase it. Over time, your ears adapt to the volume level, so a volume level that does not cause discomfort might still damage your hearing.

You can use multiple sets of headphones with each transmitter. We do not recommend using multiple transmitters in the same area.

1.Press POWER on the transmitter. The transmitter’s POWER indicator lights red. Turn on the audio source.

2.To turn on the headphones, slide POWER away from the headband. The POWER/BATT LOW indicator lights red.

3.Put on the headphones and adjust VOLUME to the desired listening level.

4.To turn off the headphones, slide POWER toward the headband.

5.To turn off the transmitter, press the power switch. The POWER indicator turns off.

±"016'"±"

If the POWER/BATT LOW indicator is blinking, the battery level is low and you must replace the alkaline batteries or recharge the rechargeable batteries before use.

If you connected the transmitter to an audio source’s headphone jack, set the audio source’s volume control to its midposition, then adjust VOLUME on the headphones to the desired level.

To preserve battery life, be sure to turn off the headphones when you are not using them.

If reception is poor even when the batteries are fully charged and you are near the transmitter, try moving the transmitter to a higher location or moving it away from the audio source.

If you are not using the transmitter, disconnect the adapter.

Turn off the headphones before turning off the transmitter.
