To protect your hearing, follow these guidelines when you use 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-volume listening can lead to
permanent hearing loss.
•
Once you set the volume, do not increase it.
• Try several locations for the transmitter. Select the location that provides the best
performance.
• If you connect the transmitter to an audio source headphone jack, set the audio source's
volume control to mid-position, then adjust VOLUME on the headphones to the desired level.
• If the headphones' range decreases, you do not hear sound from the audio source, or the
headphones' POWER/BATT LOW indicator is blinking, replace the alkaline batteries or
recharge the rechargeable batteries.
• To preserve battery life, be sure to turn off the headphones when you are not using them.
• Turn off the headphones before turning off the transmitter.
• To protect your hearing, set the volume to the lowest setting before you begin listening. After
you begin listening, adjust the volume to a comfortable level.
• 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.
• You can only charge rechargeable batteries. Do not attempt to charge alkaline batteries.
• Do not connect the transmitter to your audio source's speaker output. Doing so could damage
the transmitter and audio source.
