2.1 Avoiding Hearing Damage
Permanent hearing loss may occur if earphones, headphones or speakers are used at high volume. To prevent this,
the volume should be set to a safe level. You can become desensitized over time to high sound levels which may then
sound acceptable yet still could be damaging your hearing. If you experience symptoms such as ringing in your ears,
please lower the volume or stop using the earphones/headphones. The louder the volume, the less time is required
before your hearing could be affected.
Hearing experts suggest the following measures to protect your hearing:
● Limit the amount of time you use earphones or headphones at high volume.
●
Avoid turning up the volume to block out noisy surroundings.
● Turn the volume down if you cannot hear people speaking near you.
To establish a safe volume level:
●
Set your volume control at a low setting.
● Slowly increase the sound until you can hear it comfortably and clearly, without distortion.
2.2 Power Supply and Batteries
The VK7 device contains one rechargeable batteriy. Battery degrades over time. Thus, the possible usage times for the
