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 EyeMobile Plus device contains a rechargeable battery. All rechargeable batteries degrade over time. Thus the
possible usage times for the EyeMobile Plus after a full charge can become shorter over time than when the device
was new.
The EyeMobile Plus device uses a Li-ion Polymer battery.
If you are in a hot environment, be aware that it can affect the ability to charge the battery. The internal temperature
has to be between 0
℃
/32
℉
and 45
℃
/113
℉
for the battery to charge. If the internal battery temperature raises
above 45
℃
/113
℉
the battery will not charge at all.
Move the EyeMobile Plus device to a cooler environment to let the battery charge properly.
Avoid exposing the EyeMobile Plus device to fire or to temperatures above 60
℃
/140
℉
. These conditions may
cause the battery to malfunction, generate heat, ignite or explode. Be aware that it is possible, in a worst case scenar-
io, for temperatures to reach greater than those stated above in, for example, the trunk of a car on a hot day. So, stor-
ing the EyeMobile Plus device, in a hot car trunk could conceivably lead to a malfunction.
