CHARGING
To charge the earphones, place them in the
charging case, wait for white LED to turn RED
and close the lid. Open the case to check
if the red LED has turned off. If the LED is
off, earphones are fully charged. Charging
time is approximately 1.5 hours for 6 hours
of playtime. A fully charged case provides 5
extra earphone charges when on-the-go. The
number of lights indicates the charging case
battery status when the earphones are placed
in the case. 3 lights = 67-100% charged,
2 lights = 34-66% charged, 1 light = 1-33%
charged, 0 lights = 0% charged. Charge
the case using the USB-A to USB-C cable
connected to a computer or wall charger. Each
indicator at the back of the charging case
flashes white when charging and turns solid
white when fully charged. Charging time is
approximately 2 hours.

PRECAUTIONS
Do NOT use the earphones at a high
volume for any extended period.
To avoid hearing damage, use your
earphones at a comfortable, moderate
volume level.
Turn the volume down on your device
before placing the earphones in your
ears, then turn the volume up
gradually until you reach a
comfortable listening level.
Do NOT use your earphones while
driving or at any time the inability to
hear surrounding sounds may present
a danger to yourself or others.
The charging case and earphones
shall not be exposed to excessive
heat such as sunshine, fire or the like.
Focus on your safety and that of
others if you use the earphones
while engaging in any activity
requiring your attention, e.g., while
riding a bicycle or walking in or near
trac, a construction site or railroad,
etc. Remove the earphones or
adjust your volume to ensure you can
hear surrounding sounds, including
alarms and warning signals.
Do NOT use the headphones as
aviation communication headsets
except in case of emergency. No
incoming audio will be heard with
a discharged or improperly installed
battery. This could result in the
potential of missed communications
while piloting an aircraft. Extremely
loud ambient noise levels common
to many propeller-driven aircraft may
impair your ability to receive incoming
audio communications, particularly
during takeoff and climb out.–
Mezger AC-1 earphones are not
engineered for noise conditions,
altitude, temperature or other
environmental conditions common in
non-commercial aircraft,
resulting in possible interference to
critical communications.
Do NOT place naked flame sources,
such as lighted candles, on or near
the product.
Do NOT make unauthorized alterations
to the product; doing so may
compromise safety, regulatory
compliance, system performance, and
may void the warranty.
In the event of a battery leaking, do
not allow the liquid to come in contact
with the skin or eyes. If contact
has been made, wash the affected
area with copious amounts of water
and seek medical advice.
