■ Charging precaution
The battery pack, desktop holder, specified charging
equipment (sold separately), and optional accessories are
not waterproof/dustproof. Be sure to check the following
points before and after charging.
• Never charge the wet FJL21. If you charge the battery just after
the product gets wet, drain water well and wipe remaining water
off with a clean dry cloth before placing it in the desktop holder or
opening the external connection terminal cover.
• If you charge the battery with the external connection
terminal cover open, be sure to tightly close the cover
when charging is finished. We recommend using the
desktop holder to charge the battery to prevent water from
entering from the external connection terminal.
• Never charge the FJL21 if it is wet. Doing so might cause
electric shock or short circuit resulting in fire or a fault.
• Do not touch the desktop holder or specified charging
equipment (sold separately) with wet hands. Doing so
might cause electric shock.
• Do not splash water over the desktop holder and specified
charging equipment (sold separately) when using them.
Doing so might cause fire or electric shock.
• Do not use the desktop holder and specified charging
equipment (sold separately) near water such as in a
bathroom, shower room, kitchen or washroom. Doing so
might cause fire or electric shock.
■ Other precautions
• Do not immerse the product in hot spring water, water with
soap, detergent or bath salts in it. Also, do not use the
product underwater or submerge it for a long time. Doing
so might cause a fault.
• Do not attach/remove the battery pack or open/close the
external connection terminal cover when your hands are
wet or water drops stay on the surface of the FJL21.
• Heat resistance
Do not use the product in places where boiling water may
splash on it, in saunas or near hot air (e.g. hairdryer). The
product is not resistant to hot temperatures.
• Shock
This product is not resistant to shock. Do not drop the
product or subject it to shock. Also, do not jab the
earpiece, microphone, speaker or stereo earphone terminal
with a cotton swab or any sharp object. Doing so might
damage or deform the main unit and may result in
deterioration of waterproofness/dustproofness.
• Waterproof property
Do not expose the product to a water flow stronger than
the specified flow rate (i.e. 6 liters per minute from a faucet
or showerhead, at which you might even feel pain in the
skin). Doing so might cause a fault, even though the
FJL21 has a waterproof property equivalent to IPX5.
• The FJL21 does not float on water.
• Use within an ambient temperature range of 5℃ to 40℃
(Temporary use at 36℃ or higher in bathroom etc. is allowed),
and humidity range of 35% to 90%. Using in extreme hot or
cold places exceeding the range may damage them resulting
in loss of waterproofness/dustproofness.
• When the external connection terminal or battery cover is
deteriorated or damaged, the product cannot maintain its
waterproof property. In that case, contact an au shop or
Secure cell phone support center near you.
• If the product gets wet with water or other liquids with the
external connection terminal cover or the battery cover
open, the liquid may get inside the product causing electric
shocks or malfunction. Stop using the terminal, turn the
power OFF, remove the battery pack and contact an au
shop or Secure cell phone support center near you.
• Do not leave water on the earpiece, microphone, or
speaker. Calling may be disabled.
