35 °C (41 °F and 95 °F).
If the built-in battery is under a high load during charging, charging stops for safety. In such a case, turn down the volume or stop
the playback.
If you are playing music while the speaker is charging or in a location with high ambient temperatures, the volume may be
automatically adjusted for safety reasons.
Charging from a USB hub is only guaranteed when you use a self-powered USB hub that carries an authorized logo.

Notes on waterproof and dustproof features
On waterproof and dustproof performance of the speaker
The speaker, with the cap fastened securely, has a waterproof specification of IPX7 (*1) as specified in “Degree of
protection against water immersion” of the IEC60529 “Ingress Protection Rating (IP Code)” (*3), and a dustproof
specification of IP6X (*2) as specified in “Degrees of protection against solid foreign objects” (*3).
Liquids that the waterproof performance specifications apply to
The waterproof performance of the speaker is based on our measurements under the conditions herein described. Note
that malfunctions as a result of water immersion or dust intrusion caused by misuse by the customer are not covered by
the warranty.
To maintain waterproof and dustproof performance
Carefully note the precautions below to ensure proper use of the speaker.
The speaker passes the drop test from 1.22 m (4.0 ft) on plywood of 5 cm (1.97 in) thickness conforming to MIL-
STD810H Method 516.8-Shock. However, this does not guarantee no damage, no breakdown, or waterproof and
dustproof performance in all conditions. Deformation or damage from dropping the speaker or subjecting it to
mechanical shock may cause deterioration of the waterproof and dustproof performance.
Do not pour high-temperature water or blow hot air from a hair dryer or any other appliance on the speaker directly.
Also never use the speaker in a place subject to high temperatures, such as in a sauna or near a heat source.
Handle the cap on the rear side of the speaker with care. The cap plays a very important role in maintenance of the
waterproof and dustproof performance. When using the speaker, make sure that the cap is closed completely. When
closing the cap, be careful not to allow foreign objects inside. If the cap is not closed completely the waterproof and
dustproof performance may deteriorate and may cause a malfunction of the speaker as a result of water or dust
particles entering the speaker.
Applicable fresh water, tap water, pool water, salt water
Not
applicable
liquids other than the above (soapy water, water with detergent or bath agents, shampoo, hot spring
water, etc.)
(*1) IPX7 equivalency: The speaker has been tested to and maintains its operability when gently submersed in water to a depth of 1 m (3.2 ft)
and left for 30 minutes.
(*2) IP6X equivalency: The speaker has been tested to and continues to block dust after stirring for 8 hours in a testing device which contains
dust particles that are up to 75 μm in diameter.
(*3) The supplied accessories and the connectors of this speaker (USB) are neither waterproof nor dustproof. To reduce the risk of fires or
electric shocks, do not expose the speaker to water or droplets while using any connectors (USB).

How to care for the speaker
You can use the speaker and the shoulder strap more comfortably and for a longer period of time by following the
maintenance procedure below.
If the surface of the speaker gets dirty in the following cases, wash the speaker with fresh water (tap water, etc.)
promptly to remove the dirt. Leaving dirt on its surface may cause the fabric part or the passive radiator section to
discolor or deteriorate, or the speaker to malfunction.
Ex.
When salt, sand, etc. is stuck on the speaker after using it on a beach, pool side, etc.
When the speaker is stained with sweat or foreign substances (sunscreen, suntan oil, etc.)
“a” in the illustration indicates the location of the passive radiator section of the speaker.
Leaving the speaker wet causes limescale or mold to develop, resulting in soiling of the speaker. After using the
speaker in wet conditions, it is recommended that you wipe off water droplets all the speaker surfaces and let the
speaker dry in a well-ventilated location.
The sound quality may change when water enters the speaker or passive radiator section of the speaker. It is not
malfunction. Wipe off the moisture on its surface, and put the speaker on a dry soft cloth to drain the collected water
inside the speaker. Then, dry the speaker in an airy place until no moisture remains.
Note
If the surface of the speaker gets dirty, do not use detergent, thinner, benzine, alcohol, etc. to clean the speaker because it will
affect the water repellent function of the fabric part of the speaker.
Especially in cold regions, be sure to wipe off the moisture after using the speaker. Leaving moisture on its surface may cause the
speaker to freeze and malfunction.
If sand grains or other particles enter the fabric, the inside of the storage caps, or other parts of the speaker, remove them
carefully. Never use a vacuum cleaner or similar tool on the speaker. It may cause damage of the speaker section or other parts
of the speaker.

About the BLUETOOTH wireless technology
The BLUETOOTH wireless technology is a short-range wireless technology that enables communication between digital
devices, such as smartphones and computers.
Supported version and profiles of the BLUETOOTH standard
A BLUETOOTH profile is a set of functions standardized for every characteristic of BLUETOOTH devices. The speaker
supports the following version and profiles of the BLUETOOTH standard.
Supported BLUETOOTH version:
BLUETOOTH standard, version 5.2
Supported BLUETOOTH profiles:
A2DP (Advanced Audio Distribution Profile): Enables transmission and reception of high-quality music contents.
AVRCP (Audio Video Remote Control Profile): Enables volume adjustment and operations to play/pause music and
skip to the beginning of the next/current track.
HFP (Hands-free Profile) (*): Enables hands-free phone call making and smartphone or mobile phone operations.
HSP (Headset Profile) (*): Enables phone call making and smartphone or mobile phone operations.
Maximum communication range
Use the BLUETOOTH wireless technology between the speaker and a device that are located within about 30 m (98.4 ft)
from each other.
Maximum communication range may shorten under the following conditions.
There is an obstacle such as a person, metal, or wall between the speaker and BLUETOOTH device.
A wireless LAN device is in use near the speaker.
A microwave oven is in use near the speaker.
A device that generates electromagnetic radiation is in use near the speaker.
Frequency band
2.4 GHz band (2.400 0 GHz - 2.483 5 GHz)
Corresponding content protection
SCMS-T
Transmission range (A2DP)
20 Hz - 20 000 Hz (Sampling frequency 44.1 kHz)
Interference from other devices
Because BLUETOOTH devices and wireless LAN (IEEE802.11ax/b/g/n) use the same frequency (2.4 GHz), microwave
interference may occur and result in communication speed deterioration, noise, or invalid connection if the speaker is
used near a wireless LAN device.
Interference to other devices
(*) If the smartphone or mobile phone with the BLUETOOTH function supports both HFP and HSP, use HFP (Hands-free Profile).
90
Microwaves emitting from a BLUETOOTH device may affect the operation of electronic medical devices. Turn off this
speaker and other BLUETOOTH devices in the following locations, as it may cause an accident:
in hospitals, near priority seating in trains, locations where inflammable gas is present, near automatic doors, or near
fire alarms.
Note
Depending on the network environment, there may be an interruption at the high bitrate transmission.
To be able to use the BLUETOOTH function, the BLUETOOTH device to be connected requires the same profile as the
speaker’s. Note also that even if the same profile exists, devices may vary in function depending on their specifications.
Due to the characteristic of BLUETOOTH wireless technology, the sound played on the speaker is slightly delayed from the sound
played on the BLUETOOTH device while talking on the telephone or listening to music.
The speaker supports security capabilities that comply with the BLUETOOTH standard to provide a secure connection when the
BLUETOOTH wireless technology is used, but security may not be enough depending on the setting. Be careful when
communicating using BLUETOOTH wireless technology.
We do not take any responsibility for the leakage of information during BLUETOOTH communication.
A device featuring the BLUETOOTH function is required to conform to the BLUETOOTH standard specified by the Bluetooth SIG,
Inc. and be authenticated. Even if the connected device conforms to the above mentioned BLUETOOTH standard, some devices
may not be connected or work correctly, depending on the features or specifications of the device.
Noise or sound interruption may occur depending on the BLUETOOTH device connected with the speaker, the communication
environment or the usage environment.
A device with a built-in radio or tuner cannot be connected to the speaker via a BLUETOOTH connection since noise may occur in
broadcasts.
Locate the speaker farther away from a TV, radio or tuner, etc. since noise may occur in broadcasts.
