To avoid deterioration of waterproof and dust proof performance
Check the following and use the unit correctly.
The unit passes the drop test from 1.22 m on plywood of 5 cm thickness conforming to MIL-STD
810 F Method 516.5-Shock. However, this does not guarantee no damage, no breakdown, or
waterproof and dust proof performance in all conditions. Deformation or damage from dropping
the unit or subjecting it to mechanical shock may cause deterioration of the waterproof and dust
proof performance.
This unit does not have a design that is resistant to water pressure. Use of the unit in a location
where high water pressure is applied, such as in the shower, may cause a malfunction.
Do not pour high-temperature water or blow hot air from a hair dryer or any other appliance on
the unit directly. Also, never use the unit in high temperature locations such as in saunas or near
a stove.
Handle the cap with care. The cap plays a very important role in maintenance of the waterproof
and dust proof performance. When using the unit, 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 dust proof performance may deteriorate and may cause a
malfunction of the unit as a result of water or dust particles entering the unit.

How to care for the unit
Although the fabric part of the unit has water repellent treatment applied, you can use the unit
more comfortably and for a longer period of time by following the maintenance procedure below.
If the surface of the unit gets dirty in the following cases, wash the unit with fresh water (tap
water, etc.) promptly to remove the dirt. Leaving dirt on its surface may cause the fabric part to
discolor or deteriorate, or the unit to malfunction.
Ex.
When salt, sand, etc. is stuck on the unit after using it on a beach, pool side, etc.
When the unit is stained with foreign substances (sunscreen, suntan oil, etc.)
If the unit gets wet, wipe off the moisture using a dry soft cloth immediately. In addition, dry the
unit in an airy place until no moisture remains.
The sound quality may change when water enters the speaker section of the unit. It is not
malfunction. Wipe off the moisture on its surface, and put the unit on a dry soft cloth with the
fabric part facing down to drain the collected water inside the unit. Then, dry the unit in an airy
place until no moisture remains.
Note
If the surface of the unit gets dirty, do not use detergent, thinner, benzine, alcohol, etc. to clean
the unit because it will affect the water repellent function of the fabric part of the unit.
Especially in cold regions, be sure to wipe off the moisture after using the unit. Leaving moisture
on its surface may cause the unit to freeze and malfunction.
If sand grains, etc. enter the fabric part of the unit, remove them carefully. Never use a vacuum
cleaner, etc. on the unit. It may cause damage of the speaker unit.

LDAC is an audio coding technology developed by Sony that enables the transmission of
High-Resolution (Hi-Res) Audio content, even over a BLUETOOTH connection. Unlike other
BLUETOOTH compatible coding technologies such as SBC, it operates without any down-
conversion of the Hi-Res Audio content*
7
, and allows approximately three times more data*

than those other technologies to be transmitted over a BLUETOOTH wireless network with
unprecedented sound quality, by means of efficient coding and optimized packetization.
