Specifications - Sony SRS-XB21 Reference Manual

The waterproof and dust proof performance of the system 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 avoid deterioration of waterproof and dust proof performance
Check the following and use the system correctly.
 The system 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 system or subjecting it to mechanical shock may cause deterioration of the
waterproof and dust proof performance.
 Do not use the system in a location where large amounts of water or hot water may splash on it.
The system does not have a design that is resistant to water pressure. Use of the system in a
location where high water pressure is applied, such as under running water or 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 system directly. Also, never use the system 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 system, 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 system as a result of water or dust particles entering the system.

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

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.
