Notes while swimming in a pool or the ocean
Do not use your Walkman in a crowded place or in circumstances which an inability to hear surrounding sounds would be
dangerous.
When you use your Walkman in public or private swimming facilities, follow the rules of that facility.
The earbuds create a seal in your ear canal. Thus, there is a risk of damage to your ears or eardrums if strong pressure is
applied to the earbuds, or the earbuds are removed suddenly from your ears. Due to this risk, do not do vigorous exercise,
dive into a swimming pool, etc., while wearing your Walkman.
Do not pour hot water directly on your Walkman and do not blow hot air from a hair dryer, etc., directly on the Walkman.
Never use the Walkman in high - temperature locations such as in saunas or near a stove.
Do not use or leave your Walkman in the following types of environment:
in high temperature locations with a temperature above 45 °C (113 ºF) such as under the blazing sun, in a car, in warm
water or other high temperature and high humidity locations
in a cold locations with a temperature below –5 °C (23 ºF)
If you cannot avoid using your Walkman in a location exposed to direct sunlight, cover your Walkman with a towel, etc.
The sound volume is lower with Swimming earbuds than with standard -type earbuds. Increase the volume as needed.
When you replace Swimming earbuds with the standard -type earbuds, the sound becomes louder. Adjust the volume so as not
to hurt your eardrums.
Your Walkman may detach and fall during vigorous exercise, etc.
Your Walkman will sink if dropped in water.
Radio waves do not transmit through water. You cannot perform the following operations via a Bluetooth connection
underwater.
Listening to music on a smartphone.
Answering a call.

Notes on Ambient Sound Mode
When the Swimming earbuds are attached, ambient sound cannot be heard as well as when Standard -type earbuds are
attached.
Ambient sounds cannot be heard well after using your Walkman in a pool or the ocean. Repeatedly pat the parts around the
buttons of your Walkman softly against a dry cloth about 30 times. Then place your Walkman on a dry cloth at room
temperature for 2 to 3 hours to ensure it is completely dry before the next use.

What is Ambient Sound Mode?
Ambient Sound Mode uses the microphones built into the left and right sides of your Walkman to allow you to hear ambient sound
even while wearing headphones. Pay attention to the sounds around you to enjoy listening to music safely.
Note
Ambient Sound Mode allows you to hear ambient sound even while wearing headphones. However, note that this mode does not enable you to
hear all sounds around you. Ambient sound may not be heard well depending on the surrounding environment, type of the music being played on
your Walkman, or the volume level. Be very careful when using the Walkman in places where an inability to hear ambient sound would be
dangerous (such as on roads where there is car or bicycle traffic).
Ambient Sound Mode may not function properly if you use your Walkman with earbuds that do not fit your ears. Use earbuds of an appropriate size

The built - in rechargeable battery becomes depleted quickly even after the
Walkman is fully charged.
If the battery life becomes half as short as normal, consider replacing the battery.
The battery life depends on the conditions of use, settings, and ambient temperature.
Furthermore, the following operations will deplete the battery more quickly than continuous use of the Walkman.
Turning the Walkman on or off frequently.
Changing the Walkman settings frequently.
Charging and discharging the battery repeatedly.
This will gradually decrease the capacity of the battery. As a result, the battery may become depleted quickly even after it is
fully charged.
To replace the battery, contact the nearest Sony dealer or Sony Service Center.
The battery can be charged approximately 500 times on average.
However, the battery lifespan depends on the temperature and usage environment.
When the life of a fully charged battery becomes half as short as normal, consider replacing the battery.
To replace the battery, contact the nearest Sony dealer or Sony Service Center.
Do not replace the battery yourself. The battery is built into the Walkman. Battery replacement requires professional knowledge
and skills.
