Precautions

On handling the unit

• 

Do not drop the unit or subject it to shock; doing so 
may cause a malfunction.

• 

Do not leave the unit in the following locations.

 

In a place exposed to extremely high 
temperatures (60°C or higher) or low 
temperatures (0°C or lower)

 

Near heat sources

 

In a place exposed to high humidity

 

In the cabin of a car with closed windows 
(particularly in summer)

 

In a place exposed to excessive dust

 

In a confined space such as a bookcase or built-in 
cabinet

• 

Do not place lighted candles on the apparatus.

• 

Do not expose the batteries installed to excessive 
heat such as sunshine, fire or the like for a long time.

• 

Do not let any solid object or liquid fall into the unit.

• 

When the cabinet becomes soiled, clean it with a 
soft dry cloth. Never use chemical solvents such as 
thinner or benzene, as they may mar the cabinet.

• 

Do not leave magnetic bank cards, magnetic 
train passes, or other cards containing magnetic 
information near the speaker. The information on 
the card may be erased by the magnet inside the 
speaker.

• 

Keep the volume at a moderate level so as not to 
harm your ears.

On splash proof performance

Although this unit is splash proof to a degree against 
exposure to a spray of rain, snow, and water, exercise 
caution in the following situations.

• 

Do not splash a large amount of water on the unit.

• 

Do not immerse the unit in water.

• 

If water is splashed on the unit or it is dropped into 
water, immediately remove the unit from the water 
and wipe moisture from the unit with a soft dry 
cloth.

• 

If water gets into the speaker, turn the speaker side 
of the unit downward and pour the water out from 
the speaker.

• 

When the 

 headphone jack or USB port is not 

used, be sure to close the terminal cover. If you do 
not close the terminal cover, the unit’s splash proof 
state will be compromised. When these terminals 
are being used with the cover open, be careful not to 
expose them to water.

• 

After the unit is exposed to water, take caution it 
does not make nearby objects wet.

On using this unit, Sony shall not be liable for any 
damage caused by smartphone memory data loss or 
inability to talk on the smartphone, loss in profit, or 
any claim from a third party.

If the unit malfunctions, do not open the cabinet. 
Contact your nearest Sony dealer.

Notes

• 

If using this unit for the first time, if it had not been 
used for a long time, or if the power has been left 
on, the battery operating time may be short even 
after charging it. In that case, charge (for more than 
a minute) and discharge the battery (using the 
radio or light) several times. The battery life will be 
restored.

• 

When you do not use this unit for a long time, 
remove the LR6 (size AA) batteries and set the 
BATT SELECTOR switch to “AA BATT” to prevent 
deterioration of the built-in rechargeable battery. It is 
also recommended to fully charge the rechargeable 
battery at least once a year using the USB AC 
adaptor.

• 

When the battery is exhausted, the sound will 
become weak or distorted, or the TUNE indicator 
will grow dark. In that case, charge the built-in 
rechargeable battery or replace LR6 (size AA) 
batteries with new ones.

• 

You cannot replace the built-in rechargeable battery.

• 

If the operating time of the radio is too short even 
after charging the unit, please contact your nearest 
Sony dealer.
