 Actual available memory for application software includes the memory space which is used for 

factory-preinstalled applications.

FLEXIBLE  CIRCUIT  BOARD  REPAIRING
• 

Keep the temperature of soldering iron around 270 °C during 
repairing.

• 

Do not touch the soldering iron on the same conductor of the 
circuit board (within 3 times).

• 

Be careful not to apply force on the conductor when soldering 
or unsoldering.

The time below may differ depending on ambient temperature or the status of use.

Actual battery life may vary depending on settings. The estimated battery usage 

hours shown below are based on typical usage conditions with “Settings for battery 

life measurement” as shown below.

Approx. 60 Hrs

Approx. 61 Hrs

Approx. 43 Hrs

Approx. 33 Hrs

Approx. 22 Hrs

Approx. 16 Hrs

Approx. 9 Hrs

• Even if the player is turned off for an extended period, a small amount of battery 

power is still consumed. 

• Battery life may vary depending on volume setting, conditions of use and ambient 

temperature.

Brightness (*1): Default

ClearAudio+ (*2): OFF (default setting: OFF)

Equalizer (*3): OFF (default setting: OFF)

Surround sound (*3): OFF (default setting: OFF)

DSEE HX (*3)(*4): OFF (default setting: OFF)

Dynamic normalizer (*3): OFF (default setting: OFF)

OFF (default setting: OFF)

(*1)

 The maximum brightness setting shortens the battery life for continuous video playback by about 

19% compared with the default setting.

(*2)

 The [On] setting shortens the battery life about 37% compared with the [Off] setting.

(*3)

 Setting [Equalizer] to other than [Off], [Surround sound] to other than [Off], [DSEE HX] to [On] and 

[Dynamic normalizer] to [On] shortens the battery life for continuous music playback by about 70%.

(*4)

 The [On] setting shortens the battery life about 52% compared with the [Off] setting.

(*5)

 When listening to music wirelessly with [Bluetooth] set to [ON], the battery life is about 40% to 65% 

shorter than when [Bluetooth] is set to [OFF]. The battery life also differs depending on the selected 
codec.

The approximate times are based on the case in which you transfer or record only 4 

minute songs.

lowing procedure if you want to dispose of the lithium ion storage 
battery pack that is installed in the unit.

 The SPACER (BATT) has been changed in the midway of pro-

duction. There are two types of case if the battery recycle label 
has been affi xed to the SPACER (BATT), and affi xed directly to 
the lithium ion storage battery pack.

Procedure:
1. Confi rm the shape of the SPACER (BATT).
•  There is a battery recycle label, and there is no hole. (Fig. A) 

→ go to step 2

•  There is no battery recycle label, and there is a hole. (Fig. B) 

→ go to step 3

2.  Peeling off the battery recycle label from the SPACER (BATT).

 Do not use a battery recycle label that was peeled off.

3. Confi rm that the battery recycle label has been affi xed on the 

lithium ion storage battery pack.

•  Battery recycle label is not affi xed. (Fig. C) 

→ go to step 4

•  Battery recycle label is affi xed. (Fig. D) 

→ go to step 5

4. Affi x a new battery recycle label to the lithium ion storage bat-

tery pack (Fig. C).

Part No.
