Approx. 3 hours (full charge), Approx. 1.5 hours (approx. 80 %)

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

are based on typical usage conditions with “Basic setting of battery life measurement” as shown in the 

table below.

Even if your Walkman 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.

NWZ-E473 and NWZ-E474 have the model to whom the speaker is at-
tached (NWZ-E473K/E474K).
However, the model name of the main unit of WALKMAN of NWZ-
E473K and E474K are NWZ-E473 and NWZ-E474.
The setting of the fi rmware is different in the WALKMAN for single sales 
model and the WALKMAN to which the speaker is attached.
Therefore, it is necessary to distinguish whether the WALKMAN brought 
in to the repair is the WALKMAN to which the speaker is attached.

In the WALKMAN for supplied speaker model, marking label is given on 
the SUPPORT M.
Note: When you exchanged the SUPPORT M, peel off the marking label 

from the old SUPPORT M before it exchanges it, and try to paste it 
to the new SUPPORT M.
