Orient the SPEAKER so that its lead wires come to the left side as shown below and attach it to the
U-CASE. (In the picture, note that the CUSHION/SPEAKER is intentionally removed to show you the
position of the lead wires. In reality, it is attached.)
In this case, raise the antenna cable to prevent it from being caught and set the SPEAKER. Then, return
the antenna cable as it was.
When the SPEAKER is new, assemble it after peeling off the release paper of the W-TAPE/SPEAKER,
and then attach the CUSHION/SPEAKER after assembling the HOLDER/SPEAKER.
