Using the setup card while connecting the remote
control unit
When connecting the remote control unit, information can be written to
the setup card; reading information, however, is subject to the following
restrictions:
When the RM-P9 is connected
After reading from the setup card, the parameter settings on the setup
card may be different from the volume setting on the RM-P9. (The
values may, however, match by coincidence.) For this reason, there may
be a great change in the parameter setting on the setup card even if the
volume on the RM-P9 has been changed only slightly.

When the RM-B150 is connected
Even if you read the information from the setup card, the absolute value
setting on the setup card will be overwritten by the volume setting on the
RM-B150. This, however, can be avoided by setting the volume to
relative mode.
