there are no parameters, then the parameter signal does
not need to be sent.

Note
● If multiple commands are transmitted, be sure to wait
for the response for the first command to come from
this unit before sending the next command.
●
If an incorrect command is sent by mistake, this
unit will send an "ER401" command back to the
computer.
●
In Standby condition (power OFF with remote
control), the unit responds to PON command only.

Consult your local Panasonic dealer for detail
instructions on command usage.
