placed using the following procedure.

the cascade master unit.
The calling method is the same as ordinary calling.
See page 7 in the “Basic operation guide” (a separate
manual) for details.
2After the communication is established, call
each of the slave units connected to the
Cascade master unit.
The calling method is the same as ordinary calling.

master unit before calling the master unit in another
location.
