Performing connection from the primary cassette
In order to achieve connection between the external cassette of the primary exchange
and any given uniphone, one should select its number from the keyboard. Then the
primary exchange sends it over to all the secondary exchanges and through their

uniphones receiver, secondary exchange transmits the connection to the primary
cassette. Control of the code lock function is performed according to the same
principles.
Local connections performed by secondary cassettes
During the time of connection between the primary cassette and a uniphone connected
to one of the secondary cassettes, the remaining secondary exchanges can perform
local connections. The secondary exchange which performs connection with the
primary exchange is blocked for local connections, which is signaled by the display
reading [OFF].
During the performance of local connection by a secondary exchange, it is possible
to initiate code lock function initiated by the primary exchange.
