R−button on private branch exchanges
If the telephone is connected to a private branch exchange, all the functions as-
sociated with the R−button, such as transferring calls, automatic call back, etc.,
can be used. Refer to the operating manual provided with your private branch ex-
change as to which Flash time must be set in order to use these functions. The
dealer where you purchased the exchange can provide information as to whether
the telephone will work properly with the exchange. The Flash time is set using
the menu. Refer to Page 161 for the sequence of option selections.
Access code
When using private branch exchanges, it is necessary to dial a specific number
to obtain the dialling tone for an outside line. If you have stored and activated a
number for an outside line in the handset, this number for an outside line is auto-
matically dialled before the phone numbers stored in the phone book and call
logs. Further information is provided on Page 167. Set the access code by using
the menu. Refer to Page 161 for the sequence of option selections.
Dialling pause
When using private branch exchanges, it is necessary to dial a specific number
to obtain the dialling tone for an outside line. When using some older private
branch exchanges, it takes a little time before the dialling tone becomes audible.
In the case of such private branch exchanges, a dialling pause can be inserted
after the number for an outside line in order to continue dialling directly without
having to wait for the dialling tone.
2 sec #
The actual phone number is dialled a certain time after the number for an outside
line.
The dialling pause can also be entered with the phone numbers in the
phone book.
