CHAPTER 3. CONVENIENT FUNCTIONS
[Exceptions]
(1) When the designated receiving station (example: 93) is busy, all succeeding calling parties must wait.
(Even Station 93 is also registered for Busy Call Forwarding, only the first transfer attempt to this station is
made, followed by no further attempts. The waiting stations wait until the line of Station 93 becomes free.)
As soon as Station 93 finishes its conversation, the next calling party is automatically put through to that
station. When the line of the original station (example: 92) is freed while Station 93 is still busy, the calling
party is connected to Station 92 without being transferred.
(2) The designated receiving station (93) can directly call the original station (92) without interference from the
call forwarding function.
(3) The Busy Call Forwarding function is disabled when the designated receiving station has already been
registered for Call Forwarding.
(4) The Busy Call Forwarding function does not interfere with a substation call to a Group Call representative
station that is registered for Busy Call Forwarding. (The group call designation is given priority.)

Any master station can scan a designated group of substations for audio monitoring of each substation.
(See the figure on the next page.)
[System pre-programming]
(1) Substations to be monitored (up to 16) can be registered for each master station in system programming.
(2) Monitor interval times of 1 – 99 seconds (in 1 second units) for each master station can be registered in

Pressing the [#] key advances monitoring by one substation.
(3) Scan BACK
Pressing the [ ] key reverses monitoring by one substation.
