3.8.1 BGM Input
Input impedance: 50 K (unbalanced)
Input level: -10dB max.
Output level: 100mW
(a) Remove the short bar connected to the terminal.
(When BGM is not employed, the short bar should be kept on the terminal.
If the short bar is not replaced, a humming sound will be heard from the
station.) The short bar is referred to on page 3.
(b) Connect the BGM equipment. (Be sure to use the type of BGM equipment
which meets the input specifications. Since the level adjustment cannot be
controlled in the exchange, the BGM equipment must have an output
level adjuster.)
(c) After installation, adjust the output level of the BGM through the speaker.
If the input is excessive, there will be distortion.
3.8.2 All-Call Paging Output
Output impedance: 600 (unbalanced)
Output level: 0dBm
(a) Connect a paging amp which matches the output specifications.
(b) Test the paging output level and adjust to eliminate feedback. (Placing the
speaker too close to the station sometimes causes feedback.)
3.8.3 Remote Control Output
Output signal: no voltage contact
Contact capacity: 125VA
The program switch on the CPU-16 allows selection of either of the
following 2 functions for remote control.
1. Door Remote Control
Every master station can be used as a remote control device for the door
opening function. Pressing buttons
wherein the door can be opened.
2. Power On/Off Remote Control

allows a 4-second interval
When the system is used in conjunction with a PA amplifier for the
external all-call function, the power switch of the PA amplifier can be
turned on/off with the relay built into the system. Pressing buttons
and
invokes the make-contact and the all-call function until it is cancelled
