General Description
The HF-200M desk-top/surface-mounted type master station
is designed to operate in conjunction with the TOA fully
electronic exchange, which features a microcomputer with a
memory for stored program control. The HF-200M can com-
municate with all other master stations and substations in
the system. Each master station is equipped with 12 dialing
key pad, a press-to-talk bar, a privacy switch for refusing
incoming calls, an in-use lamp for eavesdropping protection,
a pre-adjustable volume control for microphone sensitivity,
output terminal to connect an external speaker, a built-in
station directory, and a 2-stage selector switch and a pre-
fixed volume control for adjustment of the station speaker
sound level. The HF-200M permits handsfree conversation
as well as private conversation by handset. The station base
speaker is automatically disconnected when the handset is
lifted, providing a more private conversation. The YC-200
substation panel is designed to convert the HF-200M master
station to substation by attaching it on the station key pad.
