6 OPERATIONS
Calling and receiving
sub, door or master
To call a TB-SE sub, the other master or audio door station pick up
handset and depress a station-select button. When called by
tremolo tone, pick up and depress the LED-lit select button. LED
remains on while in communication. Communicating TC-M is
notified of a call with a lit LED only. The audible call tone will
resume when the handset is hung up.
Receiving a call from audio IE/IF door station
When the door station places a call with call button, a tremolo tone
is activated on the TC-M, which stays on approx. 40 seconds. The
master replies by selecting the station button that is lit. At the door
station, when selected, a pretone is heard, unless it is muted at the
TB-AD1, 10 adaptor.
“Transfer” allows two TB-SE subs to communicate with each other
When a master receives a call from sub A, requesting transfer of
call, TC-M leaves sub A waiting, pressing a sub B select button.
When sub B picks up the call (sub A hears a busy tone), TC-M
depresses Transfer switch.
TC-M then reselects waiting sub A with red LED on. Three parties
are on the line, and TC-M may hang up.
★ Door-to-master or master-to-master calls are not transferrable.
★ If transfer LED is lit when a transfer is not being made, it can be
cleared by pressing “transfer” switch.

TC-M places a buzzer-activating call to a TB-SE sub
Buzzer sounds continuously at TB-SE sub, in
addition to ordinary tremolo. Pick up on the
TB-SE station, that the buzzer is connected to.
Adjusting receive and call tone volume
possible.
A call from TB-SE subs that are connected to two masters activates
tremolo tone at both masters. When the controlling TC-M is busy,
the other TC-M may pick up. In this case, the sub hears both
tremolo and busy tones.
★ Dual-master has an operation that, when TC-M1 places a call to
either TC-M2 or a common TB-SE that is already in
communication, the talk line is connected among 3 parties.
It reduces communication volume. One party should hang up to
restore normal volume.
To call TC-M master, simply pick up and it rings TC-M with tremolo
tone, which continues ringing until the call is answered. Intermittent
tone means the master is occupied. Hang up or continue to hold.
When called by tremolo tone, simply pick up.
7 TECHNICAL PRECAUTIONS-
★ The power switch is located on back panel of TC-M console, which should be placed ON, except for
special occasions. If the system malfunctions, turn off and on TC-M master, by which the system
may reset itself. Possible causes are; power supply is unplugged, connecting wires are loosened or
shorted. Do not attempt to open TC-M equipment nor change wiring. Ask qualified personnel.
★ At end of each communication, be sure to place handset in cradle properly. If not, TC-M master or
TB-SE sub will not hear the call tone.
★ The TC-M is rated to operate at temperatures between CPC - +40°C (32 <> F - 104°F).
★ Clean the TC-M equipment with a soft cloth dampened with neutral household cleanser. Never use
any abrasive cleaner or cloth.
