[TS-901 Top]
1. Monitor speaker
Speech signals from other Conference units and
other audio signals from the Central unit are output
from this speaker. (Refer to the table below.)
Model Output signal
TS-901 Base language or Translation language
Note: Switchable by the Monitor selector
switch (17).
TS-801 Base language
Use the right-side Monitor Volume Control (16) to
adjust the volume. No sound is output from the
speaker of the unit in use while speaking.
2. Microphone
Use either the TS-903 (Standard) or TS-904 (Long)
dedicated microphone.
3. Microphone in-use indicator
Lights when the microphone is turned on (for
speech) and flashes when the battery level is low.
4. Infrared emitter/detector
The device used to transmit and receive infrared
communication signals is built inside this panel.
Note
Never place any object that could block infrared
signal access to this part of the unit, as this would
prevent the unit from transmitting or receiving its
required infrared signal.
5. Voting keys (TS-901 only)
Use these keys to start, end, and cast voting. The
voting status indicator is provided on each key.
6. Speech indicator
Remains lit while the microphone is in use (during
speech). The indicator flashes when the unit is out
of the communications service area.
7. Talk key
When this key is pressed, both the Microphone In-
Use indicator (3) and the Speech indicator (6) light,
and the microphone turns on. Pressing this key
again turns off both indicators and the microphone.
8. Priority speech key
Gives speaking priority to the current speaker.
When this key is used for speech, no other delegate
units can be used. Also, only the current speech
made with the Priority speech key is output at the
Central Unit’s recording and line outputs.
The key has 2 different operating modes, PTT and
ALT, which can be selected with the Priority speech
key operation setting switch (14).
• When PTT mode is selected, the microphone
only turns on while the key is pressed, during
which time the Speech (6) and Microphone in-
use (3) indicators remain lit.
• When ALT mode is selected, pressing the key
turns on the microphone and causes the Speech
(6) and Microphone in-use (3) indicators to light.
Pressing the key again turns off the microphone
and these indicators.
If Chime is set to sound, a chime tone sounds when
the key is pressed. For the chime setting, use the
Priority chime mute switch (12).
9. Power indicator
Lights when the power is switched ON.
This indicator also flashes when the battery level
is low or the unit is outside the communications
service area.
Note: No microphone is supplied with the TS-901/801.
