• Location outside the allowed operating tem­perature range (0°C ~ 40°C) where the tem­perature may become extremely hot or cold.

• Location outside the allowed operating humid­ity range (30% ~ 80%) where the humidity is
high.

• Location with strong magnetic force such as
from a transformer, motor, etc.

• Location with presence of electric waves such
as from a transceiver, mobile phone, etc.

• Location that is dusty or sandy.

• Location with strong vibrations.

• Location with condensation.

• Location where radiation, x-ray or corrosive gas

is generated.

Handling

■ To prevent the internal temperature from rising,
do not stack units when using.

■ Do not place the unit on its side.

■ Handle the unit with caution and do not apply ex-

cessive force.

■ Wipe the unit with a soft cloth.
The surface may fog or even melt when wiped
with benzene or paint thinner. For stubborn dirt,
use neutral detergent diluted in water and then
dry wipe.

■ To completely cut off the power, disconnect the
power cable from the wall outlet or remove the
power cord from the AC inlet (AC IN) of the unit.

■ About the echo canceller
The echo canceller of the unit is provided for the
prevention of howling. However, repeated echo­ing of sound other than from a DM-NC40 may not

disturbed or noise may be heard. In this case, try
the following:

• Place the unit away from radios and televisions
or change the direction of the unit.

• If an indoor antenna is used, change the direc­tion or the location of the antenna.

• Use a wall outlet other than the one used for
radios, televisions, etc.

•

Install a commercially-available noise filter be­tween the wall output and power plug.

1-1 Connection Examples (Continued)

Caution when connecting different modes

For teleconference application, set units to Teleconference mode. For remote monitoring application, set units to Camera/Monitor
mode. Connecting units in different application modes will result some problems as following:

Teleconference mode - Monitor mode

Teleconference side: Audio of the monitor side is played back. Video will not be played back.
Monitor side: Video and audio of the teleconference side are played back.

Teleconference mode - Camera mode

Teleconference side: Video and audio of the camera are played back.
Camera side: Audio of the teleconference side is played back.

Teleconference mode - ISMA Server mode

Teleconference side: Video is played back and audio will be noise.
Streaming side: No playback

Monitor mode - ISMA Server mode

Monitor side: Video is played back and audio will be noise
Streaming side: No playback

Camera mode - ISMA Server mode

Observing the video and audio using another DM-NC40 unit (observer mode)

Observing stream is available by connecting another DM-NC40 unit to working DM-NC40.

• Camera mode accepts observing at the time of shipment. For teleconference mode, a setting change using

API is required to accept observing. ( Page 54)

Remote Monitoring system (Camera mode and Monitor mode)

Observing is available by connecting from Monitor mode to Camera mode that is connected already to another Monitor
mode.

(At this time, ENCODE display lamp: OFF, DECODE display lamp: ON, SELECT button light: OFF (operation disabled),
PinP button light: OFF (operation disabled) on the observing unit.)

* The automatic recovery feature does not work with observing unit. Please reconnect.

Teleconference system (Teleconference mode and Teleconference mode)

After observing is enabled by API, observing is available by connecting from teleconference mode to teleconference
mode that is connected already to another teleconference mode.

(At this time, ENCODE display lamp: OFF, DECODE display lamp: ON, SELECT button light: OFF (operation disabled),
PinP button light: OFF (operation disabled) on the observing unit.)

When connecting different modes

 See “Caution when connecting different modes”, above.
