Operating the Monitor
Sensitivity to ambient noise, voice operated transmission (VOX) and ECO mode
The baby monitor combines two modern technologies: voice operated transmission (VOX) and ECO
mode.
The voice activation (VOX
camera to the monitor immediately a voice or sound is detected. If no voice or sound is detected for
longer than one minute, transmission is automatically interrupted.
There is a slight delay in the transmission before the monitor can reproduce the voice/sound
and picture.
ECO mode represents a special transmission technology. In ECO mode, the baby monitor system
transmits with considerably reduced transmission power or radiation while simultaneously increasing
the receiver sensitivity. Voice activation (VOX) is active in ECO mode. When sounds are detected,
ECO mode is automatically deactivated. The display then transmits the image from the camera.
In order that the equipment can operate in ECO mode, you must use the SENSITIVITY" menu option
to define whether the camera should operate with a low, medium or high sensitivity; see Menu
Structure, Page 62. Only when one of these three settings is set can the baby monitor switch to ECO
mode following a short delay when no sounds are detected. The message ECO Mode activiated"
then appears in the display. The display then automatically switches to show the image from the
camera when a sound at or above the set sensitivity is detected.
A low sensitivity means that the camera reacts to quiet sounds. A high sensitivity means that the
camera only reacts to louder noises. Select the setting required according to the ambient noise. Many
ambient noises necessitate a high sensitivity.
If the message ECO Mode activiated" appears in the display as a result if this setting, press
the Monitoring/Speak button to restore the image from the camera to the display.
If the setting is OFF", voice activation (VOX) is deactivated. The unit cannot switch to ECO mode.
Temperature display
The camera unit determines the temperature of its immediate surroundings by means of a temperature
sensor and indicates it in the icon bar of the monitor display. Use the menu to select whether the tem-
perature display and information should be in degrees Celsius or Fahrenheit; see Menu Structure,
Page 63.
It is also possible to activate visual and/or acoustic alert signals should temperatures rise above or
drop below defined upper and lower temperature limits; see Page 69 (Temperature alarm).
Language
The menu guidance is available in 10 different languages; see Menu Structure, Page 62.
