ECDIS Status / Indicator: (optional factory standard)
For units that have been factory ECDIS calibrated the text “ECDIS” will illuminate in green constantly as long as the
unit is powered. The “+” and “-” symbols will illuminate in red when the Brightness/Brillance is adjusted either above or
below ECDIS factory calibration point.
To be able to stay within ECDIS calibrated range, please assure that both the “+” and “-” are not illuminated and that
“ECDIS” text remains illuminated during operation. Note that by touching these symbols no action will be performed or
has been assigned.
Action Indicators:
HDD = Whenever there is a storage device activity (HDD/SSD read or write operations) this area will
illuminate and blink accordingly in sync. with the read/write operations while the unit is powered.
Note that by touching this symbol no action will be performed or has been assigned.
SERVICE = Reserved for future use, no built-in function defined.
Buzzer:
Only functional for units ordered with Buzzer functionality. The location of the buzzer hole (physical hole in glass) is
barely visible to the eye. Touching this area will naturally mute buzzer sound or in some cases make it lower or change
audible frequency. In no circumstances should this area be blocked by either stickers or objects!
To take advantage of the buzzer, please review the SCOM (Serial/Ethernet Communication) manual located here:
https://www.hattelandtechnology.com/hubfs/pdfget/inb100018-4.htm (reference: “BZZ” - Buzzer Control command,
through the Internal Virtual COM (VCOM) interface).
Light Sensor:
Used to sense level of ambient light in the surrounding environment. The sensor data can be read by suitable software
through the Hatteland Technology SCOM functionality of the unit and thus can be used to control brightness remotely.
Note: This sensor is barely visible to the eye and lies under the glass. It has no illumination behind to indicate it’s
position. Touching or covering this area will naturally make the sensor data inaccurate and should be avoided!
