5. Getting Started
5.1. Turning the unit on and off
The IS20 offers two options for powering the device: through the N2K connector or the power cable
connected to the Power and NMEA 0183 input/output connector. Once power is supplied, press and
hold the POWER button for 3 seconds to turn on the screen. The Quark-elec logo will be displayed,
followed by a legal notice page upon completion of the initialization process. To proceed, simply tap
'Accept', and the default page will be presented.
To power off the IS20, press and hold the POWER button for 5 seconds while the display is active.
5.2. Adjust the brightness
When the IS20's screen is active, pressing and holding the central area of the screen will bring up the
brightness setting page. From this page, you can conveniently adjust the screen brightness to your
desired level, ensuring optimal visibility in different lighting conditions.
5.3. Setup
To access the setup page on the IS20, simply double tap the POWER button while the screen is turned
on.
During the initial setup process, the most essential parameter to configure is the Data Source. The IS20
offers four different data source options: NMEA 2000, NMEA 0183 4.8K, NMEA 0183 38.4K, and WiFi.
From the drop-down list, select the appropriate data source that best suits your requirements. Once
selected, the system will automatically save the chosen data source. Press the ENTER button to
confirm, and the screen will return to the display page. If there is valid data input from the selected input
port, it will be promptly displayed on the screen.
