9. INSTALLATION

Grounding

The display unit contains a CPU. While it is operating, it radiates noise, which can interfere with radio equipment. Ground the unit as follows to prevent interference:

The ground wire for the display unit should be 1.25sq or larger and as short as possible.

The signal ground and frame ground are separated, however the power line is not isolated. Therefore, do not connect the signal ground to the frame ground when connecting other equipment to a positive ground battery.

External equipment

The power supply port is commonly used for connection of external equipment such as a radar. Refer to the interconnection diagram on page S-1 or S-2 for connection of external equipment.
