Installing The Display And Distributor And Processor Unit; Mounting The Transducer - JRC JLN-550 Instruction Manual

3.1 Installing the Display and Distributor and Processor Unit

Mounting Location
As the signal cable may receive or generate noise, install the unit in a place that is free of
interference.
Do not install the unit near DSB devices, amateur radio or their coaxial cables.
Install it in a place that is more than 1.8 meters from equipment that generates a strong
magnetic field (for example, radar magnetron or speakers) and magnetic compasses.
Install it in a place where it will not be in direct sunlight (expect Wing Display) or hit by
spray from waves or hot air exhaust.

3.2 Mounting the Transducer

Mounting Location
The ultra sound waves that are used to measure ship speed can not make correct
measurements if air bubbles are present effecting the transfer of sound waves. It is
necessary to avoid the source of bubbles and the stream of bubbles when selecting a
position to mount the transducer.
We recommend consulting with the manufacturers of the vessel, as information about the
actual situation for vessels with a similar hull structure is important when selecting a
position to mount the device.
