Important
The EK80 is an advanced product. It is used with other advanced products. There is important information that you need to know.
Before you turn on the EK80 system
Before you turn on the EK80 system, make sure that the transducer is submerged in water. If you are using a drop keel, make sure that you have sufficient water depth to lower it.
Caution
You must never set the EK80 system to "ping" unless the transducer is submerged in water. Most transducers are damaged beyond repair if they transmit in open air. Prevent inadvertent use of the EK80 system whenever a transducer is not submerged.
When the EK80 system is not used
When you do not use the EK80 system, turn off the display and the Processor Unit. If you are not using the EK80 system for a long period of time, we recommend that you turn off the transceiver(s).
When you are docking your vessel
You must never turn on the EK80 system when the ship is in dry dock. The transducer(s) may be damaged if the EK80 system transmits in open air. To prevent inadvertent use of the EK80 system, pull out the mains plug on the Processor Unit whenever your vessel is in dry dock. Additional precautionary measurers should be considered.
If something breaks down
If you believe that something has broken down, contact your local dealer. A list of all our dealers is provided on our website.
If you are unable to contact a dealer, observe the support information in this publication.
When you want to turn off the EK80 system
You must never turn off the EK80 system by means of the on/off switch on the Processor Unit. You must ALWAYS select Exit on the top bar.
Note
If you turn off the EK80 system by means of the on/off switch on the Processor Unit you can damage the software and the interface settings used to communicate with external devices.
