Receiver unit
The case of the receiver unit is durable and anti-vandal. The level of
tightness complies with IP 67. Elastic inserts around the perimeter of the case
protect the electronic component of the sonar against shock, vibration and
rough handling (including at low temperatures).
Transducer and battery compartment
Transducer design is frost-resistant and airtight (IP 68). The sensor is
screwed clockwise into the battery compartment. The silicone ring on the
sensor is used to seal the joint between the sensor and the battery
compartment. For reliable sealing, the sensor must be tightened with force.
When installing an AA battery, the polarity must be observed (see the figure
on the left).
IMPORTANT!
It is advisable to install the battery at home in a warm place. This will
prevent condensation in the battery compartment. Be careful when
replacing battery near a water reservoir. Protect the sensor from shock and
drowning.
