Selector Switch
The Echo-Box1 can work with depth trans-
ducers of various frequencies within the range
of 140 kHz to 160 kHz. Switch position # 8 is
the lowest frequency, # 7 is the next higher
one, and so on, and # 9 is the highest fre-
quency.
In case the depth transducer is replaced,
the new number must be selected on the
switch. It can be read from a tag on the cable
on all Tecnautic-supplied sensors.
An unknown sensor frequency can be
found by selecting a switch position with which
the echo sounder would work satisfactory at
higher depth values.

Speaker Installation
Echobox-1
The speaker should be placed into a cabi-
net in such a way, that the speaker is sealed
from the rear side. This is important for good
sound quality. Without such a sealed cabinet,
the sound will be distorted and rather weak.
