1.4 Raising/Lowering the Transducer
1.4.1 Lowering the transducer
With the boat at the fishing ground and the power on, press the key to lower the
transducer. The lamp to the left of the key flashes during lowering and the message
"Lowering " appears at the bottom of the screen. When the transducer reaches the
water, the message "TX Start" appears and transmission begins automatically. After
the transducer is fully lowered the lamp the left of the key lights steadily. You can see
the position of the transducer by watching the transducer mark at the top left corner
on the screen. See section 1.4.3.
In normal use, fully lower the transducer. The time required to fully lower the transduc-
er is indicated in the following table.
If the transducer becomes entangled in the net for some reason, partially raise the
transducer with the key. The function of the key depends the menu setting (main

[Fixed Position] : The transducer stops at the selected position. If the key is oper-
ated while the transducer is being raised or lowered, the transducer stops at the fixed
position. The fixed position can be set by clicking the transducer position marker. See
the next page.
[Any Position] : The transducer starts lowering when the key is operated. The low-
ering is stopped when the key is operated. To raise or lower the transducer from the
current position, use the or key. The key does not control lowering or raising
of the transducer.
You can see the approximate position of the transducer with the transducer position
marker (see section 1.4.3). When the transducer is stopped before it reaches full pro-
trusion, the lamp to the left of the key lights steadily.
