[Zero line
Rejection] When you turn the zero line (transmission line) rejection
on, the line is not shown, which allows you to see fish
echoes near the surface. The width of the line changes
with the transducer used and installation characteristics. If
the width of the line is 1.4 m or more, select [ON]. [ON], [OFF]
[Zero Line Range] Adjust the width of the zero line
Note: DFF3 only, all other transducer models are fixed at
2.0 m
[1.4m] to [2.5m]
[Transducer Draft] Set the distance between the transducer and the draft line
to show the distance from the sea surface. [0.0m] to [99.9m]
[Salt Water] Select [ON] in you use this equipment in salt water. [ON], [OFF]
[Fish Finder
Source] Select the sounder used. [TZTL], [DFF1/
BBDS1], [DFF3],
[DFF1-UHD]
[Transducer Setup] Setup Transducer and Motion Sensor. See "Transducer Setup
menu" on page 3-13.
[Transmission
Power] Set the TX power level.
See the operator’s manual for details.
Note: For DFF1-UHD users, the settings are as follows:
[Off], [Min], [Auto]. The default setting is set to [Auto].
[0] to [10]
[External KP] Select on to synchronize with external sounder’s keying
pulse.
Note: This menu item is not available when [Fish Finder
Source] is set to [TZTL].
[ON], [OFF]
[Bottom Level HF] The default bottom level setting (0) determines that two
strong echoes received in sequence are bottom echoes. If
the depth indication is not stable in the default setting,
adjust the bottom level here. If vertical lines appear from
the bottom echo in the bottom lock display, lower the
bottom level to erase the vertical lines.
If you can not identify the fish near the bottom from the
bottom echo, increase the bottom level. [-40] to [40]
[Bottom Level LF]
[Gain Offset HF] If the gain setting is wrong, or there is a difference in the
gain between the low and high frequencies, you can
balance the gain for the two frequencies here. [-50] to [50]
