Service
When using more than one fish finder with the same frequency, in
close proximity, interference can occur. To reduce the interference,
you can reduce the transmission power by lowering this setting. To
disable this fish finder, set this setting to [Off]. To display the sea-
bed as best as possible, set the power level to [Auto].
Changes the rate at which the fish finder transmits a pulse. Adjust
this setting to erase false seabed echoes which may appear be-
tween the surface and the actual seabed.
Show/hide the seabed. Set this to [Off] to in the following circum-
stances.
• The seabed is not visible on-screen with the current range set-
ting. For example, the seabed is at 200 m, the on-screen range
is set to 100 m.
• When fish schools are mistaken for the seabed, resulting in un-
reliable depth and echo readings.
When set to [Off], the on-screen depth is displayed as "-.-".
