guaranteed. Therefore, any position data
should be verified against other sources to
confirm reliability.

BOTTOM LEVEL: If the depth indication is
unstable in automatic operation, or the
bottom echo cannot be displayed in the
darkest gray tone by adjusting the gain
controls in manual operation, you may
adjust the bottom echo level detection
circuit, for both 50 kHz and 200 kHz, to
stabilize the indication. Generally, lower the
bottom level for inner hull installation where
the receive level is too low. If the bottom
level is too low it may be difficult to
discriminate fish from the bottom, resulting
in unstable depth indication. And if the
bottom level is too high the depth indication
may not appear.
1. At the installation menu, press ▼ to
choose SET BOTTOM LEVEL and then
press ►. Several seconds later the
following display appears.
Bottom level
