USING THE 350TX
MENU FUNCTIONS
After an adjustment is made, the menu disappears and the new sensitivity
setting is in affect. If additional time is needed to study a menu, press and
hold the MENU button and the menu will remain on-screen indefinitely. If
you need to make an additional adjustment, press the UP ARROW or
DOWN ARROW button.
Depth Range. The Depth Range function
controls the vertical distance displayed on the
graphic area of the display. There are nine
depth ranges available. The top of the range
is always 0, or the surface of the water.
Ranges of 0–5, 0–10, 0–20, 0–40, 0–60,
0–80, 0–110, 0–150, and 0–185 metres. Imperial ranges include: 0–15',
0–30', 0–60', 0–120', 0–180', 0–240', 0–360', 0–480', and 0–600'. The
range that positions the bottom depiction closest to the bottom of the screen,
will best utilize the available display resolution.
The 350TX automatically adjusts the depth range depending on the depth of
the water. The unit tries to maintain the
bottom depiction about
²⁄₃ down the total
range (for example, in 6m (20’) of water, the
0-10m (0'-30’) range would be selected).
This provides the best display resolution and
therefore the best target separation possible.
The Depth Range can be adjusted manually.
Press MENU repeatedly until the Depth
Range menu is visible. Two options are
available: Auto and Manual.
The manual setting enables you to adjust the current depth range setting.
The unit no longer adjusts the Depth Range to the most appropriate range
for bottom display. Often, the bottom
may not be visible on-screen. The digital
depth readout always determines the
depth of the bottom, even if it is not
visible on-screen.
