switch is changed. Only if the transducer is faulty do you need to manually identify the
transducer in the menu.
The 300TX can work with an older dual beam transducer (model DHS-W only); however
the fishfinder will not show left/right fish location. If this transducer is being used, leave
the menu set to “tri-beam”.
When using a dual beam and tri-beam transducer together with a switch, leave the
menu set to Tri-beam. When using a dual beam and Wide Side transducer together
with a switch, manually select the correct transducer in the menu each time the switch is
changed.
Bottom Black.
There are two selections available: Off and On.
The factory setting is Off. With this setting, the 300TX displays
the bottom using Structure ID. This allows you to determine the
texture and relative hardness of the bottom. Selecting Bottom
Black “ON” causes the unit to blacken in the display below the
bottom. This gives the user easiest recognition of the bottom
location, even from a great distance.
The 300TX remembers the Bottom Black setting when powered
off.
Diagnostic.
Two options are available” Hide and Show. The factory setting is Hide.
Selecting Show brings up the Diagnostic screen. See the Using Diagnostic section for
more information.
Reset.
With the many User Options available to customize the 300TX, it is easy to
configure the unit in such a way that it is detrimental to a particular use. By using the
Reset function, all variable or user-controlled features of the 300TX are returned to the
factory settings.
The reset function is an important first step in troubleshooting problems to ensure that a
user selected setting is not the cause for the perceived problem.
Using the Diagnostic Feature
The 300TX contains a powerful diagnostic tool that can aid in determining the cause of
a problem.
