Diagnostic can be used to evaluate the health of the batter by showing the current voltage.
Total Time. The total time category indicates the total time the unit has been in use since shipped from the factory. It is normal for some hours to appear in the total time when the unit is new due to factory testing. While this is often of interest to the user, it is primarily a diagnostic tool for the repair technician should the unit need service.
Using Alternative Transducer
Wide Side Operation
The Wide Side Transducer is a specialized “side-looking” transducer that is extremely useful for bank fishing or looking for bait fish in open water. The Wide Side transducer uses three different sonar elements that transmit signals to the left, right and straight down from your boat. The downward beam is 200 KHz with a 24-degree area of coverage. This beam maintains a continuous digital depth readout from the bottom directly beneath your boat. The side beams are 455 KHz with a 16-degree area of coverage. The side-looking element can be used independently, or together to locate targets near the surface of the water on either side of your boat.
The Wide Side transducer can be connected directly to the 300TX or used in conjunction with the standard transducer through a transducer switch. When used with a switch in conjunction with the Tri-Beam transducer, the 300TX recognizes which transducer is connected whenever the switch position is changed.
When a Wide Side transducer is connected, the screen display changes to display the information from the side-looking elements. The Wide-Side transducer has four views available: Left, Right, Down, and Both. These views are controlled by the View Menu, which is only present when operating in Wide Side mode. The default view is both, in which information from both the left and right elements are display in screen. The digital depth of the water beneath you r boat is always present.
Viewing both left and right sides simultaneously gives you an excellent tool when searching for bait fish in open water, or
when following a creek bed. However, you will have a greater display resolution if you view only one side.
The down view is similar to the traditional view using the standard transducer, however there is no Tri-Beam information available, such as fish location.
When operating in Wide Side mode, the range must be adjusted manually, since the bottom is often not visible on-screen. Ranges of 15’ (5m), 30’ (10m), 60’ (20m) and 120’ (40,) are available. Also, Zoom is not possible in Wide Side mode, and the Zoom menu is not available.
