ETR TX/RX dialog box
Click TX/RX on the System menu to show this dialog box.
Gain adjustment: Compensate for too high or too low gain and adjust gain balance of low
and high frequency. Setting range: -50 to 50.
Freq adjustment: Fine tune the Tx frequency when interference cannot be rejected
otherwise. Setting range: -10.0 to 10.0.
TX power reduction: This setting is normally "OFF". However, if an echo sounder of the
same frequency as your own is being operated nearby, interference may appear on your
display. In this case, both parties should lower their TX power to remove the interference.
Turn this item ON to lower TX power.
Tx pulse length: Pulse length is automatically selected according to display range and
display shift settings. For manual selection, choose a short pulse when resolution is
important and choose a long pulse when long-range detection is your objective. To improve
resolution on zoom displays, choose the pulse length setting Short1, Short 2 or Manual.
Short1: Detection resolution is improved, however detection range is shorter (1/4 of
standard) compared to Short2.
Short2: Detection resolution is improved, however detection range is shorter (1/2 of
standard).
Standard: Use for general fishing operations.
Long: Detection resolution is lower, however detection range is longer (2x normal).
Depending on the range, the Tx rate is 1/2 of the normal.
Manual: Operator chooses pulse length.
