[RX Band]
The RX band width is automatically set according to the TX pulse
length. To reduce noise, use [Narrow]. For increased resolution,
use [Wide]. To set the RX band width manually, select [Manual].
[RX Band Width]
Sets the RX band width manually, when [RX Band] is set to [Man-
ual].
[TX Cycle]
Sets how often to transmit pulses. Valid when [TX Cycle Select] in
the [TX/RX] menu is set to [Manual]. Adjust the TX cycle setting
when low-level interference appears on the display.
[
Deep Mode
] (The items other than [TX Cycle] are valid when [Deep Mode] in the [TX/
RX] menu is set to [Auto].)
[TX Power]
When using more than one fish finder with the same frequency, in
close proximity, interference can occur. To reduce the interference,
you can reduce the transmission power by lowering this setting. To
disable this fish finder, set this setting to [Off]. To display the sea-
bed as best as possible, set the power level to [Auto].
[TX Freq]
Sets the TX frequency. Shift the frequency slightly when interfer-
ence from other sonars or fish finders occur.
[TX Pulse]
Set the transmission pulse width (setting range: 0.3 to 26.0 * msec).
The smaller the value, the higher the detection resolution, but the
shorter the detection distance. On the other hand, increasing the
value lowers the detection resolution, but increases the detection
distance.
* When [Simul. TX] in the [TX/RX] menu is set to [Auto] or [On], the
maximum TX pulse length is 5.0.
[Envelope Edge
Width]
Suppresses interference to acoustic equipment such as fish finders
and scanning sonars, etc. (your own and others).
[RX Band]
The RX band width is automatically set according to the TX pulse
length. To reduce noise, use [Narrow]. For increased resolution,
use [Wide]. To set the RX band width manually, select [Manual].
[RX Band Width]
Sets the RX band width manually, when [RX Band] is set to [Man-
ual].
[TX Cycle]
Sets how often to transmit pulses. Valid when [TX Cycle Select] in
the [TX/RX] menu is set to [Manual]. Adjust the TX cycle setting
when low-level interference appears on the display.
[
Beam Direction
]
[Tilt]
Sets the tilt angle.
[Bearing]
Sets the bearing.
