[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 transmis-
sion power by lowering this setting. To disable this fish finder, set this setting to
[Off].
Depending on the connected fish finder, the settings options are as follows:
DFF3: [Off], [1] to [10]
DFF1-UHD: [Auto]*, [Off], [MIN] (Minimum), [MAX] (Maximum)
*: Select [Auto] to automatically adjust the transmission power, which produces
higher quality seabed echoes.
[TX Rate] Changes the rate at which the fish finder transmits a pulse. Adjust this setting to
erase false seabed echoes which may appear between the surface and the actual
seabed.
