Normally, “On” should be selected. To stop transmission, select “Off”. When
turning the power off and on again, “On” is selected automatically.
TRANSMISSION POWER
Sets transmission power to High or Low.
Normally, select “High”. When the gain becomes too high in shallow waters,
select “Low”.
TRANSDUCER
Selects the transducer to use, 600 W or 1 kW.
CAUTION
Select the transducer properly.
If not, the transducer may be damaged.
TVG (50 KHz, 200 kHz)
TVG (Time Varied Gain) compensates for propagation attenuation of the
ultrasonic waves. It does this by equalizing echo presentation so that fish
schools of the same size appear in the same density in both shallow and deep
waters. In addition, it reduces surface noise. Note that if the TVG level is set too
high short range echoes may not be displayed.
