FAQ (frequently asked question)
1) Please power on the SonarBox first, then power on the
display. If power on in wrong sequence, please restart the
display again.
2) Please make sure the radio environment is in good condition.
Too close to the WIFI, BLUETOOTH device, or noisy R/C controller
may result a very short R/C distance.
3) Please make sure the autopilot-box is powered by the
remote receiver (DC5V).

1) keywords: ANTENNA INSTALLATION
Please confirm that the 2 antennas are connected properly and
perpendicular to the water surface (except for directional
antennas). The distance between TF7xx antenna and remote
-control receiver antenna should be as far away as possible
on the boat (at least 15cm).
Please ensure that the antenna on board (boat) is as high
as possible (at least 15cm above the water surface), and the
antenna of display is at least 1.5 meters high above the ground.
2) keywords: REMOTE-CONTROL INTERFERENCE
Please ensure that there is no strong wireless interference
nearby, such as high power 2.4G remote-control. Please turn
off the remote control when operate TF740 / 750. TF740 /
750 can complete various operations without a remote
control.
When the distance is more than 150 ~ 200 meters, a 2.4G
remote control will interfere the high-speed communication
of the sonar when being used in 1.5m range, which cause
the display image appearing mosaic-like. For longer range,
please keep the remote control more than 1.5m away from
the screen.
3) keywords: ANTENNA / CABLE BROKEN
Whether the antenna is damaged (the antenna interface is
SMA internal thread internal pin, the middle pin is easy to
break internally due to external force).
