ENGLISH
1. In order to guarantee optimum signals, it is necessary to ensure that the transmitter
Moduson®3's mass and the Foxy console's mass are connected.
2. The transmitter telemeter has a self-resetting fuse, in case the connection creates
a short circuit, the device puts itself in safety and does not produce any signal. In
this case, turn the device's power off, eliminate the short-circuit, wait a few seconds
and switch it back on.
3. Adjusting the gain to overcome a distorted signal in the air.
