Video Level Setting - JRC JMA-7710-6 Instruction Manual

5.9.2 Video Level Setting

Do not change the set point carelessly.
Attention
The video level is for deciding the minimum input signal level for the ATA's target detection circuit.
The video level can be set to the range from 1 to 63.
Unless the level is set to a proper value, the acquiring and tracking functions of ATA will be degraded.
Setting the video TD level
The video TD level is the signal level of target acquisition in the guard zone. As the setting value is smaller,
a weaker echo is acquired.
If the setting is too small, the echo is acquired even due to the sea clutter returns. In that case, increase the
setting value.
