My DM800HD stab120 using a motor, but it's always hard to find the right position by the satellite. For example: if I want to go to a channel 13 to channel 16 degrees, the engine begins to find it but it does not stop and lose your position by the end wing. But if I am on channel RAI UNO and I want to go to 16 degrees, before I go to a channel or AL JAZZEIRA NOVA (always the same satellite dela RAI UNO - 13 degrees, but of a different provider) and then the tranquility without making a fuss engine after the command is to find any channel I want to 16 degrees. Please tell me if qualquno know what the problem is the entry.
