Each button on the transmitter corresponds to a specific crane function (e.g., Up, Down, Left, Right, Forward, Backward, Stop). The exact mapping of buttons to functions may vary depending on the crane system and receiver configuration. Always refer to the crane's operational manual for specific button assignments.
- Press and Hold: For continuous movement, press and hold the desired function button.
- Release: Releasing the button will stop the corresponding movement.
- Emergency Stop: Locate and familiarize yourself with the emergency stop button on both the transmitter and the crane system. Use it immediately in case of an emergency.
5.2 Operational Range
Maintain a clear line of sight between the transmitter and receiver whenever possible. The effective operating distance is typically up to 100 meters, but environmental factors and obstacles can reduce this range. Do not operate the crane if signal integrity is compromised.
