Changing the radio channel

 

Should malfunctions occur (connection is cut off or signal quality declines):

“Scanning for free radio channel...” message

 

*   Either:

Press the direct access button “Freq. change” (arrow with hash key).

Or:

Open the main menu with the MENU button,

open the menu “Crane operation”,

open the menu item “Freq. change”.

●   The transmitter disconnects the connection to the receiver.

●   The receiver is waiting for the corresponding transmitter.

●   The message “Scanning for free radio channel...” appears on the display.

●   For wireless technology XR2: The transmitter scans the 433 MHz frequency range and evaluates the current radio situation in its surroundings. Based on this, the transmitter selects the most optimal radio channel for the connection.

●   Only for wireless technology XR0: The transmitter automatically searches for a new free radio channel, and occupies it.

●   The receiver finds the transmitter.

 

 

 

Release signal

●   The display shows “Release”.

*   Press the HORN button and let it go.

●   The sound of the horn can be heard at the transmitter and at the crane.

●   The crane is ready for use.

 

The radio channel can only be changed when the transmitter has not been set to a fixed radio channel. To set the transmitter to a fixed radio channel: See Setting the radio channel.

 

 

Only with wireless technology XR2

In the case of a channel change, the transmitter evaluates the current radio situation in its surroundings. If the radio situation changes during running operation, the radio channel is not automatically changed.

Should malfunctions occur (e.g. connection is cut off or signal quality declines), the channel should be changed on the transmitter. The radio situation in the vicinity of the transmitter is then re-evaluated.

 

If a channel change is made multiple times in brief succession:

●   The radio situation is re-evaluated each time and the radio channel is changed as previously described.

●   If the radio situation has not changed since the last channel change, (e.g. because the transmitter is at the same position):
The transmitter will still change the radio channel.

Also if the evaluation of the local radio situation gives the same result as with the last channel change, the radio channel that is used is still changed. In this case, the next best radio channel is used.

In this way you can switch between the five best radio channels.
