When performing normal work with the radio remote control:

●   The bar at the right-hand edge of the display shows the battery capacity remaining.

Four full bars indicate a full battery; four empty bars indicate an empty battery.

Once the preset remaining battery time reaches the alarm threshold:

●   The message “Battery very low” appears on the display.

The remaining battery time at which the message should appear can be set. See Displaying the remaining battery time and setting the alarm.

●   No new command for crane travel, trolley travel or lifting/lowering can be issued until the message has been confirmed.

    Press ENTER.

    Set down the load.

    Change the batteries.
