Q: What does the flashing antenna symbol and alarm on the Cramer RM1500 mean?

Flashing antenna symbol: boundary wire broken The flashing antenna symbol (blue LED 2) indicates that the boundary wire (grensekabel) is broken, damaged, or disconnected . This is the safety system alerting you that the mower cannot properly locate its working boundaries. Why did this happen? If your mower crossed the boundary wire before the issue appeared, it likely means that the wire was broken during the crossing. The wire can also be damaged by: A clean cut in the cable A wire pulled from one end A disconnection from the charging station (ladestasjonen) How to check and repair Step 1 - Check the charging station: Make sure that both connectors of the boundary wire are firmly plugged in at both ends of the station. Step 2 - Inspect the entire loop of the wire: Walk along the entire boundary cable on your property to identify any breaks, cuts, or damaged areas. The wire should form a continuous and closed loop without interruption. Step 3 - Reconnect or replace: If you find a minor cut, you can repair it with a boundary wire connector. For a complete break or severe damage, you need to replace the boundary wire . Replacement wire kits are available from your dealer. Step 4 - Restart the mower: Once the wire is repaired or replaced and reconnected, restart the mower. The antenna symbol should stop flashing and the alarm will cease. Refer to pages 12-15 of the manual for complete details on installing the boundary wire.

Q: How to reset the Cramer RM2000 robotic mower when the light is solid green but the robot does not start?

When the green light on your Cramer RM2000 robotic mower is solid (continuously lit), it indicates that the mower is in operational mode. It may be charging, parked in the charging station, paused, or ready to mow. If it does not start, follow these steps to reactivate or reset it: Step 1: Check the position of the safety key. Insert the safety key into the slot located under the mower and turn it counterclockwise to the "1" position (Enable). This position activates the mower. If the key is not properly positioned, the mower cannot start. Step 2: Properly activate the START button. Slide the lock of the START button back, then press firmly on the START button. The green light should briefly flash, then remain solid once the mower is operational. If nothing happens, the mower is likely in pause mode and this action will restart it. Step 3: Reset the mower if it does not respond. Press the STOP button to completely stop the mower and remove the safety key. Then open the battery compartment, remove the battery, and wait about 10 to 15 seconds. This operation resets the internal circuits of the mower. Reinsert the battery firmly ensuring it clicks into place, then close the compartment. Step 4: Restart normally. Insert the safety key and turn it to the "1" position, slide the lock of the START button back, then press START. The mower should now start and resume normal operation with the solid green light. If after these actions the light remains solid but the mower still does not start or if you see a flashing red light (error indicator), this signals a more significant technical issue. In this case, refer to the "Troubleshooting" section of the manual to identify the specific error code, or contact your Cramer dealer with your mower's serial number for specialized assistance.

A clean cut in the cable
A wire pulled from one end
A disconnection from the charging station (ladestasjonen)

How to check and repair

Step 1 - Check the charging station:
Make sure that both connectors of the boundary wire are firmly plugged in at both ends of the station.

Step 2 - Inspect the entire loop of the wire:
Walk along the entire boundary cable on your property to identify any breaks, cuts, or damaged areas. The wire should form a continuous and closed loop without interruption.

Question 10

What does the flashing blue light on the charging station of the Cramer RM2000 robotic mower mean and how can I resolve this issue?

Accepted Answer

The flashing blue light on your Cramer RM2000 robotic mower's charging station indicates a specific problem: the boundary wire is broken, disconnected, or detached. This wire defines the working area of the robot and is essential for its operation. The robot cannot function properly until this issue is resolved.

Start by checking the most common connection points. Inspect the cable connectors at the back of the charging station and ensure they are securely plugged in. Also, check that the boundary wire has not been accidentally disconnected at the entry points of the station. If the connections seem fine, follow the boundary wire all around your garden to look for visible damage: cut wire, pulled by a root, damaged by gardening tools, or deteriorated by repeated passage of the mower.

If you find a visible break or damaged area, repairing it requires a specific connection kit for robotic mowers. The kit should contain wire connectors, cable stakes, and a replacement segment of boundary wire. Cut about 60 centimeters from each side of the damaged area to remove any degraded section, then insert both ends of the wire into a connector designed for this purpose and secure it tightly with the stakes.

If you do not identify a visible break, the problem may be a micro-crack, oxidation of the connectors, or a partial disconnection. Unplug the charging station from the electrical outlet, wait 10 seconds, then plug it back in. Check if the light remains flashing blue or changes color. If the light turns solid green, the problem was a simple temporary disconnection. If the light remains blue, clean the connectors with a dry cloth and reinsert them firmly.

For a systematic search for an invisible break, you can use the cable splitting method: disconnect the boundary wire halfway along its path and test each half independently by reconnecting one part. The flashing blue light will indicate which side the break is on, allowing you to focus your search. Another option is to use a portable AM radio: an intact cable creates interference with the radio signal, allowing you to trace the interruption to the break point.

After a repair, reconnect the station, wait for the light to turn solid green, then test the robot by placing it on the charging station. If the light remains flashing blue after checking the connections and repairs, it may indicate an electronic failure of the station itself. In this case, contact Cramer's customer service for technical assistance or a warranty replacement.
