How do I fix the attachment loop?

Included in the scope of delivery of each LEUCHTIE is a fixation loop, which serves as loss protection.

In order to secure the LEUCHTIE to a collar/ harness with the enclosed fixation loop, pull the open end of the tube through both transparent rubber rings of the loop.

Assemble the connecting loop


How do I activate my LEUCHTIE Mini?

Activation of the luminous collar LEUCHTIE MiniTo prevent your LEUCHTIE Mini from switching on during shipping, one of the batteries has been inserted upside down as a transport lock. For the first activation this battery must be turned around:

  • To open the LEUCHTIE, separate the tube at the side of the size sticker from the battery pack with a slight twisting movement, taking care not to use excessive force.
  • Remove the battery from the end of the tube and turn it around.
  • Place the battery into the light tube with the negative pole ahead.
  • Push the battery pack back into the end of the tube. Take care that the spring is centred in the battery pack.
  • Press tube and battery pack firmly together as far as it can go. There must be no gap between the battery pack and the tube.

How do I activate my LEUCHTIE Plus / Premium / Premium Easy Charge / Pro Easy Charge?

My LEUCHTIE doesn't switch on

Possible causes may be:

The LEUCHTIE was not activated for the first use: We have compiled information on how to activate the LEUCHTIE Mini as well as the Plus, Premium, Premium Easy Charge and Pro Easy Charge models.

The energy is used up: Please insert two new batteries for the battery-powered models Mini, Plus and Premium or recharge the Premium Easy Charge and Pro Easy Charge immediately.

the batteries were inserted the wrong way round when changing the batteries: Information on the battery change for both Alkaline batteries and rechargeable batteries is linked.

the battery pack has been placed the wrong way round on the tube: Please check this with the linked information on changing the batteries.

The LEUCHTIE is not closed correctly: Press the battery pack and the tube firmly together on both sides as far as it will go - there must be no gap between the battery part and the tube.

The contact springs are defective: The springs protruding from the ends of the tube on both sides are either not straight or not tightly screwed into the nut.

The batteries have leaked: If you notice battery acid in the battery part or discoloration on the plastic sockets at the ends of the tube, on wires or on the cable inside the light tube, please send us your LEUCHTIE for repair.

If you cannot solve the problem, you are welcome to send your LEUCHTIE to us for inspection and repair with the completed service form.


My LEUCHTIE flashes

A rhythmic flashing on the Premium and Premium Easy Charge models (version up to 2020) indicates that the energy is used up. Please change the batteries of your LEUCHTIE Premium or recharge your Premium Easy Charge immediately.

If your LEUCHTIE flashes arrhythmically, there is probably a loose contact.

My LEUCHTIE has a loose contact

If your LEUCHTIE has a loose contact please check whether:

  • the LEUCHTIE is firmly connected on both sides: the battery pack and the tube must be fully pushed together so that no gap is visible between the battery pack and the tube.
  • both springs, which protrude from the tube, are straight and tightly screwed into the nut and show no discoloration.
  • the edges of the battery compartment are not kinked and therefore the tube cannot be pushed on as far as it will go.
  • the silicone sleeves are located centrally over the transition from the tube to the battery pack (the end of the silicone sleeves with the ring bead is located on the battery part).
  • the silicone sleeves fit tightly and have no defects.
  • the inside of the silicone sleeves and the ends of the tube over which the sleeves sit are clean, dry and especially free of grease. Because of the sebum deposits of the dog's coat, we recommend cleaning the sleeves with warm water and washing-up liquid if necessary (rinse well and allow to dry completely). Please do not use any aggressive or solvent-based cleaning agents.
  • the LEUCHTIE is attached to the collar / harness and tension on the fixation loop, especially when the dog lowers its head, causes a short loss of contact or even the opening of the LEUCHTIE.

If necessary, a little contact spray on the springs / battery poles can also help.
