The FOB battery has a theoretical lifespan of approximately 300 hours of use. Several factors can affect the actual lifespan, so we recommend replacing the battery in the FOB every season (ideally when launching the boat in spring).

If the battery has not been replaced, the FOB will signal low battery before it runs out completely. When the battery is low, the LED in the FOB will flash RED every 3 seconds (in the “ON/OFF” button on the 2-button FOB and in the “DOWN ARROW” key on the 5-button FOB). The battery should then be replaced as soon as possible. Use a good-quality CR2032 battery.

NB! We recommend that you always keep a spare battery (and, for example, a coin to open the battery cover) in the boat.

• Lithium
• 3V
• 20 x 20 x 3.2mm

• • 1. To replace the battery, turn the FOB over and use a coin or similar to open the battery cover.
  • 2. Turn “anticlockwise” to open the cover.
  • 3. Turn past the “OPEN” point to “unscrew” the cover from the FOB itself.
  • 4. Make sure the battery is inserted correctly. The “+” side should point outwards.
  • 5. Screw the cover back into place.
