## Questions & Answers

**Q: Does it come with the hose connector we see in picture nr1?**
A: If I remember correctly no it doesnt. However I bought one and it was faulty. I returned it and it was signed for yet I was told it didnt arrive. I posted to the address given by them. To get a refund I had to go through my dredit card company as they would not honour.

**Q: If the battery fails, or runs out, does the unit stop with the water shut off?**
A: Hello,
To prevent irrigation failure due to low battery during longer absences, please replace the battery when the battery symbol flashes (the battery symbol flashes when it has max. 4 weeks possible using time). You can find more information on the instruction manual.

Best regards
GARDENA Service

**Q: This product does not fit may gardens tap. I also tried the adapter and it still doesn’t fit. Is there a different tap or adapter I need? I think the**
A: I really don’t understand your question as on checking my own layout, the adaptor that came with the programmer fits my outdoor tap without a problem.  I can only assume that the tap you are using has a nonstandard screw fitting.  I replaced my outdoor tap only a few months ago so perhaps that has to be your way forward.  Thought I could upload you a photo but, unfortunately, I can’t.  however, it is similar to one on Amazon, “Wärmer System Water Bibcock Tap 1/2 inch BSP with Brass Wall Plate Fixture BS1010-2”.  Hope that helps.

**Q: Can I use this with a sprinkler? What do I need if it’s ok?**
A: Yes, it is just a tap that turns on and off at the times and period you set
