CTEK Multi XS 3600 Charger

SBos

Hi All

Having returned to caravanning after an 8 year break I have found the above charger that I used on my leisure battery and it still works. However I cant find the instructions.

It has a picture of a motorbike, a car and what appears to be a snowflake. Can anyone tell me what the snowflake mode is?

Also does it automatically know when to trickle charge?

Thanks.
