THE GUARDIAN HT3 v2 BLUE LIGHT REMOTE HAS BEEN DISCONTINUED
This remote is still available for purchase as a BOSS HT4 2211L Remote but due to a merge between Boss and Steel-Line the compatibility of the genuine remote has been altered.
During an upgrade to a newer model version of the 2211L remote (Model: 303RTX) the Rollerdoor code has not been included.
