Sentry 300 Gate Opener Manuals
Please
choose the appropriate manual for your gate opener. This is determined
by the part number of the control board located near the top where it
reads “USAutomatic”. This is important as each control board revision
has different features and we want to be sure you match the correct
manual with your control board revision.
