How the Dual Flush operation for this siphon works.

The full flush volume is achieved by flushing the WC in the normal fashion of fully depressing the lever and immediately releasing once the flush has started. The short flush volume is achieved by fully depressing the handle in the normal fashion and holding the handle in the down position until the flushing cycle has finished
