How do you activate the timer function in the 4PLS transmitter?

In practice, I want to time myself for 5 minutes (alarm at the end) using my Futaba 4PLS transmitter.

Cannot figure it out. Pls Help.

First, assign SW1 to the timer function (pages 66-67 of the manual) then setup the timer how you want it to work (pg 94 of the manual) and from there, each time you push the SW1, it will start the timer.

got it... thanks.
