I went to the Quintum website, but looks like the only solution to your trouble is “take the A200, see how many skips you could get out of it on a nearby lake,and buy a a400 or better”.
There is no mention anywhere on the site in how to insert a pause.
May be an “undocumented” feature, it could be worth giving the guys in Quintum a call.
Many times, they gave me advice for free, on unsuported units.
It helps if you are a technician, and have access to the unit for them.
