This is what I've got, don't remember from whom:
"Foursevens Quark Smart QSL-X
Entering programming mode:
- From off, five-click side switch (red led should blink 5 times)
While in programming mode:
- Switching mode tables. Each single-click of the tail switch will go to the next mode table. The number of red blinks after each single-click signifies what table is currently selected. The choices are below.
1: High
2: High, Low
3: High, Strobe
4: Low, Medium, High, Strobe
5: (default) Moon, Low, Medium, High, SOS, Strobe, Beacon high, Beacon Low
- Switching user interfaces. Each double-click of the tail switch will go to the next UI. The number of red blinks after each double-click signifies what UI is currently selected, as follows.
1: Pro
2: Tactical
3: Infinite
Exiting programming mode and saving:
- Single-click side switch (red led will blink once)
Double-click+hold (i.e. hold on third click) while ON in strobe will cycle through different frequencies. IIRC, the slowest is 1Hz. Quad-click while ON in strobe will return the frequency back to default
Ok so in Tactical:
-Double click side from off goes to strobe.
-Press hold side from off cycles through 4 main modes.
-Click on, then quickly double click side cycles through all modes including beacons.
-Click on, then wait, then double click side starts over in moonlight and cycles through all modes including beacons.
-Tail button is momentary in last used mode.
-Click tail button or side button while on to shut off."
Bummer to hear the app has been removed. I wonder if a new one is coming?
