Operations
This light has 3 main levels (High, Medium, and Low) and a beacon-strobe mode. Each main level can be programmed to one of its two sub-levels, and the second sub-level of each main level can be further programmed to different brightness levels.

Basic Operation
1 click — Turns the light on to High, or turns it off.
2 clicks — Turns the light on to Medium.
3 clicks — Enters beacon/strobe mode.
Press and hold (0.6s+) — Turns the light on to Low, then cycles through Medium and High. Release at the desired level.

Advanced Operation & Configuration
Press and hold to cycle from Low → Medium → High. The cycle always starts from Low regardless of your current level. Release at the desired level.
Double-click at any main level to toggle between its two sub-levels (H1/H2, M1/M2, L1/L2). Sub-level selections are memorized through power cycles and battery changes.
To program the second sub-level (H2, M2, or L2) to a different brightness: double-click 6 times at that main level to enter configuration. Each subsequent double-click cycles through available brightness levels. Single click to save and exit. Settings are memorized through power cycles and battery changes.
Battery Indicator — From off, 4 quick clicks. The main LED flashes 1–4 times to indicate remaining battery capacity.
Beacon/Strobe — 3 clicks from off to enter. Double-click to cycle through beacon and strobe options. Settings are memorized through power cycles and battery changes.

Mode Groups
This light has three mode groups: G5 (factory default), G6, and G7. From off, select with 5 clicks (G5), 6 clicks (G6), or 7 clicks (G7). Selections are memorized through power cycles and battery changes.

All mode groups share the same basic controls:
H can be either H1 or H2 | M can be either M1 or M2 | L can be either L1 or L2
From off: 1 click → H | 2 clicks → M | Press and hold → cycles L, M, H

G5 — H1, M1, and L1 are fixed. H2, M2, and L2 are programmable.

G6 & G7 — All six levels (H1, H2, M1, M2, L1, L2) are fully programmable across 12 available brightness levels. Double-click 6 times at any level to enter programming mode. Double-click to go up one level, triple-click to go down. Single click to exit.

Factory Reset — Three consecutive 5-clicks (or 6-clicks, 7-clicks) from off resets G5 (or G6, G7) to factory defaults.
