Programming Instructions:
To switch mode groups: Turn on light for 2s then rapidly tap the switch 8 times, the light will then enter the programming mode and begin to flash. With the light in programming mode, tap the switch the same number of times as your desired mode group. The light will blink and your mode group will be memorized.

Example: To select mode group 3, tap the switch 8 times quickly to enter programming mode. As soon as the light enters programming mode and starts flashing, tap the switch three times (for group 3). The light will blink to recognize the mode group change.

"Turbo" Timer
A) 5 Minutes (Default)
B) Self Set Turbo Timer: Turn light on for 2s then rapidly tap the switch 8 times, the light will then enter the programming mode and begin to flash. With the light in programming mode, tap the switch 30 times to enter the turbo timer set mode. The light will then switch to 100% power. When the light is at the desired temperature for the turbo step down, turn the light off. The turbo timer will then be set. Maximum of 20 minutes. Setting a turbo timer below 4s disables it. It applies to all modes above 50% and smoothly ramps them down to 50%.

Low Voltage Protection
The firmware has low voltage protection, if the voltage drops below 3V, the brightness is reduced. That brings the voltage up again a bit, but if the voltage of the drained battery falls below that again, brightness is reduced again - and so on, down to a very low level. Low voltage step-down can be disabled by me if desire.

Battery Voltage Check
The blinking signal after 8 fast taps is actually a battery monitor, the number of blinks relates to battery voltage: One blink for each 0.1V above 3.0V, so 12 blinks is full, 3-4 blinks is quite empty.

*Mode Group are memorized even through battery changes
*It's almost impossible to accidentally change mode groups
*DriverVN Can take 1 li-ion cell for XPG2 or XML2 (~2.5-4.2V)
*DriverVN Can take 2 li-ion cell for XHP50, XHP70, MKR (~5V-8.4V)
*No memory = always resets to 1st mode after 1 second of being off.
*Memory = Always memorize last mode after 1 second of being off.

User Interface:


To Set a Mode Group

Configure the turbo timer
Enter config menu by 8 (or more) fast taps, wait for the blinking signal, then enter turbo config mode by the 20 taps. The light then runs at full power. Let it run for the desired time (e.g. until it gets hot; use a full battery), then tap to switch off. That time is now set for the turbo timer. Setting a time below 4 seconds disables it. The turbo timer has a maximum of ~20 minutes (this is also the default). It applies to all modes above 50% and smoothly ramps them down to 50%.

Low voltage protection:
Whenever the battery falls below 3V under load, brightness is reduced (about half). The reduced load usually brings up the voltage a bit. When it drops below 3V again, brightness is halved again - and so on, down to a very low level. It will not switch off and leave you in complete darkness though.

Config Mode
8 Quick Click enters Config Mode. Light will blink ON & OFF if activated or does nothing if Config Lock.
Each setting has 4 group of Clicks
Example: 8-1-3-2 = 8 Click, then 1 Click, then 3 Click, then 2 Click
Note* Brief pause between Clicks for successful indication blinks before proceed. 
Note* All configurations memorized even after battery changes.
Ramp or Discrete UI Toggle
8-1-1-1 = Ramp 
8-1-1-2 = Discrete
Ramp UI:
Quick Click turns ON or OFF
From OFF: Click&Hold ramps up from lowest level
From ON: Click&Hold alternates ramps up or down
Note* Double Blink at top of ramp indicates Maximum 70% reached. Double Click activate 100% Turbo. Last mode memorized.
Ramping & Discrete UI Hidden Features
Double Click = 100% Turbo
Triple Click = Strobe
Four Click = Beacon (Roadside Caution Signaling OK)
Five Click = Voltage Blinks
Note* Hidden Features can be activated from ON or OFF
Note* While in Hidden Features Quick Click revert back to last mode used
Note* Strobe is visually a bright constant ON with fast blinks achieved with specific blink frequency & duty cycle. 
Note* Beacon is a dim constant ON with slow double blinks. Good for beacon locator & roadside caution alert .
Discrete UI A (8-1-3-1)
From OFF: Quick Click turns ON
From ON: Quick Click advance sequence
From ON: Click&Hold reverse sequence
If light stays ON for >5s, Quick click turns OFF
Note* No fast way to turn off light before 5s. Great in practice but least tactical. Last mode memorized. 
Discrete UI B (8-1-3-2)
Quick Click turns ON or OFF
Click&Hold advance sequence
Note* Similar to VNX2 UI. Last mode memorized. 
Discrete UI C (8-1-3-3)
Quick Click turns ON & advance sequence
Click&Hold turns ON or OFF
Note* Last mode memorized so no access Lowest/1st level from OFF.
