VTBox200 is powered by authentic DNA 200 chip by EVOLV. DNA 200 is a power regulated DC-DC converter with digital switch-mode for personal vaporizers. It features Evolv’ s patented wattage control, temperature Protection, preheat, OLED screen, and waterproof onboard buttons. The DNA 200 runs from 3 cell lithium polymer battery, and features cell-by-cell battery monitoring and integrated 1A balance charger. It is the most advanced personal vaporizer.

Modes:

Locked mode: Pressing the fire button five times with less than 0.7 seconds it will cause the device enter lock mode. In locked mode, the device will not fire and the output power will not adjust accidentally. While in locked mode, the screen will be off, except that pressing a button will show  “Locked, Click 5 X”. To Exit locked mode, press the fire button 5 times.

Stealth mode: While locked, holding the fire and down buttons simultaneously for 5 seconds, it will switch to stealth mode. In this mode the display is off, it will still show error and lock messages. To switch back to normal display mode, hold down the fire and down buttons simultaneously for 5 seconds. This setting is stored to internal flash memory, and remains if power is removed.

Power Lock mode: Holding down both the up and down buttons for 2 seconds, it will place the device in Power Locked mode. In this mode, the mod operate normally, but you are not able to change the power setting. This mode prevents accidental power level from being changed due to the buttons being pressed while in a pocket. To Exit power locked mode, hold the up and down buttons for 2 seconds.

Resistance lock: The DNA 200 relies on the cold resistance of the atomizer to measure temperature accurately. If the connection is not stable or if you find the measured resistance drifts with time, it may be desirable to lock atomizer resistance. To do so, while locked hold both the fire and up buttons for 2 seconds to enter resistance lock mode. In this mode, the DNA 200 will use the present atomizer cold resistance without refinement until the atomizer is disconnected or the resistance lock is disabled. A lock symbol will replace the ohm symbol on the display. To disable resistance lock, repeat the procedure to lock it.

Max temperature Adjust mode: From lock mode, holding down both the up and down buttons for 2 seconds, it will place the device in Max Temperature Adjust mode. Once this mode is entered, the max temperature will be displayed. The up and down buttons are used adjust the max temperature. To save the new temperature setting and exit, press the fire button.
