Operation
Basic operation of the DNA 75 is as follows. To wake the device from power off state, tap the
Fire button. To generate vapor, press the Fire button. To change the wattage setting for more or less
vapor, click or hold the Up and Down buttons.
Display
The DNA 75 has a small .91” diagonal white OLED screen. The screen is attached to the main
board by a flexible cable, allowing freedom in the design of your device. The screen’s default position is
on top of the board, between the fire and adjust buttons. This allows for easy assembly. The screen
connects to the board with a ZIF connector, so alternate placement is possible. It is also possible to
order screens with custom length and shape flexible cables, allowing screen placement anywhere in the
device. Please use caution when handling the screen and design the device so that the cable will be
secured or strain relieved in operation.
Watt setting: The power level currently set on the DNA 75.
Battery indicator: The current state of charge of the battery.
Temperature display: When not firing, the maximum heating coil temperature setting. While firing, the
actual temperature of the heating coil is displayed.
Volts display: The output voltage being supplied to the atomizer.
