The Main Functions & Operations
1.Activated Mode&Attaching a new atomizer:To wake the device from power off state, tap the Fire button. When you connect a new atomizer or disconnect and reconnect your existing atomizer, the DNA 40 will prompt you to confirm this change. When you fire the first time, before activating the DNA 40 will prompt “New Coil? UP YES/DOWN NO”.
2.Locked Mode:Pressing the fire button five times with less than .7 seconds between presses will cause the device to enter Locked 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 5X”. To exit Locked mode, press the fire button 5 times.

3.Stealth Mode:While locked, holding the fire and down buttons simultaneously for five seconds 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.


4.Right Mode and Left Mode: While locked, holding the fire and up buttons simultaneously for 5 seconds flips the display. This allows for maximum flexibility in designing the mod, as well as accommodating left handed use. This setting is stored to internal flash memory, and remains if power is removed.


5.Atty Lock Mode:In the case of temperature control function ,holding down both the up and down buttons for five seconds will enter into Atty Locked Mode.In this mode ,the power is in Adjustment Mode,but the resistance doesn't change with the change of temperature.While using ordinary heating wire,holding down both the up and down buttons for two seconds will place the device in Power Locked mode. In this mode, the mod will operate normally, but you will not be able to change the power setting.

6.Temperature Adjustment Mode:From Locked Mode, holding down both the up and down buttons for two seconds 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 to adjust the max temperature. The max temperature can be adjusted to below 200 Fahrenheit if switched Fahrenheit into Celsius, VT40 will be display the Celsius by this time.On the opposite,Celsius can be switched into Fahrenheit by the same time.After setting temperature,press the fire button to save settings and exit temperature adjustment mode.

7.Auto Power Down Mode:The screen will be at full brightness while firing. After 10 seconds with no button presses, the screen will dim. 30 seconds after the last button press, the screen will fade out and the device will go into sleep mode. To wake the device, press the fire button.

8.The Default Temperature Mode(450° Fahrenheit)
To change the limit,Please follow the steps below.
1)      Lock the device by pressing the Fire button five times.
2)    Hold down the UP and DOWN adjust buttons for two seconds.
3)    After two seconds, the maximum temperature will be displayed, and the UP and DOWN buttons should be released.
4)    Use the UP and DOWN buttons to adjust the maximum temperature
5)    When the display shows the desired maximum temperature, press the Fire button to exit temperature adjust mode.

Error Message
The VT40 will indicate a variety of error states.
Check Atomizer: The DNA does not detect an atomizer, the atomizer has shorted out, or the atomizer resistance is incorrect for the power setting.

Shorted: The atomizer or wiring are short circuited.

Weak Battery: The battery needs to be charged, or a higher rate battery needs to be used. If this happens, the DNA 40 will continue to fire the atomizer, but will not be able to provide the desired wattage. The Weak Battery message will continue to flash for a few seconds after the end of puff.

Temperature Protection: The heating coil reached the maximum allowed temperature during the puff. If this happens, the DNA 40 will continue to fire, but will not be able to provide the desired wattage.

Ohms Too High: The resistance of the atomizer coil is too high for the current wattage setting. If this happens, the DNA 40 will continue to fire, but will not be able to provide the desired wattage. The Ohms Too High message will continue to flash for a few seconds after the end of puff.

Ohms Too Low: The resistance of the atomizer coil is too low for the current wattage setting. If this happens, the DNA 40 will continue to fire, but will not be able to provide the desired wattage. The Ohms Too Low message will continue to flash for a few seconds after the end of puff.

Too Hot: The DNA 40 has onboard temperature sensing. It will shut down and display this message if the internal board temperature becomes excessive.

NOTICE TO USERS:
The temperature reading is the average temperature of the atomizer coil, and care should be taken to construct the heating coil so that the temperature is uniform, without hot or cold spots. Ensure that the coil does not short to itself.
