The Main Functions & Operations
1.Activated Mode&Attaching a new atomizer:To wake the device from power off state, tap the Fire button. The VT25 uses the resistance of the atomizer to calculate the temperature of the heating coil. It continually looks to see whether a new or changed atomizer has been connected.
If you are using temperature protection, be careful to only attach new atomizers that have cooled to room temperature to the device. If a new atomizer is attached to the VT25 before it has cooled down, the temperature may read and protect incorrectly until the new atomizer cools.
When you connect a new atomizer or disconnect and reconnect your existing atomizer, the VT25 will prompt you to confirm this change. When you fire the first time, before activating the VT25 will prompt “New Coil? UP YES/DOWN NO”. When you see this prompt, if you have attached a new atomizer, press the UP button. If you have disconnected and reconnected the same atomizer, press the DOWN button.

2.Locked mode: Pressing the fire button five times with less than 0.7 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.Power Locked mode: 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. This mode prevents accidental power level changes due to the buttons being pressed while in a pocket. To exit Power Locked mode, hold the up and down buttons for two seconds.

5.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.

6.Max Temperature Adjust: 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. To save the new temperature setting and exit, press the Fire button.

Error Messages
The VT25 will indicate a variety of error states.

Check Atomizer: The VT25 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 VT25 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 Protected: The heating coil reached the maximum allowed temperature during the puff. If this happens, the VT25 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 VT25 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 VT25 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 VT25 has on board temperature sensing. It will shut down and display this message if the internal board temperature becomes excessive.


Auto power down

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.


Charger
The VT25 connects the USB charger with 1A current,configuring the quick charge
function so that only needs 1.5 hours to be fully charged.
(it’s the normal phenomenon that the body were fevered by charging due to the quick charge function)
