6. button one additional time The temperature limit will read OFF This will also disable the prompt when a new atomizer is attached Preheat When the DNA 25 is used with a temperature sensing atomizer an additional feature called Preheat is activated No vapor is produced when the temperature is below the boiling point of the liquid Preheat applies extra power until the heating coil is up to operating temperature to shorten the delay between pressing the fire button and generating vapor Because the preheat is temperature based it will not overheat or burn the vapor Attaching a New Atomizer The DNA 25 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 DNA 25 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 DNA 25 will prompt you to confirm this change When you fire the first time before activating the DNA 25 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 F

10. or manufacturers outside the United States the DNA 25 is available as a special order with Celsius units instead of Fahrenheit Minimum quantities apply Contact Evolv for details Operation Basic operation of the DNA 25 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 25 has a small 69 diagonal blue OLED screen The screen is attached to the main board by a flexible cable allowing freedom in the design of your device Please use caution when handling the screen and design the device so that the cable will be secured or strain relieved in operation The normal and special operating modes shown on the display are discussed below The DNA 25 will automatically detect whether a temperature sensing Nickel 200 or standard Kanthal etc coil is attached Temperature Protected Watt setting The power level currently set on the DNA 25 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 Ohms display The resistance of the atomizer attached to the device This is measured only when the unit is supplying power to the atomizer At other times it shows the most recent measurement Non temperature Prote
11. rature 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 Because wattage not temperature controls vapor volume large vapor volumes can be produced without unnecessarily high temperatures Temperature Protection is most helpful if the atomizer begins to dry out the user pauses during a puff the beginning or end of the puff or if the wattage setting is inappropriate for the attached atomizer In normal operation when the device is not firing the maximum temperature setting is displayed on the screen When the device is firing the actual average temperature of the coil is displayed on the screen By default the Temperature Protection setting is 450 Fahrenheit To change the limit 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 The maximum temperature is adjustable between 200 Fahrenheit and 600 Fahrenheit To disable the temperature protection entirely adjust the limit up to 600 degrees then press the UP
12. s recommended Either a lithium ion or a lithium polymer type can be used Any battery used should be rated for a MINIMUM of 10 amps continuous discharge current High C rated lithium polymer or IMR cylindrical cells are strongly preferred Make sure that all contacts and connections are capable of handling at least 10 amps Charger Evolv offers an accessory DNA Charger which is USB powered and provides a 500 milliamp charge current Other chargers can also be used The use on an onboard charger is optional a removable battery will also work Mounting The DNA 25 has onboard switches for adjusting the power level and activating the output Each of these functions also has optional through hole pads for using remote buttons The DNA 25 features mounting rails This allows the DNA 25 to be screwed clamped or slotted into a device The mounting rails are 075 wide and are removable If the mounting rails are removed the outline of the DNA 25 is identical to the DNA 30D and DNA 20 To remove the mounting rails use sharp flush cutting clippers and trim the rail away one section at a time A PCB de paneling tool is ideal to remove the rails in volume production Breaking the mounting rails off by bending could damage the board and should be avoided if possible The mounting rails have 063 diameter holes drilled for mounting screws 0 or M1 6 screws are recommended Mechanical Dimensions 1 300
