You can easily reset your IQOS 3 DUO device by pressing and holding the Pocket Charger Button for 10 seconds (until lights fade out), then releasing. 
All Status Lights will turn OFF, blink three times, and progressively fade out, to confirm the RESET.

You can use the IQOS AC Power Adaptor from the previous device versions. However, IQOS 3 DUO USB cable hosts a USB-C port, which is different from that of IQOS™ 2.4 Plus.v

IQOS 3 DUO device does not require a full charge to work, however we recommend to fully charge the device before the first usage.
If the IQOS 3 DUO Pocket Charger is fully charged, you may use the Holder up to 20 times.
The Holder charging time is effective only if the IQOS 3 DUO Holder is fully charged the first time or after being fully depleted.

If the tobacco plug is stuck in your cap, remove by gently tapping the cap on a hard surface to extract the tobacco plug, or by using a cleaning pin.
If you use the pin, simply push the rod outward from the bottom part of the cap.
To prevent this issue, please make sure to always lift up the cap before extracting the used HEETS tobacco stick. 

If you have difficulties inserting the HEETS tobacco sticks in the IQOS Holder, we advise you to first check whether:
• there is any tobacco residue left in the Holder
• the heating blade is cleaned regularly
• the Holder Cap is fully closed

If the above is all right, you can try to pre-heat the IQOS Holder prior to inserting the HEETS tobacco stick:
- IQOS 2.4 Plus / IQOS 3 /IQOS 3 DUO:
- Press the Holder Button to start heating
- Wait for 2-3 seconds for pre-heating
- Gently insert the tobacco stick

- IQOS 3 MULTI:
- Open the lid
- Press the Button to start heating the device
- Wait for 2-3 seconds for pre-heating
- Gently insert the HEETS tobacco stick

Ultra-compact and precisely designed, HEETS consistently deliver tobacco taste, satisfaction and pleasure when heated with the IQOS Device.
 
The tobacco part consists of the carefully selected, finely ground and specially prepared tobacco that delivers the best taste while heated.

Non-tobacco part consists of:                                                                                                                                                                                                                       
• Cooling plug  - made of corn-based material also used in medical, food and beverage industries
• Air flow chamber – designed to hold the tobacco plug in place and transfer the aerosol to the cooling plug
• Protective wrap – protective aluminium wrap which helps to deliver a consistent taste experience
• Filter - similar to the mouthpiece filter of a cigarette. Made of cellulose acetate.

Yes, HEETS tobacco sticks contain nicotine, which is addictive.
Nicotine is naturally present in the tobacco used in HEETS. It is released in the vapor that is generated during the IQOS usage.

The taste of HEETS tobacco sticks is different from that of cigarettes because tobacco is heated rather than burned.
By heating the tobacco, the true taste of the tobacco is released.
HEETS tobacco sticks are made from a specially selected blend of tobacco in order to provide tobacco taste and satisfaction that replicates as much as possible what adult smokers expect.

The HEETS tobacco sticks are designed specifically for the IQOS devices. They have an optimal length, diameter and design for the IQOS Holder.
