If any problems arise, please refer directly by email or phone to the manufacturer or send Herpifix together with a description of the defect to: Courage + Khazaka electronic GmbH, Mathias-Brüggen-Straße 91, 50829 Köln, Germany.
Your Herpifix comes with a 2 year guarantee. If any defect occurs within the guarantee period we will repair it free of charge.
Since Herpifix is free of chemicals and gentle to the skin, it can also be used during pregnancy. The used current lies significantly below the legal limit.
Children should be old enough to articulate the problem themselves. Use the slider on Herpifix to select the lowest possible current for them.
Some battery types are less than a millimetre too short, thereby disconnecting the contact. Please use another battery type or send in your Herpifix to have its contact spring replaced free of charge. Send it to this address: Courage + Khazaka electronic GmbH, Mathias-Brüggen-Straße 91, 50829 Köln, Germany.
Depending on the skin type, the status light might indeed get weaker or even go off when Herpifix is used on the lips. This does, however, not affect the effectiveness of Herpifix. If the status light is on when your Herpifix is removed from the skin, there is no defect.
Normally, you will feel a slight tingling sensation. If you regard this sensation as painful, just use the slider to lower the current of your Herpifix.
There are no known side effects. In rare cases, the treated tissue feels slightly numb for a few minutes after the application.
The affected skin area must be moistened before you apply Herpifix. This is necessary for Herpifix to have an effect. Should you still feel no tingling sensation, just use the slider to start with a higher current.
If you still feel no effect, please check if the green status light is on when you push the function button. If the light is off, either the battery is empty or there is a technical defect. In case of any defect, please send Herpifix with a description of the defect to: Courage + Khazaka electronic GmbH, Mathias-Brüggen-Straße 91, 50829 Köln, Germany.
Rechargeable batteries have a slightly lower current than regular batteries and discharge rather quickly. They are therefore not very suitable for use in Herpifix.
There is no limit to Herpifix’s durability. Approximately every 1,000 applications, you will need a new battery.
