HE 1 HE 1 UPDATE HE 1 Important safety instructions Notes on the use and disposal of storage media You can use the supplied USB flash drive for storing data, including personal data. If the flash drive is sold/passed on or disposed of, the data once stored on it and then deleted using a standard delete method can be recovered with special software and be misused. We therefore recommend using special software for secure deletion of data to ensure that personal data is not misused. Please note that you yourself are responsible for the secure deletion of the data on your flash drive. We recommend backing up the data saved on your flash drive regularly. Sennheiser does not accept liability for damage or loss of data. Notes on servicing We recommend having the product serviced regularly (about every 3 years) to maintain the perfect sound reproduction of the electrostatic headphones and the tube headphone amplifier. Contact your Sennheiser partner to arrange for a complete revision and careful refreshment of the product (see "Contact" on page 4). The service card inserted in the rear cover of this instruction manual provides information on the servicing carried out. Notes on driver and firmware updates We recommend using the latest DAC (digital-to-analog converter) firmware for your tube headphone amplifier and the latest driver for your operating system (MacOS), Windows). DAC firmware and driver updates can be downloaded free of charge from the Internet at www.sennheiser.com/download or can be obtained from your Sennheiser partner (see page 18 and 45). Notes on the packaging We recommend using the original packaging to ensure safe storage and transport of the HE 1. Damage during transport is often caused by the use of unsuitable packaging. The original packaging of the HE 1 provides optimal protection and minimizes the risk of damage during transport. Alternatively, you can contact your Sennheiser partner to arrange for the transport of the HE 1 (see "Contact" on page 4). 9
