Sennheiser HE 1 Instruction manual HE 1 - Page 43

Servicing the HE 1 | Replacing the ear pads HE 1 Servicing the HE 1 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). By default, servicing includes the replacement of the ear pads, headband padding and amplifier tubes. The service card inserted in the cover of this instruction manual provides information on the servicing carried out. Replacing the ear pads For reasons of hygiene, you should replace the ear pads from time to time. 1. Grasp behind the ear pad and carefully pull it up and away from the ear cup. 2. Place the new ear pad onto the ear cup. Observe the orientation of the circumferential edge and make sure that the seam points downwards. 3. Attach the ear pad to the ear cup by pressing gently around the ear pad until it locks into place. 1 2 3 41
