Benefits and purpose Simple replacement designed for HD870 singlehead systems, compatible with the SFHD62 and SFHD65 head generations. Factorytested before , with strict quality control to ensure reliable performance. Clear, userfriendly replacement workflow that can be handled by nontechnical personnel with proper guidance. Key features and requirements Function: optical head designed to read discs in compatible HD870 equipment. Compatibility: suitable for HD870 singlehead installations and the SFHD62 / SFHD65 head generations. Installation safety: must be completely disconnected from power before installation. The objective lens should not be touched or dropped during installation. Do not adjust the potentiometer yourself. Installation integrity: improper installation can prevent the disc from being read; ensure correct alignment and secure mounting. Important installation notes Before starting, ensure the device is fully powered down and disconnected. Do not touch or drop the objective lens during handling or installation. Do not attempt to adjust the potentiometer after removal or during replacement. If the installation cannot be performed correctly, reading the disc may fail until proper alignment is restored. Quality and reliability All units only after successful factory testing. Quality control processes are strictly observed to maintain performance and reliability. Use scenarios and applications service in a tech workshop: worn or degraded HD870 singlehead assemblies to restore disc reading capability in devices using SFHD62 or SFHD65 head generations. Field maintenance for HD870 equipment: technicians perform head replacement onsite to minimize downtime in production lines or diagnostic labs. Device servicing in data centers or labs: swap in the SFHD62/65 compatible head to maintain compatibility across HD870based systems during routine maintenance or part upgrades.
