Mounting

The following mounting schemes are preferred:

Front loading, mounted vertically
Front loading, mounted horizontally with eject button on the right.

NOTES: Mounting angle should be less that 25° with front bezel up or down.

The preferred mounting schemes are the same for both model numbers (FD-05HF-5630 and FD-05HG-5661).

Cleaning the magnetic head may improve the data's reliability when the diskette drive is used in a dusty environment. In this environment, clean the magnetic head surface periodically with a dry-type, double-sided cleaning diskette every 1 to 3 months. Do not use a cleaning diskette that is damaged. If data errors occur frequently under normal conditions, cleaning is recommended.
