products using high-density data cartridges and mini-data cartridges. This maintenance procedure prolongs
tape and head life and helps reduce read/write errors due to dust and oxidation.

Do NOT use petroleum-based cleaners (such as lighter fluid) or cleaners containing
benzene, trichlorethylene, ammonia, dilute ammonia, or acetone. These chemicals
could damage the keyboard's plastic surfaces.
Before removing the top cover, always disconnect the power cord and unplug
telephone cables. Disconnect telephone cables to avoid exposure to shock hazard
from telephone ringing voltages. Disconnect the power cord to avoid exposure to
high energy levels that may cause burns when parts are short-circuited by metal
objects such as tools or jewelry.
