A person who has basic computer skills can be described as "computer literate". This can be described with variety based on whether one has computer skills on Mac or PC operating systems, and which programs they are well-versed in.
The Thunderbolt was, and still is, a wonderful siren. It is also a belt-driven pain to maintain, especially if mounted on a pole. Belts break and grease gives out so preventative maintenance kept the sirens going- when it was done. The Thunderbolt has a blower in a box and up top on a pole (more often than not) has another box with the chopper and rotator motor which make the noise and move the horn around. Federal Signal no longer makes the siren nor does it stock parts. However some businesses and enthusiasts specialize in keeping the existing units going. The rotator's design was used in Federal's 2001 sirens. Federal Signal Discontinued the Thunderbolt in Part because of the Frequent Maintenence required to keep the Siren Functioning Optimally....The Thunderbolt had many Parts that could Break.....the Number of Parts also Possibly Contributed to This....Besides having a Chopper and Rotator Motor...the Thunderbolt also used a Large Blower to Force Great amounts of Air through the Chopper to make the Siren Louder or "Supercharge" it. in 1988 the Thunderbolt's Replacement....the 2001 was Introduced.....it Required much less Maintence,and had Fewer Parts,Two Years Later in 1990 the Federal Signal Thunderbolt was Discontinued.
