Trouble-Shooting
With the Manual R.P.M. Counter you have acquired a state-of-the-
art product. There may be troubles or problems, nevertheless. The-
refore, we would like to explain to you how you can clear possible
troubles:
Problem
No display, although
instrument is switched on
Laser does not function
Measured value too low
Maintenance
The Manual R.P.M. Counter is maintenance-free except for the
need to replace the battery and to clean the housing and the lens (of
the display window) from time to time. Please use a clean, fluff-free
antistatic cloth for cleaning the instrument, for cleaning the lens, use
a cotton bud or a spectacle-cleaning tissue.
Warning!
Do not use carbon-containing cleansing agents
such as benzenes, alcohol etc. as they attack the
surface of the housing. Furthermore, fumes produ-
ced are detrimental to health and explosive. Do not
use any screw-drivers or metal brushes for clea-
ning.
