Remark s :
• When there i s a b l a ck dot on the " s ign a l dire ction a rrow" it i s a n S RP s ym b ol, s o there will b e a reference to the s ign a l

• All reference s to norm a l gro u nd s (Gro u nd s ym b ol s witho u t a dditi on a l text) a re not li s ted in the reference li s t, thi s to keep
it conci s e.
• S ign a l s th a t a re not us ed in m u ltiple s chem a tic s , bu t only onc e or s ever a l time s in the sa me s chem a tic, a re incl u ded
in the S RP reference li s t, bu t only with one reference.
Additional Tip:
When us ing the PDF s ervice m a n ua l file, yo u c a n very e as ily s e a rch for s ign a l n a me s a nd follow the s ign a l over a ll the
s chem a tic s . In Ado b e PDF re a der:
• S elect the s ign a l n a me yo u w a nt to s e a r ch for, with the " S elect text" tool.
• Copy a nd p as te the s ign a l n a me in the " S e a rch PDF" tool.
• S e a rch for a ll occ u rrence s of the s ign a l n a me.
• Now yo u c a n qu ickly j u mp b etween the different occ u rrence s a nd follow the s ign a l over a ll s chem a tic s . It i s a dvi s ed to
"zoom in" to e.g. 150 % to s ee cle a rly, which text i s s elect ed. Then yo u c a n zoom o u t, to get a n overview of the complete
s chem a tic.
P S . It i s recommended to us e a t le as t Ado b e PDF (re a der) ver s ion 6. x, d u e to b etter s e a rch po ss i b ilitie s in thi s ver s ion.
