PRODUCT OVERVIEW
The packaging includes:
• Compass unit
• Illumination
• Mounting kit

POSITIONING
SILVA 102B /H should b e positioned ver tically or s loping (ma x 30°). Vertical ly only, if a comp ensator i s fitted.
BULKHEAD MOUNT
The co mpass shou ld be positi oned where it can be easil y read from al l angles, e ven in darkness w hen illumi nated. Posi tion the comp ass as far as possible aw ay from iro n objects o r other
disturbin g magnetic s ources as lo ud speakers, win dscreen w ipers, ins trument s etc.
NB! SILVA s electronic ins truments do not distur b the compas s.
When c hecking fo r magnetic di sturbance, use a n ordinar y SILVA handhel d compass , held in the
fore -and-aft direc tion aroun d the intende d mounting si te. In most ca ses 0.5 to 1 met re betwee n
the com pass and the s ource of dis turbance w ill be sufficie nt. Do not for get to switc h on all
elec trical eq uipment nea r the compas s when makin g this check .
MOUNTING
SILVA 102B /H is intend ed for flush m ounting.
The co mpass must be moun ted exactly at righ t angles to the boat’s l ongitudin al directi on.
NB! Do not t ake It for gra nted that for in stance a bulkhead is at a right angle to the b oats long itudin al directi on. Drill a h ole by using the encl osed templ ate. The compass m ust have a cer tain
mount ing depth, ot herwis e the compas s’ expansio n membran e is affected, wh ich could lea d
lo leakage. L oosen fro nt plate of the c ompass by pr essing th e hatch on the bottom si de and
mount t he compass t o the bulkhe ad with the fo ur screws suppli ed.
COMPENSATION AND DEVIATION
Comp ensation i s recommended, if t he deviati on is more than 5 degre es, when th e compass is
in its normal mounting position.
If the er ror is less than 5 de grees, it i s sufficient to produce a d eviation t able.
Comp ensation i s made with th e two compe nsation adjuste r screws ”E /W” an d ”N/S” in order
to redu ce the errors cau sed by iron ob jects or ot her source s of magnetic d isturbance. Th e
compe nsation ad juster scr ews are situated at t he compass lower f ront edge.
When c ompensat ing, the boa t should be in an a rea that is not affe cted by per manent- or ele ctromagnetic disturbances.
1. Aim the boat d ue North an d turn the ”N/ S” screw until the compas s reading is 0°.
2. Aim th e boat due Eas t and turn the ”E/ W” scre w until the compass r eading is 90 °.
3. Aim th e boat due Sou th. If the compass d oes not show 18 0°, turn the ”N/S” s crew until th e
erro r is halved. (E .g. If the er ror is 6° - turn the screw until th e error is 3 °.)
4. Aim th e boat due Wes t. If the comp ass does not s how 270°, tu rn the screw until th e error is
halved.
5. Go through th e procedur e again and che ck the adjus ted values .
6. Check the compass e very 20 de grees and produc e a deviatio n table and de viation curve.
As the magne tic conditi ons in a boat ar e liable to cha nge, we reco mmend chec king of the com pass o nce a year and alway s after inst allation of equip ment which m ight affec t the compa ss.
NB! Do no t regard the c ompass as a n accurat e navigati onal inst rument un til the comp ensation is c arried o ut and the dev iation ta ble is prod uced. Whe never in dou bt, pleas e seek the
advi ce of a compa ss adjust er!
