your ManualGPS provide headings based on COG course over ground Compasses provide heading based on the direction the boat is actually pointed Because of tides currents and winds the boat may not always point in the same direction as COG Pick a time and location that will minimize these effects Because the GPS calculateCOG based on current and past positions you will see greater heading accuracy while traveling at higher speeds We recommend at least 10 warrant all Ritchie Magnetic Marine Compasses to be free of defects in workmanship or materials If within five years of purchase date a compass fails to give satisfactory service it will be repaired or replaced without charge This warranty does not cover breakage through accident or misuse Replacement or repair will be made if the

designed to be mounted on STEEL HULL Vessels Special compensation is required and you may need to hire a professional compass adjusterShock Mounted Models 453 Bare designed to be mounted inside a pilot house Do not mount them where they will be exposed to direct contact with salt compasses have two builtin Compensators A compensator is a brass rod with a slotted end and two magnets The slots should be horizontal before starting the adjusting procedure A small nonmagnetic screwdriver is provided for this purpose On some models the compensators are covered by two small plugs Simply remove them to access the slotsBefore starting compensation make sure you have a suitable location see Location Testing GuidelinesIf you feel that the deviation on your boat is of an unusual nature the services of a professional compass adjuster will be a wise investment To assure accuracy on all headings check for deviation every thirty degrees and record any deviation on a deviation card available at We recommend checking at the start of each boating season for deviation and any time newequipment is added near the compassMethod 1 With the compass in its intended position but not finally secured

nonmagnetic fasteners reassemble the compass Make sure you follow the Surface Alignment adapters and mounting hardware may be required to mount your compass to a pedestal Please contact the pedestal manufacturer for the proper mounting procedureDo not loosen or remove the 8 or 10 screws nearest the dome Fluid will escape and damage Mount models have either slotted holes or a clamp built into the base to allow for easy AAlignment adjustments If there is a clamp make sure it is tight before reinstalling the housingThese compensation rods are used to correct your compass for deviation When testing a location you do not want preset corrections in your compass so neutralize the comprods by setting the slotted ends in a horizontal position Begin your test by holding the compass away from any possible interference and observing the compass reading Then move the compass into position carefully keeping it pointed in the same direction If the compass reading is different without a change in direction you are observing deviation You need to find a location that has less than 15 degrees of deviation on the 4 cardinal points if you intend to adjust your compass using the compensator rods After finding a location you shouldtest for intermittent changes in the magnetic field With the compass mounted temporarily in its intended position try moving the steering wheel throttle controls or anything else that might cause deviation It is also advised to turn electrical devices off and on Please be advised that a changing magnetic field can not be corrected with compensation and you will need to find another location for your compass Important notes about care must be taken to mount the compass so thatthere is no 223Aalignment error224 223Aalignment error224 is a constant error on all headings caused by the compass not being pointed in the same direction as the boat One recommendation is to temporarily mount the compass using one fastener so if an alignment error is detected it is easily corrected Masking tape can be used as a reference or to keep the compass steady during installation The remaining fasteners can be installed when you are satisfied with the alignment If your compass came with mounting screws and they do not meet your needsSELECT MOUNTING HARDWARE THAT IS NONMAGNETIC Most quality stainless steel and solid brass fasteners can be used If you are unsure test them with a magnet It is important that you use the mounting gasket included with each Flush and Bulkhead model We do NOT recommend the use of bedding compound since some brands contain chemicals that could damage the compassMost models have builtin lights which will require routing the wire or wires to your power sourceNight Light WiringMost models are supplied with a 12volt night lighting system To connect lights to a 24 or 32volt system external dropping resistors are available Some models are available with 24 volt lighting eliminating the need for an external dropping resistor Lights should be wired to an appropriately fused circuit in theelectrical system ie running light circuit allot 1 amp for the compassSome models have two lights connect both of them to the same circuitFor Models withBlack Zipcord Wire the black wire withthe white stripe to positive and the all black wire to ground Gray Zipcord Wire the copper colored strands to positive and the silver colored strands to ground Jacketed wire Wire the red wire to positive and the black wire to compasses require very little care To remove salt spray deposits or dirt rinse the entire compass with clean fresh water and wipe carefully with a damp cloth Important Note Never Use Chemical or Abrasive Cleaners Installation Compensation and Maintenance Instructions In USAAll Magnetic Compasses are vulnerable to magnetic interference which will produce errors called deviation It is the OwnerOperator andor Helmsman222s responsibility to make sure the compass is properly installed and compensated Compensation is the act of correcting for deviation Magnets speakers microphones etc ferrous metals steel iron etc and current carrying devices are common causes of deviationIt is important to understand that magnetic compasses point toward Magnetic North There is a difference between Magnetic North and True North and that difference is called variation Variation differs depending on your geographical location and can bedetermined by referring to a local chart Please read the Instructions completely before beginning Guidelines The compass should be close enough to the helmsman and positioned below the helmsmans line of sight so it is easily read during normal operation Direct Read Dial or CombiDamp Dial models will allow the compass to be mounted higher near or at eye level Surface Alignment errors can develop and performance degraded when alignment guidelines are not metDeck Surface and Flush mount modelsYou will need a flat and level surface when the boat is on a level keel Many boats have a curved or slanted mounting surface and if this is the case a fairing block must be used to bring the compass to a level position Bulkhead Dash Mount modelsIf you are mounting to a bulkhead that is not perpendicular 90260 angle to the centerline of the boat andor not vertical 90260 angle to the waterline of the boat when the boatis on a level keel a fairing block must be used to make the compass soNote Some models are designed for slanted mounting surfaces off vertical Please reference your Mounting Template for Mount modelsIf you are mounting to a bulkhead that is not perpendicular 90260 angle to the centerline of the boat or a horizontal surface that is not level 223side to side224 a fairing block must be used to make the compass so Note Bracket Mount models can be leveled 223front to back224 within the Mount modelsThe mounting surface is usually predetermined by the pedestal manufacturer Various adapters and mounting hardware may be required Please contact your pedestal manufacturer for details Deviation Guidelines Select alocation that has no more that 15 degrees deviation on any of the four cardinal points N S E and W see below 223Location Testing Guidelines224 Most compasses have a builtin compensation system that will correct for fixed deviation up to 15 degreesIt is important to realize that proper compensation is not possible when a compass is subjected to a magnetic field that is variable Some shipboard devices can cause varying magnetic fields Devices such as windshield wipers high current carrying wire andeven some steering wheels must be considered when selecting a location for your Testing Guidelines Use your compass to test a location Most models havetwo brass rods near the bottom of the compass which rotate 360 degrees the slotted ends may be all that is visible CAUTION
