Lights should be wired to an appropriately fused 12-volt circuit in your electrical system (i.e. running light circuit).
Connect one wire to ground and one to positive, observing polarity is not necessary with Explorer compasses.
Compensation
A built-in correcting magnet system consists of two sets of magnets fixed to two adjusting rods with slotted ends. The
slots should be horizontal before starting the adjusting procedure. A small non-magnetic screwdriver is provided for
this purpose.
Before starting compensation, make sure you have a suitable location (see Testing Your Chosen Location).
Step One. With the compass in its intended position, but not finally secured, (see Mounting the Compass) select a
course on your chart using two fixed aids that are within ten degrees (10°) of the Northeast-Southwest line. Try to
select this course so that you can maneuver your boat “down range” of the marks selected (See example).
Step Two. From a position down range of the Northeast-Southwest marks, and keeping the marks lined up, run the
boat visually along the Northeasterly course selected. Turn the left hand Comprod
until the compass reads correctly.
Step Three. Simply repeat steps 1 & 2, except this time,
using an Southeast-Northwest course and the right hand
Comprod.
Step Four. Check compass alignment by running the boat in
a Southwesterly direction, again keeping the mark
lined up. If the compass is not correct at this time, there is an
alignment error. To correct, rotate the compass itself to
remove one half of this error. Repeat steps 1, 2 & 4 until your
Northeast-Southwest line is correct then repeat step 3.
Step Five. Install fastener (s), taking care not to disturb
alignment.
ALL Models
If 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.
Maintenance
Ritchie 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.

Ritchie’s night-lights are designed to last for years of use. If you need to replace one, contact the factory with the model &
