Tighten nuts on the backclamp only slightly more than you can tighten with your fingers. Six inch-pounds of torque is sufficient. Overtightening may result in damage to the instrument and may void your warranty.  \n1. Location: The tachometer should be located at least 18” from a magnetic compass. Some interference (erratic operation) may be noticed on the tachometer during radio transmissions . This will neither damage a Faria® tachometer nor affect accuracy when not transmitting.  \n2. Be certain to use stranded, insulated wire not lighter than 18AWG that is approved for marine use.  \n3. Using a small screwdriver, SLIGHTLY depress and turn the selector switch on the back of the tachometer to the correct position to match the number of poles in the alternator (see label on the side of the tachometer) .  \nDepressing the switch too hard may cause damage to the tachometer! Be sure the selector switch has locked into the detent at the correct position by slightly rotating the switch back and forth with the screwdriver.  \nIf the number of poles is not known, consult the “Outboard Tachometer Application” chart or call Faria® Marine Instruments at (860) 848-9271 with make, model, HP, and year of the motor.  \n4.
