THEORY OF NAV-PAC OPERATION
NOISE FILTER / VOLTAGE TRANSIENT PROTECTOR WITH BATTERY
BACK-UP
The NAV-PAC is wired in series with the DC power to sensitive electronics and:
(1) Filters out noise interference on incoming power lines.
(2) Clamps voltage spikes and transients to a safe level.
(3) Provides battery back-up power during voltage drops due to starter motors
and momentary losses of power.

NOISE FILTER / VOLTAGE TRANSIENT PROTECTOR WITH BATTERY BACK-UP INSTALLATION AND OPERATION MANUAL The NAV-PAC is wired in series with the DC power to sensitive electronics and: (1) Filters out noise interference on incoming power lines. (2) Clamps voltage spikes and transients to a safe level. - Page 2 Warning of Imminent Loss of Power: A remote panel is supplied with the Maintenance-free solid state circuitry assures years of dependable service. NAV-PAC and its function is very important; it warns of loss of input power and • Conformal coated printed circuit board resists corrosion.
- Page 3 LED lights draw only about .01 amp each.) prevent discharge of the internal battery. In the event of a loss of DC input to the NAV-PAC, the “INPUT OK” LED will be extinguished and the “OUTPUT OK” LED will begin to flash. This indicates that the navigation equipment is being powered by the NAV-PAC’s internal battery only.
- Page 4 To reset this circuit input to the NAV-PAC must be restored. number starting "0435" was manufactured the 35th week of 2004, Be sure to Bear in mind that the NAV-PAC has another disconnect circuit which may cause mark the date of replacement on this sticker for future reference.
