FliteCard updates
Returning the unit for service
PAGE 30
Repair of the Northstar M3 is performed at the factory. Factory service
includes a complete checkout and recalibration. Shipping charges are the
only costs for factory repair of a unit still under warranty.
FliteCard updates are made available on a 28-day update cycle. Install
updates by removing the unit from the instrument panel (use a
flat-blade screwdriver to loosen the retaining rod through the hole in the
front panel). In the Northstar M3, turning the retaining rod moves the unit
the last half-inch when inserting or removing the unit. Turn the rod to seat
or remove the unit—do not damage the threads by forcing the unit in or
out. Complete instructions are given in Section Three of the Northstar M3
GPS Approach Reference Manual. Press the button on the right side of the
M3 to eject the card. Fully insert the new card, and replace the unit in the
panel.
If you return a unit to the factory for repair, and you want the
latest update to be installed at the same time, you must
include payment to cover the cost of the update (unless the
unit is eligible for a free update). Purchase order numbers
from authorized Northstar dealers also are accepted. Call
Northstar for pricing.
An RMA number is required for returning any units to the Northstar fac-
tory. Packages received without an RMA number will be returned. Contact
your Northstar dealer or the factory to obtain an RMA number.
Securely pack the unit in the original Northstar shipping carton, and return
it to the address shown on page 29. Include your name, complete shipping
address, daytime telephone number, complete description of the problem,
desired return date, and shipping method. If shipping method isn't speci-
fied, units normally will be returned in about one week by UPS ground
transportation. If you require faster service, use air express and specify
your requirements. In emergencies, we can usually meet any reasonable
request.
New units won't be supplied to replace those that have failed. Dealers
returning units for credit, instead of repair, will be assessed a 15% restock-
ing charge.
