The KMD-540 is the actual MFD unit included in the KMD-550/850 systems. Therefore, KMD-540 + Install Kit & Database = KMD-550. And, KMD-540 + KAC-501 radar module + Install Kit & Database = KMD-850. The KMD-550 and KMD-850 are merely system reference designations. The actual MFD unit does not have the KMD-550/850 part on it.

The KAC-501, 502, 503, and 504 modules can be added and removed to the KMD-540 display unit very easily. Labeled screws are removed from the side panel and the panel is slid back. A screw on the top for the locking bar is removed, the bar is turned 90 degrees counter-clockwise and then pulled up through the top of the unit. For detailed instructions, please view this page from the KMD-550/850 Installation Manual.

Southeast Aerospace exchanges are based on the return of an undamaged, economically repairable core unit with identical part number as the unit shipped to the customer. An "economically repairable" core is defined as one where the cost to repair/overhaul (or Repair Cap) does not exceed 80% of the original SV/OH exchange price billed. Should the Repair Cap exceed 80%, the customer will be billed the additional amount. In the event this amount exceeds the Outright Price for the unit, the customer would only be billed the difference between the Outright Price and SV/OH Exchange Price with the core returned as-is to the customer.

Here is an example of such a transaction:

$1000 Exchange Price charged to customer
$1000 x .8 = $800 Maximum Allowable core repair charge or Repair Cap

$2000 Cost to repair core unit
- $800 Less Core repair cap
---------
$1200 Additional billing amount.

2200.00 Total Cost of transaction

Please Note:
SEA offers exchange on new items as well. However, repair cap as indicated above is still based on SV/OH exchange price.
