Weather radar transceivers use a magnetron which is basically a cathode emission device. The magnetron is subject to deteriorization due to aging. Therefore, it is recommended to perform some type of periodic maintenance to detect and correct the effects of aging. This reduces the chance of an in-service failure.

An annual, routine test of the following parameters should made:

- Power output
- Transmitter frequency
- AFC voltage
- Sensitivity (MDS)

Ideally, the test should take place between December and March prior to the peak thunderstorm season.
Radar stabilization uses an aircraft's vertical gyro (if equipped) to maintain the selected radar antenna beam relative to the horizon. Therefore, while in a turn, the radar will maintain the selected tilt angle instead of changing in relation to turn.
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.
As of January 2010, the only Multi Function Displays that are compatible with the Primus 300 or Primus 400 radar systems are the Honeywell MFRD and the Universal MFD-640. For pricing and additional information on these MFDs, please submit an RFQ to SEA today.

Negotiating the exchange price of a unit only limits the allowable repair cap for the core unit. Southeast Aerospace's exchange transactions are based on the return of economically repairable core unit. Once the core is received and evaluated, the core repair cost incurred by SEA cannot exceed 80% of the original exchange price. That is, it cannot cost SEA more than 80% of the original OH/SV exchange price collected from the customer. Therefore, when and if an SEA exchange price is discounted, there is a risk that additional charges may be assessed once the core is returned and evaluated.
