In relation to NE (New) parts, many OEMs change their prices and availability without any notice to dealers or the industry. Therefore, through the REQUEST or RFQ indication, we ask that customers contact us for the most accurate price and availability.

In relation to SV & OH parts, the used parts aftermarket in the aviation industry is not an infinite supply. It is a dynamic, constantly changing market that is significantly affected by and susceptible to highs and lows in supply and demand. Therefore, although we attempt to, at times, we are unable to predict the exact moment when an item may be available. Once again, through the REQUEST or RFQ indication on our website, we ask that customers contact us for the most current and accurate price and availability.

Virtually all 406 MHz beacons incorporate a self-test mode of operation. Standard Self-Tests of beacons usually involve pressing a button or lifting a lever on the beacon and holding it for a few seconds. This usually results in the beacon flashing an LED or Strobe and/or creating an audible sound that indicates that the internal circuitry of the beacon is functioning correctly. You should always carefully follow the beacon manufacturer's instructions when carrying out a self-test as it is possible to get false results or inadvertently trigger a false alarm if perform the self-test incorrectly. If the beacon fails, then you should contact the beacon manufacturer or an appointed service agents for further advice and instructions.

Emergency Locator Transmitters (ELTs) are distress radio beacons which transmit location information about aircraft directly to Search and Rescue (SAR) forces letting them know that the owner is in grave and imminent danger.

A UIN is a Unique Identifier Number that is programmed into each beacon at the factory. The UIN number consists of 15 digit series of letters and numbers that make up the unique identity of the beacon. The UIN is on a white label on the exterior of the beacon. The UIN is also referred to as the Hex ID.

You should check the local regulations of any place you plan to visit with your beacon. Some countries require you to have a radio license and some countries even have restrictions on the use of beacons. However, if it's a true emergency, then you should always activate your beacon.

If a problem is detected in the ELT, the LED will produce a coded signal. The LED will flash in order of importance with approximately .5 to 1 second pulse between each coded signal if multiple errors are present. The coded signal and related problems are as follows:

• 1 flash indicates that the system is operational and no error conditions were found
• 3 flashes indicate a bad load detection. That is, an open or shorted condition on the antenna output or cable has been detected. This could be caused by faulty or intermittent RF connection or a problem with the antenna installation
• 4 flashes indicate that low power has been detected. That is, output power is below 33 dBm (2 watts) for the 406 MHz signal or 17 dBm (50 mW) for the 121.5 MHz output.
• 5 flashes indicates that the ELT has not been programmed.
• 6 flashes indicate that the G-switch loop between pins 5 and 12 have not been installed. If this error is present, then the ELT will not activate during a crash.
• 7 flashes indicate a battery problem. The ELT battery has too much accumulated time (> 1 hour). The battery may still power the ELT however it must be replaced to meet FAA specifications.

Southeast Aerospace has full bench test and programming capabilities for all Artex (Cobham) ELTs. Please contact the SEA Service Dept for any ELT service questions.

Even though the battery pack expires 5 years from the date the ELT is shipped from Artex, there are other factors that take priority. The Artex manual states that the battery pack must be replaced with a new battery pack in the following situations:

• After use in an emergency
• After an inadvertent activation of unknown duration
• When the total of all known transmission exceed 1 hour
• On or before the battery replacement data as indicated on the battery label

If any of these conditions are met, the battery must be replaced.

Artex batteries contain a microchip that records total activation time and number of activation times. The ELT tester will show this information when the unit is tested.
