1.7 Features
In order to operate the Mode-S transponder it is necessary to
request an ICAO 24-Bit Aircraft Address at the responsible
National Aviation Authorities. The received code must be
configured within the transponder (see chapter 3.4.2.1.2).

1.8 Safety-Conscious Utilization
For safe operation of the transponder the following notices have to be observed:
•The installation of the transponder into an aircraft should be carried out only by an authorized
installation company. The country regulations always have to be observed.
•Use the transponder only within the specified conditions, see chapter 7.
Power supply:
• Do not connect the transponder to AC sources.
• Make sure that the transponder is connected to the mandatory DC source, see chapter 7.
• Do not connect the transponder with reversed polarity to the DC source.
Circuit breaker:
• The transponder should be protected from the aircraft power supply by a dedicated 3 A circuit
breaker or fuse (slow-blow).
Excessive pulses on the DC bus of the aircraft may cause damage on electrical circuits of any installed
instrument.
Do not switch ON the transponder during engine start or shutdown.
1.9 Restriction for Use
The transponder is to be used only inside the declared limits.
