Lynx NGT-9000s
Installation Manual
1.3.3 System Unlock Code
Unlock codes are required if installing and activating the TAS and Diversity options. The unlock codes
are 10 digit codes that are entered during installation using the Lynx MAT to install either of these
options. The unlock codes may be purchased and shipped with the unit. If the unlock code is not included,
contact L-3 Avionics Systems Customer Service to obtain the code. Be sure to have the Mode-S ID (e.g.
ICAO) available for the service representative. The unlock code is associated with the aircraft ICAO
address and will only work for that aircraft ID.
