Operation
Introduction
The SLB 406 is designed to provide world-wide alerting in emergency situations via the
Cospas-Sarsat System. The SLB 406 operates on two frequencies simultaneously – 406
MHz as the alerting frequency for the Cospas-Sarsat satellite system, 121.5 MHz as the
civilian homing frequency to aid SAR responders. Following is a description of the
operating instructions and functions of the SLB 406.
Deployment
In the storage configuration, the antenna is wrapped around the chassis of the ELT and
held in place with a snap on the Activation Lanyard. To deploy the antenna, simply
unsnap and pull away from the Activation Lanyard. The antenna may be rotated for best
position. The SLB 406 will provide the best transmission characteristics when it is placed
on a flat surface with the antenna oriented vertically.
The SLB 406 can also be held in the hand with the antenna oriented vertically. See
