1.00 en The dynamic reaction of the squelch functionality may be unsatisfactory; in individual cases this may influence the dual watch functionality or the reception of extremely short radio transmissions ("Double-Click" for confirmations)07/14/2011
1.00 en Using dual-watch requires switching between the active and the standby frequency. Therefore, it may happen that calls on the active frequency cannot be monitored completely. As a result we recommend not to use dual-watch in airspaces where continuous listening watch is required03/06/2013
