NCS-C411 Trunking Delay Module
Instruction Sheet

Introduction
The NCS-C411 Trunking Delay Module installs between any RAD port of the NCS-
C250/C251 & the NCS-C150 or the RAD1 port on the NCS-C151 and a Trunking Radio.
The purpose of the module is to delay the transmitted audio and PTT release while the
Trunking Radio acquires a channel from the Trunking Radio System controller. This
prevents voice transmissions from being lost or “chopped” during the channel assignment
(trunking handshake).
