Notes:
1. If you have devices that need access to the PTT line (e.g. some ATUs, SteppIR controllers, etc.), use
the key line interrupter supplied with your KPAK3AUX cable set. The interrupter breaks the pin 10
line so you can use the separate PA Key cable (see Figure 4 on page 14).
2. Pin 4 is not used but the wire is included in the KPAK3AUX cable.
Icom Cable
Various models of Icom radios use either a 13-pin DIN or a 8-pin DIN connector. Be sure to use the connector
that is correct for your radio. Pins not shown have no connection.
