External MIC / LINE Input (EXT socket)

As shipped, the external MIC / LINE input is set to a sensitivity of 0 dBu. Switching the input sensitivity to –45 dBu for the connection of a PTT-microphone is only possible by closing two internal soldering-bridges. Therefore, you have to perform the following steps:

1. Disconnect the paging console from the power supply.

2. Detach the bottom plate (6 to 8 screws, depending on the paging station model).

3. Close the soldering-bridges “A” and “B” according to the diagram on this page.

4. Re-attach the bottom plate.
