To utilize the signal battery polarity option, remove the jumpers in applications where the external
signaling battery is positive (+) with respect to chassis ground. In cases of positive (+) signaling
battery applications, both jumpers must be removed.
To install the MA-305C module adapter, perform these steps:
1.
At the rear of the chassis, insert the adapter into the same slot position in which the VF-25 module
has been installed.
2.
Once it is seated securely, secure the unit with screws provided.
3.
Plug the connector into the adapter.
