Using External Devices
If you choose to use an external speaker, antenna, or alert system, use the external jacks on the back of the radio (ie: EXT SP jack, EXT ANT jack, or ALERT terminals respectively). You may purchase these devices at any local electronics store.
To connect the external devices, do the following:
1)Plug an optional external speaker
2)Plug an external antenna using an RCA pin connector or adapter into the
EXT ANT jack.
3)Plug the external alert system into the ALERT terminals.
a.To open the terminal holes, press in on the two buttons in the middle of the ALERT terminals.
b.Insert the two leads into the holes observing correct polarity of the external device. Make sure the leads are stripped to expose the wire.
c.Release the buttons to secure the leads.
