Unfortunately finding life on another planet would be easier than
locating an ancient (electronic years) PLX-500 user guide. However, I
happen to have one of those ancient writings (no, it wasn't in a cave at
the Dead Sea), albeit a bit tattered and yellow, so I'll try and give
you a rundown of it's various features.
The top buttons for headset/handset and mute, and listening volume wheel
are pretty self-explanatory. Now let's talk about connecting the
PLX-500 to your phone and the other amplifier features.1) Disconnect
the telephone handset cord from telephone base and insert the PLX-500
modular plug into the handset jack on the phone. You then insert the
coiled handset cord into the
back of the PLX-500 base (there's only one place it can go into).
2) Plug the cord from the headset into the jack in the
front of the PLX-500.3)
On the back of the PLX-500 base there are two switches (1-2 and 3-4).
These are used to configure your PLX-500 to your phone (most electronic
single and multi-line phones, such as Panasonic, will use setting 1 and
4). You will have to configure the PLX-500 to your specific phone.
Having connected your PLX-500 to your phone, put on your headset, press
the headset button on the base, lift the handset of the phone cradle and
listen for a dial tone. Adjust the switch settings until you hear the
best dial tone.
4) Remember that your PLX-500 uses batteries located under a cover on
the bottom of the base (some phones will work without your PLX-500
needing batteries, check configuration before installing batteries).
Speaking of the cover, there is a small plastic screwdriver attached to
it that you use for adjusting the volume of your microphone. That
adjustment is located on the back of the PLX-500 base next to the
configuration switches.
Hopefully this gets your PLX-500 up and running.Good luck from
