Helpful Hints:
PBXport will not work with any telephone that has a keypad
in the handset.
If using a mixer you must use a "mix-minus" signal to the
Send input (Page 5)
You must set the A-B-C switch to the correct handset type
position for your particular telephone. (page 8)
You may use either front or back panel handset jacks but not
simultaneously.
Don't overdrive the Send input. Flashes of the -3 Red Send
LED indicate distortion, clipping and reduced separation.
If your telephone has an adjustable receiver volume control,
you should set this control to the "normal" position. If the
Receive audio meter on the PBX port is showing the red
–3 dB LED, you should turn down the volume on the base
of your telephone until you see only green LEDs.
