PERFORM AN OPERATIONAL TEST
1. Connect the Hx1 or Hx2 to AC Mains (J).
2. The unit will complete a self test.
3. A dot should be present on the front of the display (K) if the phone line is properly connected. If a minus sign
is displayed, the unit does not detect the line voltage and your wiring should be checked. If you are testing an
Hx2 with two POTS lines connected, make sure a dot is visible on both displays.
4. Press the Hybrid ON button (L). A dial tone should be present on the hybrid’s output and RCV bargraph meter
(M). If you are testing an Hx2 with two POTS lines connected, this step should be performed for each line
independently.
5. Verify correct mix minus operation at this point by noting that the RCV bargraph (M) shows the dial tone at
a nominal level, and that the SND bargraph (N) shows only the microphone or audio present on the device
feeding the Hx SEND IN. You should only see dial tone on the RCV meter. If you see dial tone on both SEND
and RCV meters, check your mix minus.
6. Press the Hybrid OFF button (O) to end the test.

YOUR SETUP IS COMPLETE!
That’s it! You are now ready to experience the Telos Hx1/
Hx2 for optimal caller audio quality.
1. To make an outgoing call, make sure that the hybrid is off (dot on the display (K)). Using the POTS phone
attached to the PHONE jack, seize the line, wait for a dial tone, and dial the desired number. When you are
ready to place the caller on the hybrid, press the ON button (L), wait for the hybrid to take the caller and hang
up the POTS phone.
2. To screen an incoming call, simply answer the call on the POTS phone attached to the PHONE jack on the rear
of the Hx. When you are ready to place the caller on the hybrid, press the ON button (L), wait for the hybrid
to take the call, and hang up the POTS phone.
