2.5 Installation Testing
The Unity 4600 has a number of installation tests that may be performed from the front
panel. From the Home screen, press the right arrow until the Installation Testing screen is
displayed.
RF input
check This test is used to verify an RF connection to a properly functioning LNB at any RF port.
Perform the check as follows:
1. Press ENT from the Installation Testing screen to bring up the RF Input Check screen.
2. Press ENT again to display the input level estimate at RF Port 1. This will be an average of
the estimated levels at each of the twenty-four domestic transponder center frequencies.
3. Press the right-arrow button repeatedly to display the input levels at RF Ports 2, 3, and 4 as
well.
4. Press ESC to return to the RF Input Check screen.
Audio/video
check This test puts out a video test pattern and audio test tones to allow verification of video and
audio connections. The video pattern is vertical color bars. On Port 1, the audio is a slowly
pulsing (triangle-wave) tone with a higher frequency on Right than on Left. On Port 2, the
audio is a slowly pulsing (sine-wave) tone also with higher frequency on Right than on Left.
On each port, the audio tones alternately pulse (~1 second) left then right, then repeat. Use
the following steps to enable or disable this audio/video test mode:
1. From the RF Input Check screen, press the right-arrow button to bring up the Audio/Video
Check screen.
2. The Audio/Video Check screen will indicate that the test mode is either "Enabled" or
"Disabled".
3. Press ENT to switch the test mode between "Enabled" and "Disabled".
4. Press the left-arrow button to return to the RF Input Check screen or ESC to return to the
Installation Testing screen.
DTMF Setup This test allows the setup of DTMF tone levels and verification of connections to cue
equipment.
Note: DTMF output capability not offered on equipment manufactured after 10/22/07.
Use the following steps to set the DTMF level:
1. From the Audio/Video Check screen, press the right-arrow button to display the DTMF
Setup screen.
2. Press ENT to display the DTMF Test Tone screen and begin output of the DTMF test
tones. The tones (actually tone-pairs) are played out at about one-second intervals from 1
through 9, 0, *, #, A, B, C, D, and then repeating.
3. Press the arrow buttons to adjust the volume. Up-arrow or right-arrow to increase volume,
down-arrow or left-arrow to decrease volume. The number of black squares on the LCD
indicates the current volume.
