The I/Q Select function provides automatic or manual tracking of inverted and
non-inverted digital QPSK signals. When set to Automatic, the I/Q Select function
automatically tracks the received digital signal and inverts the signal, as required.
When set to Inverted, the received digital signal is always inverted. Conversely,
when set to Non-Inverted, the received digital signal is never inverted. The I/Q
Select function is normally set to Automatic. The I/Q Select Inverted and
Non-Inverted settings can be used to automatically reject unwanted signals.
To set I/Q signal inversion
Step 1. Move to I/Q Select and press SELECT to display available settings
(Automatic, Inverted and Non-Inv). The default setting is Automatic.
Step 2. When the desired setting is displayed on-screen, move to Exit and press
SELECT, or press 1 and then press SELECT to change the current setting.
A pop-up menu displays Save options.
Step 3. Press 1 to save the new setting (YES), or follow the on-screen instructions, as
required.
Available options: Press 1 to save the new settings (Yes), or press 2 to discard all
changes (No), or press 3 to cancel the operation (Cancel).
Repeat the above action to change the I/Q Select setting. Unless otherwise recom-
mended, I/Q Select should normally be set to Automatic (default). If you are un-
sure about which setting to use, contact your dealer/reseller, or local service pro-
vider. For a list of default receiver settings, see Table 7.
