FAQ
Tuning Cable Channels
The 232-ATSC 4 will skip encrypted channels automatically when you activate a channel scan.
You can skip scanning analog channels by pressing Select after you start the scan.
Typically, the digital channels will not use the same Guide numbers as a cable box.
If you can’t select channels, make sure that the channels have been scanned.
RGB/Component Video
Analog HD is output on either the RGBHV (VGA) or Component output. Use the front-panel menu to select
the desired output.
There can be “fluttery” lines at the top of the analog channel –this is closed captioning data.
Go to the Overscan menu and increase the value.
HDMI
HDCP is always off –not required for non-encrypted programs
If a monitor has issues with current resolution, 1080p/60 works best for newer models.
DVI
DVI compatibility is normally supported; you can manually select DVI from the HDMI-DVI menu.
Composite Video
Press the RATIO button on the IR remote to select the desired format for NTSC video
The onscreen menu also has Screen Format settings, generally only used when tuning an analog channel
Audio
Volume won’t affect digital audio in AC-3 or PCM modes PCM Variable supports level control
If there is no audio, make sure the volume is all the way up (and not muted).
Digital audio is sent as Consumer format, the Digital Audio menu can change to Professional format
A “motorboat” sound means the source does not support AC-3, change to PCM.
Power/AV
If the LCD shows only Power On, call CR Support for solutions
If you can’t change volume or channels and there is no video, first try an alternate power supply, call
Support if needed.
The tuner will display “Voltage Low” if the power supply is failing or low. Press SETUP, go to the Firmware
menu, and then press the Right arrow several times to see the exact voltage. There is a “Voltage High”
warning if the supply is significantly higher than 12 VDC.
IR Control
There can be interference from room fluorescent lights. Hold down SELECT on the remote. Pressing 4
selects normal 38 KHz IR, pressing 9 selects 57 KHz IR.
Check the front-panel IR Receive menu to see if it is turned on or off.
If there is significant IR interference, an IR-RXC Remote Sensor may be required, and cover the front-panel
IR sensor to reduce interference
Captioning
If the tuner is feeding a digital channel modulator, use Composite video to send captioning data.
If the site wants to see captioning on all TVs, turn the feature on in the tuner.
S37 Installation
See Support Blog on Windows 8-10 settings for S37 installation.
