Channel Tuning and Presets 

 

The new auto-scan capability of the 232-STSi allows the user to search for channel frequencies, select a TV 

standard, and save as a numbered channel Preset that includes the frequency and TV standard. Using this 

feature, channel Presets can include broadcasts from neighboring countries with different audio standards.  

 

Scanning and adding channel presets can be performed via RS-232 

commands, Tuner Helper software, and the optional IC-RC IR wireless 

remote. For simplicity, the following instructions are based on the IC-RC 

remote pictured on the left.  

 

Zeroing Out Presets 

Press the “0” key, then the Arrow Left key (Delete Preset) to clear all 

Presets in memory. 

 

Set Starting Frequency 

The 232-STSi will scan up or down starting from the current frequency in 

memory, and will stop when it finds a station with a valid video signal.  

Scanning stops when it hits the lowest or highest frequency, it does not 

cycle back to the beginning or end. 

 

To start at the lowest frequency, unplug the RF feed then press the Down 

Arrow to Scan Down.  

 

Select TV Standard 

Press the Top key to step through TV standards – the tuner will display 

on-screen text to confirm which standard is active. The first standard to 

appear is the current setting. 

 

PAL B/G/H A2 

 

PAL B/G/H NICAM 

 

PAL D/K NICAM 

 

PAL I NICAM 

 

Search for Broadcasts 

Press the Arrow Up to search for the first broadcast frequency. 

 

Save Channel Preset 

To save the current channel and TV Standard, enter a Preset number 

between 1 and 125, and then press the Right Arrow key to save.  

 

To do a quick save, press Right Arrow without a number. The tuner will 

save as the last channel deleted or the next highest available channel. 

 

Press Arrow Up or Arrow Down to search for the next frequency. 

 

Changing TV Standard 

If the found channel has good video, but no or poor audio, it may be using 

a different TV Standard than your current setting.  Press the Top button 

until the audio quality improves.  

 

If you are changing the standard of an existing preset, it will display as “0” 

until you return to the current setting or save the preset. 

 

Delete Preset 

Enter a channel preset number, and then press the Left Arrow key. If you 

delete a preset by mistake, press the Right Arrow key immediately to 

restore the preset. Enter a “0” and Left Arrow to clear all Channel 

presets.    

 

View Channel Presets 

Press the  and Channel- keys to view currently saved Channel 

Presets.
