• Using the TCL GoogleTV remote, navigate Settings >  Channel & Input > Channels > Channel Scan
• The Channel scan settings options will be displayed as shown below. Select your country from the option list.  Note: Later on, if you need to switch countries, it will prompt you to enter a password, use the default password: 1234. 

• Proceed with the channel scan selection option:
  • Scan Automatically: Enter automatic channel search. This is the recommended option.
  • Manually Scan: Enter manual channel search. 

Tuner Mode: Antenna Channel Type: Digital & Analog
