Let the countdown to the end of analog television begin.
On Friday, all full-power television stations across the country will stop broadcasting in analog and switch to digital.
Of the country's nearly 1,800 broadcasters, 756 stations have already made the transition. In four days, the remaining 1,030 will join them in the digital age.
But about 3.5 million U.S. television households, or 3.1 percent, aren't ready yet, according to a May poll from Nielsen Media Research.
If you're one of the TV watchers who still needs to prepare for Friday's deadline, don't worry. Here are a few tips to get you set up and running in no time.
How To Make the Digital Switch
1) Before you panic and head out to your local electronics store, make sure your TV's not already digital-ready.
To help make the process a little easier, the broadcasting industry's DTV Transition Coalition created a searchable database to help you figure out if your television has a built-in digital tuner.
If you can't find it there, check your television for any labels or markings that indicate that it contains a digital tuner. Statements to look for include: "Integrated Digital Tuner," "Digital Receiver," "DTV," ATSC" or "HDTV."
Televisions that are 25 inches or larger, or were purchased since 2005, are more likely to have a digital tuner.
If your television was purchased before 1998 or is a smaller LCD set (15- to 18-inches) it probably has an analog tuner.
Also, TVs labeled as "HD-ready," "Digital Ready" and "Digital Monitor" may sound promising but don't necessarily contain a digital tuner.
From Analog to Digital TV
If you're still not sure if your TV has a built-in digital tuner, check the manual, other instructional materials or the manufacturer's Web site, or contact your consumer electronics retailer.
2) Once you know you have an analog television, weigh your options.
If you already have cable or satellite service, you're in good shape. But if you're only reliant on rooftop antennas or rabbit ears, you'll have to choose one of a few options to upgrade your TV for the new digital era.
In the $40-$70 range, a digital-to-analog converter box is the cheapest option, especially in this economy.
But if you're in the market for a new TV, anyhow, you could potentially find one with a built-in digital tuner starting at $200.
Or, for $20 or more a month (not including the cost of renting the equipment), you could subscribe to cable, satellite or other premium television services.

3) If you want to stick with your current TV and programming options, buy a converter box.
Walk into any consumer electronics retailer and they should be able to help you find an digital-to-analog converter box. They range in price from $40 to $70, but consumer advocates say you should be just fine with the lower-end models.
"Our reviews show that the cheapies are just as fine as the expensive boxes," Chris Murray, senior counsel for the Consumers Union, told ABCNews.com.
To help us make the transition to digital television broadcasts, the government created a program to subsidize the cost of the digital converter boxes.
According to the program's Web site, coupons are still available for eligible households. Applications can be accepted online, over the phone, by mail and fax. But because it usually takes nine business days to process and mail coupons, those who apply now will likely not receive their coupons in time for the June 12 deadline. Still, you can submit coupon requests until July 31, 2009 or until supplies run out.
Check Your Television Before You Make the Switch
4) Prepare your television for its high-tech upgrade.
Before you start to install the converter box, be sure to unplug your television. The converter box should come with set-up instructions, but you'll need your analog TV, the antenna you've been using (either indoor or outdoor) and the coaxial wire that connects the antenna to the TV. The new converter box will also include a coaxial wire and a remote control.

If you have trouble while connecting the converter box, go to www.dtv.gov or contact the FCC by e-mailing email@example.com or calling 1-888-CALL-FCC (voice) or 1-888-TELL-FCC (TTY).
Once you've connected the television to the converter box and the converter box to your antenna, plug the converter box and television into a power outlet. After tuning the TV to channel 3 or 4, you can use the remote that comes with the converter box.
Using your remote, choose the "set-up" or "menu" button to navigate to the "channel scan" option. This will allow you to search for the digital broadcast channels that are available in your area. (The owner's manual for your converter box will have more instructions on how to perform a channel scan.)
5) Don't give up if it doesn't work right away.
"It might not be plug and play," Brian Lucas, a spokesperson for Best Buy, told ABCNews.com. "You might need to experiment with that signal."
If it doesn't work immediately, Lucas suggested repositioning the antenna.
Consumer Union's Murray said that most people shouldn't need an antenna upgrade. But if you're more than 25 miles away from a broadcast station it might be necessary.
If you plug your address into Antennaweb.org it tells you the channels that are available in your location and the type of antenna needed for reception.
6) If you upgrade to a new digital television, recycle your old one.
Electronic products are the largest source of lead in municipal solid waste, according to Consumers Union. Older monitors can contain four to eight pounds of lead on average and the plastics that house the sets contain toxic and environmentally-damaging flame retardants.
If older analog sets still work, consider using them for videos, DVDs or gaming. If you must toss them out, check whether your municipality offers electronic waste recycling programs.
7) Finally, act now.
"It's a good idea to take care of this early," Best Buy's Lucas told ABCNews.com. "Setting it up now and getting that digital signal running will allow you to troubleshoot if you have to."
