PSIP. The Mag thread says...
For 2160/2160A/513/515: These units can search either analog or digital channels. If you have analog channels, start by entering a FOX analog channel #, then press OK. If no analog channels, arrow left to "CH." Arrow up/down to change it to "DTV." Enter a major DIGITAL FOX channel # in "Set Channel No." box (no subchannel digits). A Time Zone (TZ) menu pops up. Select your TZ, then press OK.
Open the Clock > Clock Setting menu and set your clock for 11:57am (not pm). You must press OK after setting the time, then quickly turn DVDR OFF.
You can set for 11:58am if you're in a hurry and have experience with this procedure already. However, the clock MUST be on 11:58am or earlier when it shuts down completely or it might not start a search at 11:59am, and complete shutdown takes ~15-20 sec after power-off. Don't use pm cuz that makes the date change to next day during the time search and affects the order of your current timer rec programs. Make sure you press OK or your time setting won't take.
Watch for auto time change within 2-3 minutes after "whirring" sound at 11:59.
At 11:59am clock time, the TV pic will change to a black screen and the DVDR will make a light "whirring" sound as the fan starts up and the tuner switches to your designated channel. If there's a time signal on that channel, you'll see the time change within ~2 min. or sooner. If no signal, the fan will stop at ~12:01pm and the TV screen will return to its normal "no signal" color, indicating search is over.
If you find an active time signal, make sure it sets the "correct" time and am/pm compared to some other clock in the house and leave it set that way. My analog PBS sets a time but it's always WRONG, whereas my analog FOX has been dead-accurate for 10 months... until just recently! DO NOT CHANGE THE AUTO CLOCK SETTING MENU TO OFF AFTER FINDING A GOOD MANUAL CHANNEL... just leave machine set the way it is now!
If no active time signal on FOX analog, try other known active channels.
Go back to Step 2 and try (1) FOX digital, (2) CBS analog, (3) CBS digital, (4) PBS digital, (5) PBS analog.
As a last resort, try any other suspects (except local access channels)... varies by locale. However, no one has reported other good channels.
If you do NOT get an auto time change on ANY channel, you have two choices:
Keep Auto Clock on Manual with either FOX or CBS (not PBS) in the channel-entry box to give your DVDR a power-backup time of 2-3 min. rather than the typ. 30 sec. when Auto Clock is set to OFF. (Also helps the 515 as mentioned in next subject below.) Correct time manually if/when it drifts. Don't use a local community-access or CATV channel cuz they might freeze your unit.
Give up extra power backup time and set clock to correct time and Auto Clock OFF. Correct time manually when it drifts. All clocks seem to run slightly fast. One person who might opt for this is a 515 user who has a lot of "freezes" that require him to pull the power cord and replug after full power drain, Soft Reset, in which case he'll have a shorter wait time (~1.5 hr instead of 2.5 hr).
FINAL STEP: No matter what the results were, check timer rec programs.
Check your existing timer programs to make sure changing the clock time didn't MOVE today's timer program to the bottom of the timer list, assuming it was PAST the time or day/date for that program. This can happen if you choose 11:59pm instead of am in Step 4 above. If you find today's program NOT back in normal top position, check the clock setting again and make sure the day/date is correct. Today's timer rec program will pop back to top position once you enter a correct date.
TIP: If your clock doesn't sync to the exact second compared to an atomic or other accurate clock in your house, go back to the 1st clock setting option and arrow right until you're over the minutes. Arrow up to 1 minute AHEAD of the atomic/accurate clock . Watch only the atomic/accurate clock and, exactly when it changes to that minute, press OK. The clock will start keeping time with the seconds in sync.
