Uninterruptible Power Supplies (UPS)

A loss of power while your HDTV is turned on can cause:
- Premature lamp burnout in case of LCD or DLP TVs. When you turn off your LCD or DLP TV the fan(s) that cool the Projector Lamp continue to run. In the event of power loss the fans will not run. If the heat is not dissipated from the lamp, lamp life is greatly reduced.
  - A special note about fans: Some TVs have a fan speed control. Sony calls this High Altitude (in the Setup menu) on or off. I recommend that you use the high speed (High Altitude on) mode whenever possible. Because the fan runs faster it makes a little more noise, but in most cases this is not objectionable.
- Loss of horizontal and/or vertical deflection in case of TVs that use CRTs
  - Loss of deflection can cause lines to be burned into the CRTs, requiring replacement of the CRTs.
- Using an uninterruptible power supply will allow you to turn the set off properly in the event of a power outage, saving hundreds of dollars in parts and labor.
- What is important in choosing an Uninterruptible Power Supply?
- Power Ratings - Bigger is better
  UPSs are rated in volt-amps (VA), but sometimes the manufacturer will specify watts. To determine the size of the UPS you need, add up all of the Amps ratings from your equipment and multiply it by 120 (120 volts). This is your power requirement. In most cases a UPS in the 700VA to 1000VA range (about 450 watts to 670 watts) will be acceptable. A larger UPS will allow you to power more equipment and/or give you more "run" time in the event of a power failure.
- Sine Wave Output
  The AC power provided by the local power company is a 60 cycle sine wave. Many of the less expensive UPSs provide power output that is either a square waves, rectangular waves, or a stepped sine wave. In electronics, whenever there is a sharp edge in the waveform many harmonics are generated. These harmonics can leak into the equipment thru the power supply and distort the waveforms that are being used to operate your equipment. These distortions can cause a variety of very strange problems. Avoiding the technical reasons, a square wave UPS is bad for your equipment, do not use a power supply that outputs a square wave.
- Where can I purchase a UPS?
  Office supply outlets and computer supply outlets are two good places. A true sine wave UPS is much more expensive than a stepped wave UPS. Factory refurbished UPSs are much cheaper than new ones. American Power Conversions (APC) sells refurbished UPSs online at http://www.refurbups.com.

TV Guide Plus

TV Guide Plus programming is carried on the local ABC affiliate, in our case WEAR TV 3.
Without a Cable box
Go thru the normal setup. When the TV is off it will find the TV Guide signal and download the information.
With a Cable Box
When you set up the Guide Plus it will ask you if you have cable. If you say yes, it will ask what brand the cable box is. This is important when you want to use the TVs remote control, or the Guide Plus features to control the cable box, but not necessary to acquire the Guide Plus information.
Important: When the TV is off, leave the cable box tuned to the ABC affiliate, in the Pensacola/Mobile area that is Channel 3!

Does that mean I can put a dish on my balcony, even though the condo owners say I can not? Yes! See the FCC rules concerning Antennas and Satellite Dishes.
