Closed captioning lets you display the audio portion of a program as text on the TV screen. This is
useful to the hearing impaired or anyone who wants to watch a program without the sound.
There are two types of closed captioning available: C1 (caption 1) and C2 (Caption 2).C1 display the full
translation of the primary language in your area. C2 may be used as a source for secondary languages,
simplified English, or other translations transmitted in your area.
Closed captoning is not available on all channels or at all times. Only specific programs are encoded
with closed captioning information.

The following information will address TV antennas and attempt to give some insight into how
TV antennas and their application effect television performance. .
UHFNHF FREQUENCIES
VHF (CH 2 -13) and UHF (CH 14 -69) signals are nearly identical with one critical difference:
"wavelength." VHF wavelengths are longer than UHF wavelengths. Therefore, the best antenna
is one that closely matches the wavelength of the signal you are trying to receive.
Also keep in mind that VHF wavelengths are significantly reduced when obscured.
ANTENNAS
Following are a few points to consider in regards to installing and choosing an antenna:
Metallic Paint
Manufacturers of boomerang antennas warn users that painting antennas with metallic paint will
hurt performance. This is also true for foil antennas used in fiberglass high tops that are painted.
Outside Metal
When TV antennas are used inside low top van conversions, the TV signal can be obstructed by
the outside metal of the vehicle. This will diminish UHF performance and may eliminate VHF
reception altogether. However, depending on antenna's location and the direction of the vehicle,
some VHF signal may be received.
Loss of Signal
Loss of signal is another factor which should be considered. Every connection between the
antenna and the TV will reduce signal. Coax connectors improperly attached to antenna cables
will cause even more loss. Partially grounded roof rack antennas will also effect reception,
especially VHF.
Testing done on antenna systems has shown that as munch as a 10% loss of signal can be
measured across every connection. Multiplying this figure by the number of connections,
(antenna to VCR to Nintendo, to TV) equates to a significant reduction in signal. Splitters, A/B
switches and even the type of coax cable used will effect antenna performance.
Our televisions are also designed to be monitors as well. Some of our customer are taking
advantage of this feature by running RCA patch cords from the VCP to the TV audio/video
inputs. This reduces the amount of connections required and will improve reception.
The information in this bulletin is not intended to promote or discourage the use of anyone
antenna, but to caution. Approval of antenna performance and application, should not be given
without adequate testing in both VHF and UHF areas.

The following information will discuss DC power sources and how they affect to 12 volt DC
Audio and Video products.
DC (DIRECT CURRENT) POWER
A large number of our products are designed for 12 volt DC applications. The power is supplied
by a variety of sources i.e., the battery, converters, ignition systems and solar power.
General Specifications
Our general specification for the voltage range of operation is 10 to 16 volts DC. TV's and
VCP's (video cassette players) require slightly more than 10 volts to function properly. Normally
this 10.5 to 11 voltage requirement does not create a problem, but keep in mind the following
points:
,
~
c I
1
~
'~
Voltage
The voltage of a fully charged battery (engine not running) is approximate,y 12.5 VDC. Once a
load (items being powered represent the "load") is applied, the voltage will drop. How much the
voltage is reduced will depend on the following:
1. Current draw (amount of amperage) The higher the draw the greater the voltage will drop.
2. The size and length of the conductor (wire) supplying power
,0"
Amperage
A TV will draw considerably more amperage than a VC~ For instance, a 9" TV will draw
approximately 3.0 amps compared to a VCP that draws 1 amp while the taps is being loaded or
ejected.
Checking the voltage of a TV while it is playing shows an approximate 1 volt drop, (11.5 VDC)
The voltage at the VCP can be another .5 VDC (11 VDC) less than the TV.
In conclusion, operating these video products without the engine running will drain the battery
to the point where these products will perform unacceptably in a short period of time.
Converters
Many RV OEM's incorporate converters as a source of 12 VDG when connected to shore power
(110-120 VAG). Some models put out a very clean DG supply where others may have a
considerable amount of AG ripple under maximum load.
This AG ripple is filtered by the coach battery when connected into the circuit, but when the
battery is removed or disconnected the amount of AG ripple can create major problems for
audio and video products. Noise may result and often times in line fuses fail.
Ignition Systems
Unwanted noise generated from ignition systems used to be a big problem. However, with more
sophisticated filtering circuits designated into audio/video products, these problems are not as
wide spread .
Changes in wire harnessing also has contributed to the decline of application problems. One
rule of thumb is to use the same ground point for all related products. This will greatly reduce
the potential for alternator whine.
