A Cable Box is a device with a tuner that allows You to received channels that is not offered by Your rooftop antenna and is usually provided by Your cable company. You cable company hooks You to its service. The cable box receives an encoded signal and decoded it so You can watch the channels on Your screen. Some cable box descramblers are deemed illegal because they receive service while the subscriber isn't paying.
Nearly every box has a built in plug outlet which is intended for turning on and off TVs along with the box itself. You can plug any other electric device into the box, but You should never plug any extension cords or surge protectors into the back of the box as they might make the box overheat.
| Jerrold DPV/DPBB Instruction Manual |
The following is a manual that will help those who use a Jerrold Box pictured above. The boxes used in My area have a 4-digit display. On the 4-digit display, You will see MUTE near the lower left corner to indicate when the volume is turned off. On the top, You will see B P, which will be discussed at the end of this paragraph. The 4-digit display can display the time of day in either 12 or 24 hour format. I know also most boxes have a 2-digit display. The 2-digit display has P B. Since I don't have one in My house, I don't know much about it. However, I have tried the 2-digit display box and most function work similiarly. I will list each function in easy to follow steps in a chart that tell You what You will see on either display. The indicators (or "dots" as most people say) on the display light up when special conditions are in effect. B indicates when an alternate source or cable system is selected, meaning 17 without the B dot and 17 with the B dot might be different. The P lights up when the channel is parentally controlled or when the time is displayed, it indicates PM. Since the B P is on the top for 4-digit models, I will write the displays like this 12:3'6 to indicate 12:36 PM.
In addition the the remote, the Jerrold Box has many common control on the top middle right. These control include the numberic keys, Channel Up and Channel Down, MUTE, POWER, A/B, PC/PM, Select, Learn, Enter, and F.
The remote has the same keys plus PROG (or PRGM on some remotes), Channel Recall, Favorite Channels. Many remote also have a TV button to turn off the TV. 0 cable companies will give You a generic remote. The company that makes these generic remotes is called US Electronics. The buttons are described below.
ON/OFF Button
Turns the box on or shuts it off. Numeric
Keys
Allows You to jump to any channel directly. Press 2 and then 1 to go
to channel 21 or if the channel number is a single digit, press 0 and then the
number (such as 0 and then 6 for channel 6)
Channel Up and Channel Down
Moves one channel at a time
continuiously in order at an increasing or decreasing rate. Some channel numbers
might be skipped, this is usually set up by the cable company to skip any empty
channels. After the highest channel is reached, the box returned the the lowest
channel number in the system and vice-versa.
MUTE Button
Shuts off the audio of any channel.
A/B Button
Switches between two signals or two channel systems,
this is not available in all areas.
PC/PM Button
Sets parental controls, or when setting the timer or
clock, switches between AM and PM.
Select Button
Order an event. A 4-digit code can be set to prevent
inadvertant orders.
Learn Button
Programs passwords for parental control and ordering
events. If You forget any code, You can call the cable company to reset it if it
is rented. If You own it, make sure You remember Your password.
Enter Button
Confirms any information entered into the box.
F
Brings up the prompt for most of the functions for the box.
These buttons are available on the remote control.
Volume Up and Volume Down Controls the audio of the cable signal. On the 4-digit display, their is a level range of 0-32
Favorite Channels (FC or FAV)
Allows You to go through in order.
The box counts both channels from A and channels from B, since they might be
different channels. Thus, the following is a sample order of the way the
channels are organized, 2A, 7A, 15A, 19A, 3B, 5B, and 87B. The favorite channel
button will cause the box to go the next highest channel number according to
this rule.
Last Channel (LC or <CH) The Last Channel also has a unique rule. Its use ignores Channel Up or Channel Down presses after You select a new channel. For example, Say You're watching channel 52. You switch to channel 68. You press Channel Up two times. Even though now You're on channel 70, the box will return to channel 52 after You press Favourite Channel. After that, if You Channel Down a couple times and press it again, the box will go to channel 70. I agree that it's a bit complicated.
Program (PRGM or PROG)
This allows You to program either Your
favorite channels into the box or use the sleep timer function.
TCP/TIMER
You can program the box to channel channels, turn on and
off, and order event on its own at a certain time with this button. It works
well in conjunction with Your VCR when You want to record multiple programs on
different channels when You are not home.
TV
This button is only available on the US Electronics remote. To
program a code for a remote controlled TV to turn it off and control its volume,
press F (on the remote), TV, enter the code, press TV, and then ENTER. If You
don't know the code, press F, TV, Select, TV, Select, TV...etc. until You find
the correct code for Your TV if You don't know it. To return the remote's volume
control to the box, press F, CATV, 000, and then CATV. Their are codes to make
this type of remote control other cable boxes (on power, volume and channel
selection only.) Right now I don't know all the codes, so currently I have no
list.
The box allows users of old TV sets to control via its own volume control system. Volume control is only displayed on a four digit display.
