Break audio line. J2 input goes to mic pin J1output to radio.
(leave the shielded ground wires disconnected. on audio)
Power use a 1k ohm resistor from 12v dc on pwr switch.
Ground run the ground wire to board ground
test and set echo level.
this will work for any radio. if the echo needs 12v instead of 8v remove the 1k resistor and just use a 1n4001 diode on the power wires . some models require 12v some are 5-8volts.

  1. Download the SubInACL tool and install it in the %windir%\system32 folder. The %windir% placeholder represents the Windows operating system folder. For example, C:\Windows.
  2. Start Notepad, and then copy and paste the following commands:

    @echo off

    subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=administrators=f /grant=system=f

    subinacl /subkeyreg HKEY_CURRENT_USER /grant=administrators=f /grant=system=f

    subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=administrators=f /grant=system=f

    subinacl /subdirectories %windir% /grant=administrators=f /grant=system=f

    @Echo =========================

    @Echo Finished.

    @Echo =========================

    @pause
  3. Save the file as Reset.cmd.
  4. Right-click the Reset.cmd file in File Explorer (in Windows 8.1 and Windows 8) or Windows Explorer (in Windows 7 and Windows Vista), and then click Run as administrator. In Windows XP, double-click the file in Windows Explorer.
  5. Wait until the execution finishes, and then try to install the update again.

Echo wires diagram

why waste your money on an echo board .you should buy an echo chamber . They operate on the outside of the radio so people that don't know how to wire one in can still have one.the echo board should have come with schematics,if it didn't you may have to google it to get the schematic you need.

Grants 8-track tape player schematic?

Grants was simply the retailer for that unit, and not the manufacturer. It may well be that, possibly with minor cosmetic variances, the seame device was sold by other retailers such as K-Mart, Jamesyay, and so forth. So... in order to have a chance at obtainiong a schematic, it would help to know the device manufacturer.

Becasue the device is an electronic device manufactured for sale in the USA, it would have been required to meet FCC specifications regarding radiated signal attenuation. AS such, it should have an FCC Device ID number on the equipment somewhere. The FCC Device ID number can often be used to identify the manufacturer and sometimes the manufacturer's design or model number.

When i go into windows updates i get a error saying error found code 80070005 what do i do

The error code 80070005 usually means that you do not have enough permission to install updates.


First please confirm you have logged on an account with administrative privileges.


If the issue still occurs, lets' try the following method to reset the permissions:


1. Please download the subinacl.msi file from the following link and save the installation patch onto the Desktop:


http://www.microsoft.com/downloads/details.aspx?FamilyID=e8ba3e56-d8fe-4a91-93cf-ed6985e3927b&displaylang=en#AffinityDownloads


2. Please go to the Desktop and double click the downloaded file.

3. Please select the C:\Windows\System32 folder as the Destination Folder during the installation. Later we will use this tool to reset the permission settings on the current machine.


Note: If the UAC (User Account Control) window is prompted for permission to continue, please click Continue.


4. Click Start, in the Start Search bar, type: "notepad" (without quotes) and press Enter.

5. Copy the following commands and then paste them into the open Notepad window:


@echo off


subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=administrators=f

subinacl /subkeyreg HKEY_CURRENT_USER /grant=administrators=f

subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=administrators=f

subinacl /subdirectories %SystemDrive% /grant=administrators=f


subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=system=f

subinacl /subkeyreg HKEY_CURRENT_USER /grant=system=f

subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=system=f

subinacl /subdirectories %SystemDrive% /grant=system=f


@Echo =========================

@Echo Finished.

@Echo =========================

@pause


6. After pasting the above commands, please close the Notepad window. Choose Save when you are prompted to save the file. Type "reset.bat" as the file name and choose Desktop from the left panel as the save location.

7. Refer to the Desktop and right click the reset.bat file, and then choose "Run as administrator."

8. You will see a DOS-like window processing.


Note: It may take several minutes. Please be patient. When it is completed, you will be prompted with the message: "Finished, press any key to continue".


Try to install the updates again.


This issue can be also caused by third-party security programs such as firewalls and anti-virus software. You can disable or remove them to check the issue.

My ZTE cdma1X modem is not working on windows 7.

Apparently, one of the Windows updates is causing corruption of the Access Control List (ACL's) in the registry. I had entire sections of my registry nodes that lost the ACL'S.

While I was researching the problem, I came across a website where someone had a similar problem with getting windows OS programs/services to run and they discovered that there was some registry corruption and missing ACL's.

There are two different options that I ended up doing to get the system back in operation.

It seems that running one or the other alone will not fix the problem, but doing both should get you back in service.
  1. Make a backup of your registry (and a complete backup of the system wouldn't hurt either!)
  2. Go to Microsoft's website and download a program called subinacl.exe from this site; http://www.microsoft.com/downloads/details.aspx?FamilyID=e8ba3e56-d8fe-4a91-93cf-ed6985e3927b&displaylang=en
  3. Install the subinacl.exe (it downloads as an MSI file).
  4. Copy the code below into a text file and then name the text file reset.cmd.
  5. I copied the command file to my temp folder to run, but as you can see from the cmd file, it contains the path to the executable subinacl.exe.
@echo off
title Resetting ACLs...
cd /d "%ProgramFiles%\Windows Resource Kits\Tools"
echo.
echo Resetting ACLs...
echo (this may take several minutes to complete)
echo.
echo ==========================================================================
echo.
echo.
subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=administrators=f /grant=system=f
echo.
echo.
subinacl /subkeyreg HKEY_CURRENT_USER /grant=administrators=f /grant=system=f
echo.
echo.
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=administrators=f /grant=system=f
echo.
echo.
echo System Drive...
subinacl /subdirectories %SystemDrive% /grant=administrators=f /grant=system=f
echo.
echo.
echo Windows Directory...
subinacl /subdirectories %windir%\*.* /grant=administrators=f /grant=system=f
echo.
echo.
echo ==========================================================================
echo.
echo FINISHED.
echo.
echo Press any key to exit . . .
pause >NUL

3. As this command file runs it will show you the status of the reset and create a log that you can go back into and inspect for problems.
4. When this command file completes, you then need to open a command window (using Run As Administrator) and run the following command;
secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose >c:\temp\secedit_output.txt (the redirect of output echos the programs output to a text file, but secedit also creates a log file. The program will show you the location of the log file when it is done).

These two actions combined will reset the permissions on the registry nodes back to their default settings.

Reboot and check your Event Log service... at this point it should be running.

After effects of this process which happened to me, were that the Network List Service would not run... I still had network and internet access, however the Network icon in the task notification area had a Red X, and mouse over displayed a tooltip that said "Server Execution Failed". This was a result of resetting the ACL's.

The Network List Service (netprofm) would not run because it did not have permission to run.

In order to correct this issue, you must open the Component Services snap-in and drill down under Computers/My Computer/DCOM Config/netprofm (this is for Vista!) and right click the node, and select Properties.

Click on the Security tab and make certain the correct user names are listed and that they have the appropriate permissions. I have 4 users listed with the same permissions; (your mileage may vary )
  1. Administrators - Perms; Local Launch, Local activation
  2. Interactive
  3. Local Service
  4. System
Next, go to the Identity tab and ensure that The System account (services only) is the item that is checked. Make sure the changes you make get applied.

Restart your computer so the ACL's are refreshed.

Once you come back up from the reboot, things should be pretty much back to normal.

You may find a stray program here and there that may need to have it's permissions reset, but you should be operational.
