This instruction show how to customize the song numbers in a playlist. It applies to CAVS JB-199 III, JB-199 IV, JB-199 mini, and JB-199 mini II models.

Open the playlist in ‘My Server’ or in a playlist slot (1 – 10).
Highlight/mark the song (or all songs) that you wish to change the song numbers of. You can use a single click to select a single song, single click followed by Control-Clicks for additional songs, or use Click followed by Shift-Click for multiple songs.
Right click on the highlighted song(s) and you will see a popup menu with following choices.

• Index – Index all the songs as currently listed starting from 1 and sequentially thereafter.
• Index with Start Number – For a highlighted song, index it with a start number inserted and sequentially thereafter.

Only the above three methods are allowed for renumbering the songs. Manual editing individual song numbers are not allowed for possible user errors.

This instruction shows the most common causes of no audio problem in CAVS karaoke player.
The setting is as follows:
• CAVS Karaoke player is connected to an external sound system using the analog (Red and White) RCA connectors (left most) on the back panel.
• CAVS Karaoke player is turned on and playing a song.
• The external sound system is turned on and set to correct input/output.
When experiencing no audio, check the following settings:
1. In the control panel of the karaoke program, go to Tools > Settings and set the ‘Sound’ to “Primary Sound Driver”.
2. In the control panel of the karaoke program, set the ‘Volume’ level of music to ‘50’ or higher. Refer to the User Manual to find the Volume level control.
3. In the Windows, go to Start > Settings > System > Sound and set the ‘Output’ to ‘Speakers (Realtek® Audio)’.

The karaoke program keeps closing after starting. And resetting the Windows Registry by running Regedit does not help.

The karaoke program is likely tangled in the initial configuration due to incomplete Windows updates or user errors.
1. Open the File Explorer in Windows and go to Documents > JB-199IV or JB199Mini or PlayCDG Online (depending on which karaoke player you are working on).
2. Right click on the file JB-199IV.ini or JB199Mini.ini or PlayCDGOnline.ini. If the file name extension .ini is not showing, click on View at the top of the File Explorer and check “File name extensions”.
3. Select Delete from the menu to delete the file JB-199IV.ini or JB199mini.ini or PlayCDGOnline.ini.
4. Restart the karaoke program.
5. The karaoke program will restart with the factory default setting. Go to Tools > Setting and configure your options.

How to set a Task Scheduler in Windows to reboot the JB-199 player automatically once a day

1.Type in ‘Task Scheduler’ into the search field of the Task bar. The Microsoft Search will show the ‘Task Scheduler’. Click on the ‘Task Scheduler’.
2.In the next screen, click on ‘Creat Basic Task…’. When a popup window appears, type in the name and description such as ‘CAVS JB-199…’ to indicate its purpose for your reference.

This instruction show how to customize the song numbers in a playlist. It applies to CAVS JB-199 III, JB-199 IV, JB-199 mini, and JB-199 mini II models.

Open the playlist in ‘My Server’ or in a playlist slot (1 – 10).
Highlight/mark the song (or all songs) that you wish to change the song numbers of. You can use a single click to select a single song, single click followed by Control-Clicks for additional songs, or use Click followed by Shift-Click for multiple songs.
Right click on the highlighted song(s) and you will see a popup menu with following choices.

• Index – Index all the songs as currently listed starting from 1 and sequentially thereafter.
• Index with Start Number – For a highlighted song, index it with a start number inserted and sequentially thereafter.

When the karaoke program in a JB-199 player or PlayCDG program is not functioning as expected, one can reset the Windows Registry of the program to refresh it as follows:

1. Close the karaoke program program.

2. At the Windows desktop, click on Start and type in \”Regedit\” followed by Enter into the Search Programs and Files field.

3. You will be asked \” Do you want to allow the following program to make changes to this computer?\”. Click \”Yes\”.

4. A pop up window of Registry Editor will appear. Double click on HKEY_CURRENT_USER.

5. Double click on \”Software\”. Right click on \”CAVS Multimedia Inc.\”Select \”Delete\”.

6. You will be asked \”Are you sure …\”Click \”Yes\”.

7. Close the Registry Editor.

11. You will be asked \”Please check your internet connection to update the online status.\” Confirm that you computer has internet connection and click \”OK\”.

12. The karaoke program will start. Click on the Help button at the top left corner and select Online Upgrade.

13. Follow the instruction to upgrade to the latest version of the karaoke program.

14. Having refreshed the karaoke program, you need to reset the program options to your customized setting. For the Customer Interface or 3D Customer Interface, go to Tools > Setting at the top left corner and select your options. You should also load your song list, most likely the Master Playlist, into \”My Server\” that is found on the lower left section of the program sections.

This instruction shows the most common causes of no audio problem in CAVS karaoke player.
The setting is as follows:
• CAVS Karaoke player is connected to an external sound system using the analog (Red and White) RCA connectors (left most) on the back panel.
• CAVS Karaoke player is turned on and playing a song.
• The external sound system is turned on and set to correct input/output.
When experiencing no audio, check the following settings:
1. In the control panel of the karaoke program, go to Tools > Settings and set the ‘Sound’ to “Primary Sound Driver”.
2. In the control panel of the karaoke program, set the ‘Volume’ level of music to ‘50’ or higher. Refer to the User Manual to find the Volume level control.
3. In the Windows, go to Start > Settings > System > Sound and set the ‘Output’ to ‘Speakers (Realtek® Audio)’.

The karaoke program keeps closing after starting. And resetting the Windows Registry by running Regedit does not help.

The karaoke program is likely tangled in the initial configuration due to incomplete Windows updates or user errors.
1. Open the File Explorer in Windows and go to Documents > JB-199IV or JB199Mini or PlayCDG Online (depending on which karaoke player you are working on).
2. Right click on the file JB-199IV.ini or JB199Mini.ini or PlayCDGOnline.ini. If the file name extension .ini is not showing, click on View at the top of the File Explorer and check “File name extensions”.
3. Select Delete from the menu to delete the file JB-199IV.ini or JB199mini.ini or PlayCDGOnline.ini.
4. Restart the karaoke program.
5. The karaoke program will restart with the factory default setting. Go to Tools > Setting and configure your options.
