Message Delay (sec): Adjustable from 0 to 9 seconds in half sec increments. This is the delay from when the page
trigger output is activated until the start of the wave file is played. Adjusting this can eliminate cutting off the first sec-
tion of the wave file in applications where certain paging amplifiers require a second or two to power up and/or switch
to that audio source.
Memory Usage: The CTG-2's wave file memory storage is separated into 14 memory blocks and is displayed after
each wave file name under the column titled "Memory Usage". The memory blocks will fill with color after uploading a
wave file showing how much memory space was required for that file. Larger wave files will require multiple memory
blocks. To conserve memory storage space you can reduce the sampling rate of the wave file from 44K to 22K or 11K.
Note: Reducing the sampling rate will decrease the sound quality of the message/sound.
Missing Wave Files: If the CTG-2 does not have a wave file in its internal memory that is required by the PC dat file
you have open, "Missing Wave Files will be highlighted in red. To upload the missing wave file to the CTG-2, open the
drop down menu and click on the missing wave file. The file will then be automatically uploaded to the CTG-2.
Volume: The "Volume" drop down menu allows you to adjust and set the volume level of each individual wave file.
This is useful for matching the volume levels of each wave file or increasing the volume on specific wave files such as
evacuation sirens, etc.
Load All: In the "Tools" drop down menu, selecting "Load All" will upload all the wave files from the currently open
"CTG2 Wave Files" screen into the correct memory locations in the CTG-2.
Erase All: In the "Tools" drop down menu, selecting "Erase All" will erase all 14 wave file memory locations in the CTG-
2.
Save Vol: After adjusting the wave file volume levels (adjusted volume settings will be highlighted in red) select "Save
Vol" to save the volume settings for all wave files.
Play: Clicking on "Play" will signal the CTG-2 to play the selected wave file. This is useful for setting the volume lev-
els for each wave file.
Change Rate: In the "Tools" drop down menu, clicking on "Change Rate" opens the
"Rate/Size Calculator" which allows you to reduce the sampling rate of the selected
wave file to reduce the memory storage capacity needed.
Troubleshooting Communication Errors
1. If the USB status LED goes off while you are connected to the CTG-2, communi-
cation between the PC and CTG-2 has been lost. Close the PC software, unplug the
USB cable from the CTG-2 and power down the CTG-2. Reconnect power, plug the
USB cable back in and open the PC software again. Communication should be re-
established.
2. If you open the PC software with a CTG-2 connected, occasionally a communications error will occur between the
PC and the CTG-2 and a message will pop up saying the CTG-2 is missing some of its wave files, when they are not
missing. If you get this type of error message, close the software and re-open it.
3. If the CTG-2 displays "Pro" when the PC software is not open, momentarily power down the CTG-2 and the display
should clear.
4. If you open the PC software and a message says: "error on directory position 15", close the PC software and power
down the CTG-2. Reconnect power and open the PC software again.
