TROUBLESHOOTING
ENSURE YOUR SOUND CARD AND SPEAKERS ARE WORKING
CORRECTLY BY TESTING WITH ANOTHER SOUND APPLICATION
The vast majority of PC based Recording installations take place
without problem. On rare occasions, due to the wide range of sound
cards available, problems can be experienced due to incompatible
software settings within the sound card control software.
Some sound cards have features that are switched by pressing
buttons (DTMF codes) on your telephone. This feature needs to be
switched OFF if you are using the Manual Call Recording option of the
CRU.
If you experience other problems with your sound card, that you are
unable to rectify, we would recommend that you replace your sound
card.
The Soundblaster range of sound cards from Creative Labs are
recommended as they are inexpensive and commonly available.
CRS SOFTWARE FAILS TO START RECORDING
* Ensure that your serial cable is correctly connected to your PC’s
COM port and also to the PC COM port of CRU-2.
* Ensure that your CRS software has detected the correct COM port
and that it is displayed on your CRS menu (see page 8).
FILES ARE RECORDED BUT ARE SILENT
* Ensure that you have correctly selected LINE IN or MIC as your
input source (see page 9).
* Move the REC slide bar on the CRS menu towards MAX until the
required record level is obtained (see page 10).
FILES WILL NOT PLAY BACK THROUGH MY SPEAKERS
* Ensure that MUTE IS NOT TICKED in Windows Mixer (see p 9).
* Increase the Volume Slide Bar for VOLUME and LINE IN or MIC.
* Increase the PLAY Slide Bar towards MAX on the CRS Menu.
* Experiment with Windows Mixer settings.
