Maintenance

Unplug all components before cleaning. Do not use liquid or aerosol cleaners. Use a soft, damp cloth to clean the microphones and controller.

If storing for an extended period of time, remove the batteries.

Troubleshooting

Audio

No dial tone

Ensure that the RJ-11 cable is connected to an analog line. Make sure the phone cable is connected to the Line jack, not the Set jack. If you are connected to a digital line through a telephone handset, take the handset off-hook. Run a system diagnostic check through RAV- Ware to be sure all RAV components are working properly.

RAV does not ring

Adjust the volume of the ringer. Check that the RJ-11 cable is connected. Verify that the dialed phone number is correct.

Muffled reception

Do not move the microphone pods while on a call. Move any items that might be blocking the microphones. Move closer to the microphones.

Far-end party cannot hear

Check the connections of all audio inputs. Check the Audio Mixer in RAV-Ware to make sure the correct audio paths are selected. Adjust the volume of the audio outputs.

Short silences, echoes or clipped speech on the far end

Adjust the equalization in RAV-Ware for each component.

Adjust the volume. Watch the meters. Make sure the loudest audio causes the meters to just enter the yellow zone.

Be sure equipment is placed correctly for the best sound performance. Refer to Chapter 1 for basic room design guidelines.

Controller

Controller doesn't communicate with the mixer

The RF Controller performs best when the RAV mixer is positioned within line of sight and with the antenna pointed up. Check the signal strength indicator in all areas of the room where the controller will be used.The signal strength indicator is on the LCD screen and the maximum number of bars is four.

For optimal RF connectivity, make sure the signal strength measures two or four bars in all operating locations. You can also use the RF Radio Test function on the Controller for a more detailed signal strength measurement. Refer to page 59 for more information.

To improve signal strength

•Verify that the mixer is within line of site

•Install mixer in the top space of the equipment rack

•Ensure the antenna is pointed up

•Do not install the mixer in a metal cabinet

You can also purchase a remote mount antenna to improve the signal strength when the mixer is located in a different room or in an enclosed metal cabinet.

Part number: 910-153-050

Be sure the frequency setting on the controller is the same as the frequency setting in RAV- Ware.

Cannot assign a speed dial number

Any phone numbers entered using the Controller are automatically assigned to speed dial location 0. Access RAV-Ware to assign speed dial numbers.
