Appendix A: Troubleshooting
Problem: When a student microphone is activated, the CameraMan
Camera does not move.
Solution: 1. Verify that the PRM POWER switch is ON.
2. Verify the microphone is wired to the correct input on the
PRM and that the corresponding Location Preset is stored.
Recall the location with the Camera Control Keypad.
3. Verify that the BASE UNIT ADDRESS on the back of the camera
is set identically to the BASE UNIT ADDRESS on the front of
the PRM.
4. Verify that no microphones are “LOCKED” active.
For information on locking and unlocking microphones,
see Low Profile Microphone Manual
5. Verify that the camera is not already at the desired location.
6. Verify that the
Baud Rate
DIP switch #7 on the front of the
PRM matches the
Baud Rate
DIP switch #A7 on the Base Unit.
(DOWN=9600, UP=19200).
Problem: The camera is locked on one microphone and will not move
when other “press-to-talk” buttons are pressed.
Solution: Verify that the positive (+) and negative (-) leads on the
cable connecting that the microphones to the PRM are lined
up correctly with the contact closure leads on the PRM.
