EV-200 surveillance signal output (Switch 2)
The EV-200 board continuously transmits a 1 kHz sine wave signal to the VX-2000 System Manager
when the EV-200 Board is not reproducing audio signals. The VX-2000 detects the existence of the 1
kHz signal. When the 1 kHz signal does not exist with the EV-200 not in use, the VX-2000 judges the
board's failure and causes the FAULT indicator to light.
Step 2. Remove both the top and front panels.
