The audio relay board contains three specially treated DPDT relays. Kl , K2, and K3 may each have their contacts
supervised (as they usually are). Supervising these contacts means sacraficing monitor points 6, 7, and 8. Refer
to Table P to determine jumper placement.
Note:
If any of the relays is unsupervised and the corresponding monitor point (6, 7, or 8) is to be used for
another purpose, remove the following resistors on the relay board:
R37 for monitor point 6
R36 for monitor point 7
R35 for monitor point 8
