Using the Enclosure Security Bypass
The FMPS provides a security bypass, allowing a technician to access a locked FMPS enclosure. Using a 0.540
Can Wrench (available through Harris Communications Products Division, Camarillo, CA, 800 437 2266, P/N
44007-000), loosen the security nut located on the bottom of the enclosure and slide the security hasp out of the
enclosure. Replace in reverse order.
