8.2.2 Entering the MNP for Remote Control Head Operations
The Message Number Period (MNP) is used in an ASTRO ® 25 system to provide additional security in the remote
rekeying of subscriber units. The MNP number may range from 0 through 65535, and serves as an offset value
used in synchronizing remote rekeying transmissions.
When and where to use:
Use these steps to enter the MNP.
Entering an MNP value of 0 or 65535 disables Message Number checking and weakens your system's
security. Consult with your Security Officer to obtain the recommended value.
