i have a nam 4.0 when i clear messages light on several sets flashes constantly cant stop it unless i unplug sets and i have an alarm 462 not on the list

Are you sure there aren't other messages from phones not from the NAM? How are you clearing the light?

Try Feature#65.

462 / Problems for network or remote users
Modular ICS 4.0 Installer Guide P0881590 Issue 02
Solution
1. Check that the system hardware is receiving signals
properly.
2. Verify that the switch is sending the correct number of
digits for the Received number length defined in your
system.
3. If the switch at the far end is sending pulse signals, make
sure they are being sent at the proper rate. (Pulse digits
must be 300 ms or more apart for Norstar to receive them.)
Possible problem
If remote callers are having difficulty getting through from the
public network, there may be a problem with your DID Trunk
Cartridge.
Solution
1. Connect a single-line DTMF telephone to a DID trunk
input on the DID Trunk Cartridge.
2. Use the single-line telephone to enter a Received number
that has been programmed for a target line in your system.
Listen for ringback.
3. If you do not hear ringback, check that the target line is
assigned to a telephone and that there is a prime telephone
assigned for the DID trunk.
4. If you now hear ringback, but you also hear the noise of
your unanswered call ringing, check the
cross-connections. If all the cross-connections are correct
replace the Trunk Cartridge.
Possible problem
If remote callers are having difficulty getting through from the
private network, there may be a problem with your E&M/
DISA Trunk Cartridge.
