Motorola has issued an Intent to Cancel Notice for the CP Series RSMs: MDPMMN4013 and MDPMMN4029. The cancellation is effective on 12th September. However, the MDPMMN4013 has already sold out and can no longer be ordered. Newer, replacement RSMs are available: PMMN4013 and PMMN4029.
Please view the Intent to Cancel Notice for full details.
The replacement parts are technically the same, have the same pricing and are still common for the CP and DP1000 Series radios. They have the Digital symbol on the connectors.
