DSC 1616, DSC 1832 and the DSC 1864 all come with the same default factory master codes and installer codes. If you just bought or defaulted your PowerSeries panel, the codes will be at these defaults. If you are taking a system over, there is a high probability that the codes will be changed. How do I default the DSC 1616, 1832, or 1864 panel if I don’t have the installer code? Code, forgotten what they changed it to, or are trying to takeover a panel that was installed by an alarm company that changed the installer code. The Master Code is used to make programming changes to your system, as well as arming and disarming your system.

For some time now the resetting of the maritime mobile service identity (MMSI) in a digital selective calling (DSC) radio by the end-user of the radio has been more or less impossible, and to perform a reset of a DSC radio's MMSI the owner typically had to ship the radio back to the manufacturer for him to perform the reset. This situation appears to have recently changed.
There is at least one manufacturer (Standard-Horizon) and one radio model (HX870 handheld DSC radio) in which the end user can perform the MMSI reset himself, with the 'advice of the manufacturer' as is specified in FCC regulations adopted from ITU recommendations. This option appears to have been enabled by three elements:
--the radio has a user-interface with a graphical display which can inform the user of certain embedded parameters

--the radio has a user-interface that allows entry of text and numerical data by the user into the radio
--the radio contains some sort of processor and firmware to operate on coded keys that are unique to its embedded hardware identity
In the specific instance of the Standard-Horizon HX870 DSC handheld radio, the MMSI reset process works as follows:
--the radio must have a recent version of firmware; firmware version v2.03 or higher will allow the user to perform the rest of the procedure
--the user extracts from the radio's user interface a value for a key called the USER MMSI RESET CODE
--the user sends an email to the manufacturer's technical support with the following information: user's full name; radio serial number; present MMSI; new MMSI to be installed; and USER MMSI RESET CODE
--the manufacturer replies by providing the user with a PASSWORD key
--using the supplied PASSWORD key, the user can then change the MMSI to the new value
If the HX870 radio firmware is not at the required revision level, the user can obtain newer firmware from a link:

While the procedure described above is specific to one manufacturer and one particular model, it is hoped that more manufacturers will adopt similar procedures for more DSC radios, permitting the end user of the radio to perform an MMSI reset procedure 'with advice from the manufacturer' and without resorting to physically sending the radio to the manufacturer.
