are shielded using sheet metal cans to prevent internal and external electromagnetic interference from degrading
the module’s performance and to prevent the module from interfering with other nearby devices. The module is
plugged into the fixed mating connector and secured with 4 screws to the standoff posts.
The module has no keypad, display, microphone, speaker or battery. The physical dimensions of the DM-15/25
