Operation

6 Operation

Once all installation steps have been completed, you can start operating the Mitsubishi Alarm Modem.

Self-test after power up

The Mitsubishi Alarm Modem carries out an extensive self-test after the power supply is switched on. All the LEDs will switch on for test purposes and all three types of memory are checked. The memory test is also carried out automatically with every power up.

Memory test

This tests the internal memory with RAM, program memory (Flash ROM) and the file system in the user memory (Flash). On basic models (2 MB for the user memory) this test lasts approx. 12 seconds. If memory expansions have been fitted, the time can be considerably longer depend- ing on the size of memory in use.
