4.2.4.2"Select/Set" Button
The "Select/Set" button on the front panel of the OSM/ESM has the following functions:
•Pressing the button briefly moves on the display of the port LEDs (display mode). The current display mode is indicated by the display mode LEDs.
•If the display is in the port status (all display mode LEDs off) and if the button is pressed for three seconds, the display mode LEDs begin to flash. If you then continue to press the button for a further two seconds, the OSM/ESM is reset.
When it is reset, all the settings of the OSM/ESM are set to their defaults (as set in the factory). This allows you to cancel settings made, for example, with
•If the display is in the fault mask status and you press the button for two seconds, the display LEDs start to flash. If you then press the button for a further two seconds, the current status of the ports and the supply voltages are entered in the fault mask. This means, if, for example, the ports 1, 5, 6 had a valid connection (in other words the port status displays of these ports are lit green or yellow) and if power supply 1 was active at the point when the values were entered in the fault mask, ports 1, 5, 6 and power supply 1 will then be monitored.
Note
If the "Select/Set" button is pressed while the device is starting up (takes approximately 20 seconds) after turning on the OSM/ESM, the OSM/ESM changes to the load firmware status (all display mode LEDs flash simultaneously). This status is exited by pressing the button again. For further information on loading the firmware, refer to Chapter 6.
