2.7 CONFIGURING THE MX20 & MX20 I/O
1. Turn on power to the MX20.
2. Immediately after the self-test is complete, press line select keys 1, 4, and 6 in sequence before
pressing any other keys (where 1 is the top line select key, 4 is the fourth key down, and 6 is the lower
most line select key). If other keys are pressed before or during this sequence, the MX20 will be in the
normal operational mode. To enter the install mode, turn off the MX20 and start again at step 1.
3. Press the function key until the INSTL function is present. If INSTL function is not found, restart the
unit. Carefully press line select keys 1, 4, and 6 in sequence. Do not press any other buttons before
pressing the 1, 4, 6 line select key sequence.
4. Select the INSTL function by pressing the smart key directly below the INSTL label. The
Enable/Disable Functions will be the first screen to appear.
NOTE
MX20 power must be cycled before configuration changes will take affect.
After a configuration change, a message will appear on the screen telling you to wait 30 seconds
before turning off power. You may continue to make configuration changes without pausing;
however, do not turn off power to the MX20 until waiting 30 seconds after the last configuration/
setting change. The message will disappear when it is safe to cycle power.
