To set the neon voltage ring ping:

1. Call a telephone with a neon message indicator and leave a message.

2. Check for “ring ping” (single ring pulse) each time the lamp flashes (approximately every 3 

seconds).

3. Adjust the control clockwise in small increments until the ring ping stops. Be sure that the 

message lamp still lights when the adjustment is finished.

To complete the installation:

1. Type logoff and press Enter to prevent unauthorized changes to data. 

2. Set the left and right doors onto the hinge pins and close the doors. The doors must be 

closed to prevent EMI emissions. Tighten the door screws. 

3. Set the right cover panel onto the right panel and secure. Do not use force.
