Why is there feedback when pressing the talk button on my Aiphone LEM-1DL Intercom System?
If you experience feedback when pressing the talk button in a dual master Aiphone Intercom System, it might be because one power supply is used for both masters. Ensure that each master has its own power supply, using any power supply with output between 12-16V AC or 12-24V DC. Aiphone recommends the PT-1210N.
What to do if Aiphone LEM-1DL has no call tone, no communication, and chirps when volume is high?
If you're not getting a call tone or communication and hear a chirping sound when the volume is turned up on your Aiphone Intercom System, the voltage on the LEM-1DL might be incorrect. Check the power supply. If it's model SKK-620, replace it with model PT-1210N. Verify that the voltage on the +/- terminals of the LEM-1DL is between 12-16V AC or 12-24V DC.
Why is call tone heard at second master when pushing talk switch on Aiphone LEM-1DL?
