The Comelit 2708W doorbell may be barely audible even when the volume is set to high due to the system expansion. According to the manual, if the maximum number of 100 internal units is connected, the audio sound level is reduced to 74 dB(A). If fewer units are connected (e.g., 75 units), the sound level increases to 77 dB(A). If the system has a high number of internal units, the reduced sound level could make the doorbell seem quieter. Additionally, the handset has a three-position selector for call volume adjustment, so ensuring it is set correctly is important.
