This was an official notice sent out by Quay Pacific by email. The full text is below.
Dear Owners & Tenants,
The enterphone to each building has been replaced.
Your new buzzer code is the same 4 digits of your unit number.
If your enterphone buzzer does not work, you must email the Caretaker copperstonecaretaker@gmail.com and provide the following information:
Your Unit #:
Name to be displayed on the Enterphone:
Phone number that will connect to Enterphone:
Please note that long distance numbers will not be accepted.
As I mentioned before, the key to buzz the door open is now the asterisk (*), not the zero key (0) or 9 key.
