What is the audible beep sequence for byo-yomi? for example does it beep with 10 and 5 seconds left?

In the 10 seconds is the first beep and then in 5 seconds it starts beeping each second until finishing

Are the number of remaining byo-yomi periods displayed on the clock when playing? (without having to press a button to temporarily see)

No, you cannot see the number of remaining periods.

How do I contact you to get a copy of the manual? Thanks.

Dear customer, Pelase send us a message though Amazon. File could only sent by message

Is this capable of disproportionate time / handicaps?

Dear Customer, Yes, this clock could let you set different time for 2 players. But if you need more complicated functions,please choose the gray one (PQ9921)!
