3.5 - Delays
Except as noted in Rule 3.5 (b), the referee may call a technical foul for delays exceeding 10 seconds.
(a) The 10-second rule applies to the
server and receiver simultaneously. Concurrently, they are allowed up
to 10 seconds after the score is called to serve or be ready to
receive. It is the server's responsibility to look and be certain the
receiver is ready. If a receiver is not ready, they must signal by
raising the racquet above the head or completely turning the back to
the server. (These are the only two acceptable signals.)
(b) Serving while the receiving player/team is signaling “not ready” is a fault serve.
(c) After the score is called, if the
server looks at the receiver and the receiver is not signaling “not
ready”, the server may then serve. If the receiver attempts to signal
“not ready” after that point, the signal shall not be acknowledged and
the serve becomes legal.
