Time-in:
After time has out the game watch or clock shall be started when
the Official signals time-in. If this follows

a) a free throw for a double foul, the Official signals time-
in by blowing his whistle as the ball leaves his hands on the
toss at center,

b) a free throw for any other foul, the Official signals
time-in by a chopping motion of his hand after the last free throw,
including any substitute free throw, this signal being given (1)
as soon as it is evident that the ball will go into play by a re-
bound, or (2) if the throw is successful, or is for a technical
foul, or if the ball is awarded out of bounds for any other reason,
as soon as the ball crosses the boundary line when it is thrown
into play;

c) a period when time has been out for any other reason.

Signals:

a) For any foul the Official raises his arm (or arms) above
his head,

b) When a substitution is to be made, the Official motions
for the substitute to come on the floor.

c) When there is to be a charged time-out or an Officials'
time-out for a technical foul or any other stoppage, the Official
will hold the palms of his hands (with both arms crossing over-
head) toward the Timer.

After completion of time-out, start the watch or clock on signal
from an Official. He will signal for time-in by a chopping motion
of the hand or with the whistle.

Watch for the signal at the following times:

a) When play is resumed by a throw-in from out of bounds the
signal will be given when the ball crosses the plane of the bound-
ary line.

b) When the ball is to be in play following a missed free
throw the signal will be given as soon as it is evident that the
throw is not successful. This occurs after a single free throw for
a personal foul and after the last throw of a multiple throw if
at least one throw is for a personal foul.

c) If play is to be resumed by a jump the whistle is the sig-
nal to start the watch or clock and it will be sounded as the ball
leaves the official's hands for the toss. Note that play is re-
sumed by a jump at center after a double foul or fouls by both
teams which are administered the same as a double foul.

Procedure at End of Period:
Fire pistol at end of period.

If you are unable to make the Official hear the signal, go
on the floor immediately to notify him. You are responsible for
deciding whether the ball was in the air on a try at the instant
time was up in case the signal did not sound or was not heard by

the Official.
