ABSTRACT:
A portable timing and alarm apparatus for alerting a child that a pre-set interval of time for playing or for observing a pre-arranged response has expired. An audible alarm signals the wearer of the apparatus that the time interval has expired. The length of the time interval is adjustable by use of a key to prevent tampering by the child. In one embodiment, the key is engaged by inserting the apparatus into a module which simultaneously allows two spaced enabling pins to engage mating switches on the apparatus that, when triggered, allow time setting adjustment thereof.
