ReFLEX is a wireless protocol developed by Motorola which is used for two-way paging. It is based on the one-way FLEX protocol and comes in two variants, ReFLEX25 and ReFLEX50. Later version 2.7 of the ReFLEX protocol was released. Devices compliant with ReFLEX 2.7.x can operate on both ReFLEX25 and ReFLEX50 networks.

A reflex action is an automatic (involuntary) neuromuscular action elicited by a defined stimulus. In most contexts, especially involving humans, a reflex action is mediated via the reflex arc (although this is not always true in other animals, or in more casual usage of the term 'reflex'.)
