With a height of 12.7 cm, width of 6.1 cm, depth of 4.2 cm (with standard size battery), and weighing just 240 g, the Motorola R2 is a full-sized commercial two-way radio that is lightweight and fits comfortably in the user's hand. The R2 can also be attached to a belt using either a belt clip or a carrying case.
The R2 features programmable buttons that allow instant access to frequently used features. A common use for one of these buttons is an emergency function that will alert all other radios within range that there may be a security breach.
