The CV-150 vibrating pager is used in places that need queue management systems to systematize servicing and prevent chaos and crowding. This model is among the most useful vibrating pagers in fast food bars, food courts and restaurants. For letting the customers know that their orders are ready, the pager number is entered into a transmitter, which then informs the customers through activating vibrating, sound and light alerts on their pagers. Model CV-150 can be used in quiet environments as well as crowded and noisy places, where regular audio calling systems cannot function desirably.
