Two-tone sequential, also known as 1+1, is a selective calling method originally used in one-way, tone-and-voice paging receivers. Many companies have their own names for two-tone sequential options. General Electric Mobile Radio called it Type 99. Motorola called it Quik-Call II.
Pb II tone & voice radio for 2-tone signalling systems 68–88 MHz / 146–174 MHz (US). Pb II A04FNC Series radio pager 450–512 MHz (Eur). Pb II MAA04FNC1568AA 440–470 MHz für Funftonfolge-Rufsysteme (Eur).
The Motorola Pageboy used to be very popular with fire brigades as an alarm receiver and, thanks largely to the success of this initial venture, pagers quickly began to replace public announcement systems in hospital and factories. The pager was activated by a 2-tone code, after which a voice message was transmitted.
Pager. A pager, also known as a beeper or bleeper, [1] is a wireless telecommunications device that receives and displays alphanumeric or voice messages. One-way pagers can only receive messages, while response pagers and two-way pagers can also acknowledge, reply to, and originate messages using an internal transmitter. [2]
Indian Creek Fire Department (Fayetteville, IN) paging tones activating Motorola Minitor pager. Minitor pagers, depending on the model and application, can operate in the VHF Low Band, VHF High Band, and UHF frequency ranges. They are alerted by using two-tone sequential Selective calling, generally following the Motorola Quick Call II standard ...
Motorola reused the name for at least one previous product. [11] [12] [13] It is also a UHF tone and vibrate paging receiver produced in the mid-1980s that responded to two-tone sequential encoding, including GE type 99, Quick Call II & 1+1, REACH* and 5-Tone Sequential.

Its usual designation is an acronym of the P ost O ffice C ode S tandardisation A dvisory G roup, the name of the group that developed the code under the ...
Motorola PageWriter 2000. The Motorola PageWriter 2000 was a two-way pager introduced in 1998. [1] Featuring the 68000 based Motorola DragonBall processor, 1 MB of internal storage, a four color grayscale screen, IrDA transmitter/receiver, and a full QWERTY keyboard the PageWriter represented a combination of both PDA and pager in one package.
FLEX is a communications protocol developed by Motorola and used in many pagers. FLEX provides one-way communication only (from the provider to the pager device), but a related protocol called ReFLEX provides two-way messaging.
Motorola Type II. Motorola Type II refers to the second generation Motorola trunked radio systems that replaced fleets and subfleets with the concept of talkgroups and individual radio IDs. [1] [2] There are no dependencies on fleetmaps, therefore there are no limitations on how many radio IDs can participate on a talkgroup.
