1. Introduction
The Multitone RPR 750 Series is a "top-fired" alphanumeric radio-paging receiver,
designed to operate in the 25 - 54MHz (751), 138 - 174MHz (752) and 407 - 470MHz
(753) radio frequency bands.
The paging and messaging data is transmitted, using either of the Multitone proprietary
MK6 and MK7 digital code formats, or the CCIR Radio Paging Code No.1 (POCSAG)
format. The Multitone formats also have the facility for enabling speech messages,
following initial paging data.
User alert facilities include selectable options of beep-alert tones, flashing LED, speech
and/or vibration. Any of these alert options may be accompanied by an alphanumeric
message, either pre-formatted up to 60 characters in length (Multitone MK6), or free-
formatted up to 120 characters (Multitone MK7 and POCSAG).
For use in areas of classified hazardous atmospheres, the RPR 750 is also available in
"intrinsically safe" variants, which are certified to recognised international standards.
The equipment is powered from a single "AA" (LR6) size battery, or a "AAA" (LR03) for
the IS variant. This may be a disposable primary cell, or where the system is suitably
equipped, absence/charging racks enable the use of secondary re-chargeable cells.
During periods of battery replacement, or the pager being switched off, an internal back-
up storage device will enable the retention of data for up to 12 hours.
For the intrinsically safe equipment variants, only certain battery types are
permitted. Refer to user information for correct types, before attempting to replace
these items.
1.1 Equipment Features
