1.1 INTRODUCTION
The Multitone RPR 583 pager is a UHF receiver for On-site applications. The pager
receives alpha-numeric messages sent in Multitone Mk7 digital format.
The front panel of the unit has a Liquid Crystal Display (LCD) to display messages
and other information. The unit has a choice of fonts for the LCD which the operator
can select. The three buttons on the front panel are used to control the functions
of the unit.
If the unit receives a message which has more characters than the display can show,
the excess characters are stored. The front panel buttons are used to transfer the
stored part of the message to the screen as required.
Message alert is provided by an audible beep tone and/or by the unit vibrating. The
front panel buttons are used to select the preferred alert (where this option has been
enabled).
Power for the unit is supplied by a single AAA battery. The unit has the facility to be
used with an ‘absence/charging’ rack. The external contacts provide the interface
for charging the rechargeable battery (where fitted) and for the exchange of data
between the unit and the base station. A door on the rear of the unit gives access
to the battery compartment.
A back-up supply for the unit is available when the battery is changed. The back-up
supply is provided by a large-value capacitor, mounted on the decoder board in the
unit. The capacitor, when fully charged, can maintain data in the unit for more than
5 minutes.
The unit case is a 2-piece plastic moulding secured by two cross-head screws. A
lanyard is supplied with the unit which can be fastened to the case and the attached
clip used to secure the unit to a suitable object e.g. belt, or the holster also supplied.
