Personal Security Data Book |15
A call to a receiver from an alpha desk, is recognised by
the receiver’s software.This software enables speech, if
required,to be included in a call complete with a pre-
programmed speech time.
Decimal group call
The receiver can be allocated a decimal group address
where it can be paged with other receivers within a group.
A decimal group call is transmitted when the address
contains a letter F in any of the displayed 3 least
significant digits on the receiver’s display. For example
xxxF,xxFx, or xFxx.Decimal group calls can be disabled
by a solder link located on the recivers printed circuit
board.
Programming
Programming the addresses of the receivers is done via
wireless transmission from the system encoder and
transmitter to the receiver, or via encoder only, with the
receiver stored in a storage rack. The receiver must be set
in the programming mode by means of a slide switch
located behind the receiver’s battery compartment.
Programming should be carried out by the installer or
system manager who allocates the call numbers of the
receivers. The information programmed in the receiver is
safeguarded by an E-EPROM, making it non-erasable by
its user.
Battery saving circuit
The battery economizer system is system specific and is
based on the 5F5F pre-amble string. Because it is system
specific it cannot be interfered with or upset by
neigbouring radio equipment or other paging systems.
The battery economizer can be enabled by a solder link
on the receivers printed circuit board.
Batteries
Two LR1 size batteries are used. Low battery voltage is
indicated by a short bleep every 17 seconds.
External contacts
Three contacts are provided on the receiver for charging
purposes and absence indication when stored in a storage
rack.
Compatibility
The receivers are fully compatible with the standard
DP6000 system, also in combination with other types of
DP 6000 paging receivers without any adaption.
