LBB 6066/xx
VHF/UHF Talk-back transceiver with personal security
and dial functions
- Similar to LBB 6065/xx but with :
- 12-key dial-pad
This transceiver, in combination with personal security
facilities, provides two-way speech communication
between user and system operator, other users in the
system equipped with talk-back facilities, and access to
the public telephone network.
A 12-key dial-pad allows the user to dial any number
required for contacting other users of the DP 6000
system, or for dialling into the PABX or public telephone
networks should this be connected to the DP 6000 system
The alphanumeric display shows the number being
dialled. Up to 9 dial numbers can be stored in the
transceiver’s memory stack, and recalled for ‘short
dialling’using the <Menu> key and the appropriate
number key on the keypad. A ‘Quick-redial’ facility
enables the last entered dial number to be redialled.
NOTE: For personal security functions and controls and
indicators refer to transceiver version LBB 6065/xx.
General for all version types
Operational characteristics
A paging call is originated from a control desk, or from a
telephone via an appropriate coupler or from another
transceiver in the field. The transceiver is paged with a
pre-programmed bleep signal pattern, from a selection of
14 different bleep signal patterns, 7 with a normal tone,
and 7 with a cricketed tone.
Alternatively the transceiver can also be paged with one
of two bleep patterns personally assigned by its user. The
tones can be programmed to be recognised for a variety
of circumstances or conditions.
In ‘talk-back’versions,on reception of a call, the
transceiver holder simply presses the ‘press-to-talk’
button and speaks into the transceiver’s built-in
microphone to the originator of the paging call. In this
manner a two-way verbal conversation (talk-back) is
established.A talk-through mode can also be selected
allowing two transceiver holders to converse with each
other. If the transceiver is in the storage rack an absent
indication is passed to the caller.
Addresses
The transceiver can have up to 8 different addresses as
follows:
1 x ALL call address
2 x Individual call addresses
5 x Group call addresses
Programming
Initially, the transceiver is programmed by the DP6000
system manager who, amongst other things, determines
the system call codes and the individual and group call
addresses.A switch located in the transceiver’s battery
compartment enables a paging system manager to
program the unit from the DP6000 control desk.This can
be done while the transceiver is housed in its storage rack
or it can be done in a wireless type situation.
The user can also choose a number of pre-selections such
as bleeper on/off, or bleeper loud/soft. The number of
available functions which can be pre-set via the menu is
predetermined by the system manager. The user can also
program nine numbers to serve as quick dial memory
positions.
Power
The transceiver is powered from three LR1 batteries
which can be either disposable or rechargeable.The
transceiver incorporates an automatic battery saving
function. This function responds to a system
programmed message and ensures that the available
power is used efficiently. A battery voltage level checker
monitors the battery voltage and generates a warning
signal should this drop below an acceptable level. If
rechargeable batteries are used, they are recharged when
the transceiver is placed in a storage rack.
