VHF receiver HF section
-
LBB 6012/xx
UHF receiver HF section
-
LBB 6113/xx
VHF talk-back transmitter HF section
-
LBB 6013/xx
UHF talk-back transmitter HF section
MOUNTING
For mounting the receiver and transmitter refer to sec-
tion ‘MOUNTING’ (page 3 and 4).
BATTERIES
The transceivers are powered by three LR1 type batteries
(rechargeable or disposable). To locate batteries, unscrew the
cover screw from the battery compartment (13). When replac-
ing batteries ensure the correct polarity. Recommended bat-
tery types:
LBB 5312/00 Philips LR1 size (alkaline)
LBB 5931/02 Philips LR1 size (re-chargeable)
CAUTION: NEVER LEAVE DEAD BATTERIES IN THE
TRANSCEIVER.
An automatic battery saving function is incorporated in the
transceiver. Should the voltage drop below an acceptable level,
a bleep-tone is emitted until the <Reset> key (4) is pressed.
In systems, with an alphadesk (PC fitted with LBB 6000 card)
the low voltage state of the transceiver is sent to the
alphadesk. If acknowledged, the transceiver will remain in oper-
ation for a maximum period of one hour. If the batteries are
not charged or changed the transceiver will switch off automat-
ically after this period. Before switching off a high volume
bleep signal is given. If not acknowledged by the alphadesk, i.e
the transceiver is taken outside the range of the system, the
transceiver switches off instantly, accompanied by a high vol-
ume bleep.
In a system without an alphadesk, the low battery state of the
transceiver is indicated by a short bleep emitted every two
minutes for a period of up to 1-hour. If no action is taken to
charge or change the batteries during this period, the trans-
ceiver will switch off automatically followed by a high volume
bleep signal.
SWITCHING ON AND OFF
To switch the transceiver ON press the <Menu> key (8) fol-
lowed by the <Enter> key (15). A short bleep signal is emitted.
If the <Enter> key is not pressed within 5 seconds the trans-
ceiver automatically switches off. If no communication protocol
(handshake) exists between the transceiver and the alphadesk,
after a period of approximately 20 seconds, the transceiver will
emit a bleep signal until. After placing the transceiver back into
its storage rack, the transceiver will revert to its previous sta-
tus.
To switch the transceiver OFF, press the <Menu> key (8) fol-
lowed by the <Enter> key. A high volume bleep signal is emit-
ted before switching OFF.
When the transceiver has been programmed for ‘Old system
mode’, the function of switching on and off is done without
endeavouring to contact the paging central (i.e no handshake
required).
Once the transceivers have been switched on, the transceivers
checks if the opcode setting corresponds with the hardware
configuration. If not, a bleep until reset signal is generated.
Note: The ‘switch-off’ function can be disabled by the installer.
TRANSCEIVER ADDRESSES
For Transceiver addresses see Chapter 2.5 Transceiver
addresses.
BLEEP PATTERNS
For Bleep patterns see Chapter 2.6 Bleep patterns. To
programmed personal bleep patterns see Chapter 2.7.
OPCODES
For a description of OPCODES 1 to 6, see Chapter 3.3.
NOTE: Not all opcodes are applicable for transceiver
versions without display. The following opcodes are
therefore not applicable:
OPCODE 4: values Q,S,T,U
OPCODE 5: values P,Q,R,S,T,U.
