The TR-7 module is digital recorder/player for voice, music or sounds with the possibility to store a maximum of 120sec.
It allows sharing total timein different combinations onmessages with different number and timing.
It includes power stage, volume control, indicators Leds, and connection terminals.

POWER SUPPLY and INSTALLATION.
POWER SUPPLY.
The TR-7 circuit had to be supplied by a 12 VDC power supply correctly filtered. We recommend you
to use the FE-4 power supply which has been developed to perfectly answer to the circuit needs. Install a fuse anda
switch has it is indicated onthe schedule. Both are necessary for the module's protection as well as for your own
safety, as it is required by the "CE" regulations. Connect the positive and the negative of the power supply to the
respective positive and negative terminals of the module, indicated in the wiring map. The distance between the
power supply and the module has to be as short as possible (max. 60 cm). Verify thatthe assembly is correct.
Note.
Connections indicated as 230 VAC in t
he wiring map
countries. Cebek's Modules and/or transformers will besupplied with corresponding modifications for their
connectioninthesecountries.
INSTALLATION.
See the General Wiring Map. Install a fuse at the terminal indicated as Play/Rec. Connect also a push
button to each message input. If you have configured the module with a number of message inferior than 15,
messages input no used, could be left without connection.
Finally, you have to connect a loudspeaker to the corresponding output. This have to be a quality loudspeaker and
with a minimum power of 10 W.
For Messages and Play/Recinputs connections, the maximum suggested cable length is 20 cm. If you need more
than this length, you haveto use shielded cable and connect its braidtothe"Common"terminal. Nevertheless, even
using shielded cable, the maximum length had to be inferior than 80 cm. If you don'trespect this point, probably the
module doesn't properly work.
The rest of connections (power supply and loudspeaker), could be done with standard parallel cable.
For Messages and Play/Recinputs connections you have to use devices free of power like push buttons, switches or
relay. More over, we strongly suggest you to use quality components.
For the installation, you have to use a metallic enclosureand connect the circuit's negative terminal to it. Don't
remove or manipulate anycomponents of the circuit, otherwise, you could damage the module and the warrantywill
be cancelled.
TO SELECT THE NUMBER OF MESSAGES.
TO CONFIGURE the TIMING and NUMBER of MESSAGES. The TR-7 offers a total recording and playing time of
120 seconds, which will be allowed according to the number of messages that you configure the module. To select
the number of messages as well as its timing, you haveto select among any of the 16possibilities indicated on the
fig. 1., placing switches 1, 2, 3 and 4 of the "Control" dipin ON or OFF position, according to your needs.
Note that all combinationsof the Fig. 1 are based on a total time of 60 sec. Thanks tothe switch Nº5, you could
double this time till 120 sec. If you place the switch Nº5in ON position, each of the 16 possible messages
configuration will double the assigned time. If you place the switch Nº5 in OFF position, the messages configuration
will be maintained according to the mentioned Fig.
Before to activate the TR-7module, youhave to select a position (ON or OFF) for the switch Nº5. Otherwise, if you
change its position after recording several messages, their register will be damaged orerased.
For the moment forget therest of switches, their function will be explain further.

OPERATING MODE.
INDICATORS.
There are five indicators Leds on the circuit.
- POWER Led. To indicate that the module is supplied.
- RUN Led. It intermittentlylight during a message recording or playing.
- REPEAT Led. To indicate that the Repeat function is activated.
- REC Led. To indicate thatthe Record mode is activated.
- PLAY Led. To indicate the PLAY mode is activated.
PROTECTION AGAINST THE INVOLUNTARY RECORDING.
The TR-7 module includes a protection against involuntary recording. If you place theswitch Nº8 in ON position, the
module will accept the recording. If you place it in OFF position, the TR-7 doesn't allowtorecordany message.
AUTOMATIC GAIN CONTROL, AGC.
The automatic gain control allows correcting, the recording volume level
regarding the distance between it and the microphone (between maximum and minimum levels accepted by the
circuit). If you wish to activate the AGC, place the AM
jumper in ON position . If you don't wish to activate
this function, maintain the jumper in OFF position.
Do never close or place the AM jumper in ON and OFF
inputs at the same time and select obligatory one of
these options. Otherwise,the module doesn't properly
work
REC RECORDING.
Once the number of message
selected, the recording willbe done independently for
each one and during the assigned time. To record, and only during this operation, remember that the switch Nº8 had
to be in ON position. When this operation is done, you have to place it again in the OF position.

OPERATING MODE.
Activate the Recording function closing the Play/Recswitch. This operation will beconfirmed when the Rec Led lights.
Then, select which of fifteen messages you wish to record and close corresponding push button's contact. The
recording mode will beactivated during its assigned time. The Run Led will cyclically light till the end of the recording.
You couldn't stop the recording before the end of the message's assigned time.
recording mode will beactivated during its assigned time. The Run Led will cyclically light till the end of the recording.
You couldn't stop the recording before the end of themessage's assigned time.
When you will activate the recording mode, you have to clearly and highly speak in front of the microphone and a t a
maximum distance of 20 cm. Otherwise, and because of the analogue-digital integrated circuit's conversion, the
generated noise by it will be audible in your own recording.
PLAYING.
Before to activate a normal or repetitive function, verify that the switchNº8 is OFF position.
Place the Play/Rec switch in open position, the Play Led will light. Then, select which message you wish to record and
close corresponding push button's contact, the messages will be played. The Run Led intermittently light duringthe
playing. If you press at the same time several messages, the module will play the first one pressed.
The module doesn't allow activating a message if other one is playing, you have to wait the end of the played one.
To adjust the volume level, you have to use the potentiometer indicated on the General Wiring Map. Do never place
the potentiometer at the maximum, otherwise you will saturate the output and sound distortioned.
REPETITIVE PLAYING.
them, you have to place the switch Nº7 in the wished place. For a normal playing, place it in O N position and for
repetitive playing placeit in OFF position.
If you select the repetitive option, at the end of the selected message time, and not before (even if the messageis
shorter than the assigned time), the module will automatically start again this message. This cycle will be repeated
indefinitely if the push button corresponding to thismessage is closed. When you release it, at the end of the
message, the TR-7 module will stop the cycle and goback at this quiescent state.
