Important Safety Information
System Plannin
Proper plannin is the cornerstone to an effective warnin system. The Federal
Emer ency Mana ement A ency (FEMA) publishes the “Outdoor Warnin Guide” CPG
1-17, which should be used in plannin your system. In addition, you should reco nize
and understand the followin items:
•Outdoor warnin s sirens and equipment are not intended to be heard indoors.
Conversely indoor devices are not intended to cover outdoor environments. All
devices have specific purposes and distances that they can be considered effective.
Proper placement and selection of the correct equipment is necessary to cover a
desired area. Refer to the FEMA uide for placement uidelines.
•Trainin is necessary to ensure those responsible can correctly activate the system. It
is also necessary that everyone understand the purpose of the warnin system and the
protective actions they need to take when the system is activated. Periodic tests can
serve to accomplish the trainin for the operators, in addition to demonstratin the
various si nals to the public.
•All warnin systems must have contin ency plans in case equipment problems or
operator errors interfere with its performance. Just as with the primary warnin
system, the contin ency plans should be periodically tested to make sure those
responsible know how to implement them and the necessary response from the public
is achieved.

ENC-3300-DTMF
Installation
The ENC-3300 attaches to a customer supplied two-way
radio to generate over-the-air DTMF signals intended to
control remote equipment and pagers.
Audio, PTT and carrier detect lines from the radio are
attached to the ENC-3300 using connector J3.
Access to connector J3, testing and adjustment controls
is performed by removing two screws from the bottom of
the door, then pulling the lower edge of the door forward
and out and setting the access door aside.
Output Connector
Connect the appropriate wires between your radio to the encoder. See the Output Schematic on page
44 or Radio Interface on page 25 for additional information.
The ENC-3300 includes a 9 position depluggable connector for connections to the external radio.
Connectors and cables for specific radios are not included with the encoder.

Power
Attach 11 to 14 volts DC to power connector J7. Connector is 2.1mm x 5.5mm. Center pin positive.
Audio connections to your Radio
It's beyond the scope of this manual to address the programming of individual two-way radio models,
however its generally best to begin with your radio set to transmit flat audio response and to disable
AGC and other settings which may affect the inbound audio from the ENC-3300.
Adjust Audio Levels
After connecting your radio, use a communications service meter and adjust the output deviation on
your radio to the correct level.
1. Press and release SW10 “10 sec Test” to transmit a test tone.
2. Adjust POT1 “TX Audio Level” to the correct level while the radio is transmitting.
Genave/NRC,Inc. 9000-0000-086 rev 4 Pg. 13

ENC-3300-DTMF
Programming
If the encoder is not yet programmed, insert the 2G SD memory card containing
the DTMF settings then reset power to the encoder. The program information will
be transferred to the encoder as it starts.
Open the access door on the ENC-3300 to
insert or remove the memory card.
To insert, slide the card into the card holder
until it latches into place.
To remove, lightly press the memory card
down to release it from the card holder. It will
pop up slightly and can then be removed.
During a program upload the encoder actively
monitors the new data as it arrives and
searches for possible errors or corrupted data. It saves the results of the search in a report file on the
SD card. The report file has the same name as the file just uploaded, but with a suffix of .RPT (Report)
instead of .GP3. To verify the transfer it's recommended this report be examined with a text editor such
as Windows Notepad after an upload.
See Programming via SD Card on page 20 for additional information.
Testing
Reattach the access door. Test the encoder and radio completely before placing into service. Check
the transmitter deviation, signal symmetry, and all codes and actions using a communications service
monitor, oscilloscope and associated test equipment.

ENC-3300-DTMF
Usin the ENC-3300
The encoder should be placed on a flat surface.
Sending a signal or command
• Make sure the encoder is powered and ready. Also make sure the two-way radio is turned on,
working and the correct channel is selected on the radio.
• Firmly press then release the button on the ENC-3300 to initiate the transmission sequence. The
button should be pressed for at least 1/2 second or until the unit beeps. The red “ usy” indicator will
turn on.
• If the button has been programmed to require a second press (Tap-2™) before sending the signal, a
15 second countdown timer will appear and the internal speaker will beep every second. The signal
will not be sent unless the button is pressed again before the timer expires.
• The “Tx” indicator will turn on when the encoder begins generating the DTMF code string.
• The LCD screen will indicate the progress and completion of the action.
• After completion of the transmission, both the usy and Tx indicators will turn off and you are free to
begin another activation. After a short period the encoder returns to its welcome screen if no other
buttons are pressed.
Stopping a transmission in progress
Press and release the ESC button to stop a transmission in progress. This will stop further signals or
actions, however it will not retrieve signals already sent.
Genave/NRC,Inc. 9000-0000-086 rev 4 Pg. 18

ENC-3300-DTMF
ESC Button
The ESC button located on the keyboard has several duties.
1) Press and release while the RXC is running to stop actions including button countdowns,
uncompleted transmissions and other activities.
2) Pressing and holding the ESC button for at least four seconds will result in the RXC prompting you
to release the button to adjust the clock.
3) Press and hold the ESC button for at least eight seconds to perform a reboot that will also
reinitialize the network and SD memory card interface. It has the same effect as removing and
reapplying power.
4) While the ENC-3300 is powering up, press and hold the ESC key. After a few seconds the LCD
screen will display a countdown timer. If the button is still pressed when the timer expires the program
in the ENC-3300 memory will be transferred to the SD memory card. The new file will overwrite any
file on the SD card with the same name.
The download feature can be disabled by using the SYS,PGMLOCK command. See PGMLOCK on
page 35.
No countdown or option to download the program information will occur if PGMLOCK is enabled.
System Clock – Adjustin Time and Date
Press and hold the ESC button for at least four seconds. When you initially press the ESC button the
lcd screen will display “Release ESC button.” After four seconds a countdown timer will begin and the
lcd screen will display “Release ESC now to set clock”. Release the Esc button to enter the clock
adjust mode.
The top line of the lcd screen shows text information describing the values on line 2.
Use keyboard buttons 1 and 2 to move the cursor on line two left and ri ht respectively.
When the cursor is under the digit to be changed, use keyboard buttons 5 and 6 respectively to
increase and decrease the value. Repeatedly pressing the increase value (button 5) will roll the digit
from its maximum value back to zero.
After completing all changes, press keyboard button 8 to save the changes.
The encoder will exit without saving the changes if there have not been any button presses for several
minutes or if the ESC button is pressed.

ENC-3300-DTMF
Pro rammin via SD Card
Programming changes are accomplished using a 2G micro SD memory card with
FAT16 formatting. This method makes field changes fast and easy since no computer
is required on-site. Memory cards can be sent to customers so they can make the
changes themselves.
After making program changes and saving them to the SD card, the card is inserted into the ENC-
3300 and the new settings upload the encoder as the encoder starts. The encoder retains the data in
memory when power is removed so the SD card can be removed after the program upload is
completed.
Active Upload Monitorin – Report File
During a program upload the encoder actively monitors the new data as it arrives and searches for
possible errors or corrupted data. It saves the results of the search to a report file on the SD card. The
report file has the same name as the file just uploaded, but with a suffix of .RPT (Report) instead of
.GP3.
The report is a standard text file and can be viewed with programs such as
•Microsoft: Notepad, Wordpad or Word.
•Multi OS: OpenOffice or LibreOffice.
•Apple: TextEdit.
•Linux/Unix: gedit, vi, nano.
Example - Successful Upload Report
