Field Use of the DSS-900-KT

DSS-900-KT Digital Spread Spectrum Surveillance System 15

6. If the TX has not yet been deployed, check its channel number and

switch CHANNEL SELECT on the RX to that number.

• If the TX is already harnessed to the agent, move the CHANNEL

SELECT switch until you see the TX LOCK light turn on. This

indicates that the agent has activated the TX and you are

receiving audio.

7. Adjust the VOLUME control, which affects the speaker and the

headsets only. It does not affect the recording.

8. Set the recorder to AUTO unless you specifically do not want

automatic on/off of the tape.

• The POWER ON LED in the RECORDER SECTION will light up when

the squelch level is exceeded by the audio, or whenever you

switch to MANUAL.

9. In the RANGE section, switch MODE SELECT to the alarm output you

want. Refer back to Range on page10 to remind yourself what this

switch does.

10. Verify that TX LOCK is illuminated on the RECEIVER section of the RX.

If this LED is not on, take the following steps.

• Make sure you are using fresh batteries in the TX.

• Make sure that TX and RX are on the same channel.

• Close range to the agent.

• Reorient the RX patch antenna so it is directed more accurately

toward the agent. This antenna has a 60

beam width, so if the

agent is outside that cone, you are losing a great deal of the

available signal.

• Double-check that the RX is turned on, system voltage is in the

acceptable range, and that all connections are secure.
