1. Attach your SMB to BNC cable to TP1 on the TR4090 board.

2. Set your scope to 100 mV vertical, 1 ms horizontal.

3. The noise floor will typically be between 50 to 100 mVpp in a “clean” environment.

4. The tag signal should always be at least twice the amplitude of the noise.

5. See section 8 of this document for how the tag signature should look.

7.0 SERVICE

7.1 MAINTENANCE

No routine maintenance is necessary on this system though the system should be tested

periodically to ensure it is in safe working condition and that performance requirements

are satisfactory.

7.2

TROUBLESHOOTING

System does not work:

Check the fuse on the TR4090 indie the TPRO7100 or TPRO7200 and try again

No field is being generated:

Verify that the TR4090 is getting 12 volts

3. No baseband signals are visible at TP1 on the TR4090:

Replace the TR4090 board

4. Noise Level:

In a location with high levels of noise, always try to remoce the source of the noise first.

For instance, if the noise-source is a cash register near the system, position the cash

5. Fuse on TR4090 keeps blowing:

Replace with a fuse fo same type and rating. If it blows again, try to fault-find the

problem. If you can’t solve the problem, then replace the board at fault.

Poor detection:

Make sure the antenna is tuned (see section 12)
