Section Length Frequency Note
4-10 kFt 335 Hz Additional fault isolation is
recommended if the section is
greater than 10 kFt. Set the
FREQ to
335 Hz If the section is longer than
10 kFt,
7.2 AUTO-SET
The preferred and easiest way to start the ST-101 is using the F3 AUTO-SET from the Main screen. The ST-
101 will scan the connection and set the initial frequency and PWR LEVEL. The frequency and PWR LEVEL
can then be adjusted if desired.
1. From the Main screen, press F3 AUTO-SET .
2. The ST-101 prompts to connect the output.
3. Connect the clips as described in 6.4 above and press F1 START .
The ST-101 determines the initial frequency and PWR LEVEL for the current connection.
4. The ST- 101 displays, “Set SR - 101 Freq XXX”. This is the initial frequency as determin ed by the ST-
101. Set the SR-101, or other receiver, to this frequency and press F1 OK .
5. The ST-101 starts transmitting the signal at the frequency and power level determined by the
scan. Follow the instructions for the receiver to ensure the signal is detected by monitoring the
cable.
6. The frequency can be changed by pressing the FREQ key or the power level by pressing the LEVEL
key as needed. Always ensure the ST-101 and receiver are using the same frequency.
7. Press F1 STOP to temporarily stop transmitting but remain in the Transmit mode. Pressing F1
START from the stop screen will resume transmitting.
8. Press CLR to stop transmitting and return to the main screen.

Use these instructions to transmit a signal at a pre-set frequency.
1. From the Main screen, press FREQ . If the desired frequency is displayed on the main screen, this
step may be skipped.
a. Use F1 , F2 , and F3 to select and set the desired frequency.
2. Press F1 START
3. The ST-101 prompts to connect the output and press F1 START.
The ST-101 uses the selected frequency and gradually increases the power level to obtain a
recommended initial
PWR LEVEL . This level should be sufficient in most cases. The frequency and
gain on the receiver must be adjusted using directions provided with the receiver.
The power LEVEL can be adjusted by the user by pressing the LEVEL key from the Transmit screen.
The level may be adjusted up or down, as needed, within the range of 1 to 10.
NOTE: The ST-101 will not transmit signals at power LEVELs that may damage internal circuits.
