6 Using SiS Mode Accessories
Method:
1. Apply the signal using the direct connection method. Remember to isolate the cable beforehand as below. It is also
preferable to use the ground stake as an independent ground. Using the station ground may result in multiple signals as the
signal will return along commonly bonded cables.
2. Select an SIS signal from the transmitter (there are many available but lower frequencies will create less bleed off to other
lines, 491Hz is a good frequency to start with).
3. Connect the remote antenna accessory to the locator and place it on the red lead of the transmitter with the arrow on the
remote antenna pointing away from the transmitter. Select the frequency using the “f” button so that it matches the selection
on the transmitter. The screen should look similar to the below picture.
52.1
SiS8440
25dB
4. If necessary, adjust the sensitivity so that the bar graph is on scale. Note that the front half of the circle is red indicating
slight signal distortion, and the polarity sign is “+”. This indicates that the signal is flowing forwards.
5. If the “-” polarity is indicated as below, it will be necessary to perform an SIS reset before proceeding.

6. However, if in doubt always perform the reset to be sure the antenna and receiver are synchronised.
Performing a remote antenna SIS reset
As previously described, connect the transmitter to the service to be identified, place the antenna on the red cable as previously
described. Press the “i” button. The screen will change to something similar to the below.
