Frequency
The receiver can be configured to recognize
nine transmitter frequencies: 400 Hz, 512 Hz,
560 Hz, 815 Hz, 1 kHz, 8 kHz, 29 kHz, 80

IMPORTANT: 400 Hz, 560 Hz, and 815 Hz
cannot be transmitted by the 950T or 970T.
Selected frequency is displayed in the lower right corner of the
display.
Antenna
The receiver has four antenna modes described below. The
selected antenna mode is indicated by an arrow on the left side of
the display.
Single
Use in congested areas and to locate deeper
lines. Signal strength peaks when receiver is
over the line being located. Is less precise
than other modes.
