The Main Menu lists all frequencies available for activation. For information on adding additional frequencies to the Main Menu so they can be chosen

for activation, see “Frequency Selection Control” on page 33.

A long press on the Frequency Key will bring up a list of all Checked Active Frequencies. To use one,

simply scroll down to it and press the Select Key .

Note on 93 kHz Frequency Use

The SR-60 offers two 93 kHz frequencies for Line Tracing. The default 93 kHz frequency has an actual cycle count of 93,623 cycles per second.

But some older transmitters use a different value for the nominal 93 kHz frequency, 93,696 cycles per second. This is found in the SR-60 listed as “93k-B”.

If you find that your transmitter signal at 93 kHz cannot be detected by the SR-60, set the locator’s frequency to 93-B kHz, which is set to the older value. Both 93 and 93-B frequencies can be found under the Line Trace category of the Frequency Selection sub-menu.

Sounds of the SR-60

The sound level is driven by the proximity to the target. The closer to the target, the higher the sound pitch will be. A rising tone indicates increasing signal.

In Active Line Trace or Passive Line Trace mode, sound is on one continuous curve and does not re- scale.

In Line Tracing modes, the default distortion response also activates an audio signal proportionate to the distortion in the detected field. When there is no distortion present, the sound of the SR-60 is a clear warbling sound when on the left side of the detected field, with a slight click added when on the right side of the detected field. If distortion is detected a sound similar to AM radio static sound can be heard, which gets stronger as the degree of distortion increases, similar to the unfocusing that signals distortion visually around the Tracing Line. If the distortion response feature is disabled, the static sound does not occur.

In Sonde Mode, if the sound level reaches its highest point, it will “re-scale” to a medium level and continue signaling from the new starting point.

In Sonde Mode, the pitch will “ratchet” upward. That is, it will rise and then re-scale (fall) in pitch while approaching the Sonde. Moving away from the Sonde, it will drop to a lower pitch and remain there as long as one moves away from the Sonde. Moving back toward the Sonde again it will resume rising in steps starting from the level it had reached previously. This serves as an indication when the
