e. Lock Indicator - The LOCK indicator is a unique feature of Sure-
Lock. When the LOCK indicator appears on the display, the receiver is
locked to the signal being generated by the transmitter. This indicator
assures the operator of adequate signal strength for measurements on
the conductor.
f. Bubble Level - The bubble level is used to manually position the re-
ceiver vertically to engage the automatic calculated depth function. The
bubble level may also be used in manually cross checking calculated
depth, especially uneven surfaces (Hills).
g. Frequency Select Switch - The frequency select switch is used to toggle
the receiver through its individual frequencies.
h. Estimated/Calculated Depth Indicator - The estimated depth indicator
provides a continuous reading of estimated depth in inches or centi-
meters for a quick, real-time reading during locating. Changing the
estimated depth readings alert the operator of potential factors which
may affect locating accuracy. An automatic calculated depth reading
will replace the estimated depth reading when applicable.
i.
Volume Level Indicator - This 3 stage indicator relates to the speaker
volume currently selected. Successive presses of the ON-OFF/VOL-
UME switch toggles through increasing volume, receiver power off,
receiver power on and back through the 3
speaker volume levels.
j.
Speaker (not shown) - The speaker provides two distinctly separate
audio tones, which correspond to the bar graph and directional ar-
which is lower in pitch, corresponds to the conductor being to the left
**NOTE**
WHEN THE LOCK INDICATOR BECOMES INTERMITTENT OR DISAP-
PEARS FROM THE DISPLAY, THE OPERATOR HAS EXCEEDED THE
MAXIMUM RANGE OF THE TRANSMITTER SIGNAL. DEPTH WILL
NOT BE CALCULATED IF THE LOCK INDICATOR IS NOT STEADILY
ILLUMINATED. THE TRANSMITTER SHOULD BE REPOSITIONED OR
SET TO HI POWER IN ORDER TO IMPROVE THE SIGNAL STRENGTH.
**NOTE**
THE SURE-LOCK IS AVAILABLE WITH THE DEPTH READOUT IN CEN-
TIMETERS. THIS FEATURE IS PRESET AT THE FACTORY.
