5 DEPTH - When the proper conditions to measure depth are present,
pressing this switch will display the target's depth on the LCD (after a delay
of 2 seconds). The depth will continue to be displayed on the LCD, along
with the "depth symbol", for as long as the switch is depressed. If the switch
is pressed and quickly released, the depth will show on the LCD momentarily. The Rex
is factory set to display depth in feet and inches or in meters. If the depth cannot be
determined due to a weak signal or interference signal by other nearby utilities (congested
underground) the LCD will show 3 dashes "---".
6 SONDE - If the sonde mode is available, pressing this switch will cause the receiver to go
to the sonde mode of operation. If the receiver is already operating in sonde mode,
pressing this switch will cause the receiver to stop the sonde mode of operation.
7 FREQ - An operating frequency can be selected by depressing this switch consecutively
until the desired frequency is indicated on the display of the receiver. Some frequencies
are uniquely associated with the mode of operation selected (conductive, inductive or
inductive clamp); therefore the user should ensure that the same frequency is selected
on both the receiver and the transmitter.
Visual and Audible Indicators
The information display areas for the receiver are easy to understand. In addition, the receiver
has audible indicators to facilitate operation in heavy traffic or noisy areas. All visual indicators
for the receiver are on the LCD display, which has six general areas to display information
to the user: a Battery Indicator, a Gain Indicator, a Frequency/Mode Indicator, a Direction
Indicator, an Alphanumeric Display and a Volume Indicator.
• BATTERY INDICATOR - The battery symbol indicates the receiver's battery
status. When all 3 segments inside the battery symbol are present, the battery
is fully charged. When only the 2 bottom segments are present, the battery has
a medium charge. When only the bottom segment is present, the battery has
a low charge and should be replaced. If there are no segments present, the
battery is extremely low and you should replace it immediately.
• GAIN INDICATOR - The "Ⓐ” indicates that the gain is in the automatic
mode. In this mode, the receiver adjusts its sensitivity as a function of
the strength of the detected signal. No bar graph is shown in this mode.
If the "Ⓐ" is not visible, the receiver is operating in the manual gain
mode; therefore, a means to show the user the relative gain setting is
necessary. The bar graph indicates the relative strength of the gain.
