TW-7700 RECEIVER

Display

Frequency Modes

The frequency at which the receiver is operating.

<< Left/Over Target>/Right>>

Indicates where the receiver is in relation to utility.

Numeric Display

Serves a dual function:

•Relative signal strength of the transmitted signal (% shown). Responds in conjunction with the bar graph. •Depth to the center of the target (when DEPTH pad is pressed - IN or CM shown)

Light

Indicates the display is lit (activated by pressing LIGHT pad).

Bar Graph

Serves three purposes:

•Responds in conjunction with signal strength. •Visual indicator for battery test (when BAT pad is pressed). •Volume loudness indicator (when VOL(up)/VOL(down) is pressed.

Replace Batteries

When the receiver batteries fall below a nominal level, REPLACE BATTERIES will be displayed.

No Signal

When no signal is received by the receiver, NO SIGNAL will display. This response may be due to the transmitter not being turned on, or the transmitter and receiver not be set at the same frequency.
