Default Frequencies

The Master Frequency Menu contains a large set of fre- quencies, but only some of these are made currently available. They are made “Currently Available” by check- ing them in the Master Frequency Menu, as described on page 23. The frequencies which are currently available ap- pear on the Main Menu when the Menu Key is pressed.

“Currently Available” frequencies can be checked in the Main Menu, in which case they will appear when using the Frequency Key. If they are unchecked in the Main Menu, they will not appear when using the Frequency Key to cycle through frequencies. Frequencies which appear in the Main Menu and are checked for activation are called “Checked-Active”.

Frequencies that are “Checked-Active” can be cycled through simply by pressing the Frequency Key (See Fi- gure 9). A frequency chosen by pressing the Frequency Key becomes the “In Use” frequency.

Currently available frequencies in default setting include:

Sonde Mode

• 512 Hz

Active Line Trace Mode

•128 Hz

•33 kHz

•1 kHz

•8 kHz

•262 kHz

Passive Line Trace Mode

• 60 Hz (Power)

The use of these features is described in the Sonde Locating, Active Line Tracing, and Passive Line Tracing sections.

Frequency Key – Used to set the “In-Use” frequency of the NaviTrack II from the set of checked-active fre- quencies. The list of frequencies that have been set to Checked-Active status can be modified via the Menu Key. Frequencies are grouped into three sets: Sonde Frequencies ( ), Line Trace Frequencies () and Power Frequencies ( ). Each press of the Frequency Key cycles to the next Checked-Active frequency.

Light Sensor – Detects light levels and controls the LCD backlight, which is set to come on under fairly dark conditions. The backlight can be forced on by cov- ering the sensor with your thumb.
