F. Selecting External Jack Frequencies (Tone Frequencies)

Menu/OK [5:Toggle to MAIN MENU] + >>More [SK:4] + [SK:5] + >>More [SK:d] + >>More [SK:h] + Tone/Freq [SK:k]

A coupler can be plugged into the External Jack

[15]([14] on 2550 locator) of the receiver and used to identify 50 Hz or 60 Hz cables. (See 19. Additional Applications: B: Cable Identification.) The same procedure as above (Section 5D) is followed for selecting frequencies that can be detected by the External Jack [15] ([14] on 2550 locator) found on the bottom of the receiver.

G. Creating User Defined Frequencies

Menu/OK [5:Toggle to MAIN MENU] + >>More [SK:4] + [SK:5] + >>More [SK:d] + Locate Freq [SK:f]

There are four user defined frequencies available on the receiver. (These frequencies must be between 50 Hz and 999 Hz.) These frequencies are found in the column on the far right of the Locate Freq display (Auxiliary frequencies). These frequencies, once programmed, will appear under the Aux [SK] frequency list when Freq [SK] is selected in the Locate mode.

To program the user defined frequencies press the right arrow [SK] to highlight the Auxiliary group of frequencies. Press the up/down arrows [SK] to highlight the user frequency to program. Press Enabl/Disabl [SK].

Press the left/right arrows [SK] to move the square cursor to a digit. Press Select [SK] to enter the number in the frequency field.

Press Menu/OK [5] to save the programmed frequency, or press Exit [SK] to cancel. The frequency will appear in the locate frequency display as U###, where ### represents the programmed frequency.

Note: To redefine a previously programmed user frequency, highlight the frequency, press enabl/ disabl, select the back arrow with the cursor, and press select to delete the previous entry.
