5-20 Chapter 5: Programming
Tone On/Off
The Hex A tag selects the Tone On/Off programming parameter, which offers two
options, On and Off. The Hex 0 tag turns the Good Read Tone off and the Hex 1 tag
turns the Good Read Tone on.
Tone Frequency (Hertz)
The Hex B tag sets the frequency of the Good Read tone. Each time the Hex B tag is
scanned, the tone increments one unit. After reaching the highest frequency, the
sequence starts over with the lowest frequency. End this mode by scanning the End
tag or another valid Hex tag.
The Good Read Tone frequency can have one of the following eight values:
702 Hz
781 Hz
868 Hz
961 Hz
1071 Hz
1187 Hz
570 Hz
633 Hz
Tone Length (Milliseconds)
The Hex C tag sets the length of the Good Read Tone. Each time the Hex C tag is
scanned, the tone length changes from the shortest to the longest, and then back
again. End this mode by scanning the End tag or another valid Hex tag.
The Good Read Tone length is from 15 ms to 225 ms in 15 ms increments
(15 total values).
Tone Volume
The Hex D tag selects the volume of the Good Read tone by increasing it as the Hex D
tag is repeatedly scanned. After the loudest volume is reached, the sequence begins
again with the softest volume. End this mode by scanning the End tag or another
valid Hex tag.
There are eight different volume settings available on the RealScan 74. However, there
is a programming sequence which allows the user to access eleven volumes. Refer to
the Volume Adjust section in this chapter for details on activating the eleven volumes
and other functions of the volume button.
