The
CHANNEL SWITCHES control the frequency synthesizer in the
receiver so it operates on the selected frequency. The first digit on
the far
left shows the Mhz range selected. It will be a 6 for 216Mhz,a 7 for
217Mhz, an 8 for 218Mhz, or a 9 for 219Mhz. Any other number selected
(0,1,2,3,4,5) will mute the receiver so no audio can be heard from the
speaker. The second or middle digit is for 100Khz increment selection
within the Mhz range selected by the first digit. The third digit to
the right
is for 10Khz increment selection within the 100Khz range selected by
the
second or middle digit. An imaginary decimal point is between the first
and
second digits. An imaginary 21 also precedes the first digit. An example
might be to set the CHANNEL SWITCHES to the frequency of
216.055Mhz. The first digit is set to 6,the second is set to 0,and the
third
is set to 5.The TUNE CONTROL is then used to select the last 5. This
exact example is shown on the receiver pictured. It is very important
to try
out the transmitters you are going to use in the field before needing
them. It
is helpful to have a list of CHANNEL SWITCH and TUNE CONTROL
settings that match with each of your birds and dogs.
