To manually enter a desired frequency such as 118.700 MHz, enter
1 1 8 7 0 using the numeric keypad. As each digit is entered, the flashing cursor moves
to the next digit. Five digits are always required to select a frequency. When the second
decimal place is a 0, the 0 must always be entered to complete the frequency selection.
That is why 118.700 MHz is selected by pressing 1 1 8 7 0 and not 1 1 8 7. The decimal
is automatically placed after the third digit entered.
The JD-100 will return to the previous frequency if there is a pause of five seconds or
more between key entries while entering a new frequency. The Clear Key may be
pressed any time prior to entering the fifth digit to clear the digits entered and return to
the previous frequency.
Any frequency outside of the range listed above will not be accepted. The JD-100 will
beep when such a digit is entered. The unit will automatically return to its previous
mode.
Frequency Search
To manually search through the frequency range (VHF and UHF), the Up Key or Down
Key may be pressed at any time to select the next higher or lower frequency. The Up and
Down Keys may be pressed repeatedly to continue changing the selected frequency.
To automatically search the entire COMM frequency range for a broadcasting signal, the
Up Key or Down Key may be pressed and held for one second. The screen will display
SRCH as seen below.
The frequencies will either scroll up or down depending upon whether the Up or Down
Key was used to initiate the Search.
When a broadcasting signal is found, the JD-100 will stop temporarily on that frequency.
If the broadcasting signal is cut off for more than two seconds, the Search will resume
until another signal is found. When 142.975 MHz is reached during an upward Search,
the Search automatically continues at 220.000 MHz. The Search continues in an upward
direction until 399.975 is reached, then the Search continues at 118.000 MHz. Likewise,
when 118.000 MHz is reached during a downward Search, the Search automatically
continues at 399.975 MHz.
During a Search the frequency range 143.000 MHz to 219.975 MHz will not be searched.
The Search may be canceled at any time by pressing the Clear Key. The direction of the
Search may also be reversed at any time by pressing and holding the Up or Down Key
(whichever is appropriate) for one second.
