3. Change the frequency (either using the arrow keys or by direct entry via the numeric
keypad followed by [
])
5. Press [STORE] to display the channel on the top row of the LCD.
6. Press [STORE] again to set the new frequency in the channel and automatically
switch back to Channel Mode with the new frequency displayed.
Change MHz
This key allows the MHz frequency to be changed in Frequency Mode. After
pressing [MHz] the first placeholder of the MHz frequency will flash and a new
3-digit number can be inserted from the numeric keypad. After inserting 3
digits the cursor moves to the first decimal place and the kHz frequencies can also be
changed if required. Pressing [
] at any time selects the new frequency. Pressing [
]
cancels any changes and returns to the previous state.
If a number below than the lower frequency limit or above the upper frequency limit is
entered, an ‘OUT OF RANGE’ message is displayed on the top row of the LCD. Enter a
valid frequency or press [
] to return to the previous one.
Delete
The delete key has three separate functions.
The main function, in Channel Mode, is to delete the contents of a channel. To do this,
display the channel to be deleted, then hold the [DEL] key down for 1 second.
Alternatively, press [STORE] to display a channel on the top row of the LCD. Display
the channel you want to delete and press [DEL] to delete it and return to Channel Mode.
The second function of the delete key is to delete characters under the cursor during
frequency or channel editing via the numeric keypad.
The third, and least intuitive, function of [DEL] is to toggle the selection/deselection of
all channels for scanning in scan mode (AC). When selecting channels for scanning,
[
] toggles selection of individual channels (displaying either SC or blank after
frequency and channel number in the top row of the LCD), whereas [DEL] toggles
between AC and SC or blank. When AC is shown, all channels are selected for scanning.
Pressing [DEL] returns all the channels to their previous state (SC or blank).
Numeric Keys
The numeric keypad is used to enter channels or frequencies.
When entering channel numbers, new digits are inserted in the right-hand place-holder
and shifted left if further characters are added. This is to eliminate the need to enter
leading zeros.
When entering frequencies, the cursor starts under the left-hand placeholder and moves
right as new number are added.
Accept
This key is equivalent to [ENTER] on a computer keyboard. It is used to accept
any changes being made via the numeric keypad.
Cancel
This is the ‘Cancel’ Key. Pressing it during any editing operation returns the
receiver to the state it was in before the editing operation began. Pressing [
]
in Scan Mode cancels scanning and returns the receiver to its previous mode.
