FREQUENCY and CHANNEL Displays
20 The synthesiser provides a six-digit frequency display and a two-digit channel display. The displays
have four functions:
❏
Monitor Function. The displays show the current operating frequency and channel number.
❏
Edit Function. The edit function is indicated by a flashing decimal point at the bottom
right-hand end of the frequency display. Edit function shows information being entered from
the keypad, not the radio’s current operating parameters.
❏
View Function. View facilities allow channel information to be displayed without affecting the
operation of the radio. This can be used, for example, to check the frequencies stored in each
of the 99 pre-set channels; during such checks, the radio’s operating frequency does not
change.
❏
Error Message Function. Error messages are automatically displayed if invalid keypad
entries are made, or when certain fault conditions are detected. Error messages are detailed in
Table 4-5 on page 34.
Second Function Select Key
21 The second function select key (SHIFT s) is a push-to-select, push again to de-select key, that
selects either the primary or second function of the keypad. When second function is selected, the
adjacent indicator is lit. When primary function is selected, the adjacent indicator is unlit.
Third Function Select Key
22 The third function select key (SHIFT t) is a push-to-select, push again to de-select key, that selects
either the primary or third function of the keypad. When third function is selected, the adjacent indicator
is lit. When primary function is selected, the adjacent indicator is unlit.
Numerical Data Keys 0 through 9
23 Primary function data keys 0 through 9 are used to enter numeric data.
Decimal Point Key
24 The primary function decimal point key, adds a point to the right of the last number entered. If this is
the first key entry, the display will blank and a 0 (zero) followed by a decimal point will be entered in the
first position.
Cancel Entry (CE) Key
25 The primary function CE key cancels previous selections as follows:
❏
If the previous selection was a numeric data key, the last digit entered will be replaced by a
blank. Further use of the CE key progressively removes remaining digits from the display;
pressing the CE key when only one digit is shown causes the display to go to the monitor
mode.
❏
If the previous key entry resulted in an error code (refer to Table 4-5), pressing the CE key
restores the settings shown before the previous key entry.
❏
If the previous entry was as a function key, then the key entry is ignored.
