SET SCAN
The SET SCAN key sets the dwell time for the SCAN and SEARCH functions. It issues a prompt:
Scan time (m:ss.ss)
(0:05.00)>
The format for the numerical input is shown on the top line meaning minutes, seconds, and
hundredths of seconds. The current default value is shown at the bottom left. The receiver then
waits until it receives five numeric inputs which it automatically formats with the colon and
decimal. Shifted or non-numeric keys (except ESC) are ignored. The scan time is then set
according to the received five-digit value. Pressing the ESC key causes the function to abort
without updating. On exit, the power-on default display (frequency and gain) is restored, with
the scan time now appearing in the lower left corner as follows:
149.220MHz Gain=70
0:05.00T
SET ∆
The SET ∆ ("set delta") key is used to set incremental values of frequency, gain or time for use by
the increment and decrement functions (arrow keys). Which variable is set depends on which of
the three other "set" keys (SET F, SET G, or SET SCAN) were activated last. The three prompts
are:
Delta G (01-99)
(01)>
Delta F in kHz (001-999)
(001)>
Delta T in secs (01-99)
(01)>
The top line shows the range of values accepted and the number of digits that must be entered.
The current default value is shown in the bottom left corner.
SHIFT
The SHIFT key selects the functions on the upper half of the keys. When SHIFT is activated the ^
symbol appears in the lower right corner of the display. When the batteries are low, the ^
symbol is replaced by a small picture of a battery. The SHIFT key is also used as a "continue" or
"confirm" operator in SEARCH mode and to return from HELP.
If SHIFT and ESC are pressed simultaneously, a hardware reset will occur. This is exactly the
same as turning the receiver off and on again. If you should experience a lockout (receiver won't
respond to keys) or find yourself in a place from which you can't escape, pressing ESC and
SHIFT simultaneously is your last resort.
