The Display
KHz
The KHz indicator is just below the CH indicator. It appears when you are
setting up search bank limits or anytime you press the INC button. After you
enter the lower and upper search limits, the scanner will flash the KHz indicator
to prompt you to enter a search increment value. This value is in kilohertz and
can be any number between 5 KHz and 955 KHz that is divisible by 5 or 12.5.
After you enter the increment value, be sure to press the ENT button.
You can change the INC value of a search bank at anytime while you are in the
bank. Just press INC, enter a new value, and press ENT. The new value is
permanently stored with the search bank parameters.
Key Lock
When the KEY LOCK indicator is on, it means that the keyboard has been
locked. This is provided as a protection so that you won't accidentally change
frequencies, interrupt a scan or search sequence, or otherwise modify your
current setup.
See the Key Lock button below
for more information.
FR. ERR
You may occasionally see the message FR. ERR in the display. This message
stands for "Frequency Error." You may encounter this message if you enter an
invalid frequency—something out of the AR1000's range. It also may occur if
you perform an operation with an incorrect sequence of steps.
To clear the FR. ERR message, simply press the CLEAR (decimal) key.
