WJ-8611 DIGITAL VHF/UHF RECEIVER
LOCAL OPERATION
3-33
frequency, stop frequency, increment size, and the dwell timer setting are
preset by the Setup menu. All of the other operating parameters must be
selected in the manual mode before the scan is started.
When a scan is in progress, it may be stopped using one of two methods.
Pressing the SCAN key, when the scan is in progress, stops the scan and
places the receiver into the manual operating mode. The receiver remains
set to the last parameters set by the scan mode. When the scan is stopped
with the PAUSE key, the scan is placed into a pause mode. In this mode,
both the SCAN and PAUSE LEDs are lit. The scan stops and full manual
control is restored. However, this mode allows the scan to be restarted at
the point it was halted, without having to return to the beginning of the
sequence. When in the pause mode, pressing the PAUSE key again
resumes the scan at the point where it was halted. Pressing the SCAN key
when in the pause mode, terminates the scan and places the receiver into
the manual operating mode.
3.6 RECEIVER COLD START
The receiver Cold Start operation provides a means of quickly clearing all
receiver memory, resetting the front panel parameters to a default setting,
and resetting internal registers in the receiver circuitry. This operation is
performed by holding the CE key in the pressed position while the
receiver is powered ON. When the words “COLD START !” are
displayed in the parameter display, the cold start operation is complete and
the key can be released. At the completion of the cold start, the receiver is
set as follows:
Tuned Frequency
20.00000 MHz
Tuning Resolution
10 Hz
IF Bandwidth
10.0 kHz
Detection
AM
Gain

3.7 BUILT IN TEST FUNCTION
The built-in-test function (BITE) tests the internal circuitry and critical
receiver functions to verify proper receiver operation. This function is
performed each time that the receiver is powered ON, and any BITE
failures are reported to the front panel. If one or more failures occur,
pressing the CE key clears the error report from the front panel display. If
multiple errors are reported, the highest priority is reported first. Pressing
the CE key clears the first report, and displays the next in the list. When
all errors have been reported, the normal receiver display is restored. The
possible error conditions are as follows:
SRAM FAILURE
RAM write/read test failure
