WJ-8611 DIGITAL VHF/UHF RECEIVER
LOCAL OPERATION
3-3
3.2.4 POWER SWITCH
The POWER switch is a two-position rocker switch that applies power to
the receiver and initiates the receiver power up sequence. Pressing the
upper portion of the switch places the switch into the ON position.
Pressing the lower portion places the switch into the OFF position.
3.2.5 PHONE AUDIO CONTROL KNOB (PHONES)
The PHONES knob, located to the right of the PHONES jack, varies the
volume of the audio signal at the PHONES jack. It has no affect on the
rear panel audio outputs. A clockwise rotation of this knob increases the
volume of a nominal audio signal up to approximately 50 milliwatts,
maximum into a 600 ohm load. Counterclockwise rotation decreases the
volume level.
3.2.6 EDIT CONTROL KNOB (EDIT)
The EDIT control knob is a multiple function control that is used for
receiver parameter selection in configuration menu control, and in control
of memory and scan setup operations. Its controlled function is
determined by the current operation being performed with the dedicated
control keys.
3.2.7 TUNING WHEEL
The tuning wheel is a 2-1/2 inch diameter knob located in the lower right-
hand corner of the front panel. Its function is to change the receiver’s
tuned frequency. It is functional in the normal and step tuning modes of
operation. Clockwise rotation of the tuning wheel increases the frequency
in increments determined by the flashing digit in the frequency display or
by the programmed STEP TUNE SIZE in the step tuning mode. Counter-
clockwise rotation decreases the tuned frequency. The tuning wheel
permits tuning in a range from 0.00000 to 1000.00000 MHz. The
frequency display does not wrap around to the other limit (i.e., it will not
go from 0.00000 to 1000.00000 when decreasing and will not go from
1000.00000 to 0.00000 when increasing).
The tune rate, selectable from the configuration menu sets the rate that the
tuning wheel increments and decrements the frequency. With the FAST
rate selected, the greatest number of frequency changes per rotation of the
wheel is obtained, approximately 120 increments per rotation. The SLOW
rate provides fewer frequency changes per increment, approximately 15
increments per rotation. The accelerated rate selection provides a variable
rate of change. The number of frequency increments per rotation increases
as the wheel is rotated faster.
