Front Panel Controls
6
The Scout has four front panel controls. The functions of each are briefly described below. A
more detailed discussion of the functions of the front panel controls is given in the OPERATION
section.
POWER
The POWER switch activates the Scout. When the POWER switch is in the ON position, the
Scout is powered from the internal NiCad battery pack. If external power is present then a trick-
le charge cycle can occur. When the POWER switch is in the OFF position and the Scout is pow-
ered from an external power source, the battery pack will charge automatically.
FILTER
The FILTER switch, in conjunction with the CAPTURE switch, is used to select the operating
mode of the Scout. When the FILTER and CAPTURE switches are both in the OFF position,
NORMAL mode is selected, and the Scout functions as a conventional frequency counter. When
the FILTER switch is in the ON position and the CAPTURE switch is in the OFF position, FIL-
TER mode is selected. When the FILTER and CAPTURE switches are both in the ON position,
CAPTURE mode is selected. When the FILTER switch is in the OFF position and the CAPTURE
switch is in the ON position, RECALL mode is selected. The FILTER switch also has an alterna-
tive function. When the Scout is turned on with the FILTER switch in the ON position, the LCD
EL backlight is enabled. Turning the Scout on with the FILTER switch in the OFF position dis-
ables the LCD EL backlight.
