Table 1

The step size may be programmed per mode. The re-

ceiver, as shipped from the factory, has step sizes pro-

grammed as shown in Table 1 below:

To reset the receiver to the factory settings for STEP size,

AGC setting, BANDWIDTH, etc.:

Press the POWER button to turn the receiver off. Press the

CLR

button and hold while pressing the POWER button to

turn Power on. After three seconds, the receiver will reset.

The tuning wheel incorporates variable rate tuning. The

faster the tuning wheel is rotated, the greater the fre-

quency change per tuning wheel revolution.

BUTTON STEPS

The

button increases and the button de-

creases the frequency by fixed steps with each depres-

sion as programmed. Pressing and holding either button

will allow continuous stepping up or down as long as the

button is depressed. The fixed steps are as follows:

To tune in 100 kHz steps, press the

button. With the

displayed, press the / buttons, as desired,

to tune in 100 kHz increments.

Note that, regardless of the

/ button step

increments, the display always indicates the programmed

tuning resolution (step) available by using the tuning

wheel at any frequency.

11) Program Buttons -

SCAN

(Scan) - Pressing this button starts a scan as defined

by the scan indicators ( ) on the display.

Please refer to SCAN FUNCTIONS on pages 22-23 for

details.

MEM

(Memory) - Pressing this button in VFO mode switches

the receiver to memory mode. Please refer to MEMORY

FUNCTIONS on pages 20-21 for details.

V M

(VFO to Memory) - Pressing this button in VFO mode

transfers the current status of the receiver, for example,

frequency, mode, bandwidth, etc., into memory. Please

refer to MEMORY FUNCTIONS on pages 20-21 for details.

M V

M/KHz

(MHz or kHz Frequency Readout or Memory to VFO)

- Pressing the

button followed by the

M V

M/KHz

button,

changes the frequency readout to MHz or kHz as desired.

Pressing this button in memory mode transfers the con-

tents of the current memory location, i.e., frequency,

mode, bandwidth, etc. to the selected VFO. Refer to

MEMORY FUNCTIONS on pages 20-21 for details.

(Function) - Pressing this button accesses secondary

functions, printed in orange, on the numeric buttons 0-9

and switches the function line on the display above the 6

function buttons.

DEL

BEEP

- These buttons are normally used for direct

numeric entries in VFO, memory, clock, and timer modes.

Each button also has a secondary function printed in

orange. These secondary functions are used as follows:

Press

MEM

CARR

for programming scan methods.

Refer to SCAN FUNCTIONS pages 22-23.

Press

to access the clock. Refer to CLOCK &

TIMER FUNCTIONS page 25-26.

Press

LAMP

to adjust display and signal meter back-

light intensity.

Press

to turn audible beep on or off. Refer to BEEP

TONES page 15.

Press

DEL

to delete a program from a memory

location. Refer to DELETING A MEMORY LOCATION page

21.

CLR

(Decimal) - This button is used when entering a

frequency directly with the numeric buttons. Also used in

conjunction with the

button to provide a Clear entry

function. Refer to DIRECT FREQUENCY ENTRY page 16.

12) TONE - This control is used to modify the tonal quality

of the audio. Counterclockwise rotation increases bass

response. Flat response occurs at the 12 o'clock setting.

13) NOTCH - This control is used to “tune” the notch

frequency and is active when

AGC S F

NOTCH

is displayed. This

control is not active in FM mode.

14) Headphone - This connector accepts a standard

1/4" diameter 2-circuit (monaural) or 3-circuit (stereo)

phone plug. Audio is monaural in either case. All speaker

outputs are automatically switched off when using head-

phones.
