knob will be ineffective, and “LOCK” and “TUN LOCK“ will appear on the LCD display. To return to normal operating mode, once again press the ‘CLEAR/LOCK’ key for three seconds.This control can also be used when the receiver is turned off. Press ‘CLEAR/LOCK’ for 3 sec- onds. A message will appear confirming lock. If power is then pressed, a “Press CLEAR/LOCK for 3 seconds to unlock” message will appear. The user must perform this action before the ‘POWER’ key will allow power up. From either MEMORY or COUNTRY modes. Note that VFO (Variable Frequency Oscillator) is a register used to store the frequency to which the main ‘TUNING’ control is set. Turning the ‘TUNING’ control will change this fre- quency.

7.FM / LW / MW / SW Mode - Function Softkeys The function of each of these softkeys is shown along the bottom edge of the display when the receiver is in the ON state. From left to right their functions when a menu is not displayed are as follows:

sideband (LSB). When AM synchronous detection mode is first selected using the ‘AM’ softkey, pressing the ‘SSB’ used to store the frequency to which the main ‘TUNING’ control is set. Turning the ‘TUNING’ control will change this frequency.

Pressing ‘TUNE’ transfers the frequency last listened to while in the MEMORY or COUNTRY modes to the VFO, along with the current associated function parameters.

This allows for fine tuning of and around the transferred frequency or modifying its parameters. When ‘TUNE’ is pressed, “VFO STORED” will briefly appear on the dis- play. This softkey is functional in MEMORY and COUN- TRY modes only.

8. < SELECT >

In VFO mode, pressing the ‘<’ or ‘>’ ends of this key will cause the frequency to increment or decrement in 5 kHz steps on LF and SW bands, in either 9 or 10 kHz steps on the MW (AM broadcast) band depending on a menu setting, and in 100 kHz steps on the FM band. When in

1. Squelch

This control allows muting of the receiver’s audio when no signals are present. Adjust the control until back- ground noise just disappears when no signal is being received. An indicator is provided on the display directly under the signal strength display to show how the squelch is set relative to received signal strength. (See the display description starting on page 18). Squelch also sets the threshold for carrier scan stop. Muting can be disabled in AUDIO SETTINGS menu, Item 4. However, carrier stop threshold will be controlled by the Squelch control regardless of whether or not muting has been disabled.

2. Treble

This control adjusts the audio frequency response at the high end of the audio spectrum. Adjust clockwise fo more treble response.

3. Bass

This control adjusts the audio frequency response at the low end of the audio spectrum. Adjust clockwise for more bass response.

4. Volume

With the receiver on, adjust this control clockwise to increase the audio level from the receiver’s speaker or from headphones. Be certain to set the volume setting at the desired level for TIMER use.

5. Access Door

Provides access to the battery access panel, to the microprocessor Reset button access hole, to the Display

Contrast Knob, and to the Factory Programming Connector. The Factory Programming Connector should be used only by a factory authorized service center. The Display Contrast Knob should be adjusted for best dis- play contrast from the normal viewing position. The Reset button “reboots” the microprocessor and should be pressed using a straightened paperclip in the unlikely event that the receiver exhibits erratic operation, “freezes”, or displays a flashing “UNLOCK” on the dis- play. (See the following diagram for the location of these items).

6. Direct- Key-Input

Numeric Keys - Keys 0 thru 9 plus the ‘.’ key are used to make direct numeric entries of frequencies, memory channel numbers, meter band designators, menu selec- tions, and timer settings. CLEAR / LOCK - Press this key to clear an incorrectly entered frequency or other value. Pressing and holding this key for three seconds will cause the receiver to be locked in its present configura- tion. All front panel key controls as well as the ‘TUNING’

MENU - Pressing this softkey displays the first of several menus used for setting clocks, timers and various other receiver functions. Each additional press advances to another menu page.

AGC - Pressing this softkey will toggle the AGC decay time between fast, slow, and auto in all modes but FM. When in FM mode, there will be no display function shown for this softkey.

BW - Press repeatedly to scroll through the three avail- able IF bandwidths of 7.0, 4.0, and 2.3 kHz in all modes but FM. When in the FM mode, there will be no display function shown for this softkey.

PBT - Pressing this softkey enables/disables the function of the PBT (passband tuning) knob in all modes except FM. The displacement in kHz of the IF passband relative to its nominal position is shown on the display directly above the PBT softkey when it is enabled. When in FM mode, there will be no display function shown for this softkey.

AM - Press to select AM (amplitude modulation) mode. When AM mode is selected, a second press of the soft- key selects AM synchronous detection mode (AM SYNC). Repeated depressions of this softkey will cycle the syn- chronous detection mode on and off. When in FM mode, there will be no display function shown for this softkey.

SSB - Press to select SSB (Single Sideband) mode. Once SSB mode is selected, repeatedly pressing the SSB soft- key will cycle between upper sideband (USB) and lower

MEMORY or COUNTRY modes, each press of the ‘<’ or ‘>’ ends of the key causes the display to decrement or increment respectively one memory page. When in MEMORY or COUNTRY modes, holding down the ‘<’ or ‘>’ will cause the unit to scroll through the MEMORY or COUNTRY pages. When programming in MEMORY mode, pressing ‘<’ or ‘>’ moves the curser left or right respectively for entering the names for stored frequen- cies.

9. STORE

This key is used to store various pieces of information including setting the Local and GMT clocks, setting parameters and labels in the 500 MEMORY channels, and saving parameters in the 1200 COUNTRY channels.

10. DELETE

Use this key to delete entries in the 500 MEMORY or 1200 COUNTRY.

11. TAG

Pressing this key adds (or removes) a tag shown as a “T” on MEMORY and COUNTRY displays from any of the MEMORY and COUNTRY for selective scanning.

12. T. SCAN

Used to initiate or stop a scan of MEMORY or COUNTRY channels marked with a “T” tag.

13. SEEK

Pressing the SEEK key will cause the frequency to incre- ment in 5 kHz steps on LW, and SW modes, 9 or 10 kHz steps in MW, depending on the setting of item 4 in the
