- INTRODUCTION

The etón E1 is a microprocessor controlled, synthesized, world band receiver with continuous coverage capability from 100 kHz through 30 MHz and from 76 MHz through 108 MHz which includes the AM broadcast and shortwave bands as well as the FM broadcast band. The receiver offers excellent sensitivity, selectivity, dynamic range, and features that permit easy tuning of desired stations. Conveniently located front panel con- trols allow for rapid operator programming and ease of use. The units can be operated from either the supplied AC ADAPTER, an external 7 to 14 VDC source, or from four "D" cell batteries (not supplied) for portable opera- tion. A low battery voltage indication is displayed when that condition exists.

Three electronically switched IF filters are provided to provide optimum interference rejection for each mode. The front panel dot matrix liquid crystal display provides feedback of the current status of the receiver. The seven digit frequency display provides resolution to 10 Hz in the AM broadcast and Shortwave bands. Resolution to 20 kHz is displayed in the FM broadcast band. Backlighting of the display is selectable by a “LIGHT” key on top of the cabinet. To prolong battery life with internal battery operation, the backlighting automatically turns off after a short delay following a function change or retuning of the receiver unless it is specifically locked in the ON mode.

When the receiver is turned off, the display provides either the Local time or Greenwich Mean time (GMT), selectable in either the off or on state by the user. Reception modes include Single Sideband (LSB & USB) and AM in the Shortwave, MW (AM broadcast) and LW bands. For the LW, Shortwave and MW bands, a selec- table sideband synchronous detector (SYNC) allows for enhanced AM reception by eliminating or reducing dis- tortion due to fading signals or a strong adjacent signal. During FM broadcast use, stereo reception is available

through the use of headphones, or by connecting the line out jack to an external stereo system.

Other built-in reception aids include selectable slow, fast, or automatic AGC time constant, scanning of mem- ory channels, either by time or by carrier presence, pass- band tuning and squelch as well as treble and bass con- trols. Two independent, real time clocks provide Local or GMT time selection. Also provided are a two event timer, a SLEEP timer, and a SNOOZE mode.

A programmable memory area allows for 1700 indepen- dent receiver set up memories. The first 500 of these memory channels allow names to be attached to the frequencies and modes stored. The remaining 1200 memory channels allow frequencies to be stored by country. There are 111 country names factory stored in this bank of memory with 10 memory channels available per country and 90 memory channels remaining with no country assigned. These country names can be modified or added to by the user. These memories do not require battery backup and are thus unaffected by power inter- ruptions.

All parameters associated with a particular memory channel are stored including the frequency, mode, band- width, passband tuning setting, fast, slow, or automatic AGC and synchronous detector state. These memory channels may be accessed manually or through a time scan with each channel monitored for a 5 second peri- od, or carrier presence.

AC ADAPTERetón and EXTERNAL DC POWERING

The E1 receiver is supplied with an AC ADAPTER. The AC ADAPTER is designed to be plugged into a wall outlet that supplies AC power, or another source of exter- nal filtered DC power between 7 and 12 VDC may be used.

Connect the output connector of the AC adapter, or other power source, to the 9 VDC, 1 amp connector on the side of the receiver.

If batteries are installed and external power is lost, the receiver will continue to operate on battery power even with the DC plug inserted. If this occurs, the receiver will alert the user with a POWER LOSS indication, and with a POWER LOSS beep if the POWER LOSS beep feature is enabled. More details concerning power loss can be found on page 20, paragraph 27b.
