E1 MANUAL
Press the ‘SW BAND’ softkey to enter the shortwave
band tuning mode. The SW portion of the display indi-
cator will now be in reverse video. Now press the ‘SW
BAND’ softkey a second time.
The display indicator will now appear as “SW BAND”,
and the ‘METER’ number entry prompt on the display
will be flashing. (See #8 on the LCD Display
Description on page 18). At this point, you have
approximately 3 seconds to do one of the following:
(1) You can enter a shortwave band ‘METER’ number
with the ‘Direct-Key-Input’ keys. For example, key in
‘4', ‘1' for the 41 meter band.
(2) You can scroll through the available meter bands
using the ‘TUNING’ knob or the ‘< SELECT >’ key,
stopping on the desired ‘METER’ band. If you stop
on a “METER” band for more than 3 seconds, the
receiver will tune to that band, the “SW BAND”
indicator will appear as “BAND“, and the short-
wave band SW “METER” prompt will quit flashing.
To enter a shortwave band ‘METER' designator, press
the ‘SW BAND’ softkey to display a flashing ‘METER'
number entry prompt. The prompt will flash for approx-
imately 3 seconds after the ‘SW BAND’ softkey is
pressed. While it is still flashing, enter one of the listed
two or three digit Band numbers corresponding to the
desired ‘METER' band designator using the ‘Direct-Key-
Input’ keys. While the ‘METER' annunciator is flashing,
the ‘< SELECT >’ keys can also be used to step quickly
from band to band. After selection of the ‘METER’
band, use the ‘TUNING’ knob or ‘< SELECT >’ keys to
change the frequency, or press the ‘Direct-Key-Input’
keys to make a direct frequency entry.

(B) The SW band (1.8 - 30.0 MHz) frequencies are dis-
played and entered in kHz or MHz, depending upon
the user’s selection from item 5 of the RADIO SET-
TINGS menu. A maximum of 7 digits may be entered.
To make the menu selection, press the ‘MENU’ softkey
once. Then press ‘Direct-Key-Input’ key ‘5'. Repeatedly
pressing the ‘5' key toggles between kHz and MHz as
the display and entry method for the SW band. Leave
the reverse video entry 0on the desired display
method. For example, line 5 on the menu should
appear as follows for entry in kHz:
“ 5 SW BAND ENTRY kHz / MHz“.
After making this selection, press ‘Direct-Key-Input’ key
‘9' to exit the menu. Note that if kHz is selected from
the menu, the display will show frequencies from 1.8 -
30.0 MHz in Kilohertz, and entries should be made in
kHz.
Example:
14,258.1 kHz
Press ‘1', ‘4', ‘2', ‘5', ‘8', ’.’, ‘1', ‘.’ **
OR Press ‘1', ‘4', ‘2', ‘5', ‘8', ‘.’, ‘1', ‘0' *
If MHz was selected from the menu all frequency
entries should be made in MHz.
Example:
14.2581 MHz
Press ‘1', ‘4', ‘.’, ‘2', ‘5', ‘8', ‘1', ‘.’ **
OR Press ‘1', ‘4', ‘.’, ‘2', ‘5', ‘8', ‘1', ‘0' *
* When the maximum number of allowed digits is
entered, the 7th digit acts as an enter key, and a sec-
ond ‘.’ need not be entered.
** The second depression of the ‘.’ key acts as an
‘ENTER’ and causes immediate response to the
GETTING STARTED continued
entered frequency. If you do not press the decimal ‘.’ a
second time at the end, the receiver will automatically
enter the frequency after a slight delay.
(C) FM broadcast band enters and displays in MHz
(megahertz) regardless of the RADIO SETTINGS menu
setting. A maximum of 5 digits may be entered for FM.
Examples:
97.7 MHz
Press ‘9', ‘7', ‘.’, ‘7' ‘.’ **
107.7 MHz
Press ‘1', ‘0', ‘7', ‘.’, ’7', ‘.’ **
OR Press ‘1', ‘0', ‘7', ‘.’, ‘7', ‘0' *
Attempting to enter a frequency outside the tuning
range of the
etón E1 receiver will cause the ERROR
annunciator to flash and an error beep to be heard.
The receiver will then return to its previous settings.
SHORTWAVE ‘METER' BAND DESIGNATOR ENTRY
To facilitate tuning to particular sections of the short-
wave band that contain many worldwide broadcasts of
news, information and music, the
etón E1 receiver per-
mits entry of the ‘METER' band designator. In some
cases, the worldwide broadcast station may not
announce its exact operating frequency, but will
announce the ’METER' band in which it is operating or
to which band it will move to improve worldwide
reception at a particular time of day. By entering this
'METER' band number, the receiver automatically tunes
to the low frequency end of the corresponding
‘METER' band. The search for the new station location
is thus limited to a particular smaller section of the
entire shortwave band spectrum.
The Shortwave Band Designators and corresponding
frequency ranges are as follows:

FRONT PANEL LOCK (UNLOCK)
All front panel keys (with the exception of the ‘CLEAR /
LOCK’ key), as well as the ‘TUNING’ knob can be
locked if desired. First, be sure the E1 receiver is not in
T.SCAN or SEEK mode. Press and hold the
‘CLEAR/LOCK’ key which is one of the ‘Direct-Key-
Input’ keys. The “LOCK” and “TUN LOCK” annuncia-
tors will appear indicating the front panel controls are
locked out. ‘‘VOLUME’, ‘BASS’, ‘TREBLE’, and
‘SQUELCH’ are still functional. Press and hold the
‘CLR/LOCK’ key to unlock. The “LOCK” and “TUN
LOCK” annunciators will disappear, indicating the front
panel controls are once again active. The ‘CLEAR / LOCK’ key may be used even when the radio is off to
lock the ‘POWER’ key to prevent accidental power acti-
vation.
AM SYNCHRONOUS OPERATION
For general tuning and listening, normal AM is best. If,
however, the received signal sounds distorted, or inter-
ference from adjacent stations is present, AM synchro-
nous should be engaged. The synchronous detector in
your receiver can greatly reduce the severe audio dis-
tortion that can occur due to signal fading. The detec-
tor also permits selectable tuning to either the upper
or lower sideband portion of an AM signal. Since most
