Keep curtains and other flammable materials out of
direct contact with the AC ADAPTER to avoid overheat-

BATTERY INSTALLATION
The
etón E1 receiver is also designed to operate from
four "D” cell batteries (not supplied). NOTE: Check the
batteries periodically for leakage. IF UNIT IS TO BE
STORED OR OTHERWISE NOT USED FOR AN EXTENDED
PERIOD OF TIME, REMOVE THE BATTERIES TO PREVENT
CORROSION AND POSSIBLE DAMAGE TO THE RECEIV-
ER. Damage caused by battery acid leakage is not cov-
ered under the warranty.
(1) Position the receiver with the front panel towards
you.
(2) Open the battery access door located at the lower
left corner of the front panel. (Shown as #5 in the
front panel drawing.)
(3) Inside you will find an additional door as shown in
the following illustration.
Remove this door by pressing down and pulling outward
on the “OPEN” tab.
(4) Insert the first of four “D” sized batteries into the
battery opening with the plus end of the battery to
your left. See the following illustration.
(5) Slide the battery to the right and continue in this
manner until all four batteries are installed. Replace
the inner door and close the outer door.
BATTERY OPERATION
The
etón E1 receiver does not rely on the batteries for
retention of memory channels. However, to insure that
clocks are maintained following the loss of AC power
and battery removal, the receiver must first be connect-
ed to a source of AC power or have batteries installed.
Clock settings are maintained for a time period of
approximately 10 minutes after all power is removed.
New batteries should be installed before this time peri-
od elapses or clock settings will be lost.

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
E1 also receives XM Satellite Radio (subscription
required), when the optional remote XM digital antenna
is connected.
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
GENERAL DESCRIPTION
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, bandwidth, 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
period, or carrier presence. The XM mode includes an
additional 20 memory locations for storing favorite XM
Satellite Radio channels.
POWER SUPPLY
AC ADAPTER and EXTERNAL DC POWERING
The
etón 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.
