NOTICE
This equipment has been tested and found to comply with the limits for
a Class B digital device, pursuant to Part 15 of the FCC Rules.  These
limits are designed to provide reasonable protection against harmful
interference in a residential installation.  This equipment generates,
uses and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful
interference to radio communications.  However, there is no guarantee
that interference will not occur in a particular installation.  If this
equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or
more of the following measures:
— Reorient or relocate the receiving antenna.
— Increase the separation between the equipment and receiver.
— Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
— Consult the dealer or an experienced radio/TV technician for
help.

ensuring your enjoyment of this high-performance transceiver, which
should provide you with many years of satisfying communications even in
the harshest of environments. STANDARD HORIZON technical support
personnel stand behind every product we sell, and we invite you to contact
us should you require technical advice or assistance.
We appreciate your purchase of the ECLIPSE+, and encourage you to
read this manual thoroughly, so as to learn and understand the capabilities
of the ECLIPSE+ fully.
The STANDARD HORIZON (a division of VERTEX STANDARD)
ECLIPSE+ is a VHF/FM transceiver designed for use in the frequency
range of 156.025 to 163.275 MHz.  The ECLIPSE+ requires 13.8V ± 20 %
for operation and has a switchable RF output power of 1 watt or 25 watts.
The transceiver operates on all currently-allocated marine channels which
are switchable for use with either USA, International, or Canadian
regulations.  It has an emergency channel 16 which can be immediately
selected from any channel by pressing the red 16/9 key. NOAA Weather
channels can also be accessed immediately by pressing the WX key with
channel selection.
Other features of the transceiver include: scanning, priority scanning,
NOAA Weather Alert and submersible microphne.

3 CONTROLS AND INDICATORS
NOTE
This section defines each control of the transceiver. See Figure 1 for
location of controls. For detailed operating instructions refer to chapter
4 of this manual.
3.1 CONTROLS AND CONNECTIONS
qPOWER SWITCH/VOLUME CONTROL
Turns the transceiver on and off as well as adjusts the audio volume.
When the power is turned on, the transceiver is set to the last selected
channel.
Secondary Use
When the transceiver is turned on while the SCAN and WX keys are held
down, the internal microprocessor is reset. This clears the memory and all
user-programmed settings, such as scan memory assignments. This
condition is known as the default condition, the same as when shipped
from the factory.  For a list of these defaults, see the section on Resetting
the Transceiver’s Microprocessor.
wSQUELCH CONTROL (SQL)
Sets the point at which random noise on the channel does not activate
the audio circuits but a received signal does. This point is called the
squelch threshold. Further adjustment of the squelch control will
degrade reception of wanted transmissions.
eKEY PAD
16/9 Key
Immediately recalls channel 16 from any channel location. Holding
down this key recalls channel 9.
Secondary use
Please see secondary use for the WX key.

WX Key
Immediately recalls the previously selected NOAA weather channel
from any channel location.
Secondary use
1. Holding down the 16/9 key while pressing the WX key changes the
mode from USA to International or Canadian.
2. Holding down the WX and SCAN key while turning the power on resets
the microprocessor and erases scan channels from memory. This clears
the memory and establishes the factory-set defaults. For a list of these
defaults, see the section on Resetting the Transceiver’s Microprocessor.
SCAN Key
1. Starts and stops scanning of programmed channels.
2. Memorizes the selected channel into the transceivers scan memory
for scanning. When pressed and held down again it, DELETES the
channel from the scan memory.
Secondary use
1. If held while the UP or DOWN key is pressed, the transceiver will
show the channels in scan memory.  This function will not work if the
unit is scanning.
H/L Key
Toggles between high and low power.  When the H/L key is pressed
while the transceiver is on channel 13 or 67, the power will temporarily
switch from LO to HI power until the PTT is pressed. The H/L key does
not function on transmit inhibited and low power only channels.
UP 
 and DOWN  Keys
The UP 
 and DOWN  keys are used to select channels.
rEXTERNAL SPEAKER JACK
Connects an optional external speaker to the transceiver. Use a
speaker with an impedance of 4 or 8 ohms, with an RCA phono plug.
t ANTENNA JACK
Connects an antenna to the transceiver. Use a marine VHF antenna
with an impedance of 50 ohms.
