1. ABOVE ALL... SAFETY!
1.1 Symbols used
For ease and convenience of viewing, NEPTUNE 100 uses symbols to highlight urgent situations, practical advice, and general information.
Warnings such as this, shown using an open hand symbol, indicate a crucial description  regarding technical repairs, dangerous conditions, safety warnings, advice and/or important information. Ignoring these symbols may result in serious problems and/or damage and/or personal injury.
Notes such as this one indicate practical advice that we suggest be followed for optimal

performance with NEPTUNE 100.
1.2 Warnings
1.2.a General
This device has been tested for compliance with Class D digital marine device limits. These  limits were created to allow for reasonable protection against damaging interference.
This device is to be used solely as an aid to navigation. Its settings may be inuenced by 
diverse factors, such as defects or malfunction of the device, environmental conditions or improper use.
It is the user’s responsibility to observe reasonable prudence and judgement in  navigation, and as such this device should not be considered a substitute for this reasonable prudence and judgement.
Do not open the radio for any reason! NEPTUNE 100’s precision mechanics and electronics  require expertise and specialized equipment; for the same reason, the radio should under no circumstances be realigned as it has already been calibrated for maximum performance. Unauthorized opening of the transceiver will nullify the warranty.
1.2.b Radiofrequency/installation
Midland recommends following the requirements for prevention of radiofrequency 
exposure. Unauthorized changes or modications to this device may invalidate
conformity to the ETSI Regulations. This VHF DSC transceiver generates and irradiates electromagnetic energy (EME) at 
radiofrequency (RF), and as such must be installed and placed in operating conditions that are in conformity with the instructions contained in this manual and with current regulations. Not following these instructions can cause personal injury and/or malfunction of the device.
Do not use NEPTUNE 100 before connecting a suitable antenna that is in perfect working  condition – although NEPTUNE 100 is protected, this may seriously damage the stages of transmission power.
Do not use transmit before ensuring proper connection of the antenna. During  transmission, remain at a minimum distance of 1mt from the antenna.
1.2.c Automatic Transmitter Identication System (ATIS)
Your marine transceiver may activate, if necessary, the ATIS function. The ATIS function  may be activated when using the transceiver within the internal navigable waters of
Europe which require the automatic transmission of identication. For further details,
please contact your local authorities.

ENGLISH
1.2.d Environmental
Pay attention to ambient conditions – although NEPTUNE 100 is designed to operate  under the most severe conditions, it is important to avoid exposure to environments that are excessively humid or dusty, or to temperatures outside the –15 to +55°C range. Also avoid exposure to direct sunlight.
Avoid jarring and excessive vibration – NEPTUNE 100 is built to resist mechanical shock  and vibration as long as these are within the norm for any electrical device.
Do not use this device in potentially explosive environments. A single spark may cause  an explosion.
1.3 ETSI Information
ETSI (European Telecommunications Standards Institute) has established specic requirements
(EN 301 025-2/3) for marine transceivers with DSC function class ”D”. For use on non-SOLAS vessels.
1.4 Assistance
We urge you to write the serial number of your transceiver in the space provided below. This number is found on the back panel of the transceiver and will be useful in the event of repair/ assistance and/or loss and/or theft.. Serial number ________________________________
1.5 Manual Notes
Writing of this manual has been completed with the intention of supplying information that are comprehensive, precise and up-to-date. Nevertheless, the manufacturer does not assume responsibility for the actual correspondence with the product and for the consequences of possible errors caused by factors over which it has no control.

2. INTRODUCTION
2.1 Generalities
Congratulations for choosing Midland’s marine transceiver NEPTUNE 100. This product is a high performance, mobile VHF DSC marine transceiver. The following are its principle features:
Equipped with all international channels • available (correctly assigned).
High transmission power of 25W• , which allows the user to maintain contact from large
distances, and a low transmission power of 1 W to reduce consumption during short-distance communication.
Principal commands duplicated on the microphone • for faster accessibility – channel
selection and channel 16 recall.
Back lit LCD display and adjustable contrast• – constantly shows NEPTUNE 100’s parameters
and settings and occurs an optimal visualization.
Possibility to program 20 private channels • by means of the optional programming kit “PRG
NEPTUNE 100”. We remind that the use of private channels is controlled by the national
competent authorities: for this reason, we suggest you contact the local radio communication authorities.
Extraordinary capability for water resistance• , conforms to the standard IPX7.
Recall button for Channel 16 • – for instant access to channel 16 (the universal marine channel
for emergency contact).
NMEA• connection – use the interface cable supplied for easy connection from transceiver to
optional GPS system, such as GR213 or other compatible GPS. Once connected, the display will show the automatically updated coordinates (latitude and longitude) and time data.
DSC Digital Selective Calling• – for security on the water and the ability to make quick
calls automatically (the transceiver supports DSC (Digital Selective Calling) operations with
a specically designed DSC unit which conforms to the ITU-R standard, M493-11 Class D
requirement).
MMSI directory• , which simplies the sending of DSC calls to frequently called contacts and
allows viewing of contact name on the display.
Mounting on adjustable bracket• for stable and comfortable positioning in any condition.
Connection to an external speaker • (optional) – for listening to communications further away
from the transceiver.
The manufacturers, in their effort to constantly improve product quality, reserve the right to

change the above characteristics without forewarning. For eventual updates, visit www.cte.it or contact your authorized dealer.

4.2 Location for the transceiver
Before continuing, look for a place to install the transceiver which:
Is far enough away from any device sensitive to magnetic/electromagnetic elds •
(e.g. compass) in order to avoid interference during their use. Allows for accessibility to the front panel of • NEPTUNE 100. Provides easy connection to a power supply, for the antenna and for other cables.•
Has sufcient space close by for installation of the microphone support.• Allows for mounting of the antenna at least 1 meter from the transceiver.•
The universal mounting bracket supplied allows for mounting of the transceiver high up (with 2
the bracket above the device) or on the bridge (with the bracket below the device) with an angle range of 45°.
Warning! Installation and connections must be performed in part by qualied persons.
4.3 Mounting of transceiver
To mount the transceiver to your vessel (see following picture):
Choose an appropriate location, as explained in the paragraph above.1. Position the mounting bracket on the surface upon which it will be xed, use a pencil to draw the 2.
position of the four holes where the screws will be inserted.
Ensure that the surface intended for the transceiver mounting can be drilled into without  provoking damage to other parts of the vessel and be careful to not drill right through it.
Remove the bracket, drill four holes smaller in diameter than the screws, and reposition the 3. mounting bracket, aligning it with the four holes.
Screw in the mounting screws and ensure the bracket is xed rmly, using the screws, the 4. grained washers, the at washers and the nuts supplied.
If you are not able to reach the back part of the bracket surface to x the nuts onto the  screws, use threaded screws to x the bracket.
Tighten the screws with a screwdriver so that the bracket is rmly xed to the surface.5. Align the transceiver on the bracket, ensuring the holes of the internal part of the bracket line up 6.
