  3ENGLISH1 ABOVE ALL... SAFETY! 1.1 Symbols usedFor ease and convenience of viewing, NEPTUNE 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 impor-tant 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.1.2 Warnings1.2.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 interfe-rence.  This device is to be used solely as an aid to navigation.  Its settings may be influenced 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 naviga-tion, 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’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 performan-ce.  Unauthorized opening of the transceiver will nullify the warranty.1.2.b Radiofrequency/installation  Midland recommends following the requirements for prevention of radiofrequency expo-sure.  Unauthorized changes  or  modifications to this  device may invalidate conformity to  the  ETSI Regulations.  All  changes  or  modifications must  be  approved in  writing  by MIDLAND Corp.  This VHF DSC transceiver generates and irradiates electromagnetic energy (EME) at ra-diofrequency (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 regula-tions.  Not following these instructions can cause personal injury and/or malfunction of the device.  Do  not use  NEPTUNE  before  connecting  a suitable  antenna  that  is in  perfect  working condition  –  although  NEPTUNE  is  protected,  this  may seriously  damage  the stages  of transmission power.  Do not use transmit before ensuring proper connection of the antenna.  During transmis-sion, remain at a minimum distance of 1mt from the antenna.1.2.c Automatic Transmitter  Identification 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 Euro-pe which require the automatic transmission of identification.  For further details, please contact your local authorities.
4 ENGLISH1.2.d Environmental Pay attention to ambient conditions – although NEPTUNE 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 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 InformationETSI  (European  Telecommunications Standards Institute)  has  established specific  requirements (EN 301 025-1/2/3) for marine transceivers with DSC function class ”D”.  For use on non-SOLAS vessels.1.4 Registration of  your  Marine TransceiverFor using GMDSS and DSC functions, the operator must have a GMDSS radio operator’s certifi-cate (SRC or LRC) and apply for a ships MMSI number at the local radio authority.  Without MMSI number the radio can only be used as conventional VHF marine radio without DSC.  For seagoing ships, entering the European inland waterways you can apply for an additional licence and can obtain an ATIS number for the ship’s radio station. For ships, operating only on inland waterways, a ship’s licence can be obtained for ATIS mode only. Switching to ATIS mode is requested on all european inland waterways. In ATIS mode, automatically some restrictions of transmit power apply on certain channels, and some functions like Dual and Triple Watch are not available. Your distribu-tor may programm your radio according to your needs.1.5 AssistanceWe urge you to write the serial number of your transceiver in the space provided below.  This num-ber 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 _______________________1.6 Manual NotesWriting of  this manual  has been  completed with the  intention  of  supplying  information that are comprehensive, precise  and  up-to-date.

In any case, if any parts are missing, immediately contact your supplier.
10 ENGLISH4.2 Location for the transceiverBefore continuing, look for a place to install the transceiver which:•   Is far enough away from any device sensitive to magnetic/electromagnetic fields (e.g. compass) in order to avoid interference during their use.•   Allows for accessibility to the front panel of NEPTUNE.•   Provides easy connection to a power supply, for the antenna and for other cables.•   Has sufficient 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 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 qualified persons.4.3 Mounting of transceiverTo mount the transceiver to your vessel (see following picture):1.  Choose an appropriate location, as explained in the paragraph above.2.  Position the mounting bracket on the surface upon which it will be fixed, use a pencil to draw the 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.3. Remove  the  bracket,  drill  four  holes smaller  in  diameter than  the  screws,  and  reposition the mounting bracket, aligning it with the four holes.4.  Screw  in  the mounting  screws  and  ensure  the  bracket is  fixed  firmly, using  the  screws,  the grained washers, the flat washers and the nuts supplied.   If you are not able to reach the back part of the bracket surface to fix the nuts onto the screws, use threaded screws to fix the bracket.
  11ENGLISH5.  Tighten the screws with a screwdriver so that the bracket is firmly fixed to the surface.6.  Align the transceiver on the bracket, ensuring the holes of the internal part of the bracket line up with those on both sides of the transceiver (you can choose the preferred notch in order to best adjust the angle of the transceiver’s front panel for ease of viewing and use (15° of variation for each notch).7. Mount the mounting knobs on the two sides of the bracket to soundly fix the transceiver.  Keep the transceiver and microphone at a distance of at least 1 meter from all other ma-gnetic devices (e.g. compass) on your vessel.4.4 Adjustment of angleTo change the angle of inclination after installation:1.  Loosen the mounting knobs on the sides of the bracket.2.  Adjust the transceiver to a better angle, lining up the holes of the internal part of the bracket with those on both sides of the transceiver.3.  Tighten the knobs to fix the transceiver into place. 4.5 Installation of the antenna/electromagnetic exposure For optimal radio settings and minimal user exposure to electromagnetic radiofrequency energy, ensure that:•   The antenna is connected to the transceiver and is properly installed.•   The antenna is situated away from people and is positioned at least one meter from the tran-sceiver and microphone.•   The connector is a standard PL259 (male UHF).
12 ENGLISH4.6 Mounting of MicrophoneTo mount the microphone mount, look first for a mounting point close to the transceiver.  The distance between the transceiver and the wall mount must be less than the length of the mi-crophone cable.  Do not pull excessively on the microphone cord.  This part is  important  to  the  correct  function  of  the  device:  over time,  pulling  may  damage the  cord  and  impede  the user from transmitting. 4.7 ConnectionsRefer to the following diagram: 
  13ENGLISH4.7.a Power SupplyThe transceiver power supply must be 12Vdc (see specifics in par. 14).  The red cable must be connected to the positive pin, the black to the negative pin.  Warning! A faulty connection may seriously damage the radio!!  The power cable is equipped with a protection fuse. If the fuse shorts, look for its reason before substituting the cable with a new one of the same type and value.  Never short-circuit it, as this may damage the radio.4.7.b GPS deviceIf your NEPTUNE transceiver is connected to a GPS resceiver, such as the GPS 200, you can obtain and view NMEA information relative to the current position the vessel (latitude and longitu-de) and the local time with respect to Greenwich Mean Time (GMT).4.7.c AntennaThe antenna is an extremely important part of the device and noticeably influences the settings of any telecommunications device.  Contact your supplier regarding the antenna and request advice about how to mount and best connect it to your transceiver.  Warning!    Ensure  the  antenna  is  in  perfect  working  order.    It  may  otherwise  seriously damage the radio!  A periodical measurement of the stationary waves is advised using a suitable SWR metre. 5 BASIC OPERATION 5.1 Turning NEPTUNE on/offTo turn the transceiver on, rotate the OFF/VOLUME knob clockwise until it clicks on.  You will hear a beep (acoustic signal) and the LCD display will come on: the device is turned on to VHF mode.To turn the transceiver off, rotate the knob counter-clockwise until you hear further click: the LCD display will turn off.  If your transceiver is not connected to a GPS resceiver, it is necessary to insert manually your coordinates, otherwise an alarm will continue to sound.  For further details, see par.7.1.5.2 Volume regulationBring the OFF/VOLUME knob first to medium volume.  Once the transceiver picks up a signal, adjust the volume to a comfortable level.  If no signal is picked up, use the squelch control as described in the following paragraph and regulate the volume using background noise.5.3 Squelch RegulationSquelch is used to eliminate the annoying background noise you hear when no signal is being picked up.  If the squelch is adjusted correctly, there should be silence in between calls as well as a reduction in battery consumption.  To regulate squelch:1.  Rotate the SQ knob completely counter-clockwise until you hear background noise (if you don’t hear anything, turn up the volume) and bring up RX on the LCD display.2.  If  no signal is being received (only noise), slowly rotate the  SQ knob clockwise, stopping as soon as the noise and RX disappear stably.
14 ENGLISH  If  you  regulate  the  squelch  level  too  high  (closed),  you  may  hear  only  background  noise  or intermittent  discharges.    Correct  setting  of  squelch  is  also  important  for  reasons  discussed further on.5.4 Selecting an operating channel5.4.a With alphanumerical keypad 1.  Ensure that you are in normal operating mode (radio mode), otherwise press several times the button related to “RAD” or press the “C” button until the display shows: (A)2.  Select the desired channel and confirm by pressing the “E” button; the radio emits 4 beeps.    If there is no confirmation within 2 seconds by pressing the “E” button, Neptune will return to the previously used channel.   If a “notexistant” channel is inserted, for example CH99, or the radio does not beep 4 times for confirmation after pressing the “E”-button, NEPTUNE returns to the previously used channel.5.4.b Using the microphone buttons (UP or DOWN)1.  Ensure that you are in normal operating mode (Radio mode); otherwise follow  the procedure described in par. 5.4.a. 2.  Press repeatedly  the UP or DOWN buttons on the microphone to scroll through the marine channels until finding the desired channel.  Holding down one of the buttons will allow you to scroll quickly through the channels.  The marine band does not recognize some channel numbers.  Refer to the frequency table. The channels may have different receiving and transmitting frequencies (duplex channels) or may have the same (simplex channels).    Regulations  require  that  some  channels  operate  on  low  transmission  power  (see  Chap.1).  For this reason, NEPTUNE automatically switches to low frequency when these channels are selected.5.5 Transmission and reception  Transmitting without a perfectly functioning antenna may seriously damage the transcei-ver.The PTT (Push-To-Talk) button is located on the external microphone of your NEPTUNE.  To transmit:1.  Ensure that no one else is speaking.2.  Hold down the PTT button on the microphone.  TX will appear on the Diplay. 3.  Wait a second, then speak in a normal voice about 5 cm from the microphone.4.  When you have finished, release the PTT button: TX will disappear from the display.    Now NEPTUNE is in receiving mode (silent and waiting for a signal) where it will automatically receive any communication.5.6 Selecting high and low transmission powerThe transmission phase absorbs the most energy. To reduce the risk of wearing out the battery, we recommend selecting low transmission power when transmitting over short distances.  Hold the H/L button down (on the radio): Lo (low power) appears on the display.  When transmitting or receiving over long distances or with weak signals, press the H/L button again.  Lo will be A
  15ENGLISHreplaced with Hi (high power) on the display.  When the transceiver is tuned to a channel limited to low output power,  pressing the H/L button has no effect.5.7 Instant recall of channel 16Channel 16 is a security and distress channel.  This channel is used to establish initial contact with another station and for emergency communication.  This channel can be called up at any time by pressing button 16 on both the transceiver.  To return to normal operations, select another channel using the alphanumerical keypad or the UP/DOWN buttons on the microphone. By pressing a second time the 16 button, the radio returns to the previously  used channel before selecting channel 16.    Do not transmit on channel 16 unless absolutely necessary.  Doing so may impede emer-gency operations.5.8 Display lightingIf ambient lighting is insufficient for reading the display, the LCD display backlighting can be adjusted. Hold pressed the button    until a desired level is reached or until it has been comple-tely turned off. If the backlighting is activated, the display shows “LITE”. The chosen level of backlighting  remains stored,  also in case of extinction and successive turning on the radio.If you desire to switch off the backlighting immediately or if you like to reactivate the previously inserted level, press the    button.
16 ENGLISH6 SCANNING FUNCTIONS 6.1 Channel scanningNEPTUNE can automatically search for signals throughout the marine band by scanning, or selecting the channels in rapid sequence.  When a signal is detected, the scanning pauses on that channel and remains blocked until the signal ends.  Before the scanning automatically starts again, NEPTUNE waits for a few seconds in case the user wishes, if necessary, to respond to a call even if in truth you will see the channels being scanned. The NEPTUNE scanning happens with a minimum of 2 channels to a maximum of 56 channels on the INT band (channel 70 is not selectable).•   In order to execute the scanning of the marine channels, it is necessary to create a list of channels for scanning.  Operate in the following way: 1.  Select a channel you desire to insert into the the scanning list. 2.  Hold pressed for 2 seconds the function key corresponding to the word “SCAN” (B); the radio beeps twice  and  on  the  display  appears  for  a short  moment the indication “Scan Ena” (C).3.  If you desire to cancel a channel from the scanning list, repeat the pro-cedure  as  described  at  point  2.  In  that  case  the  display  is  showing “Scan Inn”. 4.  Once created your list, you can activate the scanning by pressing the function key corresponding to the word “Scan” (B).•   If you want to eliminate (useful if there are distortions) or to exclude mo-mentarily (useful for undesired conversations) a channel during scan-ning, operate as follows:  •   DEFINITIVE EXCLUSION OF A CHANNEL:  If your NEPTUNE is operating on a disturbed channel, press the func-tion key correponding to the word “Inn” (E) .•   MOMENTARILY EXCLUSION OF A CHANNEL:  Press the function key corresponding to the indication “Adv”  to advan-ce the scanning and to eliminate definitivly this channel from the scan-ning list. At the end of the complete scanning cycle, the channel pre-viously jumped will be monitored again.•   The  scanning  can  be  stopped  by  pressing  the  buttons  C,  or  button 16 on the microphone or by sending out a DISTRESS call. Your tran-sceiver will stop on the current channel (if you pressed button C) or on channel 16 (if you pressed 16 or PTT on the microphone).    Note:  Scanning  does  not  function  correctly  if  the  squelch  is  not  regulated  as  described  in par.5.3.  All scan modes are not enabled during ATIS mode (this is requested by authorieties) on inland waterways. 6.2 Dual Watch and Triple WatchThe meaning of these terms are:•   Dual Watch – allows the user to remain tuned to a channel of choice while periodically perfor-ming an automatic verification of signals on channel 16.•   Triple Watch – as written above, including a third channel chosen by the user. BCDE
  17ENGLISH6.3 Activation of Dual Watch/TripleTo activate Dual or Triple watch:•   Dual watch    - Select a desired channel and press the  D/W-button. The Display will  indicate “D/W”  and you will see the two monitored channels.   The Dual Watch function can be stopped in 5 different modes: by pressing  the PTT- or the “16” buttons on the microphone, “D/W”-  or “C”-buttons or by sending out a DSC-call.  •   Triple watch – select one of the 2 channels you desire to monitor to-gether with channel 16. Hold pressed the function key corresponding to the written T/W until you hear two beeps. Now on the display ap-pears the indication “User”.(F). Move now to the second channel you desire to monitor, press the function key corresponding to the indica-tion T/W.  Now you will see all three channels sliding on the display with indication T/W. “Adv” appears too, that, similar to SCAN function, has the aim to exclude momentarily the monitoring of the current channel.   The Triple Watch function can be stopped by  pressing the C-button, the  PTT- or the 16-buttons or by sending out a DSC call.    For both  modes,  the  operation  can  be reassumed  with  the  following diagram: F
18 ENGLISH  Similar to  scanning of marine channels, Dual Watch and Triple  watch  arrest when a signal is found and remain blocked for a few seconds after the signal disappears, in order to give the user a chance to respond to a call, if necessary.  Dual/Triple Watch cannot function correctly if the squelch is not correctly regulated, as described in par .5.3.  Because  of  regulations  for  inland  waterways, Dual/Triple  watch  can  not  be activated  in  ATIS mode.6.4 Memory channels (MEM mode)6.4.a Memory scanning  (SCAN MEMORY)1.  Similar to the scan function, memory scan will cycle sequentially throu-gh the channels, but only those, which have been pre-selected (at least 3). 2.  Press the function key corresponding to the indication “M/S” (G). The radio emits 2 beeps and on the display appears for ca. 2 seconds the indication “M/S Sel” (H).3.  Select another channel and repeat the procedure mentioned above.   In order  to  eliminate  a  channel erroneously inserted  into  scan  cycle, select the channel, press and hold the function key corresponding to the indication “M/S” until the display shows “M/S Del” (I)4.  Once  all  channels  are  stored,  the  scanning  can  begin  (SCAN  ME-MORY): Press the function key corresponding to the indication “M/S”. The channels will be monitored and the display will show the indication  “M/S” – which indicates the scanning of the stored channels, - “Adv” and “Del” in relation to the 2 function keys. Every time a signal/disturb is found on a channel, the scanning stopps for a few seconds in order to give the user a chance to respond to the call or to cancel the chan-nel, if necessary.   Note:  Scanning  does  not  function  correctly  if  the  squelch  is  not regulated as described in par. 5.3.6.4.b Reception/Transmission during SCAN MEMORY•   Reception:  If  NEPTUNE  finds  a  signal  the  scanning  interrupts.  The  display  indicates  “RX” instead of “M/S”  and the communication will be received through the loudspeaker.•   Transmission: It is possible to transmit at any time, also when the scanning is active. In that case NEPTUNE will always transmit on channel 16; if instead the transmission is done after a signal has been found, the device will  transmit on the previously busy channel. After the tran-smission the scanning comes interrupted.6.4.c To delete/To jump a pre-selected channel in memory If during the scanning a signal is received on an undesired or disturbed channel,  it is possible to cancel the channel in a definitive way or  to jump the channel momentarily. In order to execute these functions, the radio must be syntonized on a channel (firm scanning). Through the two function keys corresponding to  “Adv” and “Del”  you will have the possibility to jump the busy channel respective to cancel it from the pre-selected list of channels.There are 4 modes to stop the scanning of channels in memory:  1.  By pressing the PTT-button. 2.  By pressing the 16 button on the microphone or on the front panel 3.  By pressing the C-button. 4.  By sending out a DSC-Call.  GHI
  19ENGLISH7 USE WITH GPS 7.1 FunctionIf connected to a GPS receiver (GPS200), the transceiver will display the vessel position (latitude and longitude), as well as time data.  If information regarding position data are not received, in the normal radio mode, time data does not appear and a minute-long warning tone will sound (can be deactivated by pressing any button).  This tone will sound every 4 hours, reminding the user that position data needs to be inserted.  The user may also insert the coordinates manually as described in par. 10.6.7.2 GPS information on the displayRefer to the following illustrations: 1.  Position indicator  Displays GPS or manually-inserted coordinates.2.  Time indicator  Shows data supplied by the GPS or the transceiver’s clock.  8 DIGITAL SELECTIVE CALLING (DSC) 8.1 IntroductionDigital Selective Calling is a semiautomatic method for controlling VHF, MF and HF radio calls.  It was also designed as part of the global marine security and emergency response system (GMDSS).  It is likely that DSC will eventually replace audio calls on emergency frequencies and will be used to send urgent and routine radio-transmitted maritime security information.  This new service will allow crafts to send/receive calls of an emergency, urgent, security, or routine nature to/from vessels equipped with a DSC transceiver.  To avoid accidentally sending a distress call or a call sent incorrectly, contact your vendor or local authorities for updates on DSC operating and emergency procedures.  In European inland waterways DSC-function is not allowed.8.2 Mobile Marine Identification Service (MMSI)  Important!  To send/receive DSC calls, the user must program his personal MMSI code into the transceiver.  This is a nine-digit number used by marine transceivers equipped for DSC digital selective  calling.    This  number  is  used  much  like  a  telephone  number  for  contacting  other, specific vessels.  For further details on programming your MMSI, see par. 10.10.1 2
20 ENGLISH8.3 Navigating the DSC menuNEPTUNE offers many DSC functions. For this reason  it was created a specific menu of  settings and activations accessible via  the function keys as follows:1.  Access the “CALL”-Menu by pressing the related function key. 2.  Press the function key corresponding to the word “Type” to select the type of desired call.   Once inside a sub-menu, you can return at any time to the main menu by pressing the C-button and terminating the current operation.8.4 Individual call (ROUTINE TO)The user can carry out an individual call to a specific DSC station (a vessel or a costal station).  To carry out calls, you have to enter the  MMSI code manually or recall it from the preprogramed MMSI directory.  For further details on programming the MMSI directory, see par. 10.5. 8.4.a Sending an individual callYou can carry out an individual call using the following procedure: 1. Press briefly  the function key corresponding to CALL. On the display ap-pears (J): 2.  The outlined line below under “To Routine” appears if no owner name was inserted in the column “Dir”, otherwise a similar situation may appear (K):3. Press the function key  “Ch 06”  to access the sub-menu. 4. Press several times the  function key “Chan” in  order to select one of the 23 available channels (simplex channels) and confirm by pressing the E-button.5.  Like mentioned above, it is possible, to insert manually the address you desire to call (using the alphanumerical keypad), or to select one of the addresses previously stored (maximum  16) by pressing several  times the function key related to the word “DIR”. 6.  Then, after you have selected the communication channel and the ad-dress, the call can be carried out by pressing the function key corre-sponding to “Send” and confirmed by pressing the E-button. 7.  After the call execution the radio operates as follows:-   If you have carried out a call to a ship, after the call you will get an answer, the radio  will move to the channel previously selected under step 3-4.8.  At this point:-   If the call comes confirmed from the other part, the display shows the  message:  (L).  In  this  case  the  answer  is  reached  from  ship 100000000 and the possible communication channel will be CH06.  To  confirm  the  reception  of  the  received  message,  NEPTUNE  will emit an acoustic message that can be interrupted by pressing the function key corresponding to ”OK” or “STOP”.  Pressing OK beyond interrupting the acoustic signalling, NEPTUNE is syntonized on the communication channel (in our example 06).  If no function key comes pressed at that time (1 minute) the acoustic message will extinguish automatically. -   If the call does not come comfirmed, the display will indicate (M), by pressing the function key correponding to “Stop” the radio will return to the normal radio mode.   Once inside a sub-menu, you can return at any time to the main individual CALL-menu (Routine to) by pressing the C-button and terminating the current operation.JKLM
  21ENGLISH8.5 Group calling (Group Call)This function allows the user to call a specific group of stations which have the same MMSI group code memorized in their transceivers and which signals the audio channel the user wishes to speak on.  Therefore you can only carry out the group call when you have programmed the addresses in a directory like described in par. 10.10.8.5.a Sending a group call You can carry out a group call through following procedure:1. Press breafly the function key  correponding to “Call”.  On  the display appears: (N)2.

An acoustic alert will emit and the distress call will be carried out on channel 70 even when the channel is in use.  5.  After the distress call, the transceiver will simultaneously check chan-nel 70 and channel 16 on a receipt of DSC confirmation and meanwhile appears following: (T)6.  At this point:-   If the  distress  call is  received  and  confirmed  by  another  DSC  radio  station, the  acoustic alarm will stop sounding and the display will return to normal use in VHF mode on channel 16, sending on high transmission power.-   If no confirmation is received, the device will re-send the distress call at intermissions of 3.5 – 4.5 minutes (even with channel 70 in use), until a confirmation is received or until the user manually cancels the call through the C-button.   Pressing button 16, the transceiver will return to normal VHF operation, but the call will not be cancelled and the person who responded to the call may not have called off rescue operations.    If, at step 4, the user stops pressing the DISTRESS button before 5 seconds have elapsed, the distress call will not be sent.  To exit and return to VHF mode, press button 16.   The  acoustic  alarm  will  only  stop  definitively  once the  transceiver  has received  confirmation from the receiver of the call.  It is possible to arrest the acoustic alarm by pressing the button C or 16.  ST
