This agreement is governed by the laws of Denmark. The public system has 57 channels, numbered CH 1 to 28 and 60 to 88, each of which has a certain purpose: intership, ship-to-port, or ship-to shore public.
You can have private channels, too. In US waters, the channels are different. Other waters like the Rhine have their own different systems, too. All large ships are obliged to monitor it constantly.
Never to be used for chatting, etc.! There are two types of channels, simplex and duplex: - On a simplex channel, both parties transmit and receive on the same frequency. Therefore you cannot talk and listen at the same time. You can therefore speak and listen at the same time. Note that everybody with a VHF receiver can listen to your conversation, but it is forbidden to use or pass on what is heard.
It is mainly used for getting in contact in order to establish verbal communication. Set the squelch level by means of the button 25W a.
Step down squelch level until noise is heard on free channel. Then step up to the first level where just silent. To listen for calls on other channels, select the channel number or use the scanning facility.
Hook off the handset. Press the PTT key on the handset. Switch to the channel agreed upon for example channel 71 and communicate: Press the PTT key when talking only. Select channel 16 or another channel specified or agreed upon: 2. When speaking, press the handset PTT key. Press Make the call: 1. Release the PTT key to listen.
When answered, agree upon a channel, switch to the channel for example channel 6 and communicate. Low power 1W is indicated by the indicator lamp on the display. Some channels may be programmed to operate at 1W level only. To change the TX power level press the soft key. The speaker icon on the display shows the speaker state.
The light can be set in four steps The button opens the DSC transmitter menu. It is possible to transmit, add or delete calls from here. Also, the function of each soft key placed to the right of the display is shown. Lower left corner of the display is the data area. Upper left corner of the display is used for textual instructions Opens the address book menu. To accept the data. To go to the next screen on the same subject. One step back.

US mode is used when sailing in US waters. BI mode is used when sailing on the rivers of Europe. Otherwise, the radio is in international mode. For US channels 13 and If the VHF is programmed with the set of US channels, some of those channels are specified to be used only with the limited transmitter power level of 1W. This means that the TX power level cannot be changed to 25W as described. Lift the handset to connect to the caller.
Each memory table may contain all channels available in the system. Press To distinguish between the tables, each table has a number and to each number can be attached a name of maximum seven Page 17 If scanning is in progress and a signal is detected on eg. Page Dual Watch To view contents of channels in a scan table: Dual Watch Viewing which channels a specific scan table contains, can be done The VHF set may perform a dual watch of channels, a priority in two ways: channel and the selected channel being monitored simultaneously.
While key is being pressed down, the VHF display will step through the channels of the scan table selected.
Page Intercom Intercom If your VHF system has more than one control unit, it is possible to carry out an intercom between two control units. When the intercom feature is used the VHF will perform as follows: Initiating an intercom from the VHF set to another control unit: To call another control unit: 1. Page 20 This indicates that a dial-up is in progress to the control unit with location number 2.
During the dialling time of 30 seconds it is possible to hook off the handset and speak into the microphone. Page Function Menu Function Menu Changing a Function There are a large number of function settings available, selectable from a functions tree, see next page.
This chapter only deals with the principles of how to use the functions tree. Example used: Changing the display contrast. Display: Backlight Page Vhf System Description When a control unit is master of the system, VHF System Description the other control units, if in VHF mode, show the following display to indicate that the transceiver is in use by another control unit: To the VHF system can be connected up to 7 control units.
Each control unit has a unique location Print page 1 Print document 31 pages. This agreement is governed by the laws of Denmark. Transmitter on 1. Transceiver weight 2. More than 70 dB Intermodulation att. More than 68 dB. Only use original screws; otherwise you risk short-circuiting the battery ground to the ship ground. For 24V DC supply an external power supply with the type number N can be used. The N is in principle a 24V DC to All common 50 ohm aerials which cover the used frequency range with a reasonable standing wave ratio, maximum 1.
The aerial is connected to the set by means of a 50 ohm coaxial cable with low loss, e. At the cable end a PL plug is mounted. These should be mounted in a place that is as high and clear as possible - as illustrated below. Note that the primary transceiver aerial must be placed at a higher level than the channel 70 receiver aerial. Channel 70 receiver aerial transceiver aerial Primary 2.
The loudspeaker signals are available in the SPARC-bus cabling, and a loudspeaker can be connected to the system in the handset hook parts or in the connection box. The table below describes the max. The length of the cable depends on the number of supply wires and the wire thickness. If the system supply voltage is 24V, i. The speaker output power depends on cable length and cable thickness as described in the table below.
Name Colour Twisted pair. Alternatively the GPS can be connected directly to the transceiver by means of a pole high density D-sub which is supplied with the radio, in the same pins as those mentioned above. Note: The cable length from battery to N depends on the wire thickness, but the voltage at the cable end at N should not be less than 18 volt.
Internal test call: The call is looped back internally, no activation of transmitter or receiver. Teaching Learning Process:- initially teaching learning process was teacher centric where teacher was the leader of the classroom and primary source of..
