MARINE VHF RADIOTELEPHONE Instruction Manual
.
CAUTIONS AGAINST HIGH VOLTAGE Radio and radar devices are operated by high voltages of anywhere from a few hundred volts up to many hundreds of thousands of volts. Although there is no danger with normal use, it is very dangerous if contact is made with the internal parts of these devices. (Only specialists should attempt any maintenance, checking or adjusting.) There is a very high risk of death by even a few thousand volts, in some cases you can be fatally electrocuted by just a few hundred volts.
First aid ☆Note points for first aid Unless there is impending danger leave the victim where he or she is, then begin artificial respiration. Once you begin artificial respiration, you must continue without losing rhythm. (1) Make contact with the victim cautiously, there is a risk that you may get electrocuted. (2) Switch off the machinery and then move the victim away slowly if you must. (3) Inform someone immediately (a hospital or doctor, dial emergency numbers, etc.).
☆If the victim has a pulse but is not breathing (“Mouth to mouth” resuscitation) Figure 1 (1) Place the victim’s head facing backward (place something under the neck like a pillow). (2) Point the chin upward to widen the trachea. (3) Pinch the victim’s nose, take a deep breath, then put your mouth over the victim’s mouth and exhale completely, making sure that your mouth completely covers the victim’s mouth. Then remove your mouth. Repeat this routine 10 to 15 times per minute (holding the nostrils).
☆If the victim has no pulse and is not breathing (Heart massage in combination with artificial respiration.) Figure 2 If the victim has no pulse, his or her pupils are dilated, and if you cannot detect a heartbeat, the heart may have stopped, beginning artificial respiration is critical. (1) Put both hands on the diaphragm, with hands on top of each other keeping both arms straight (If your elbows are bent, you cannot push with as much power).

Operation 4.2 Basic communication procedure The following describes basic radio communication procedures. 4.2.1 Turning ON the power CAUTION Do NOT turn off the power of the equipment when at sea because the SOLAS Convention requires keeping CH16 watch at all times. ■ Procedure ■ 11.. Press the PW R CONT key for one second. The controller and transceiver will start the internal check. After finished it correctly, the status display will appears.
Operation 4.2.2 Turning OFF the power ■ Procedure ■ 11.. Press the PW R CONT key and the DIM key simultaneously. After that, the power-off process is activated according to the controllers' situation. When using only one controller Select the desired item below on the displayed popup screen at right. ・ [OK]: Turns off the power. ・ [Cancel]: Returns to the previous screen. When using two or more controllers Select the desired item below on the displayed popup screen at right.
Operation 4.2.3 Communicating with the radiotelephone The VHF radiotelephone is operated by means of a handset. ■ Procedure ■ 11.. When operating on a controller without the access rights (OCC is displayed), press the jog dial to obtain the access right. After obtaining the access right, disappears OCC mark on the screen and the controller becomes accessible to the VHF transceiver. Also, just lifting a handset from the cradle enables to obtain the access right.
Operation ■ Making a radiotelephone call ■ 11.. Select CH16 or other agreed channel. 22.. Lift the handset from the cradle. 33.. Press the PTT key, and make a call as described below. z Say the calling station name ... Repeat 3 times. z "this is" z Say own ship name ... Repeat 3 times. z "over" 44.. Release the PTT key to listen. 55.. When answered and agree on a working channel, change to that channel. 66.. After checking that no station uses the working channel, begin conversation.
Operation 4.2.4 Receiving with scanning Scanning function enables to watch multiple channels (additional channels) with the priority channel (CH16). If found receiving signal on the additional channels, the dwell time on that channel will be longer, but continued to watch the CH16 alternatively. The scan mode can be selected from the following modes. ・ All CH scan Mode: ・ Memory CH scan Mode: ・ Select CH scan Mode: Scans all channels in the current channel mode. Scans all memory channels.
Operation the CH16. If squelch is closed again, the scanning will resume 2 seconds later. - If the squelch is opened on an additional channel, remains on that channel and CH16 alternatively (in a cycle of 0.14/1.86 seconds). If squelch is then continuously closed (until the end of the scan cycle), the scanning will resume. Furthermore, added to the additional channel, if the squelch is also opened on the CH16, paused scanning and continues to watch on the CH16 as described above. 4.2.
