MARINE RADAR MODEL 1932 MARK-2/1942 MARK-2.
.
i SAFETY INSTRUCTIONS DANGER Radio Frequency Radiation Hazard The radar scanner emits electromagnetic radio frequency (RF) energy which can be harmful, particularly to your eyes. Never look directly into the scanner aperture from a close distance while the radar is in operation or expose yourself to the transmitting scanner at a close distance.
ii Two warning labels are attached to the display unit and scanner unit. Do not remove these labels. If labels are peeling off or are illegible, contact a FURUNO agent or dealer. WARNING To avoid electrical shock, do not remove cover. No user-serviceable parts inside.

vii SYSTEM CONFIGURA TION Note: Even though the display unit meets waterproof standard IPX-5, the connection of ex- ternal buzzer and/or remote display can af fect waterproofness. Watertight integrity cannot be guaranteed. When these modification has been done, the display unit should not be mounted where exposed.
1-1 1.1 What is Radar? The term “RADAR” is an acronym meaning Radio Detection And Ranging. Although the basic principles of radar were developed dur- ing World W ar II, echoes as an aid to naviga- tion is not a new development.

2-2 2.2 T urning the Radar On/Off Press the [POWER] key to turn the radar on or off. The control panel lights and a timer displays the time remaining for warm up of the mag- netron (the device which produces radar pulses), counting down from 1:30 to 0:01.
2-3 Note1: Availability of a particular display item depends on incoming data. Note2: When Range to W aypoint reaches 0.1 nm, the WPT marker jumps to dead ahead even though a difference may exist between heading and BRG to WPT . Note3: When cross track error exceeds 1 nm on either side, the XTE mark starts blinking.
2-4 Adjusting the A/C SEA control The proper setting of the A/C SEA should be such that the clutter is broken up into small dots, and small targets become distinguish- able. If the control is set too low , targets will be hidden in the clutter , while if it is set too high, both sea clutter and targets will disappear from the display .
2-5 2.10 Erasing the Heading Marker , North Marker The heading marker or north marker (avail- able with gyrocompass connection) may oc- casionally mask a target. T o view the target, you can temporarily erase the heading marker and north marker by pressing and holding down the [GAIN (HM OFF)] control.
2-6 2.12 Measuring the Bearing There are two ways to measure the bearing to a target: by the cursor , and by the EBL (Electronic Bearing Line). Measuring bearing by cursor Operate the omnipad to bisect the target with the cursor intersection. The bearing to the target appears at the bottom of the display .

2-8 2.15 Zoom The zoom feature allows you to double the size of the area between your vessel and any location within the current range to take a closer look at an area of interest.
3-1 3.2 Selecting the Presentation Mode With heading sensor connection, this radar provides four presentation modes: head-up, course-up, north-up and true motion. 1. Press the [MENU] key . 2. Operate the omnipad to select “MODE.” 3. Press the [ACQ/ENTER] key .
3-2 North up North is at the top of the display and the head- ing marker moves with ship’s heading. This mode is useful for determining ship’ s posi- tion and as a navigation monitor on a nauti- cal chart. The picture is stabilized against yaw of vessel, thereby reducing smear of target echoes.
3-3 3.5 Suppressing Radar Interference Radar interference may occur when near an- other shipborne radar operating in the same frequency band as your radar . Its on-screen appearance is many bright dots either scat- tered at random or in the form of dotted lines extending from the center to the edge of the display .
3-4 3. Select “6. Int Reject.” 4 . Select level desired by operating the omnipad. 5. Press the [ACQ/ENTER] key . 6. Press the [MENU] key to close the menu. IR1, IR2 or IR3 appears at the bottom right corner on the display when the interference rejection circuit is turned on.
3-5 3. Operate the omnipad to set the cursor on point C (or D). See Figure 3-8 (3). 4. Press the [GUARD] key . The asterisk dis- appears. See Figure 3-8 (4). Guard zone to set * G (IN) (2) Drag cursor to top left corner of zone and press [GUARD]. Asterisk blinking Drag cursor here.

4-2 4.3 Indirect Echoes Indirect echoes may be returned from either a passing ship or returned from a reflecting surface on your own ship, for example, a stack. In both cases, the echo will return from a legitimate contact to the scanner by the same indirect path.
4-3 4.5 SART (Search and Rescue T ransponder) A Search and Rescue T ransponder (SART) may be triggered by any X-Band (3 cm) ra- dar within a range of approximately 8 n.miles. Each radar pulse received causes it to trans- mit a response which is swept repetitively across the complete radar frequency band.

6 -1 6. OPERA TION OF ARP-10 (OPTION) CAUTION The plotting accuracy and response of this auto plotter meets IMO standards. Tracking accuracy is affected by the following: Tracking accuracy is affected by course change. One to two minutes is required to restore vectors to full accuracy after an abrupt course change.
6-2 6.1 General The Auto Plotter ARP-10 is an optional cir- cuit board which is accommodated in the dis- play unit of this radar (24 rpm only) radars. It requires heading data to function. The Auto Plotter permits manual or automatic acquisition and automatic tracking of up to 10 radar targets.
