SAFETY INSTRUCTIONS

WARNING

Radio Frequency Radiation Hazard

The radar antenna emits electromagnetic radio frequency (RF) energy which can be

harmful, particularly to your eyes. Never look directly into the antenna aperture from a

close distance while the radar is in operation or expose yourself to the transmitting

antenna at a close distance.

Distances at which RF radiation levels of 100 and 10 W/m²exist are given in the table

below.

Note: If the antenna unit is installed at a close distance in front of the wheel house,

your administration may require halt of transmission within a certain sector of antenna

revolution. This is possible - ask your FURUNO representative or dealer to provide

this feature.

1. MOUNTING

1.1 Antenna Unit

1.1.1 Mounting considerations

· The antenna unit is generally installed either on top of the wheelhouse or on the radar mast,

on a suitable platform. Locate the antenna unit where there is a good all-round view.

· No funnel, mast or derrick should be within the vertical beamwidth of the antenna in the bow

direction, especially zero degrees ±5°, to prevent blind sectors and false echoes on the radar

picture.

· It is rarely possible to place the antenna unit where a completely clear view in all directions is

available. Thus, you should determine the angular width and relative bearing of any shadow

sectors for their influence on the radar at the first opportunity after fitting.

· Locate the antenna of a direction finder clear of the antenna unit to prevent interference to the

direction finder. A separation of more than two meters is recommended.

· To lessen the chance of picking up electrical interference, avoid where possible routing the

signal cable near other onboard electrical equipment. Also avoid running the cable in parallel

with power cables.

· A magnetic compass will be affected if placed too close to the antenna unit. Observe the

following compass safe distances to prevent deviation of a magnetic compass: Standard

compass, 1.70 m (FR-2115-B), 2.10 m (FR-2125-B), Steering compass, 0.90 m (FR-2115-B),

1.20 m (FR-2125-B).

· Do not paint the radiator aperture, to ensure proper emission of the radar waves.

· The signal cable run between the antenna and the display is available in lengths of 15 m

(standard), 20 m, and 30 m. Whatever length is used it must be unbroken; namely, no splicing

allowed.

· The antenna base is made of cast aluminum. To prevent electrolytic corrosion of the antenna

base, use the seal washers and corrosion-proof rubber mat.

· Deposits and fumes from a funnel or other exhaust vent can adversely affect the aerial

performance and hot gases may distort the radiator portion. The antenna unit must not be

mounted where the temperature is more than 70°C.

· Leave sufficient space around the unit for maintenance and servicing. See the antenna unit

outline drawing for recommended maintenance space.

1.1.2 Assembling the antenna unit

The antenna unit consists of the antenna radiator and the antenna unit chassis, and they are

packed separately. Fasten the antenna radiator to the antenna unit chassis as follows:

1. For the XN20AF, XN24AF, attach two guide pins to the underside of the antenna radiator.

2. Remove the waveguide cap from the radiator bracket. The cap may be discarded.

3. Coat the waveguide flange with anticorrosive sealant as shown in Figure 1-1.

4. Coat fixing holes for the antenna radiator with anticorrosive sealant.

5. Grease the O-ring and set it to the O-ring groove of the radiator flange.

6. Set the antenna radiator to the radiator bracket.

7. For the XN20AF, XN24AF, coat hex bolts (M8X40, slotted washer-head, 8 pcs.) with

anticorrosive sealant and use them to loosely fasten the antenna radiator to the antenna unit

chassis. For the XN12AF, coat hex bolts, flat washers and spring washers with anticorrosive

sealant and use them to loosely fasten the antenna radiator to the antenna unit chassis.

8. For the XN20AF, XN24AF, remove two guide pins (inserted at step 1).

9. Tighten the bolts loosely fastened at step 7.

CAUTION

Be sure to remove the guide pins.

Injury may result if the guide pins loosen

and fall.

1.1.3 Fastening the antenna unit to the mounting platform

The antenna unit may be assembled before hoisting it to the mounting platform. However, do

not lift the antenna unit by the radiator. Always hold the unit by its housing. When using a crane

or hoist, lift the unit by the hoist rings which should be fastened to the bolt fixing covers of the

antenna housing.

CAUTION

DO NOT hoist the antenna unit by the

radiator; hoist it by the hoist rings. (Be sure to

remove rings after hoisting the antenna unit.)

RADAR 3 menu) and press the [ENT] key. Also, confirm that "2.MODEL" is set to "FR-2115,

2125" on the INITIAL SETTING 4 menu, following paragraph 3.2 and then pressing [RADAR

MENU], [0], [0], [0], [2], [0], [0], [0]. Trouble may result if the setting is wrong.

3.2 Accessing Menus for Initialization and Adjustment

1. Turn on the power.

2. Press the [RADAR MENU] key five times while pressing and holding down the [HL OFF]

key.

3.2.1 Restoring default settings

1. Press [RADAR MENU] [0] [0] [0] [2] [0] [0] [0] to display the INITIAL SETTING 4 menu.

2. Press the [0] key to select FACTORY DEFAULT.

3. Press the [ENTER] key five times, and turn the power off and on again.

2125" on the INITIAL SETTING 4 menu.

3.3 Adjusting Video Signal Level

When the signal cable is very long, the video amplifier input level decreases, shrinking target

echoes. To prevent this, confirm (and adjust if necessary) video amplifier input level.

1. Connect an oscilloscope to TP6 on the INT Board (03P9252) in the processor unit.

2. Transmit on the 12 nm range.

3. Adjust R21 on the INT Board so the value of TP6 is 4 Vpp. (For remote display, adjust R134

on the INT Board.)

3.4 Heading Alignment

You have mounted the antenna unit facing straight ahead in the direction of the bow. Therefore,

a small but conspicuous target dead ahead visually should appear on the heading line (zero

degrees).

In practice, you will probably observe some small bearing error on the display because of the

difficulty in achieving accurate initial positioning of the antenna unit. The following adjustment

will compensate for this error.
