USAGE OF TARGET TRACKING FUNCTION
Attention
z There are the following limitations on use of the target
acquisition and target tracking functions.
[I] Resolution between adjacent targets and swapping during
automatic target tracking
Depending on the particular distance and echo size, resolution between
adjacent targets during automatic target tracking usually ranges
somewhere between 0.03 to 0.05 NM. If multiple targets approach each
other, resolution will become about 0.05 NM and this may cause the
system to regard them as one target and thus to swap them or lose part
of them. Such swapping or less of targets may also occur if the picture
of the target being tracked is affected by rain/snow clutter returns or sea
clutter returns or moves very close to land.
[II] Intensity of echoes and the target tracking function
The intensity of echoes and the tracking function have a correlationship,
and thus the target will be lost if no echoes are detected during six
scans in succession. If a lost target exists, therefore, radar gain must be
increased to support detection of the target. If, however, radar gain is
increased too significantly, sea clutter returns or other noise may be
erroneously detected and tracked as a target, and resultingly, a false
alarm may be issued.
[III]
Adverse effects of error sources on automatic tracking
To execute accurate tracking, it becomes necessary first to appropriately
adjust the [GAIN], [SEA] and [RAIN] dials of the radar so that the target
to be acquired and tracked id clearly displayed on the radar display.
Inappropriate settings of these adjustments reduce the reliability /
accuracy of automatic tracking.

PREPARATION
This section explains the features of the target tracking and AIS functions, and the initial setting for using each
function.
Target Tracking Function (Option)
The target tracking function calculates the course and speed of a target by automatically tracking the
target's move.
The target tracking function enables the automatic acquisition of targets by using the automatic
acquisition zone function.
The target tracking function also enables the simulation of the ship maneuvering method to avoid
collisions by using the trial maneuver function. (NCA-877WA)
If the mode is ground stabilization, SOG/COG used for own ship's information in target tracking. If the
mode is sea stabilization, SPD (speed through the water) / HDG (heading) used for own ship's
information in target tracking.

5.1.1 Collision Avoidance
Problems of Collision Avoidance in Navigation
Marine collision avoidance is one of the problems that have been recognized from of old. Now, it will be
described briefly who the collision avoidance is positioned among the navigational aid problems.
The navigation pattern of all mobile craft constitutes a system with some closed loops regardless of the media
through which the mobile craft travels, whether air, water, the boundary between air and water, or space. This
pattern consists of two closed loops in principle, one of which is a collision with another mobile craft and the
other is a loop of finding a right and safe way to reach a predeterminate destination. Fig. 5-1 shows the
conceptual diagram of navigation pattern by MR. E.W. Anderson. The closed loop of collision avoidance is
shown on the left side and the closed loop of finding a right course on the right side.
Fig. 5-1 Navigation Pattern
Marine Accidents and Collisions
Among marine accidents, collision accidents have been highlighted as the tonnages and speeds of ships become
higher along with the increase in traffic at sea. If a tanker carrying dangerous articles such as crude oil collides
with any other vessel, then not only the vessels involved with the accident but other vessels in the vicinity, port
facilities, inhabitants in the coastal area as well as marine resources may also suffer immeasurable damages and
troubles. Collision accidents have a high percentage of the marine accidents that have occurred in recent years.
To cope with these problems, any effective measures are needed and some equipment to achieve collision
avoidance requirements have been developed at rapid strides.
5-3
5.1 Preparation

Basic Concept of Collision Avoidance
There are two aspects in collision avoidance: collision prediction and avoidance. Collision prediction is to
predict that two or more vessels will happen to occupy the same point at the same time, while collision
avoidance is to maneuver vessels not to occupy the same point at the same time.
In practical operation of vessels, a spot of collision has to be deemed to be a single point but a closed zone. This
closed zone is conceptually defined as a CPA (Closest Point of Approach). In collision prediction, the time to be
taken until a ship reaches the CPA is defined as a TCPA (Time to CPA).
Fig. 5-2 shows a diagram caked “Collision Triangle”.
Fig. 5-2 Collision Triangle
5-4
Relative Vector and True Vector
From two points of view, collision prediction and avoidance, it is necessary to obtain the relative vector of other
ship for prediction and the true vector of other ship for collision avoidance in order to grasp other ship’s aspect.
The relationship between the relative vector and true vector is shown in Fig. 5-3.
Both rough CPA and TCPA can be obtained easily from the relative speed vector of other ship. This method has
an advantage that the risks of collision with all other ships within the radar range can be seen at a glance. On
the other hand, the course and speed of other ship can easily be obtained from its true speed vector, enabling
other ship’s aspect to be seen at a glance. Thus, the aspects of other ships (transverse, outsail, parallel run,
reverse run, etc. ) as described in the act of prevention of collision at sea can be readily grasped. If there is a
risk of collision with other ship, the operator can determine which rule to be applied and how to operate own
ship.

Radar and Collision Avoidance
Radar is still playing an important roll for collision prevention and positioning. A plotter is used to further
enhance the radar functionality. The plotter is capable of plotting other positions of other ships in 3 to 6 minute
intervals to monitor their movement. The plots of other ships represent their tracks relative to own ship, and it is
shown whether there is a risk of collision, namely CPA and TCPA can be obtained. This method using a plotter
is fairly effective, but the number of target ship, which is manually plotted, is limited and it takes several
minutes to measure those.

To switch between the true vector mode and relative vector mode, press the [VECT R/T] key.
[I] Vector Mode Selection
True Vector Mode
In the true vector mode, the direction of a target vector indicates the true course of the target and its vector
length is proportional to its speed.
In this mode, own ship’s vector is displayed as shown below.
In this mode, the movements of other ships around own ship can be accurately and easily monitored.
However, CPA Ring cannot appear in this mode.

Relative Vector Mode
The relative vector does not represent the true motion of the target, but its relative relation with own ship. This
means that a target with its relative vector directed to own ship (passing through the CPA Limit ring) will be a
dangerous target. In the Relative Vector mode, it can be seen at a glance where the CPA Limit of the dangerous
target is.
Therefore, the True / Relative mode shall optionally be used for the purpose of observation: the True vector
mode for grasping the true aspect of a target, and the Relative vector mode for grasping a target’s closest point
of approach (CPA).
[II] Vector Length (Vector Time)
The vector length of a target is proportional to its speed, and the vector time can be switched in a range of 1 to
60 minutes.
The diagram below illustrates a vector length of a target for 6 minutes, and the tip of the vector represents the
target’s position expected to reach 6 minutes later.

ground fixed.
Attention
z The reference target function is to be used if the own ship's
speed cannot be displayed normally due to trouble such as a
speed sensor malfunction. Do not use the reference target
function except in emergencies.
z If the speed or course of the own ship is changed or a new
reference target is set, the displayed speed may take 3 minutes
or more to reach the specified speed after the speed / course
change or the setting.
Even after 3 minutes or more has passed, the speed may differ
from the specified speed depending on the tracking condition.
z If a large radar echo such as a land target is set as a reference
target, the vectors of the speed and other tracking targets will
not be displayed correctly and may cause an accident.
z If a sailing ship is set as a reference target, the vectors of the
speed and other tracking targets will not be displayed correctly
and may cause an accident.
z If the

CPA / TCPA Alarm
CAUTION
Since these alarms may include some errors
depending on the target tracking conditions, the
navigation officer himself should make the final
decision for ship operations such as collision
avoidance.
Making the final navigation decision based only
on the alarm may cause accidents such as
collisions.
In the system, targets are categorized into two types: tracked / activate AIS targets and dangerous targets.
The grade of danger can easily be recognized on the display at a glance. So the officer can easily decide which
target he should pay attention to.
It is not possible to switch off the tracked target visual alarm, unless tracking is ceased, or the alarm condition
no longer applies.

Alarm for New Target Acquired in Automatic Acquisition Zone (New Target)
CAUTION
In setting an automatic acquisition zone, it is
necessary to adjust the gain, sea clutter
suppression and rain / snow clutter suppression
to ensure that target echoes are displayed in the
optimum conditions. No automatic acquisition
zone alarms will be issued for targets undetected
The automatic acquisition function sets a zone in a range and issues an alarm when a new target (which is not
yet acquired) goes into this zone.
For the setting of an automatic acquisition zone, refer to " Acquiring Target " in Section 5.2.1.

Attention
z If the gain, sea clutter suppression, rain/snow clutter

target alarm may be easily generated. So such
adjustments should be mad carefully.
When it is impossible to continue tracking any acquired and tracked target, or the data of AIS target cannot
received for a specified time, the LOST alarm will be generated. The typical causes for alarm generation are
shown below, but not limited to the following:
• The target echo is very weak.
• The target is shadowed by a shore or a large ship and its echo is not received.
• The target echo is blurred by sea clutter returns.
If a target under tracking goes out of a range of 32 nm and can no longer be tracked, it is canceled without a lost
target alarm.

TRIAL MANEUVERING
(TRIAL MANEUVER)
Attention
z Trial maneuvering is to simulate own ship’s course
and speed in the conditions that the course and
speed of a target ship are unchanged as they are.
As the situation is different from any actual ship
maneuvering, set values with large margins to CPA
Limit and TCPA Limit.
The trial maneuvering is the function of simulating own ship’s course and speed for collision avoidance when a
dangerous target appears. When the own ship's course and speed are entered in manual mode, the trial
maneuvering function checks if pre-acquired or pre-activated targets are dangerous.
The ranges of course and speed to be entered manually:
Course:
Speed:
360° (in 0.1° intervals)........................................................................... [EBL] dial
0 to 100 kn (in 0.1 kn steps)................................................................... [VRM] dial

Trial Maneuvering in the True Vector Mode
In the True Vector mode, calculations are performed according to the values set by Trial Speed, Trial Course
and other features, and the result is displayed as a bold-line that represents the change of own ship’s vector as
shown in the figure below (an example of the course changed to the right).
In this figure, the dangerous target forward left becomes safe as a result of simulation.
The tracked target information indicates the current CPA and TCPA values regardless of the result of
simulation.

Trial Maneuvering in the Relative Vector Mode
The result of Trial maneuvering in the Relative Vector mode is shown by a change in target vector. In the figure
below (in the same conditions as in the True Vector mode in the previous page), it is seen that the acquired
target is a dangerous one because its vector is crossing the CPA RING.
The above figure shows that the relative vector of the target has changed as shown in the figure as a result of
simulation (course and speed), so that the symbol color is changed into “White”, a safe target.
Irrespective of the simulation results, the current CPA and TCPA values are shown in the tracked target
information just like when the true vector mode is active.
The course change of own ship is displayed as a dotted-line.
Better information is provided by using relative motion and sea stabilization.

The radar operator has a role of interpreting the radar displays to provide his best aid in maneuvering the ship.
For this purpose, the operator has to observe the radar displays after fully understanding the advantages and
disadvantages that the radar has. For better interpretation of radar display, it is important to gain more
experiences by operating the radar equipment in fair weathers and comparing the target ships watched with the
naked eyes and their echoes on the radar display.
The radar is mainly used to monitor the courses of own ship and other ships in open seas, to check buoys and
other nautical marks when entering a port, to measure own ship’s position in the coastal waters relative to the
bearings and ranges of the shore or islands using a chart, and to monitor the position and movement of a heavy
rain if it appears on the radar display.
Various types of radar display will be explained below.
6.1
RADAR WAVE WITH THE HORIZON
Radar beam radiation has the nature of propagating nearly along the curved surface of the earth.
The propagation varies with the property of the air layer through which the radar beam propagates.
In the normal propagation, the distance (D) of the radar wave to the horizon is approximately 10% longer than
the distance to the optical horizon. The distance (D) is given by the following formula:
D=2.23( h1 + h2 )(nm)
h1: Height (m) of radar scanner above sea level
h2: Height (m) of a target above sea level
Figure 6.1 is a diagram for determining the maximum detection range of a target that is limited by the curve of
the earth surface in the normal propagation.

When the height of own ship’s scanner is 10 m for instance,
(a) A target that can be detected at the radar range of 64 nm on the radar display is required to have a height
of 660 m or more.
(b) If the height of a target is 10 m, the radar range has to be approx. 15 nm. However, the maximum radar
range at which a target can be detected on the radar display depends upon the size of the target and the
weather conditions, that is, the radar range may increase or decrease depending upon those conditions.
6-2
6.2
STRENGTH OF REFLECTION FROM THE
TARGET
The signal intensity reflected from a target depends not only on the height and size of the target but also on its
material and shape. The echo intensity from a higher and larger target is not always higher in general.
In particular, the echo from a coast line is affected by the geographic conditions of the coast.
If the coast has a very gentle slop, the echo from a mountain of the inland appears on the radar display.
Therefore, the distance to the coast line should be measured carefully.

Figure 6.2
Table 6.1 shows the graph indicating the relation between the target detection distance and the radar reflection
cross-sectional area (RCS) with regard to the type and the height of the target in a situation in which the
weather is good, the sea state is calm and the radio wave propagation is normal. As revealed by this table, even
on the same sea shore line, detection distance greatly differs depending on the height of the target from the
surface of the sea. Furthermore, because the target detection distance is greatly influenced by the shape and
material of the target and environmental conditions, such as the sea state, weather, and radio wave propagation,
caution should be taken when detecting distance of target.

SEA CLUTTER AND RAIN AND SNOW
CLUTTER
In addition to the echo required for observing ships and land radar video image also includes unnecessary echo,
such as reflection from waves on the sea surface and reflection from rain and snow. Reflection from the sea
surface is called "sea clutter," and reflection from rain and snow is called "rain and snow clutter," and those
spurious waves must be eliminated by the clutter rejection function.
[I]
Sea clutter
Sea clutter appears as an image radiating outwardly from the center of the radar display and changing
depending on the size and the shape of waves. Generally, as waves become larger, image level of the sea
clutter is intensified and the clutter far away is also displayed. When waves are large and the sea clutter
level is high, it is difficult to distinguish sea clutter from a small boat whose reflection intensity is weak.
Accordingly, it is necessary to properly adjust the sea clutter rejection function. Table 6.2 shows the
relation between the sea state (SS) showing the size of waves generated by wind and the radar's detection
probability.

As shown in Table 6.3, the number of SS increases as the wind speed becomes high and the waves become
large. Table 6.2 reveals that detection probability decreases from V (80 %) to NV (less than 50 %) as the
number of SS increases. Therefore, even if the sea state is calm and a target clearly appears on the radar
display, when the sea state becomes rough, target detection probability decreases resulting in difficulty of
target detection by the radar.

Significant wave height: an average of top N/3 higher waves when the number

For example, in the case of a standard marine buoy, RCS of X band radar is 5 m2 as shown in Table 6.1.
When observing such a target in the sea state (SS3) in which significant wave height exceeds 1.2 meters,
detection probability is M-NV, as shown in Table 6.2, which indicates 50 % or less.
[II] Rain and snow clutter
Rain and snow clutter is a video image that appears in a location where rain or snow is falling. The image
changes according to the amount of rain (or the amount of snowfall). As precipitation increases, the image
of rain and snow clutter becomes intensified on the radar display, and in the case of localized heavy rain,
an image similar to the image indicating land is displayed in some cases. Furthermore, because radio
waves tend to attenuate due to rain and snow, the ability to detect a target in the rain and snow clutter or a
target beyond the rain and snow clutter may decrease. The amount of attenuation depends on the
transmission frequency, antenna beam width, and the pulse length. Figure 6.3 and Figure 6.4 show
examples in which detection distance is reduced due to the influence of precipitation. Because of this, a
target, which clearly appeared up to 10 NM by an X band radar (pulse width of 0.8 μs) when it was not
raining, may become dimly visible up to 5 NM when the amount of rain becomes 4 millimeters per hour.
Furthermore, when comparing the X band radar with the S band radar, target detection distance decreases
less when an S band radar is used, which means it is influenced less by precipitation.

Sea Clutter and Rain and Snow Clutter

[III] Coping with sea clutter and rain and snow clutter
When the weather is bad and the ocean is rough, the use of an S band radar is effective because the radar is
not influenced by sea clutter so much and attenuation due to rain drops is small. When an X band radar is
used, reducing the pulse width will reduce the influence by spurious waves, and also the spurious wave
rejection function effectively works; therefore, the use of short pulse is effective when the weather is bad.
By using image processing functions PROC 1 to 3, it is expected that spurious waves are further
suppressed. Since optimal settings for those items can be automatically made by using the function mode,
it is recommended that STORM or RAIN be used by selecting the function mode when the weather is bad.
For details of the function mode, see Chapter 3.9.
However, these functions may make some targets invisible, particularly targets with higher speeds.

6.4
FALSE ECHOES
The radar observer may be embarrassed with some echoes that do not exist actually. These false echoes appear
by the following causes that are well known:
[I]
Shadow
When the radar scanner is installed near a funnel or mast, the echo of a target that exists in the direction of
the funnel or mast cannot appear on the radar display because the radar beam is reflected on the funnel or
mast. Whether there are some false echoes due to shadows can be checked monitoring the sea clutter
returns, in which there may be a part of weak or no returns.
Such shadows appear always in the same directions, which the operator should have in mind in radar
operation.
[II] Side Lobe Effect
A broken-line circular arc may appear at the same range as the main lobe of the radar beam on the radar
display. This type of false echo can easily be discriminated when a target echo appears isolated. (See
Figure 6.5)
Figure 6.5
[III] False Echo by Secondary Reflection
When a target exists near own ship, two echoes from the single target may appear on the radar display.
One of those echoes is the direct echo return from the target and the other is the secondary reflection return
from a mast or funnel that stands in the same direction as shown in Figure 6.6.
Figure 6.6
6-9
6.4
False Echoes
yy
yyy
[IV] False Echo by Multiple Reflection
When there is a large structure or ship with a high vertical surface near own ship as shown in Figure 6.7,
multiple refection returns may appear on the radar display. These echoes appear in the same intervals, of
which the nearest echo is the true echo of the target.
Figure 6.7
[V] Second Time Echoes
The maximum radar detection range depends upon the height of the scanner and the height of a target as
described in the section of “The Horizon for Radar Beam Radiation”. If a so-called “duct” occurs on the
sea surface due to a certain weather condition, however, the radar beam may propagate to a abnormally
long distance, at which a target may be detected by the radar.
For instance, assuming that the pulse length is MP3 (on the repetition frequency of 1400 Hz), the first
pulse is reflected from a target at about 58 NM or more and received during the next pulse repetition time.
In this case, a false echo (second time echo) appears at a position that is about 58 NM shorter than the
actual distance. If the false echo appears at 5 NM on the radar display, the true distance of the target is
5+58=63 NM. On the pulse length is SP1 (on the repetition frequency of 2250 Hz), a false echo may
appear at a position that is about 36 NM shorter than the actual distance.
This type of false echo can be discriminated by changing over the range scale (the repetition frequency),
because the distance of the target changes accordingly.
If second time echo is appeared, the use of Economy mode in PRF menu is effective. Otherwise, Stagger
Trigger menu set to on. (See section 3.8.3)
6-10
[VI] Radar Interference
When another radar equipment using the same frequency band as that on own ship is near own ship, a
radar interference pattern may appear on the radar display. This interference pattern consists of a number of
spots which appear in various forms. In many cases, these spots do not always appear at the same places,
so that they can be discriminated from the target echoes. (See Figure 6.8)
Figure 6.8
If radar equipment causing an interference pattern and this radar are of the same model, their transmitting
repetition frequency is nearly the same. As a result, interference patterns may be displayed concentrically.
In this case, the interference patterns cannot be eliminated by using only the interference reflector function,
so press [TX/PRF] key several times to fine-tune the transmitting repetition frequency.
An interference suppressing effect can be heightened by applying a different transmitting repetition
frequency to the interference pattern source radar and this radar.

DISPLAY OF RADAR TRANSPONDER
(SART)
The SART (Search and rescue Radar Transponder) is a survival device authorized by the GMDSS (Global
Maritime Distress and Safety System), which is used for locating survivors in case that a distress accident
occurs at sea. The SART is designed to operate in the 9 GHz frequency band.
When receiving the 9 GHz radar signal (interrogating signal) transmitted from the radar equipment on a rescue
ship or search aircraft, the SART transmit a series of response signals to inform the distress position to the
rescue and search party.
* This radar provides a shortcut item to make settings for SART signal reception. Execution of this item
automatically switches to the setting for SART reception.
It also functions for detect the beacon or target enhancer.
Procedures
1 Press [RANGE +] or [RANGE -] key to set the radar range to 6

[Example of Display]
Attention
z When the SART function is set to ON, small targets around own ship will
disappear from the radar display. So it is necessary to exercise full
surveillance over the conditions around own ship by visual watch in
order to avoid any collision or stranding.
If two or more sets of radar equipment are installed on own ship, use
one set of 9 GHz band radar for detection of the SART signal and
operate others as normal radars for avoiding collision, monitoring
targets around own ship, and checking on own ship’s position and
avoidance of stranding.
After end of detecting the START signal, turn the START display off.
Then the radar returns normally to the nautical mode.

ROUTINE MAINTENANCE
WARNING
Never carry out internal inspection or repair work
of the equipment by users.
Inspection or repair work by unauthorized
personnel may result in fire hazard or electric
shock.
Ask the nearest branch, business office or a
dealer for inspection and repair.
Turn off the main power before maintenance
work. Otherwise, an electric shock may result.
Turn off the main power before cleaning the

indicator if a rectifier is used. Otherwise,
equipment failure, or death or serious injury due
to electric shock may result, because voltage is
outputted from the rectifier even when the radar
is not operating.
For operating the radar equipment in the good conditions, it is necessary to make the maintenance work as
described below. If maintenance is made properly, troubles will reduce. It is recommended to make regular
maintenance work.
Common points of maintenance for each unit are as follow:
Clean the equipment.
Remove the dust, dirt, and sea water rest on the equipment cabinet with a piece of dry cloth.
Especially, clean the air vents with a brush for good ventilation.

Precautions in Mounting the Cover
When the cover is removed for regular checkup and replacement of parts and refitted after such work, the
procedures of fastening bolts shall be taken with the following precautions:
(a) The proper fastening torque of the fitting bolts (M8) is 1176 to 1470 N•cm (120 to 150kgf•cm) (which
makes the inside water-tight and protects the packings against permanent compressive strain).
The packings start producing from the cover at a torque of approximately 1470N•cm (150kgf•cm).
Do not fasten the bolts with a torque exceeding the specified value. Otherwise, the screws may be broken.
(b) Use an offset wrench of 11 mm × 13 mm or a double-ended wrench of 13 mm × 17 mm (not longer than
200 mm).
(c) Screw all the bolts by hand first to prevent them playing, then fasten them evenly in order not to cause
one-sided fastening. (Fasten the bolts with 25% of the required torque at the first step.)
*: Fasten the bolts in the diagonal order.

reflect on it, resulting in deterioration of radar
performance.
z Never use solvents of gasoline, benzine,
trichloroethylene and ketone for cleaning.
Check up and clean the radiator.
(2) Rotating section
(a) Supply Oil Seal
An scanner unit with a grease nipple needs grease supply. Remove the cap of the grease nipple on
the front of the radiator support, and supply grease with a grease gun.
Make the oiling every six months. The oil quantity shall be approximately 100 g, which is as much
as the grease comes out of the oil seal. Use the grease of Mobilux 2 of Mobil Oil.
(b) Oiling gears
Apply grease evenly to the tooth surfaces of the main shaft drive gear and the encoder drive gear
with a spreader or brush. Oiling in short intervals is more effective to prevent the gears from wear
and tear and extend their service life, but oil at least every six months.
Use Mobilux2 of Mobile Oil.
(c) Mounting legs
Check the mounting legs and mounting bolts of the scanner unit case for corrosion at intervals and
maintain them to prevent danger. Apply paint to them once a half year because painting is the best
measure against corrosion.

8.4.2 Replacement of Magnetron
Caution:
Replacement of magnetron must be made by specialized service personnel.
For details, refer to Service Manual.
When mounting a new magnetron, do not touch the magnet with a screwdriver or put it on an iron plate. After
replacement, connect the lead wire correctly.
Handling of Magnetron under Long-Time Storage
The magnetron that has been kept in storage for a long time may cause sparks and operate unstably when its
operation is started. Perform the aging in the following procedures:
(1) Warm up the cathode for a longer time than usually. (20 to 30 minutes in the STBY state.)
(2) Start the operation from the short pulse range and shift it gradually to the longer pulse ranges. If the
operation becomes unstable during this process, return it to the standby mode immediately. Keep the state
for 5 to 10 minutes until the operation is restarted.

FAULT FINDING
In case of semiconductor circuits, it is deemed that there are few cases in which the used
semiconductor devices have inferior quality or performance deterioration except due to
insufficient design or inspection or by other external and artificial causes. In general, the relatively
many causes are disconnection in a high-value resistor due to moisture, a defective variable
resistor and poor contact of a switch or relay.
Some troubles are caused by defective parts, imperfect adjustment (such as tuning adjustment) or
insufficient service (such as poor cable contact). It will also be effective to check and readjust
these points.
9.1.1 List of Alarms and other Indications
The system automatically recognizes an internal alarm and displays the alarm message. If an event
which is not trouble but must be reported to the operator occurs, the system notifies the operator

REFERENCE
Preheat Time after Change of Connection Pattern
After the current interswitch connection pattern has been changed, operation needs to wait until the
system is ready. This is because the preheat time varies depending on the previous connection of the
scanner unit and display unit.
The wait time is necessary for protecting the electronic tubes that emit radio waves.
a) When not changed to a new connection pattern
: Preheating not required
b) When changed to a new connection pattern and
an scanner unit had been used before the change : Preheating not required
c) When changed to a new connection pattern and
an scanner unit had not been used before the change
: Preheating required
Notes on Changing Connection Pattern
An attempt to change to another connection pattern immediately after the completion of connection
pattern change may fail.
This is because internal processing still needs some preparation time upon completion of connection
pattern change. Let several seconds pass between connection pattern change operations.
Notes on Connecting Slave Display Unit
Before a slave display unit can be placed in transmission state, the master display unit must be placed
in transmission state. If the master display unit is moved from the transmission state to the
transmission standby state, the slave display unit is forcibly placed in transmission standby state.
When they are in transmission standby state,
MTR Standby is shown in the alarm indication (Brilliance / alarm on page 2-9), and the alarm
sounds.
A slave display unit cannot control tune. Tune is controlled by the master display unit.
shown in the transmitter pulse length (upper left of the display on page 2-2).
Slave
is
Range change for a slave display unit is limited by the range and pulse length / repetition frequency of
the master display unit. As a rule, a greater range than the range of the master display unit cannot be
set for a slave display unit. However, if the transmitter pulse length of a slave display unit is identical
to the master display unit's and the repetition frequency is within the master display unit's, a greater
range than the master display unit's can be selected for the slave display unit. When the master display
unit narrows the range or changes the transmitter pulse length, the range of the slave display unit may
be forcibly changed. In this case, Master Range CHG is shown in the alarm indication (Brilliance /
alarm on page 2-9), and the alarm sounds.
