Operation
The target must always be used with its longest side vercal.
Switch the unit o when not in use to preserve the baery.
!
The target is water resistant to IP66.
However, do not submerge the unit in water.
To Switch the Target ON:
1. Press the ON/OFF buon on the top of the unit.
2. The green light should be permanently lit when unit is in operaon.
Under normal condions with a fully charged baery,
the rechargeable target will operate connuously
for up to 640 hours before it needs recharging.
!When the unit is switched on and no green light is shown,
then the baery requires charging.

Charging
The rechargeable target should be fully charged before use.
A full charge takes approximately 24 hours.
!DO NOT charge targets in an explosive
atmosphere or other hazardous environment.
The target should be switched o while charging. (Both lights o).
To Charge the Target:
!Note: Only use the
supplied charger.
1. Switch the target o and unscrew the charging socket cap on the
rear of the unit.
2. Connect the supplied mains charger (Part № 39-0033-2).
(Input: 100–240VAC, 50–60Hz, 1.5A Output: 24VDC, 2.5A, 60W).

User instrucons (in compliance with ATEX 94/9/EC Direcve, Annex II, 1.0.6)
Mini Target Part Numbers: 20-0108-1 and 20-0110-1
ATEX Certificate Number: SIRA 10ATEX2254X
Use in Hazardous Environments
XTargets may be used in zones 0, 1, or 2 with ammable gases.
XTargets may be used in the presence of ammable gases and vapours with
apparatus groups IIB or IIA and with temperature classes T1 or T2 or T3 or T4.
XThe equipment is cered for use in ambient temperatures in the
range of −25°C to +55°C and should not be used outside this range.
Installation and Maintenance
XTargets must be installed by suitably trained personnel in accordance
with the applicable code of pracce (typically IEC EN 60079-14).
XTargets must be inspected regularly by suitably trained personnel in accordance
with the applicable code of pracce to ensure they are maintained in a sasfactory condion.
XTargets are not intended to be repaired by the user. They must only be repaired or serviced by Guidance Navigaon Ltd,
or by an approved service representave of Guidance Navigaon Ltd, in accordance with the applicable code of pracce.
XTargets do not require assembly or dismantling.
They do not contain any customer-replaceable parts, and no user adjustment is required.
Electrostatic Hazard
XTargets must not be installed where external condions could cause an electrostac build-up on their outer casing.
XThe target’s outer casing presents a stac hazard and must only be cleaned using a damp cloth.
Corrosive Substances
XTargets should be protected from solvents, or acidic gases or liquids that may aect the integrity of its outer case.
Transport
XTargets must be transported in a suitable transit case.
Mini-Targets can be used with RadaScan and Mini-RadaScan systems.
One or more targets should be mounted on the target plaorm or vessel.
There are two models of Mini-Target:
XRechargeable (Part № 20-0108-1-S2-*)
XNon-rechargeable (Part № 20-0110-1-S2-*)
(The non-rechargeable variant requires baery pack replacement as roune
maintenance. This should be undertaken by Guidance Navigaon Limited,
or a suitably qualied service technician).
!Do not open the target. It should only be serviced by Guidance Navigaon
Limited, or a suitably qualied service technician.
If you experience any problems with the unit, please contact:

Mounting
The mini-target can be used with or without a swivel bracket, as long as
it is mounted with its longest side vercal, and its carrying-handle at the
top.
To Mount the Target:
1. Hook the foot of the target underneath the knob on the boom of
the mounng plate. (See right).
2. Rotate the target backwards unl it is held in place by its magnets
against the mounng plate.

Swivel Bracket
The swivel bracket (Part № 21-0275-1) should be used to point
the target towards the RadaScan vessels’ working area.
It can be mounted on either a horizontal or vercal bar:
Positioning
The locaon, range and orientaon of the targets in relaon to the sensor have a signicant eect on the tracking
performance of the RadaScan / Mini-RadaScan systems, and hence on the quality of the posion data sent to the DP system.
RadaScan is a radar-based system. Metallic structures reect the microwave beam transmied by the sensor,
and can cause mulpath interference, where ghost images are reported by the system. However, this unwanted
phenomenon can be prevented by carefully posioning the targets according to the following guidelines:
Targets Should be Mounted:
With a clear, unobstructed view towards the RadaScan-equipped vessel.
At a height no lower than two metres below the vessel-mounted Sensor.
At a height no higher than ve metres above the vessel-mounted Sensor.
On outside corners of the rig or plaorm to minimise the amount of metallic structure around them.
Good Location
Good angle of incidence.
Lower angle of elevaon allows vessel
to pick up target on approach.
Longer range aids performance
in high sea states.
Usually clear of obstrucons
and away from enclosed corners.
Provides adequate cover
during vessel manœuvres.
Rig/Plaorm RadaScan Vessel
Good Target
Locaons
Poor Location
Good angle of incidence.
Steep angle of elevaon prevents vessel from
picking up target on approach.
Shorter range inhibits performance
in high sea states.
Oen surrounded by obstrucons
and radar-reecng metalwork.
Does not provide adequate cover
during all vessel manœuvres.
Rig/Plaorm RadaScan Vessel

Targets Should NOT be Mounted:
On inside corners.
Below an overhang.
On lower service decks below a main-deck overhang.
