IMPORTANT SAFETY NOTICE

About Lead Free Solder (PbF)

Distribution of PbF PCB:

PCBs (manufactured) using lead free solder (PbF) will have a stamp on the PCB.

Caution:

8 Lead free solder has a higher melting point than standard solder. Typically the melting points is 35 °C – 40 °C

(95 °F – 104 °F) higher. Please use a soldering iron with temperature control and adjust it to 360 °C – 370 °C
(680 °F – 698 °F). In case of using high temperature soldering iron, please be careful not to heat too long.

8 Lead free solder will tend to splash when heated too high (600 °C / 1112 °F).
8 Lead free solder (Sn - 3.0Ag – 0.5Cu) or equivalents are recommended on repairing our lead free soldered PCB.

Y WARNING

This service information is designed for experienced repair technicians only and is not designed for use by the
general public.
It does not contain warnings or cautions to advise non-technical individuals of potential dangers in attempting to
service a product.
Products powered by electricity should be serviced or repaired only by experienced professional technicians. Any
attempt to service or repair the product or products dealt with in this service information by anyone else could
result in serious injury or death.

SAFETY PRECAUTIONS

GENERAL GUIDELINE

1. When service is required, observe the original lead
dress. Components, wires or cables that indicate
evidence of overheating or other electrical or mechanical
damage should be replaced.

2. After servicing see to that all the protective devices, such
as insulation tape, shields must be properly installed.

3. After servicing, make the following leakage current
checks to prevent the customer from being exposed to
shock hazards.

LEAKAGE CURRENT COLD CHECK

1. Unplug the AC cord and connect a jumper between the
two prongs on the plug.

2. Measure the resistance value, with an ohmmeter,
between the jumpered AC plug and each exposed
metallic cabinet part on the equipment such as
screwheads, connectors, control shafts, etc.
When the exposed metallic part has a return path to the
chassis, the reading should be between 1M Ω and 5.2M
Ω. When the exposed metal does not have a return path
to the chassis, the reading must be ∞ (infinity).
Any resistance value below this range indicates an
abnormality which requires corrective action.

3. Repeat the test with the AC switch in the "OFF" position.

LEAKAGE CURRENT HOT CHECK

1. Plug the AC cord directly into adaptor socket and plug
adaptor into the AC outlet. Do not use an isolation
transformer for this check.

2. Connect a 1.5k Ω/10W resistor, paralleled by 0.15 µF
capacitor, between each exposed metallic part on the
unit and a good earth ground such as a water pipe, as
shown in Figure 1.

3. Use an AC voltmeter, with 1000Ω/volt or more sensitivity,
to measure the potential across the resistor.

4. Check all exposed metallic parts of the cover (BNC
connector, Handle bracket, Metallic cabinet,
Screwheads, Metallic overlays, etc.), and measure the
voltage at each point.

5. Reverse the AC plug in the AC plug adaptor and re-peat
each of the above measurements.

6. The potential at any point should not exceed 0.75 V
RMS.
A leakage current tester (SIMPSON MODEL 229 or
equivalent) may be used to make the hot checks.
Leakage current must not exceed 0.5 milliampere.
In case a measurement is outside of the limits specified,
there is a possibility of a shock hazard, and corrective
action must be taken before returning the instrument to
the customer.

Important

• Changing the MODE switch will not be accepted when
the ERROR indicator lights red and/or when HDD 1-4
indicate a system error status by lighting red and
orange. When this happens, ask your dealer to solve
the error.

• When set to RAID5, the HDD preinstalled in the digital
disk recorder will not work. Instead, it is applied only to
the HDDs installed in the extension unit and the digital
disk recorder will perform storage and readout of the
image data by accessing the extension unit.

• The position of the MODE switch of all units in a system
must be the same.

• The available disk space of the unit can be logically cal­culated as follows. The actual space may be several
percent lower than you calculated depending on the
HDD type used and their combination. The most effi­cient way is to use the same type drives.

When SINGLE is selected, it will be the sum of all
the HDD sizes.
When RAID 5 is selected, it will be as follows.
When 3 HDDs are in the unit: It will be double the
size of the smallest HDD size.
When 4 HDDs are in the unit: It will be triple the size
of the smallest HDD size.

For example, if 4 HDDs of 80 GB, 120 GB, and two
160 GB are mounted, the available disk space will
be 80 G x 3 = 240 GB.

!5 HDD power switch [HDD POWER]

Use this switch in the ON position for normal operation.
ON: Supplies the power to the HDDs and the HDD

power indicators will light. Default position

OFF: Does not supply the power and the HDD power

indicators will go off.

!6 Recover button [RECOVER]

Use this button with the RESET button after replacing
HDDs used in the RAID 5 mode to start data recovery.
