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:

8Lead 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.

8Lead free solder will tend to splash when heated too high (600 °C / 1112 °F).

8Lead free solder (Sn - 3.0Ag – 0.5Cu) or equivalents are recommended on repairing our lead free soldered PCB.

YWARNING

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 Ωand 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 cal-

culated as follows. The actual space may be several

percent lower than you calculated depending on the

HDD type used and their combination. The most effi-

cient 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.
