Section 1
Service Overview
1-1. Cautions when Handling Hard Disk Drive (HDD)
The hard disk drives (HDD) are installed in the NSP-1.
The HDD is a precision part. The causes such as shock, vibration and static electricity to the unit, and the
conditions of temperature and humidity may damage HDD or its data.
Before servicing, read the following cautions carefully, and perform the servicing with extra care.
Cautions for Shock and Vibration
When placing on a floor or table
.Put a cushion*on a stable and horizontal place, and put the NSP-1 on it gently.
.Do not place the unit near vibrating equipment.
For the NSP-1 and HDD
.Never hit the HDD with a tool, or drop it on the NSP-1.
Take extra care
.Never give vibration or shock to the HDD while the power is on, or within about 30 seconds after
turning off the power.
*Cushion : Polyethylene foam (density : 38 kg/m3, surface intrinsic resistance : 1011 to 1012 Z, thickness : 50 mm ) or equivalent.
Cautions for Static Electricity
.Keep static-producing items such as plastics (air cap and others) away from the working area.
.When handling the HDD, it must be put on the earth-band to establish a ground.
Cautions for Temperature and Humidity
.Temperature and humidity of storage and operating conditions must be kept within the correct specified
range.
.Never turn on the power with the cabinet removed in consideration of the air-cooling effect.
But if the power needs to be turned on, it is essential that the unit should be covered with the substitute
for the cabinet.
Cautions when an Error Appears in HDD
.Treat the NSP-1 conform to the above cautions, even when an error has appeared.
.Keep the NSP-1 in the condition in which the error has appeared, and write down the details of the
error.

1-2 (E) NSP-1
Cautions for Operating Time
NSP-1 cannot be kept playing or receiving materials for 24 hours everyday.
It must be put to sleep mode once a day for 5 minutes.
The time for sleep mode can be set by the following procedures.
When using NSP-1
1. Refer to Section 1-8-2, and display the status page.
2. Click on the [User|Settings] of the status page, and set the time for sleep mode in “Break Time
From”.
