1. BEFORE YOU BEGIN

Every OVAL product is thoroughly tested and inspected before shipment from our factory. 

When received, its appearance should be inspected for possible damage by rough handling during tran-

sit. First of all, thoroughly read the handling precautions described in this section. For topics other than 

those covered in this section, refer to the respective sections of this manual.

If at any time in the future you seek our assistance, contact the nearest sales office in your area.

1.1 Confirming the Nameplate

The  instrument  is  adjusted  to  individual  specifi-

cations  before  shipment  from  our  factory.  Model 

number appears on the nameplate attached to the 

top of the housing. 

Make sure to see that the instrument you received 

conforms to the General Specifications (pages 21 

through  24)  and  the  Product  Code  Explanation 

(pages 10 and 11).

When you inquire, supply complete infor-

mation  as  to  the  product  name,  model 
number,  product  number,  ratings,  and 
other pertinent information.

1.2 Transportation Precautions

(1) In order to safeguard against damage during transit, transport your instrument to the installation loca-

tion in the original package used for shipment from the factory if possible.

(2) Use care to avoid impact shocks to the instrument during transit.

1.3 Storage Precautions

If the instrument upon receipt is to be stored for extended periods of time before installation, unexpected 

problems could arise. If such is the case, the following considerations should be taken:

(1) The instrument can best be stored in the original package used for transit from the factory.

(2) The place of storage should meet the following requirements:

 Free from rain and water

 Free from vibration and impact shocks

 With minimal temperature and humidity variation (around 25

°

C and 65% R.H.)

EL4001 is the 

generic desig-

nation of the 

EL4001 series 

computers.
