PACKING

02.01

When a STRATA

system

examine

all

packages

and

make

careful

note

any visible

damage.

If any

damage

is found, bring

the

attention

the

delivery

rier

and make

the

proper

claims.

02.02

Check

the

STRATA

determined

that

any

that

any

equipment

contact

your

Toshiba

supplier

immediately.

02.03

After

unpacking

(before

in-

stallation

started),

inspect

all

equip-

ment for damage. If any damage is

detected,

contact

your

delivery

carrier

immediately. If possible,

retain

all

original

packing

material.

02.04

When

handling

(installing,

re-

moving, examining,

etc.)

cir-

cuit

board,

not

touch

Always hold a PCB by

its

edge.

02.05

When

packing

storing

the

CRDU

and/or

ensure

the

fol-

lowing:

•

not use

plastic

or any

type

conductive

material

for

packing

either

the

CRDU

MCCU.

• Use plain

paper.

NOTE:

Conductive

may

cause

battery

discharge

and

damage
