by

one

or

more

of

the

following

measures:

a)

Reorient

or

relocate

the

receiving

antenna.

b)

Increase

the

separation

between

the

equipment

and

the

receiver.

c)

Plug

the

equipment

into

a

different

□

Using

this

manual

Before

actually

using

the

DA-88,

please

read

this

manual

thoroughly

at

least

once,

so

you

will

know

where

to

return

when

you

need

answers.

Even

though

a

quick

glance

will

get

you

going,

careful

study

will

ensure

that

misunderstandings

won't

slow

you

down.

Use

of

capital

letters

:

In

general,

we

use

all

upper

case

type

to

designate

a

particular

switch,

or

as

in

:

and

4

Precautions

and

Recommendations

□

Environmental

conditions

The

DA-88

may

be

used

in

most

area,

but

to

maintain

top

performance

and

prolong

operating

life,

observe

the

following

environmental

limitations

:

1)

Nominal

temperature

should

be

5

to

35

degrees

Celsius

(41

to

95

degrees

Fahrenheit).

2)

Relative

humidity

should

be

30

to

90%

(non¬

condensing).

3)

Strong

magnetic

fields

should

not

exist

nearby,

o

Install

the

unit

in

an

area

with

proper

ventilation.

Beware

of

Condensation

:

When

the

DA-88

is

moved

from

a

cold

to

a

warm

place

or

used

after

sudden

temperature

change,

there

is

the

danger

of

condensation

;

water

vapor

in

the

air

could

condense

on

the

internal

mechanism,

making

correct

operation

impossible

and

causing

damage

to

the

tape.

If

condensation

occurs,

and

you

attempt

to

load

a

tape,

this

will

automatically

be

ejected.

To

prevent

this,

if

you

are

going

to

use

the

unit

in

a

condition

where

condensation

could

occur,

leave

the

unit

for

1

or

2

hours

with

the

power

turned

on,

then

turn

the

power

off

before

turning

it

on

again.

Do

the

same

when

condensation

has

occurred

too.

□

Recommended

tapes

The

DA-88

transport

mechanism

is

aligned

prior

to

shipment

for

SONY

Hi8

tapes

(MP

and

ME)

to

provide

optimum

recording

and

playback

performance.

As

of

October

1993

the

following

brands

and

types

of

Hi8

tape

have

proved

satisfactory

in

operation.

TASCAM

cannot

assume

responsibility

for

problems

which

may

arise

from

inconsistencies

in

tape

or

shell

manufacturing

quality.

Frequent

illumination

of

the

DA-88

ERROR

LED

may

indicate

the

possible

presence

of

tape-

related

dropouts.

Should

this

occur

we

recommend

that

the

tape

in

use

be

changed

before

recording

continues.

CAUTION

Never

use

tapes

longer

than

120-minute

tape

of

NTSC

(P6-120,

E6-120)

or

90-minute

tape

of

PAL/SECAM

(P5-90,

E5-90).

Also

never

use

tapes

which

have

been

used

previously

for

video

recording.

o

The

DA-88

senses

the

thickness

of

tapes

inserted,

and

if

you

attempt

to

load

longer

tapes

than

P6-150/E6-150

(NTSC)

or

P5-120/E5-120

(PAL/SECAM),

they

will

automatically

be

ejected.

□

Available

time

When

used

with

the

DA-88,

Hi8

video

tapes

provide

different

record/play

times

depending

on

whether

they

are

designed

for

the

NTSC

or

the

system,

and

therefore

□

Cleaning

the

heads

After

long

periods

of

use,

the

heads

may

become

dirty.

They

should

be

cleaned

after

every

50

hours

(or

so)

of

operation.

Be

sure

to

use

a

dry

cleaning

tape

designed

for

8

mm

video.

First,

if

the

machine

is

turned

on,

turn

it

off.

1.

Press

and

hold

both

the

▲

and

▼

keys

and

press

the

POWER

switch.

"CLEAning"

will

flash

in

the

display

to

indicate

that

the

machine

is

put

into

Cleaning

mode.

2.

Insert

your

cleaning

tape.

Cleaning

will

start

and,

about

15

seconds

later,

the

tape

will

automatically

be

ejected,

the

machine

quitting

the

cleaning

mode.

o

You

cannot

let

the

cleaning

tape

run

by

means

of

any

transport

control

buttons.

Never

try

to

rewind

it

for

reuse

by

any

means.

Use

a

new

cleaning

tape

only

once

thru,

o

Excessive

cleaning

causes

premature

wearing

of

the

heads.

Don’t

repeat

cleaning

5

times

or

more

at

a

stretch,

o

To

maintain

performance

of

the

machine,

besides

head

cleaning

(50

hours),

a

routine

maintenance

check

is

recommended

approximately

every

500

hours.

□

Others

o

To

avoid

electric

shock

or

other

accidents,

don't

open

the

unit

to

clean

inside

or

perform

internal

adjustments.

The

user

should

not

attempt

at

any

servicing

which

is

not

contained

in

this

Owner's

Manual,

o

Before

turning

off

the

unit,

be

sure

to

remove

the

tape

from

the

unit.

Leaving

it

in

the

unit

for

a

long

time

could

cause

damage

to

the

tape,

o

Don't

cut

tapes

for

any

editing

purposes.

Such

tapes

could

make

correct

operation

impossible

or

Toggles

two

When

you

have

to

select

depending

on

the

applications.

During

the

which

the

was

made,

and

either

of

the

two

LEDs

A

T

key

To

format

a

tape

is

to

record

it

with

subcode

data,

of

which

ABS

(absolute)

time

is

one.

This

ABS

data

express

the

elapsed

time

from

the

beginning

of

the

tape,

not

from

any

optionally

selectable

intermediate

point

:

hence

the

name

’’absolute.”

Formatting

a

tape

erases

whatever

is

previously

recorded

on

it.

To

prevent

formatting

from

starting

accidentally,

the

FORMAT

key

is

not

actually

activated

unless

you

press

it

twice.

IMPORTANT

Audio

can

be

recorded

while

formatting.

But

it's

wise

of

you

to

format

the

tape

from

the

beginning

all

the

way

to

the

end

before

recording

audio.

This

insures

against

noise

and

discontinuity

of

absolute

time

data.

If

you

want

to

record

audio

and

format

a

tape

at

one

time,

don’t

stop

recording

by

stopping

the

tape

with

STOP

or

PLAY.

Press

REC

which

allows

the
