Section 1 – Introduction to the DA-98

ing progresses. Since this monitoring is not syn-
chronized exactly with the source inputs, gapless
punch-in and punch-out is not possible in confi-
dence mode. For full details of confidence moni-
toring, together with other monitoring modes
available on the DA-98, see 7, “Monitoring
modes”.
1.4.3 Environmental conditions
The DA-98 can be operated in most environments,
but we suggest that you keep the environmental
conditions within the following limits:
Ambient temperature between 5° and 35° C (41°
and 95° F).
Relative humidity should be between 30% and
80% non-condensing
There should be no strong magnetic fields (speak-
ers, etc.) near the DA-98.
Avoid spraying polish, insecticides, etc. near the
DA-98.
Avoid subjecting the DA-98 to jolts, sudden
shocks, etc.
TASCAM does not accept responsibility for dam-
age resulting from neglect or accident.
1.4.4 Installing the DA-98
The DA-98 may be installed in a standard 19”
rack, occupying 4U of space. Since the DA-98 is
quite heavy (around 11kg – 24lb), your rack
should be strong and stable to take the weight of
the DA-98.
Optional rack mount adaptor handles (RM-98) are
available. For details, see 15.1.1, “RM-98 Rack
Mount Adaptor”.
The DA-98 should be mounted with the front
panel vertical.
1.4.5 Electrical considerations
Make sure that your local power supply matches
the voltage requirements marked on the rear panel
of the DA-98.
If you are in any doubt concerning the local power
supply, consult an electrician.
Avoid extreme voltage fluctuations. If necessary,
use an input voltage regulator to smooth the power
supplied to the DA-98.
Do not open the unit to clean inside, or to perform
any internal adjustments. You should not attempt
any cleaning or other maintenance procedures
which are not described in this manual.
You may need to clean the heads occasionally.
The procedure for doing this, and for checking
tape error rates, etc., is given in 14, “Maintenance
and memory setups”.
1.4.6 Condensation
If you use the DA-98 in a warm place after mov-
ing it from a cold place (for instance, recording on
location), or if there has been a sudden change in
temperature, condensation may occur within the
tape mechanism, with a risk of possible damage to
the unit.
WARNING
If you need to clean the DA-98, use a soft cloth, moist-
ened if necessary with a little detergent and water. Do
not use abrasive cleaners or solvents such as alcohol or
thinner.
WARNING
If you have to return the unit for service or repair, use
the original packing materials if possible. If the unit is to
be transported to a recording location, etc., use a suit-
able transport case with sufficient shock protection.
