Warnings
CAUTION: To r educe the risk of electrical shock, do not remove the cover. No user serviceable parts inside;
refer servicing to qualified personnel. To change the operating voltage or change the firmware EPROM, it is
necessary to remove the cover of the unit. As a result, such operations must be carried out only by technicallyqualified personnel.
WARNING: To reduce the risk of fire or electrical shock, do not expose this appliance to rain or moisture.
This symbol, wherever it appears, alerts you to the presence of uninsulated dangerous voltage inside
the enclosure—voltage that may be sufficient to constitute a risk of shock. Operations indicated with
this symbol should be carried out only by technically-qualified personnel.
This symbol, wherever it appears, alerts you to important operating and maintenance instructions in
the accompanying literature. Read the manual.
Environmental warnings
• Never touch the AC plug with wet hands.
• Do not use this unit in damp areas or near water.
•Avoid damaging the AC plug or cord and potentially causing a shock hazard.
• If liquids spill into or onto the DA-16, disconnect the power and return to your dealer for servicing.
• This unit should only be connected to an AC power supply of the correct voltage. Check with your dealer
if in doubt.
•Precautions should be taken so that the grounding or polarization of the AC power is not defeated.
• Unplug the AC cord when the unit is unused for long periods of time.
• This unit should only be cleaned as recommended by the manufacturer, or damage to the finish may result.
•To avoid potential damage to your unit, only use in areas where proper ventilation and moderate temperatures are assured.
Power warning
AC voltage ratings for electrical power vary from area to area. Severe damage to your unit is possible
if your DA-16 is configured incorrectly for your local power. If in doubt, consult an Apogee dealer. A
label adjacent to the power connector indicates the voltage to which the unit was set on leaving the
factory.
Instructions for changing the power input voltage are provided. We strongly advise you to check that
the voltage label remains current and is updated if the input voltage setting is changed.
FCC warning
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against
harmful interference when operated in a commercial environment. This equipment generates, uses,
and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area
is likely to cause harmful interference, in which case the user will be required to take whatever measures may
be required to correct the interference at his own expense.

APOGEE ELECTRONICS CORPORATION warrants this product to be free of defects in material and manufacture under normal use for a period of 12 months. The term of this warranty begins on the date of sale to the
purchaser. Units returned for warranty repair to Apogee or an authorized Apogee warranty repair facility will be
repaired or replaced at the manufacturer’s option, free of charge. All units returned to Apogee or an autho-
rized Apogee repair facility must be prepaid, insured and properly packaged. Apogee reserves the right to
change or improve design at any time without prior notice. Design changes are not implemented retrospectively, and the incorporation of design changes into future units does not imply the availability of an upgrade
to existing units.
This warranty is void if Apogee determines, in its sole business judgment, the defect to be the result of abuse,
neglect, alteration or attempted repair by unauthorized personnel.
The warranties set forth above are in lieu of all other warranties, expressed or implied, and Apogee specifically disclaims any and all implied warranty of merchantability or of fitness for a particular purpose. The buyer
acknowledges and agrees that in no event shall the company be held liable for any special, indirect, incidental
or consequential damages, or for injury, loss or damage sustained by any person or property, that may result
from this product failing to operate correctly at any time.
USA: Some states do not allow for the exclusion or limitation of implied warranties or liability for incidental or
consequential damage, so the above exclusion may not apply to you. This warranty gives you specific legal
rights, and you may have other rights which vary from state to state.
Service Information
If the AD-16 is kept in a clean environment free of excess dust, moisture and heat, it will give years of trouble-free service.
The AD-16 contains no user-serviceable components: refer to qualified service personnel for repair or upgrade.
Your warranty will be voided if you tamper with the internal components. If you have any questions with regard
to the above, please contact Apogee.
In the event your AD-16 needs to be upgraded or repaired, it is necessary to contact Apogee prior to shipping,
and a Return Materials Authorization (RMA) number will be assigned. This number will serve as a reference for
you and helps facilitate and expedite the return process. Apogee requires that shipments be pre-paid and
insured — unless otherwise authorized in advance. IMPORTANT: Any shipment that is not pre-paid or is sent
without an RMA number will not be accepted.
