Unpacking

Unpacking

Although your MA-106A is neither complicated nor difficult to operate, we recommend you take a few minutes
to  read  this  brief  manual  and  familiarize  yourself  with  the  important  information  regarding  product  features,
setup and operation.

As with most electronic devices, we strongly recommend you retain the original packaging. In the unlikely event
the product must be returned for servicing, the original packaging (or reasonable equivalent) is required.

Installation

Environment

Never  place  this  product  in  an  environment  which  could  alter  its  performance  or  reduce  its  service  life.  Such
environments usually include high levels of heat, dust, moisture, and vibration.

IMPORTANT SAFETY INSTRUCTIONS

1.  Read these instructions.
2.  Keep these instructions.
3.  Heed all warnings.
4.  Follow all instructions.
5.  Do not use this apparatus near water.
6.  Clean only with dry cloth.
7.  Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
8.  Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including

amplifiers) that produce heat.

9.  Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades

with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide
blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult
an electrician for replacement of the obsolete outlet.

10. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and

the point where they exit from the apparatus.

11. Only use attachments/accessories specified by the manufacturer.
12. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus.

When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.

13. Unplug this apparatus during lightning storms or when unused for long periods of time.
14.  Refer  all  servicing  to  qualified  service  personnel.  Servicing  is  required  when  the

apparatus  has  been  damaged  in  any  way,  such  as  power-supply  cord  or  plug  is
damaged,  liquid  has  been  spilled  or  objects  have  fallen  into  the  apparatus,  the
apparatus  has  been  exposed  to  rain  or  moisture,  does  not  operate  normally,  or  has
been dropped.
