Unpacking

Unpacking

Although your EQ-2231A 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 to 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.

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.
