SAFETY SUMMARY

The following general safety precautions must be observed during all phases of operation, service, and repair of this unit. Failure to comply with these precautions or with specific warnings elsewhere in these instructions violates safety standards of design manufacture and intended use of this unit. Lexicon, Inc. assumes no liability for failure to comply with these requirements.

GROUND THE INSTRUMENT

To minimize shock hazard, the unit chassis and cabinet must be connected to an electrical ground. The unit is equipped with a threeconductor AC power cable. The power cable must be either plugged into an approved three-contact electrical outlet or used with a threecontact to two-contact adapter with the grounding wire (green) firmly connected to an electrical ground (safety ground) at the power outlet. The power jack and mating plug of the power cable meet International Electrotechnical Commission (IEC) safety standards.

Do not operate the unit in the presence of flammable gasses or fumes. Operation of any electrical instrument in such an environment constitutes a definite safety hazard.

KEEP AWAY FROM LIVE CIRCUITS

Operating personnel must not remove unit covers. Component replacement and internal adjustments must be made by qualified maintenance personnel. Do not replace components with power cable connected. Under certain conditions, dangerous voltages may exist even with the power cable removed. To avoid injuries, always disconnect power and discharge circuits before touching them.

DO NOT SERVICE OR ADJUST ALONE

Do not attempt internal service or adjustment unless another person capable of rendering first aid resuscitation is present.

DO NOT SUBSTITUTE PARTS OR MODIFY INSTRUMENT

Because of the danger of introducing additional hazards, do not install substitute parts or perform any unauthorized modification to the unit.

ELECTROSTATIC DISCHARGE

(ESD) PRECAUTIONS

CAUTION

The following practices minimize possible damage to ROMs resulting from electrostatic discharge or improper insertion.

•Keep parts in original containers until ready for use.

•Avoid having plastic, vinyl, or Styrofoam in the work area.

•Wear an anti-static wrist strap.

•Discharge personal static before handling devices.

•Remove and insert boards with care.

•When removing boards, handle only by non-conductive surfaces and never touch open-edge connectors except at a static-free workstation.*

•Minimize handling of ROMs.

•Handle each ROM by its body.

•Do not slide ROMs or boards over any surface.

•Insert ROMs with the proper orientation, and watch for bent pins on ROMs.

•Use anti-static containers for handling and transport.

*To make a plastic-laminated workbench anti-static, wash with a solution of Lux liquid detergent, and allow to dry without rinsing.

PRESERVING USER BANK PROGRAMS & SYSTEM SETTINGS

User Bank programs will be preserved during the software installation process. But, to avoid accidental initialization of User Bank programs and other system settings, it is recommended to dump system information to an external MIDI storage device before installing the new software. To do this, refer to the instructions that begin at the top of the next column.

If desired, follow the instructions that begin below to perform MIDI dumps of system information and User Bank programs:

1.Connect a 5-pin MIDI cable from the MPX G2 to an external MIDI storage device. This cable should be connected from the MIDI OUT connector on the MPX G2 to the MIDI IN connector on the external MIDI device.

2.Press the front panel System button to enable System Mode. The front panel display will appear as shown in the figure below.

System select:

Audio

3.Rotate the front panel selection knob two clicks to the right, until the MIDI option is selected as shown in the figure at the top of the next page. The selection knob is located to the right of the Effect buttons.

4.Before proceeding to Step 2: Install the ROM:

A.Put on the anti-static wrist strap.

B.Attach the copper tape to the MPX G2 chassis.

STEP 2: INSTALL THE ROM

1.Refer to the figure below to locate the ROM on the MPX G2 main board (location U93).

	POWER SUPPLY
ROM U93	PIN 1
	ROM

2.Examine the ROM provided in the upgrade kit. Because the manufacturing process leaves the pins angled out slightly from the ROM body, the pins must be straightened before insertion.

To straighten the pins:

A.Place the ROM on its side on a static-free, flat surface. See page 3 for instructions to create a static-free workstation.

B.Hold the body of the ROM. Gently exerting pressure downward, roll the ROM back and forth to force both rows of pins into a position parallel to the workstation. This is demonstrated in the figure below.

. . . Step Two: Install the ROM continues on page 10
