Optional DIMM Installation

This section explains how to install DIMM memory modules to the DTXTREME III.

Installation Precautions

WARNING

• Before beginning installation, switch off the power to the instrument and connected peripherals, and unplug them from the power outlet. Installation or removal of any devices should be started ONLY after the instrument (and the optional hardware) returns to normal room temperature.

Then remove all cables connecting the instrument to other devices.

(Leaving the power cord connected while working can result in electric shock. Leaving other cables connected can interfere with work.)

• Be careful not to drop any screws inside the instrument during installation. (This can be prevented by keeping the optional units and cover away from the instrument while attaching). If this does happen, be sure to remove the screw(s) from inside the unit before turning the power on.

Loose screws inside the instrument can cause improper operation or serious damage. If you are unable to retrieve a dropped screw, consult your Yamaha dealer for advice.

• Install the optional units carefully as described in the procedure below.

Improper installation can cause shorts which may result in irreparable damage and pose a fire hazard.

• Do not disassemble, modify, or apply excessive force to board areas and connectors on optional units. Bending or tampering with boards and connectors may lead to electric shock, fire, or equipment failures.

CAUTION

• It is recommended that you wear gloves to protect your hands from metallic projections on optional units and other components. Touching leads or connectors with bare hands may cause finger cuts, and may also result in poor electrical contact or electrostatic damage.

• Be careful of static electricity. Static electricity discharge can damage the IC chips on the DIMM. Before you handle the optional DIMM, to reduce the possibility of static electricity, touch unpainted metal parts or a ground wire on the devices that are grounded.

• Handle the optical units with care. Dropping or subjecting them to any kind of shock may cause damage or result in a malfunction.

• Do not touch the exposed metal parts in the circuit board. Touching these parts may result in a faulty contact.

• Be careful not to misplace any of the screws.

• Do not use any screws other than what are installed on the instrument.

Use of incorrect screws can cause damage.

DIMM Type and DIMM Configuration

• Yamaha recommends that you purchase DIMMs that conform to the JEDEC* standard. Please be aware, however, that conformance to this standard does not constitute a guarantee that the DIMMs will operate correctly on the DTXTREME III.

* JEDEC (Joint Electron Device Engineering Council) sets standards for terminal configurations within electronic devices.

• Use only 168-pin DIMMs of 64, 128 or 256 MB capacity (synchronized DRAM; PC100 or PC133).

• When installing DIMMs, make sure to install them in a matched pair of the same capacity. You cannot install only one module and leave the second memory socket open. Also make sure each DIMM in the pair is of the same manufacturer and the same type. DIMMs of different makers and configurations may not work together.

• When purchasing DIMMs, make sure that the DIMM design does not utilize more than 18 memory chips per module. (DIMMs comprised of more than 18 chips do not operate correctly on the DTXTREME III.)

64MB x 2 = 128MB 128MB x 2 = 256MB

256MB x 2 = 512MB

Compatible DIMMs

The DTXTREME III does not necessarily support all commercially available DIMMs. Yamaha cannot guarantee operation of DIMMs that you purchase.

Before purchasing DIMMs, please consult your Yamaha dealer, or an authorized Yamaha distributor (see list at end of the Owner’s Manual) for advice, or visit the following website: http://www.yamaha.co.jp/english/product/drums/ed/

DIMM Installation

1

Turn the DTXTREME III power off, and disconnect the power cord.

4

Insert the two DIMMs into the DIMM sockets.

2

Turn over the DTXTREME III so you can have direct access to the underside.

To protect the data dial and sliders from damage, place the

DTXTREME III so the four corners are supported by something that provides sufficient support, such as magazines or cushions. Place supports at all four corners, taking care not to touch the Data dial and Sliders.

Installing the DIMM modules to the sockets

Make sure that the DIMM module is aligned correctly before you install it.

IMPORTANT

Keep the removed screws in a safe place. They will be used when re-attaching the cover to the instrument after installing the DIMMs.

Confirm whether or not both the levers are firmly locked.

5

Re-install the cover you removed in step 3, in reverse order.

NOTE

• When you re-install the cover, make sure to steady the cover from the side with your hand.

Removing DIMMs

1

Press the ejector lever until the DIMM unlocks.

6

Check that the installed DIMMs are functioning properly.

Set the DTXTREME III right-side up, and connect the AC power adaptor to the DC IN jack of the DTXTREME III and an AC wall outlet.

Turn on the power, go to the Sampling mode by pressing the

[SAMPLING] button, then press the [SF6] INF button (page

136). If the DIMMs have been installed properly, the appro-

priate available memory size is indicated in the display.

Pull the DIMM vertically out of the socket.

NOTE

• If the DIMMs have not been installed properly, the Sampling function will not work correctly. If this occurs, turn the power off, perform the instructions above again, and make sure to install the DIMMs firmly.
