SAFETY CHECK AFTER SERVICING

Confirm the specified insulation resistance between power cord plug prongs and externally exposed parts of the set is greater than 10 Mohms, but for equipment with external antenna terminals (tuner, receiver, etc.) and is intended for C or A, specified insulation resistance should be more than 2.2 Mohms (ground terminals, microphone jacks, headphone jacks, line-in-out jacks etc.)

PRECAUTIONS DURING SERVICING

1. Parts identified by the symbol parts are critical for safety.

Replace only with parts number specified.

1. In addition to safety, other parts and assemblies are specified for conformance with such regulations as those applying to spurious radiation. These must also be replaced only with specified replacements.

Examples: RF converters, tuner units, antenna selector switches, RF cables, noise blocking capacitors, noise blocking filters, etc.

1. Use specified internal wiring. Note especially:

1) Wires covered with PVC tubing
2) Double insulated wires
3) High voltage leads

1. Use specified insulating materials for hazardous live parts. Note especially:

1) Insulation Tape
2) PVC tubing
3) Spacers (Insulating Barriers)
4) Insulation sheets for transistors
5) Plastic screws for fixing microswitch (especially in turntable)

1. When replacing AC primary side components (transformers, power cords, noise blocking capacitors, etc.), wrap ends of wires securely about the terminals before soldering.

1. Observe that wires do not contact heat producing parts (heatsinks, oxide metal film resistors, fusible resistors, etc.).
2. Check that replaced wires do not contact sharp edged or pointed parts.
3. Also check areas surrounding repaired locations.
4. Use care that foreign objects (screws, solder droplets, etc.) do not remain inside the set.
5. The LITHIUM BATTERY employed for memory back up has an explosive probability when the battery itself is excessive heated.

Normally, LITHIUM BATTERY is not necessary to replace, because the life of LITHIUM BATTERY is about 10 years.

IN CASE OF REPLACING: RESOLDER AND SOLDER AS RECOMMENDED WAY.

Recommended way

VOLTAGE CONVERSION

Models for Canada, USA and Japan are not equipped with this facility. Each machine is preset at the factory according to its destination, but some machines can be set to 220V or 240V as required.

If the machine's Voltage can be converted:

Before connecting the power cord, set the VOLTAGE SELECTOR on the bottom panel for the correct Voltage is indicated.

SECTION 4

SERVICE BULLETIN

This section describes the information on techniques revisions and troubleshooting for servicing and adjusting AX60.
To maintain the performance of AX60, see also AX60 Service Manual for servicing and adjustment.
Further technical information will be issued as any arises. Keep such information carefully under the name of this file.

001 Subject: To improve performance

The ROM IC program has been changed to improve the following points.

1. AUTO TUNE request by MIDI is recognized but is not transmitted.
2. AUTO MUTE request by AUTO MUTE button is accepted up to 6 times causing other functions inoperative for up to 30 - 35 seconds.
3. When VERIFY is executed and the data recorded on the tape and that of AX60 is different whatever the reason may be, the data in AX60 may be re-written when PROTECT switch is off.
4. Since the position of PITCH BEND setting VR is memorized when the unit is turned off, when the unit is turned on again after changing the position of setting VR, the amount of Pitch Bend effect is different from its VR position.
5. In SPLIT mode, the MIDI channels are set for Upper keys and Lower Keys separately. But even after SPLIT mode is released, MIDI channels are not caceled thus AX60 accepts 2 MIDI channels.
