Akai EWI 1000 User Manual

* SAFETY INSTRUCTIONS
PRECAUTIONS DURING SERVICING
1. Parts identified by the A symbol are critical for safety.
,^ Replace only with parts number specified.
2. 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.
3. Use specified internal wiring. Note especially:
1) Wires covered with PVC tubing
2) Double insulated wires
3) High voltage leads
4. 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)
5. When replacing AC primary side components (transform
ers, power cords, noise blocking capacitors, etc.), wrap
ends of wires securely about the terminals before soldering.
6. Observe that wires do not contact heat producing parts
(heatsinks, oxide metal film resistors, fusible resistors,
etc.).
• INFORMATION
7. Check that replaced wires do not contact sharp edged or
pointed parts.
8. Also check areas surrounding repaired locations.
9. Use care that foreign objects (screws, solder droplets, etc.)
do not remain inside the set.
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 M ohms, but for equipment with external
antenna terminals (tuner, receiver, etc.) and is intended for
[C] or [X] , specified insulation resistance should be head
phone jacks, line-in-out jacks, etc. more than 2.2 M ohms
(ground terminals, microphone jacks).
PRECAUTIONS FOR LITHIUM BATTERY
The lithium battery may explode when heated excessively.
[OBSERVE THE FOLLOWING WHEN REPLACING]
• replace with the same make and type only.
• Use soldering iron in "recommended way" only.
• Place battery in correct polarity.
• Do not short the terminals.
• Do not recharge battery.
• Do not dispose of battery in fire.
