PRECAUTIONS
1. Avoid Excessive Heat, Humidity, Dust and
Vibration
Keep the unit away from locations where it is likely to be
exposed to high temperatures or humidity — such as near
radiators, stoves, etc. Also avoid locations which are subject
to excessive dust accumulation or vibration which could cause
mechanical damage.
2. Avoid Physical Shocks
strong physical shocks to the unit can cause damage. Handle
it with care.
3. Do Not Open The Case Or Attempt Repairs
Or Modifications Yourself
This product contains no user-serviceable parts. Refer all
maintenance to qualified Yamaha service personnel. Open¬
ing the case and/or tampering with the interna! circuitry will
void the warranty.
4. Make Sure Power Is Off Before Making Or
Removing Connections
Always turn the power OFF prior to connecting or discon¬
necting cables. This is important to prevent damage to the
unit itself as well as other connected equipment.
5. Handie Cables Carefully
Always plug and unplug cables ™ including the AC cord —
by gripping the connector, not the cord.
6. Clean With a Soft Dry Cloth
Never use solvents such as benzine or thinner to clean the
unit. Wipe clean with a soft, dry cloth.
7. Always Use the Correct Power Supply
Make sure that the power supply voltage specified on the
rear panel matches your local AC mains supply. Also make
sure that the AC mains supply can deliver more than enough
current to handle all equipment used in your system.
