Precautions - Yamaha R100 Bedienungsanleitung

1. PRECAUTIONS
. 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.
. AVOID PHYSICAL SHOCKS
Strong physical shocks to the unit can cause damage.
Handle и with care.
. 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 person-
nel. Opening the case and/or tampering with the inter-
nal circuitry will void the warranty.
. MAKE SURE POWER IS OFF BEFORE
MAKING OR REMOVING CONNECTIONS
Always tum the power OFF prior to connecting or
disconnecting cables. This is important to prevent
damage to the unit itself as well as other connected
equipment.
. HANDLE CABLES CAREFULLY
Always plug and unplug cables — including the AC
cord — by gripping the connector, not the cord.
. 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.
. ALWAYS USE THE CORRECT POWER SUP-
PLY
The R100 should only be powered using the supplied
Yamaha PA-1C (or PA-1) AC Adaptor. The use of
other adaptors can cause serious damage to the R100.
Never use a cascade arrangement for the power supply
connection from other equipment.
. ELECTRICAL INTERFERENCE
Since the R100 contains digital circuitry, it may cause
interference and noise if placed too close to TV sets,
radios or similar equipment. If such a problem does
occur, move the R100 further away from the affected ·
equipment.
