PRECAUTIONS
■
USE THE CORRECT POWER SUPPLY
Power to the GW10 should be supplied only from the appropriate Yamaha
AC adaptor (the PA-3 or another adaptor specifically recommended by
Yamaha). Use of another adaptor may cause serious damage to the unit.
Also make sure that the adaptor you have is appropriate for the AC mains
supply voltage in the area where you intend to use the GW10. (The correct
input voltage is marked on the adaptor.)
■
MEMORY BACKUP
The GW10 contains a special long-life lithium battery that retains the
contents of the internal RAM memory even when the power is turned off.
The battery should last for approximately five years from the date of
manufacture. When the backup battery power becomes too low to maintain
the memory contents, the MEMORY/TUNER Indicator lights “L” then “o”
three times when the power is turned on.
When this happens, write down all necessary settings to a piece of paper
(or on copies of the chart provided on page 48), then have the battery
replaced by qualified Yamaha service personnel as soon as possible. DO
NOT ATTEMPT TO REPLACE THE BACKUP BATTERY YOURSELF!
(Keeping records of your original settings is necessary since the memory
contents cannot be preserved when the battery is changed.)
■
AVOID EXCESSIVE HEAT, HUMIDITY, DUST AND VIBRA-
TION
Keep the unit away from locations where it is likely to be exposed to high
temperatures (such as direct sunlight) or humidity. Also avoid locations
which are subject to excessive dust accumulation or vibration which could
cause mechanical damage.
■
AVOID PHYSICAL SHOCKS
Although the GW10 has been constructed to withstand the normal rigors of
stage and studio use for optimum sturdiness and reliability, avoid subject-
ing it to strong physical shocks (such as dropping or hitting it), since this
may damage the unit. Since the GW10 is a precision-made electronic
device, also avoid applying excessive force to the various controls.
■
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. Opening the case and/or tampering in
any way with the internal circuitry will void the warranty.
■
MAKE SURE POWER IS OFF BEFORE MAKING OR REMOV-
ING CONNECTIONS
Always turn the power off prior to connecting or disconnecting cables.
■
HANDLE ALL CONNECTIONS CAREFULLY
Always be careful to connect and disconnect all cables and cords by
gripping the connector itself, not by pulling on the cord.
