PRECAUTIONS — TAKING CARE OF YOUR PORTASOUND
SE a I eT CSET ST
Your new PortaSound is a fine musical instrument — and should be treated as such.
Handle it with care and common sense, and it will give you years of enjoyment.
e Location
Avoid exposure to direct sunlight or other sources of heat.
Never leave it inside a car where it can get very hot. Vi-
bration, excessive dust, cold, low or high humidity can
also cause malfunction.
e@ Handling
Avoid rough handling. Don't drop or jolt the PortaSound
as this can damage the internal circuitry. Pressing too
hard on keys or controls may lead to malfunctions. When
cords are plugged into the rear panel jacks, pay particular
attention not to apply excessive force to them since this
may damage the terminals.
e Adaptors
Use only the power adaptor described in the POWER
section. Disconnect the AC adaptor when not using your
PortaSound.
e Batteries
+ When not using your PortaSound for long periods, be
sure to remove the batteries to avoid damage through
battery leakage.
* Replace weak batteries before they run down com-
pletely.
- Always replace all batteries with new ones.
- Do not use different kinds of batteries at the same time.
«In case electrolyte has leaked into the battery com-
partment, wipe it off completely before installing new
batteries.
+ Never disassemble, heat or throw discarded batteries
into a fire. Dispose of them properly.
e@ Cleaning
Clean the exterior with a soft, dry cloth. Using chemical
solvents will damage the finish.
Interference Through Electromagnetic Fields
Do not use your PortaSound close to television sets or
other equipment receiving electromagnetic signals as this
could cause interference noise in the other appliance.
Service and Modifications
Your PortaSound contains no user serviceable parts.
Opening it or tampering with it in any way can lead to
electrical shock as well as damage. Of course, any resulting
damage will no longer be repaired free of charge. Refer
all servicing to qualified YAMAHA personnel.
