TYROS Owner’s Manual
This section contains information about setting up your TYROS and preparing to play. Be sure to read through this 
section carefully before turning the power on. 
1 Make sure the POWER ON/OFF switch on the TYROS is set 
to OFF.
2 Connect the supplied power cord to the AC INLET terminal 
on the instrument’s rear panel.
3 Connect the other end of the power cord to an AC outlet. 
Make sure your TYROS meets the voltage requirement for 
the country or region in which it is being used.
Since the TYROS has no built-in speakers, you’ll need to use an external speaker system — such 
as the optional TRS-MS01, which is designed specifically for the TYROS. For instructions on 
installing the TRS-MS01 to the TYROS, see page 160.
Power Supply
• Make sure your TYROS is rated for the AC 
voltage supplied in the area in which it is to 
be used (as listed on the rear panel). Con-
necting the unit to the wrong AC supply can 
cause serious damage to the internal cir-
cuitry and may even pose a shock hazard!
• Use only the AC power cord supplied with 
the TYROS. If the supplied cord is lost or 
damaged and needs to be replaced, contact 
your Yamaha dealer. The use of an inappro-
priate replacement can pose a fire and shock 
hazard!
• The type of AC power cord provided with the 
TYROS may be different depending on the 
country in which it is purchased (a third 
prong may be provided for grounding pur-
poses).
Improper connection of the grounding con-
ductor can create the risk of electrical shock. 
Do NOT modify the plug provided with the 
TYROS. If the plug will not fit the outlet, have 
a proper outlet installed by a qualified electri-
cian. Do not use a plug adapter which 
defeats the grounding conductor.
