1
Ensure that the [1] (Power) switch on the 
rear panel is set to the Off ( /) position.
2Insert the appliance end of the bundled 
power cord (see below) into the [AC IN] jack, 
also on the rear panel.
3Plug the other end of the power cord into a 
domestic-use, AC wall outlet.
NOTECarry out this procedure in reverse order when 
disconnecting the power cord.
WARNING
Use only the AC power cord supplied with your stage piano. 
The use of an inappropriate replacement can lead to 
overheating or electric shock.
WARNING
The power cord supplied with your stage piano must not be 
used with other electrical equipment. Failure to observe this 
precaution can result in the equipment being damaged or 
lead to the outbreak of fire.

Setting Up
Connecting Audio 
Equipment
Your stage piano does not come with built-in speakers. In 
order to hear what you play, therefore, you will need to 
connect it to other audio eq uipment such as amplifiers 
and speakers. You can also plug a set of headphones 
into the [PHONES] jack in order to monitor the sound 
directly. Audio equipment can be connected in a number 
of different ways, two of which are described below. 
Based on the illustrations, choose the connection format 
most suited to your setup.
CAUTION
To prevent hearing loss, avoid using headphones at high 
volumes for extended periods of time.
NOTICE 
Whenever connecting other audio equipment, ensure that all 
devices are turned off.
Output via amplifiers or powered 
speakers
Using a pair of keyboard amplifiers or powered speakers, 
you can accurately reproduce the full richness of your 
stage piano’s Performances  (page 21) and effects, 
including stereo panning. In  this type of situation, 
connections to the amplifiers  or speakers should be 
made via the UNBALANCED [L/MONO] and [R] OUTPUT 
jacks on the rear panel. If you would prefer to monitor 
your playing using a single keyboard amplifier or 
powered speaker, the UNBALANCED [L/MONO] 
OUTPUT jack should be used. 
Output via a mixer
It is commonplace for musical instruments to be 
connected to a mixer in recording and live-performance 
environments. In addition to the unbalanced jacks 
mentioned above, the CP4 STAGE  also features a pair of 
professional-use, balanced XLR jacks that prevent 
unwanted noise from entering output signals. When 
connecting to a mixer, we recommend that these 
BALANCED [L] and [R] OUTPUT jacks be used. (As the 
CP40 STAGE does not feature ba lanced output jacks, its 
UNBALANCED [L/MONO] and [R ] OUTPUT jacks should 
be used in this type of situation.)
 
NOTEThe sound output via the headphones is identical to that 
output via the UNBALANCED [L/MONO] and [R] OUTPUT 
jacks and the BALANCED [L] and [R] OUTPUT jacks. 
Furthermore, plugging in or disconnecting a set of 
headphones has no effect on the sound being output via 
these jacks.

Setting Up
Connecting Pedals
Two different types of pedal can be used with your stage 
piano — foot switches, such as the bundled FC3A and 
the optional FC4A and FC5, and a foot controller like the 
optional FC7. Both are conne cted via the rear panel, 
although the jacks used and  the corresponding functions 
differ as described below. 
Foot switches
The FC3A Foot Switch that comes with your stage piano 
is connected via the [SUSTAIN] FOOT SWITCH jack. It 
functions in the same way as the damper pedal of an 
acoustic piano, allowing notes pl ayed while it is operated 
to sustain for longer than normal after you release the 
corresponding keys.
The FC3A can also function as a half-damper pedal, and 
in such a case, the damper  effect will depend on the 
degree to which the pedal is  operated. You can activate 
the half-damper playing technique as follows:
Press [UTILITY]; select  03: Controller using [V] and [ E] 
and press [ENTER]; set  Sustain to “FC3 Half On” using 
[-1/NO] and [+1/YES]; press  [EXIT] several times to 
return to the Performance screen (page 22). 
An optional FC4A or FC5 Foot Switch can be connected 
via the [ASSIGNABLE] FOOT SWITCH jack so that 
various functions can be assigned to it. This allows you to 
control the assigned parameter by foot.
NOTERefer to the  Reference Manual  (pdf) for details on how to 
assign a parameter to an FC4A or FC5 Foot Switch.
Foot controllers
Used to control an assigned parameter, an FC7 Foot 
Controller (sold separately) is connected via the [1] and 
[2] FOOT CONTROLLER jacks on the CP4 STAGE or via 
the [FOOT CONTROLLER] jack  on the CP40 STAGE. This 
allows you to control assigned parameter(s) such as Part 
volume(s) by foot.
NOTERefer to the  Reference Manual  (pdf) for details on how to 
assign a parameter to an FC7 Foot Controller.
Turning On and Off the 
Stage Piano

Setting Up
Auto Power-Off
The Auto Power-Off function automatically turns off your 
stage piano after a certain period of inactivity, which is 
approximately 30 minutes by default.
If you would like to disable this function, turn off the stage 
piano once and then turn it back on while holding down 
the leftmost key on the keyboard. The message “Auto 
power off disabled” will be displayed on-screen, and this 
function will remain disabled until you set a new Auto 
Power-Off time.
If necessary, use the following procedure to set the time 
until the Auto Power-Off function turns off the stage piano.
Press [UTILITY]; select 01: General using [V] and press 
[ENTER]; select  AutoOff using [E]; set the desired time 
using [-1/NO] and [+1/YES] or the Data Dial; press 
[STORE].
NOTICE
 The stage piano remains charged and draws a small  amount of power even when turned off by the Auto Power-
Off function. To shut it down completely, therefore, unplug 
it from the wall outlet.
 In certain modes of operation such as when data has been  edited, the Auto Power-Off function may not turn off the 
stage piano when the set period of inactivity has elapsed. 
We recommend, therefore, that you always turn off the 
instrument manually when you are finished using it.
 If your stage piano is connected to other equipment such  as amplifiers, speakers, or a computer, but you do not 
intend to use it for some time, we recommend that you 
turn off all devices as described in their owner’s manuals. 
Doing so eliminates the risk of damage to the other 
equipment. If you do not want the stage piano to turn off 
automatically when connected to other equipment, disable 
the Auto Power-Off function.
 Any unsaved data will be lost when the Auto Power-Off  function turns off the stage piano. Be sure, therefore, to 
store your work before it does so.
 If the stage piano’s  AutoOff parameter is set to “off”, that 
setting will be retained when you import system data that 
was saved externally, regardless of the Auto Power-Off 
setting contained in that data. If, however, a specific Auto 
Power-Off time has been set using the  AutoOff parameter 
and system data is imported, the Auto Power-Off setting 
contained in that data will be applied.
 It should be noted that executing the Factory Set function  (page 43) will cause the Auto Power-Off time to revert to 
the default setting of 30 minutes.
NOTE
• Settings for the Auto Power-Off function do not represent exact  times and there may be some variation.
• When the Auto Power-Off function has turned off the instrument,  you will first need to return the [ 1] switch to the Off ( /) position in 
the case of the CP4 STAGE or the Standby ( /) position in the 
case of the CP40 STAGE before turning it back on.
Adjusting Volume and LCD 
Contrast
While playing your stage piano , you can adjust the output 
volume either on the instrument  itself or via your keyboard 
amplifiers or powered speakers. The stage piano’s 
volume is adjusted using the [MASTER VOLUME] dial. 
Set the instrument’s volume to close to 70% of the 
maximum, and then raise the volume on the keyboard 
amplifiers or powered speakers by an appropriate 
amount.
NOTEThe stage piano’s [MASTER VOLUME] dial cannot be used 
to adjust the volume of audio being input via the [AUX IN] 
jack (page 45).
CAUTION
To prevent hearing loss, avoid using headphones at high 
volumes for extended periods of time.
If you find it difficult to read the on-screen text, you can 
adjust the LCD contrast using the [-1/NO] and [+1/YES] 
buttons with the [UTILITY ] button held down.
NOTEThe Contrast  parameter on the General screen from the 
Utility area can also be used to adjust the LCD contrast as 
described above. Refer to the  Reference Manual (pdf) for 
details.
