Low notes sound wrong, or are buzzy
If you set the volume to the maximum setting, the sound may be distorted depending on how you perform.
If this occurs, turn down the volume.
If you don’t hear this in headphones:
Performing at high volumes may cause the speakers or objects near the unit to resonate. Fluorescent lights or glass doors may also
resonate sympathetically. In particular, this is more likely to occur for lower notes and higher volumes. You can take the following
measures to minimize resonances.
• Locate the speakers 10–15 cm (4–6 inch) away from walls or other surfaces.
• Keep the volume down.
• Move away from the objects that are resonating.

changes when you record a
performance as audio
Thanks to its multiple number of speakers, each of which can be used to play a different portion of the overall sound, the unit is capable
of producing piano sounds that possess great depth and seem to have three-dimensional presence.
Such effects are produced when you play something on the keyboard, or when you play back a song that’s been recorded as an SMF.
However, when you make an audio recording, the song will consist of two channels (stereo), and such effects cannot be reproduced.

Problems when connecting to a wireless LAN
Cannot connect to wireless LAN
• Check that your wireless LAN access point supports the WPS standard.
If your wireless LAN access point does not support WPS, connect using the procedure described in “Connecting to a Wireless LAN
Access Point That You Select (Select AP)” (p. 60).
• The HPi-50e does not support the 802.11a and 802.11b wireless standards. Please use 802.11g or 802.11n (both at 2.4 GHz).
• WEP authentication is not supported. Please use WPA or WPA2 authentication.
• Be sure that your wireless LAN access point is set to use DHCP.
• If the HPi-50e cannot connect to a wireless LAN access point that it previously could connect to, make sure the “Connecting in Ad-Hoc
mode” (p. 61) setting is set to “OFF.”
• You may not be able to connect to the wireless network depending on the condition of the wireless signal. In this case, refer to the
procedure described in “About the Wireless LAN Function” (p. 59) and try selecting and connecting to the wireless LAN access point
again.
• The HPi-50e remembers a limited amount of information about network connections. Once the limit is reached, data from new
connections may overwrite older data.
All connection data will be erased if you perform a factory reset.
If network connection information is erased, repeat the connection procedure and connect again.
“Error : 46” appears on the display and
the HPi-50e cannot connect to the
wireless LAN access point
The access point is not supported. Please use WPA or WPA2 authentication.
Connection is unstable
Wireless communications may be unstable if the condition of the wireless signal is poor.
If the wireless communications are unstable, responsiveness may deteriorate and audio drop-outs may occur.
The following may solve the trouble.
• Move the HPi-50e and the wireless LAN access point closer to each other.
• Change the channel setting on the wireless LAN access point.
