If there are problems during operation of the H4n, check the following points first.
Problems during recording/playback
◆ No sound, or sound is very weak
• Check the connections to your monitor system, and the volume setting of the system.
• Check whether the volume level setting of tracks 1 − 4 is appropriate.
◆ Recorder stops during playback
• When playback is carried out with a track in recording standby condition,
a temporary file is created in the H4n. If the remaining capacity of the SD card is
low, the temporary file may use up all the remaining space, causing playback to
stop. In such a case, cancel the recording standby condition of the track.
◆ No sound from connected instrument,or sound is very weak
• Check input source settings (➝P.047).
• Check setting of INPUT [1], INPUT [2], and [MIC] buttons. (➝P.047).
• Check whether recording level setting is appropriate. (➝P.047).
• If INPUT [1]/INPUT [2] jacks are used, try raising output level of connected
instrument.
• When the monitor function (➝P.071) is off, the input signal can only be
monitored if a track is set to recording standby or if the recorder is in the
recording standby condition.
◆ Cannot record on a track
• Verify that [REC] button and button for recording target track are lit in red.
• If a project is protected, recording is not possible. Use another project or turn
protection off (➝P.125).
• Verify that an SD card is inserted in the slot.
• Check whether the hold function is enabled (➝P.020).
• If the indication "Card Protected" is shown on the display, the SD card is write-
protected. Slide the write-protect switch to the non-protected position.
◆ Cannot perform bounce
• Verify that the level of tracks 1 − 4 is not fully lowered.
• Verify that there is sufficient free space on the SD card.
Other problems

• Check whether effect section is on. The effect section is off by default in stereo
mode and in 4-track mode.
◆ Cannot use tuner
• Check whether the jack to which the instrument is connected is selected as
input source.
◆ Unit is not recognized when connected to a computer via USB
• Check whether the operating system of the computer meets the
requirements listed on page 035.
