CAUTIONS WHEN INSERTING  
SD CARDS
•  You  can  use  16MB  to  32GB  SD  cards. 
For  a  list  of  operation-certied  SD  cards 
please  refer  to  the  ZOOM  website:

•  If  you  use  an  SD  card  that  was  used 
by  a  computer,  digital  camera  or  other 
machine,  formatting  in  the  H4n  Pro  is 
required.
•  If  “No  Card”  appears  on  the  display  at 
startup, check  if the  SD card  is correctly 
inserted.
•  When  “Format  Card”  appears  on  the 
display at startup, this means the SD card 
has not been formatted in the H4n Pro. To 
format it, press the DIAL and select YES.
•  When  the  startup  screen  says  “Card 
Protect”,  the  card  is  write-protected.  To 
disable  this,  slide  the  lock  switch  on  the 
SD card.
No  SD  card  warning  when 
starting up.
This warning will appear if an 
SD card is not in a recognized 
format. Select YES to format 
the card. This will delete all of 
its data.
