Do not remove the memory card or perform any 
other operation (such as turning off the camcorder) 
during deletion. Also, be sure to use the provided 
AC Adapter, as the memory card may be corrupted 
if the battery becomes exhausted during deletion. If 
the memory card becomes corrupted, initialize it.

● Be sure to always use the same tape and memory 

card together as they were during recording; 
otherwise, the camcorder cannot recognize Tape 
and Memory Card IDs to perform Navigation 
Function properly.

● Check if an appropriate tape and memory card 

are loaded when the following messages appear: 
“UNABLE TO USE NAVIGATION”, “THIS 
MEMORY CARD IS NOT COMPATIBLE”.

● If you change the memory card while shooting on 

one tape, two memory cards will share the tape’s 
thumbnail images. We recommend that you use 
one memory card for one tape.

● Navigation Search does not work if the current 

position is at a blank portion on the tape. Also, do 
not leave a blank portion partway through the tape 
when shooting; otherwise, Navigation Function 
does not work properly.

● Before shooting newly over a recorded tape, be 

sure to delete all thumbnail images of the previous 
recording from the relevant memory card.

● If you copy thumbnail images from one memory 

card to another via a PC, Navigation Search does 
not work with the copied memory card.
