NOTES:
œThis table shows the maintenance for up to 8000 hours. After this, repeat from the start or the table.
œFor places with symbols such as E (k) and F (k), carry out checking and cleaning, and replace if necessary.
œThis periodic maintenance check table changes considerably according to the using conditions and environment.
œRefer to the (POWER FAILURE/DEW/USED TIME) menu for the length of time the unit has been used.
œAs the life of parts may be shortened if foreign particles and dusts remain accumulated on the tape guides and rotating and contacting portions, clean if dirty.
œDusts and other foreign particles on the tape guides may also shorten the tape life and lower picture quality, therefore clean thoroughly.
