v
In order to maintain the “water and dust resistant performance” of the
unit, observe the following precautions.
- Make sure that the battery compartment lid, the side cover and the
top cover of the unit are fi rmly closed.
- Do not open the battery compartment lid while the unit is wet.
- Do not leave the unit in a wet state. Always wipe off any moisture
and properly dry the unit.
- Have the unit regularly checked and calibrated, to ensure continued
“water and dust resistant performance”.
- We recommend to have the packing inside the case, the side cover and
the top cover replaced regularly (fare-paying service). The recommended
replacement cycle is two years. If more than two years have elapsed,
the “water and dust resistant performance” of the unit will no longer
be guaranteed. Regarding replacement of the packing, the side cover
and the top cover, please contact your supplier.
The life of the backup battery for the internal clock of the unit is limited.
You should have the battery replaced about once every two years. Regarding
replacement of the battery, please contact your supplier.
Please note that this product is warranted up to the product purchase price
against defects in material.
Never format optional program cards such as the VX-55EX and VX-55WR
with SD memory card formatting software (such as SD Formatter, etc.).
Otherwise the program data on the card will be erased and the respective
functions can no longer be used. Restoration of the erased program is not
warranted.
Dispose of the unit and of batteries only according to national and local
regulations at the place of use.
