Replace the compartment cover, making sure that it
locks firmly in place.
For battery operation the instrument requires six 1.5V
“D” size, R20P (LR20) or equivalent batteries. (Alkaline
batteries are recommended.) When battery power
becomes too low for proper operation, make sure to
replace all batteries, following the precautions listed
below.
If necessary, also make sure to save all important User
data (see page 56), since custom panel settings are
lost when the batteries are removed.

• If the instrument will not be used for an extended period of time,
remove the batteries to prevent possible fluid leakage.
• Please use the power adaptor when transferring data to flash

drained during a data transfer, both the data being transferred and
the data currently in the transfer destination will be lost.
