pushing the assembly into place.

all assemblies are correctly installed.

Changing the Battery
To ensure better performance and maximize battery
life, a new battery block for Pipetman Ultra has been
designed. The battery pack includes two silve-oxyde
plated 1.55V generic code 391 (size 11.6 x 2.1 mm).
Although changing the battery block does not aff ect the
calibration, you may wish to take this opportunity to carry
out performance check of the pipette (see chapter 15)
.
If you need to change the battery block, proceed
as follows:
1) Ensure the pipette is in the locked position,
remove the tip-ejector,
2) Remove the battery
compar tment cover
(the calibration key is
equipped with a tool
for opening the battery
compartment cover)
by
carrying out the follow-
ing steps, with reference
