OPTIONAL RECHARGEABLE BATTERY PACK
A. INSTALLATION
For complete portability, the HemataStat II will operate on a rechargeable
battery pack, which can be ordered as an option. The battery pack will need to
be installed in the device as described below and fully charged before normal
operation.
1. Make certain the lid is closed and locked and the centrifuge is unplugged
from the electrical outlet. Lock the lid by firmly pressing down on the lid
tab.
2. Place the device upside down on a smooth, flat surface and on a cloth or
other protective material to prevent scratching the lid.
3. Locate the battery pack cover. Using a small head Phillips screwdriver,
remove the screws holding the battery pack cover in place. Retain the
screws. Remove the battery pack cover.
4.
Connect the battery pack plug into the connector located inside the battery
pack cavity. Put the connector inside the hole of the housing with the
connector release tab facing up. Position the battery pack inside the
compartment. Lay the cable along side the battery pack to avoid crimping.
5. Replace the battery pack cover and secure with the screws provided.
6. Plug in the HemataStat II and fully charge the battery pack.
B. CHARGING THE BATTERY PACK
The battery pack is always charging whenever the HemataStat II is plugged into
an electrical outlet. Since the battery pack cannot be overcharged, the device
may remain plugged in continuously without harm. Charge the battery pack
overnight (or an equivalent period of time). The percentage of remaining
battery pack capacity may be determined at any time by performing the
following procedure.
