This chapter contains information about cleaning, battery operation, performance

Cleaning
Root is a non-sterile and reusable device. The surface of the Root should be cleaned when the
device is visibly dirty, before and after each procedure, and/or according to hospital practice.
To surface clean, wipe down the outer surface of Root using any of the following:
• Cidex Plus (3.4% glutaraldehyde)
• 10% bleach solution
• 70% isopropyl alcohol solution
Do not allow liquids to enter the interior of Root. Using the recommended cleaning solutions
on the touchscreen will not affect the performance of Root.
Replacing the Fuses
If a power-related problem causes one or both of the fuses to fail, the fuse(s) will need to be
replaced. Replace fuse(s) with UL Listed fuses rated 250V, 2 amp, metric 5x20 mm and with a
time delay breaking capacity of minimum 1500A.
WARNING: To ensure safety, only replace with appropriately rated fuses.
The fuses can be removed by hand or with a 5-millimeter or 3/16-inch screwdriver.
To replace the fuse(s)
1. Power Off Root completely. Do not put in Sleep Mode. See Sleep and Power Off on
page 88.
2. Remove the AC power cord from the Power Entry Module in the back panel.
3. Remove the fuse holder by pulling it forward from the Power Entry Module.
4. Remove a fuse by gently pulling the top of the fuse away from the center and then
pulling up. The fuse should easily be removed. Do not force.
5. Place a new fuse in the fuse holder.
6. If replacing both fuses, repeat steps 4 and 5 for the second fuse.
7. Slide the fuse holder back into the Power Entry Module and press firmly to make
sure it is secure.
Root is ready to be reconnected to AC power. If the fuses fail shortly after replacement, Root
requires service. See Repair Policy on page 160.
