Battery Operation and Maintenance
The Radius-7 includes a Battery Module containing a lithium ion rechargeable battery.
Before using the Radius-7, the Battery Module should be fully charged. See Charging the
Radius-7 Battery Module on page 36 of the Operator's Manual.
The Battery Module requires approximately 6 hours for charging.
Memory effects of the battery may shorten run-time. When Battery Module run time is
significantly reduced, it is advisable to completely discharge and fully recharge the Battery
Module.
Note: Always store the Battery Module on the Root. Do not place it on a conductive surface
where the connection pins may be shorted.
The following tables outline the estimated run times of Radius-7. The time estimates are
based on Radius-7 with fully charged Battery Module.

Under normal operation, no internal adjustment or recalibration is required. Safety tests and
internal adjustments should be done by qualified personnel only. Safety checks should be
performed by trained personnel at regular intervals or in accordance with local and
governmental regulations.
Before conducting Safety Checks examine the device. Look for cracks or possible openings in
the enclosure. If the device appears or is suspected to be damaged, return for Servicing.
To conduct Safety Checks follow the procedure outlined in this chapter. If Radius-7 fails any of
the described tests, discontinue its use and refer to the Troubleshooting section.
Before performing the following tests, do the following:
• Disconnect any sensors or patient cables.
• Disconnect the Battery Module from the Instrument Module. See Chapter 3- Setup
