Thank You for Purchasing The EM-900 WA from USP!
USP has made every effort to make The EM-900 WA the finest Monitoring System on the market today.
However, for your safety, please take the following precautions when using The EM-900 WA:
For High or Low Risk Patients, the EM-900 WA should be tested regularly to ensure proper notification and awareness
of patients whereabouts in case of actual emergency situation when activated by the WPT-900 transmitter or other
compatible sensors. This is your responsibility as the user of the product.
Certain structures within a household may block the transmitter signal. It is up to the user to test the transmitter within
the area of use to determine if dead areas exist, and where they are located.
Holding the transmitter next to your body or the ground while in use may decrease the range of the transmitter signal. For
High Risk patients, the pendant may be worn on the ankle, which should activate the Wanderer Alert when patient
wanders more than 50 feet from dialer unit.
Using The EM-900 WA does not guarantee that you will contact or receive help. The EM-900 WA is only an aid to assist
you in alerting proper personal of patients moving out of range so the staff can quickly respond to the alarm.
The transmitter should be tested frequently to protect against undetected interference or fault.
For U.S. installations only: The EM-900 WA is required to comply with Part 15 of the FCC Rules and regulations. As
such, it has limited transmitter power and therefore limited range.
The monitoring system cannot respond to more than one transmitted signal at a time and may be blocked by radio signals
that occur on or near their operating frequencies, regardless of code setting.
