【Introduction】

Congratulations! on the purchase of your new MSR Wireless Temperature
Monitor. You may now “Rest Assured” of your loved one’s temperature
either up close or from a distance, even from another room! “Why Wake
your Sleeping Angel up”?
Your new “Wireless Temperature Monitor” is a Technologically advanced
medical device intended for remote monitoring of body temperature for
up to 100 hours of continuous use. It is intended for patients 3 years old to
adult. The device consists of two parts: the transmitter and the receiver.
The transmitter monitors body temperature (via the underarm sensor) then
automatically transmits the measured temperature reading to the remote
receiver.

The following are key features:

• Clinically Accurate: Meets or exceeds ASTM and CE accuracy
standards.

• Accuracy Assurance Function – temperature reading transmits every
15 seconds!

• Fever alarm and fever receding points setting --- Hi, Lo.

• Memory Function - tracks previous readings every 30 minutes.

• Alarm Function – Alarm sounds when temperature deviates from
personalized pre-set parameters.

• Additional Alarm Function – Alarm sounds should sensor become
disconnected.

• Clock Function.

• Room Temperature Function – Scans and reads ambient temperature.

• Backlit for easy night reading when any button on the control panel
is touched.

• FCC approved transmission frequency – 433.92MHz.

• Measures in Centigrade and Fahrenheit.

【Responding to Temperature Alarm】

After the receiver sounds the alarm, it will continue to ring unless the
receiver is switched off manually (alarm can be temporarily turned off by
pressing any key on the receiver )

Caution: It is dangerous to automatically switch off the receiver alarm

without nding out why it sounded in the rst place. Doing so makes the

caretaker forget the importance of taking immediate action for the patient.
The correct procedure is:

1. Hear the receiver alarm sounds.

2. Turn off the “alarm” by pressing any button on the receiver.

3. Go to the patient immediately.

4. Provide proper care to the patient.

5. Reset or turn off the receiver if necessary.

house.
Do not expose it to sunlight or place next to high temperature stove. Heat
can negatively impact functioning of the batteries and electric circuit.

Removing batteries:

If the receiver is not in use, the batteries should be removed in order to
conserve battery life.
