Group 1
The SMN-823W uses RF energy only for its internal
function. Therefore, its RF emissions are very low and are
not likely to cause any interference in nearby electronic
equipment.

1. Introduction
The SMN-823W is a battery operated motion sensing tag. The SMN-823W transmits LF signal upon
detection of motion to trigger close proximity communication to other tags. SMN-823W is designed to be
installed onto automatic soap dispensers to allow Hand Hygiene Compliance in hospitals and clinics.
When the SMN-823W detects motion, it will transmit a unique ID using low frequency. SMN-823W also
has wifi to allow transmittion of data to a server for monitoring of status, battery level, etc.
The button on the SMN-823W allows for maintenanpg 5ce by the user.

4. First install on soap dispenser
1. Ensure the tag is in SLEEP mode (no LED blinking). If not, long press (5sec) the User button. 3
beeps are heard, Red LED blinks once.
2. Install the bracket onto the soap dispenser using double-sided tape.

3. Install the tag onto the bracket.
4. Long press (5sec) the User button to WAKE the tag. 3 beeps are heard, Green LED blinks once,
then starts blinking periodically.
Result:
1. Usage level of the soap (Activation Count) will be reset to 0.

10
5. To change new battery
1. Remove the tag from the dispenser (2 screws).
2. Unscrew the tag (6 screws) and remove the back cover.
3. Disconnect the existing battery.
4. Connect the new battery. Press the Reset button once (5 beeps are heard).

11
5. The tag will automatically default to WAKE mode. Confirm the tag is in WAKE mode by observing
the blinking Green LED.
6. Replace the back cover and screw.
7. Install the tag back into the bracket.

12
Result:
1. Usage level of the soap (Activation Count) will be maintained.
2. Transmit Count (wifi), and Battery Level will be reset.
6. To change new soap liquid
1. Put the tag to SLEEP mode (long press the User button until 3 beeps are heard, red LED blinks
once).
2. Long press the User button to WAKE the tag (3 beeps are heard and Green LED starts blinking).

13
Result:
1. Usage level of the soap (Activation Count) will be reset to 0.
7. To remove tag for cleaning (no change of liquid soap)
1. Remove the tag from the dispenser for cleaning.
2. Install the tag back into the bracket.

14
Result:
1. All parameters will remain as no buttons are pressed.
8. Using the tag
The tag requires both vibration and proximity sensing to successfully activate. When mounted on the
soap dispenser, when the staff puts his hand under the dispenser, the motor from the dispenser will
activate the motion sensor, at the same time, the presence of the staff’s hand will activate the proximity
sensor. Once these 2 conditions are fulfilled, the SMN-823W will send a signal to trigger the staff tag of a
successful hand wash event.

9. Low battery behavior

16
The tag continuously monitors the battery level. The battery capacity percentage is reported via wifi,
and the low battery status can be viewed on the LED window. The LED will blink periodically in red
instead of green. The tag will also report low battery status if it was internally restarted due to low
battery. The tag will continue to transmit wifi its status until the battery dies completely.

EMC compliance summary: When the Air +/- 15kV is applied, the EUT emits a "beep" four sounds, a red
light flashes, and a red light flashes for one second.
SMN-823W is not a life support system and does not cause any harm to the patient or environment. A
reset due to ESD will not affect essential performance and without basic safety consideration.
