1 Purpose
The purpose of this document is to provide user instructions for the SDM3 Speed and
Distance Monitor.
2 Overview
The SDM3 represents a next-generation technology platform of small, low-power speed and
distance sensors. The sensor is designed to be worn clipped to the shoe laces. Real-time
running/walking information including distance, instantaneous speed, and cadence is sent
from the foot sensor to the wrist unit for real-time display. Powered by a coin cell battery, the
sensor communicates to the wrist unit via RF data transfer operating in the 2.4 GHz ISM
band and using Dynastream’s ANT+SPORT network. The SDM3 is designed to work with
Dynastream’s SMWx Sport Monitoring Watch family and is capable of working with any
ANT+SPORT based watch that is enabled for ‘SDM’ sensor device types.
3 User Instructions
3.1 Shoe Attachment
The SDM3 footpod must be attached securely to the laces of the running shoe using the
supplied clip, as shown below. The pod must remain firmly in place for optimum accuracy.
Tight lacing will reduce jiggling or bouncing of the pod, which can be detrimental to speed
and distance accuracy. To remove the pod from the shoe, press down firmly on the front
tips of the clip to disengage the clip from the recessions in the pod and remove pod from
clip.
1) Slip the pod clip under the laces of an untied shoe.
2) Tie shoe to secure clip in place.
3) Insert back of pod into the clip matching the recessions in the edge of the footpod with
the protrusions in the clip.
4) Press firmly on the front of the footpod until it “clicks” into place securing it firmly to the
laces.
3.2 Turning the Footpod On and Off
The SDM3 foot pod will turn itself on automatically once adequate motion is sensed
(equivalent of 3 - 4 strides), as indicated by three blinks of the red LED. If the LED remains
solid upon power up this is indicative that the pod is not transmitting data and may require
service. After running, the pod will automatically turn off after 30 minutes of inactivity,
indicated by two (2) blinks of the red LED.
