1.3 SENSOR OVERVIEW

The sensor is the piece that comes in a sterile, sealed sensor pouch. The sensor is made up of an
applicator, a sensor pod, and a sensor wire. You remove the applicator after insertion. The sensor pod stays
on your belly for the entire sensor session, up to 7 days. The pod is made of plastic and an adhesive patch.
The sensor wire is thin and flexible, and inserts just under the skin of your belly. It is attached to the sensor
pod, and is made of silver and platinum metal with polymer membranes. You discard the sensor at the end
of the session.
See Chapter 14 for Product Specifications.

1.4 TRANSMITTER OVERVIEW

The transmitter is the gray, plastic "chip" that snaps into your sensor pod. The 9438-01 transmitter (including
sensor pod) is 1.5 inches long, 0.9 inches wide and 0.5 inches thick. The 9438-05 transmitter (including
sensor pod) is 1.5 inches long, 0.9 inches wide and 0.4 inches thick. Once snapped into the sensor pod, the
transmitter wirelessly sends your glucose information to the receiver. The transmitter and sensor are water
resistant when properly connected. Do not throw away your transmitter. It is reusable.
The transmission range from the transmitter to the receiver is up to 20 feet without obstruction. Wireless
communication does not work well through water, so the range is much less if you are in a pool, bathtub or
water bed.
The transmitter battery will last at least 6 months. Once you see the transmitter low battery screen, replace
the transmitter as soon as possible. Your transmitter battery may drain as quickly as one week after this
alert appears.
