1.4 TRANSMITTER OVERVIEW
The transmitter is the gray, plastic “chip” that snaps into your sensor
pod. The transmitter (including sensor pod) is about 1.5 inches long, 0.9
inches wide and 0.5 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.
