1.4 TRANSMITTER OVERVIEW

The transmitter is the gray, plastic "chip" that snaps into the 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 the glucose information to the
receiver. The transmitter and sensor are water resistant when properly
connected. Do not throw away the transmitter. It is reusable. When
healthcare professionals use one transmitter for multiple patients, the
transmitter must be cleaned and disinfected between each patient's use.
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. The transmitter battery may drain as quickly as one week after
this alert appears.
