Charging the transmitter
Before using the transmitter for the first time, you must fully charge the transmitter battery, which may
take up to eight hours. It is recommended to recharge the transmitter after each sensor use. A fully
charged transmitter battery will work more than 14 days without recharging. After 14 days of use, the
transmitter will fully recharge in less than two hours.

will not charge with its green light on. Wait for the green light to turn off, then connect the
transmitter to the charger.
2 Connect the transmitter to the charger by lining it up, flat side down, with the
charger. Push the two components together fully.
3 Within 10 seconds after the transmitter is connected, a green light on the charger will flash for one to
two seconds as the charger powers on. For the rest of the charging time, the charger's green light will
flash in a continuing pattern of four flashes, pause, four flashes, pause.
