Charging the transmitter
Before using the transmitter for the first time, you must fully charge the transmitter battery. This may take
up to 8 hours. It is recommended to recharge the transmitter after each sensor use. A fully charged
transmitter battery works more than 14 days without recharging. After 14 days of use, the transmitter
recharges in less than 2 hours.
To charge the transmitter:
1 If a green light on the transmitter is lit or flashing, do not connect it to the charger.
The transmitter will not charge with its green light on. Wait until the green light
turns off (approximately 30 seconds), and 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
1-2 seconds as the charger powers on. For the rest of the charging time, the charger’s green light will
continue to flash in a pattern of four flashes with a pause between the four flashes.
4 When charging is complete, the green light on the charger will stay on, without
flashing, for 15-20 seconds and then turn off.
5 After the green charger light turns off, disconnect the transmitter from the charger. The green light on
the transmitter will flash for about 5 seconds and then turn off.
