Charging the Monitor
The lithium-ion battery inside the monitor, when fully charged,
is capable of running for 28 hours. For example, if you drive 4
hours per day, the monitor can be used for one week without
connecting the power cord. When the low battery icon
appears, a recharge is required.
You need to charge the battery immediately. It will take 2.5
hours to charge fully.
Replacing the Transmitter Battery
When the sensor low battery icon shows on the monitor and
corresponding tire icon is flashing, the sensor battery needs
replacement. A CR1632 battery cell is recommended which
operates at -4F to 176F (-20C to +80C). You can buy
replacement batteries from most retailers.
Follow these steps to replace the battery:
1. Remove the sensor from the valve stem.
2. Unscrew the sensor cap.
3. Take the battery out.
