6. Maintenance
The Ranger Pro device needs minimal maintenance. If a device fails, it may be due to a weak
battery, environmental damage, or even a blocked wireless connection.
6.1 Monitor Battery Levels
To monitor your Ranger Pro device’s battery status, use your network infrastructure software or
the NFC reader and the Ranger Pro software. Depending on the device operating mode and
configuration, the battery lasts up to five years.
Check the devices' battery status monthly. If a battery status is medium, be sure you have
replacement batteries in stock or on order. However, for optimal device life, we recommend that
you don't store batteries for more than 12 months. Under optimal conditions, we recommend
replacing the battery within 3 to 6 months once it reaches the Low state.
Install only approved D-sized 3.6V lithium-thionyl chloride batteries. For details and ordering
information, see the Ranger Pro Datasheet (document 125M5237) available from Bently.com.
