6. Maintenance
Ranger Pro Gateways need minimal maintenance. If a device fails, it may be due to
environmental damage, or even a blocked wireless connection.
6.1 System Time Backup Power Battery
Ranger Pro Gateways use a Lithium coin-sized batter to keep the real-time clock and radio
oscillator running when the gateway does not have power from the PoE or external power
connector.
The battery should be replaced if the Ranger Pro Gateway time keeps resetting to the same
incorrect date and time after power loss.
Install only approved CR2032 Lithium batteries. For details and ordering information,
see the Ranger Pro Gateway datasheet (document 157M8584).
6.2 Clean and Inspect Devices
Use a damp cloth to clean the exterior of the Ranger Pro Gateway in potentially hazardous
environments.
