    WHY A RELIABLE BATTERY IS CRITICAL

    Uninterrupted Field Work: Complete site surveys and troubleshooting without being tethered to a vehicle or outlet.

    Preserves Calibration & Settings: A sudden power loss from a failing battery can interrupt measurements and, in rare cases, risk internal settings.

    Cost-Effective Maintenance: A simple battery swap is the most economical way to restore the full portability and utility of your valuable analyzer.

    SAFETY & OPERATIONAL WARNINGS

    For Professional Use: Intended for use by qualified RF technicians, engineers, and field service personnel.

    Use Approved Charger Only: Must be charged using the official Agilent/Keysight FieldFox charger or docking station. The analyzer itself often acts as the smart charger. Using a third-party charger can damage the battery and analyzer.

    Follow Manufacturer Guidelines: Refer to the "Powering the FieldFox" section of your Agilent/Keysight FieldFox User's Guide for proper battery handling, storage temperatures, and charging instructions.

    Calibration Consideration: While a battery change doesn't typically affect calibration, ensure your analyzer's calibration is current for accurate measurements.

    Proper Disposal: Recycle at a certified e-waste facility for lithium-based batteries.
