    For best results, replace or recharge the batteries when you first see this warning. Low Battery Shut Down To prevent erratic operation at very low power levels, the TSG 601 will shut it- self down if the battery voltage drops below a second, lower threshold that also depends on the Battery Type setting.

  • Page 80: Preventive Maintenance

    Dirt can provide high-resistance electrical leakage paths between con- ductors or components in a humid environment. CAUTION. The TSG 601 case is made of molded plastic. Do not allow water to get inside of any enclosed assembly or component. Do not clean any plastic materials with organic cleaning solvents, such as benzene, toluene, xylene, acetone, or similar compounds, because they may damage the plastic.
