⇒ The LEL sensor is factory calibrated to methane. If monitoring a different combustible gas, calibrate the

sensor using the appropriate gas.

⇒ High off-scale % LEL readings may indicate an explosive concentration.

⇒ Protect the LEL sensor from exposure to lead compounds, silicones, and chlorinated hydrocarbons.

Although certain organic vapors (such as, leaded gasoline and halogenated hydrocarbons) may temporarily

inhibit sensor performance, in most cases, the sensor will recover after calibration.

⇒ Any rapid up-scaling reading followed by a declining or erratic reading may indicate a gas concentration

beyond upper scale limit, which may be hazardous.

⇒ Use only Black & Decker VersaPak™ batteries, properly charged and installed in the detector case. (See the

section, "Replacement Parts and Accessories.")

⇒ Only charge batteries using a VersaPak™ charger (such as the D4-VP130 and V-CHARG1). Do not use any

other charger. Failure to observe this precaution could lead to fire or explosion.

⇒ Do not change or charge batteries in a hazardous location. Doing so will impair the Intrinsic Safety of the

unit, and may lead to fire or explosion.

⇒ Read and observe all instructions and precautions in the literature provided with the charger. Failure to do so

may result in fire, electric shock, or other forms of personal injury or property damage.
