Note: If you do not intend to use the scanner for extended periods of time (more than a month), we recommend that you remove the batteries from the scanner. rechargeable batteries Nickel Metal Hydride (NiMH) batteries can be recharged by using a battery charger (batteries and charger are not included). Some things to keep in mind when using NiMH batteries are: • Always recharge all four NiMH batteries at the same time. One lowcharged battery will reduce the battery life for all four batteries in the scanner. • For NiMH batteries to reach optimal capacity and performance, they should first be discharged completely and recharged four separate times. • After long-term storage of NiMH batteries, recharge them before using them again. Battery cells generally discharge at about 1 percent per day at room temperature. power conservation To conserve battery power, the scanner turns off automatically if there is no button activity for three minutes (unless it is connected to a computer). 37
