6. Hints for maximizing the battery running time 1 Fully charge the unit before you use it Toggle the power switch to ON and then OFF again while the instrument is powered by the external power adaptor This will initiate a new charge cycle Charging time of a completely discharged battery can be up to 6 hours IMPORTANT The battery will only be charged when the instrument power switch is in the OFF position Batteries should always be charged at room temperature Charging the instrument at very low or at elevated temperatures may result in early termination of the charging process for example the battery is not fully charged For safety reasons the charging does not start when the internal temperature of the instrument is above 50 C Check the battery indicator in the upper right corner of the display It should indicate full charge when running on battery power after charging 4 segments Power consumption of the instrument is reduced when the RF power is switched off thereby increasing overall battery run time Battery run time is maximal for ambient temperature between 15 and 25 C Self discharge of the battery is much faster at temperatures above 30 C Avoid storing the instrument in very hot places such as behind the windshield of a car parked in the sun Hints for maximizing battery life expectancy 1 2 The battery will reach its best performance after the first few charge discharge cycles Always use the external p
