POWER SOURCES Power from internal batteries Internal power is obtained from 4x 1.5 V Alkaline batteries or four 1.2V, rechargeable batteries, Model R14, Baby or C size. Note: Not applicable for Model TRX-II IS. Installation of the batteries Switch the calibrator off before installing new batteries. Note: Not applicable for Model TRX-II IS. - Page 17 lowered. If the batteries do not reach their normal capacity after a 14 hour charging period, cycle complete discharging and charging at least twice. If the batteries remain weak they should be replaced. No particular brand of Ni-Cd is recommended although cells rated at 2.0 Ah have preference over the more generally available 1.8 Ah cells.
