Having a strange issue with my TRX-1. Had to replace the SD card in the scanner - new one in and operating fine. However fresh fully charged batteries show not charged on the screen and get the alarm when not connected to an outside source. The battery symbol on the screen shows an "empty" battery and shows the "charging" animation when plugged in. They do run for a while when disconected from the outside power source - not sure how long. Any thoughts on what is happening. It is running just fine when plugged in!!! Whistler support wants me to send back to them but thought I would ask here first. Thanx!!!
