TERMINAL SETUP
Install/Replace SIM Card (GSM/GPRS Models)
NOTE The Vx6xx terminal automatically shuts off when the smart battery reaches the critically low charge state. If this occurs, the smart battery must be recharged for a minimum of 1/2 hour before it can power the terminal. It may take several recharge attempts to reset the safety circuit when charging a smart battery that has been discharged below this critical state.
Battery Life The Vx6xx smart battery can be charged and discharged hundreds of times, but will eventually wear out. When operating times are noticeably shorter than usual, it is time to buy a new battery (see Accessories and Documentation for ordering information).
WARNING Do not dispose of batteries in a fire.
