5. Frequent full discharges add strain to the battery pack Several partial discharges regular use with frequent recharges are better for lithium ion batteries than one total discharge e Use the right charger Each type of battery has its own technology its own rate of charge and so on The AC power supply adapter and the 12VDC auto adapter supplied with the unit are designed specifically for the Gx Data logger lithium ion batteries Use of other adapters will void the warranty e Keep the lithium ion batteries as cool as possible Avoid heat Short battery life is more likely to be caused by heat rather than charge discharge patterns Avoid exposure to direct sunlight or a hot car for example If the batteries will not be used for a month or longer they should be removed from the Gx Data logger and store it in a cool clean place see Section II 3 e Expect to replace batteries periodically The life span of batteries is highly dependent upon many factors including charge discharge cycles storage times and operating and storage temperatures e Dispose of batteries in accordance with local municipality guidelines DO NOT e Never short circuit the battery pack Short circuiting a Li ion battery can cause it to ignite or explode and as such any attempt to open or modify a Li ion battery s casing or circuitry is dangerous e Do not expose the Li ion battery pack to high temperature environments This can cause the battery to rupture

15. B for NMEA data output The specific port that you ll configure to output NMEA data Port A or Port B will depend on which of the Pathfinder receiver units you are configuring for application with the Gx and whether or not you would like to have the Gx unit signal the receiver to perform GPS tracking only when a survey application requires GPS data as opposed to the receiver continuously tracking the GPS signals even when not required to do so by the Gx For both the XR and XRS receivers you can select to configure either Port A or Port B for NMEA data output The important issue with regard to the XR and XRS receivers is the connection cable itself If you would like the Gx unit to signal the GPS receiver when GPS tracking is required by the Gx during particular survey applications you would select cable number 30231 00 to connect the receiver to the Gx 67 This is a power saving mode of operation for the GPS receiver since when GPS tracking is not required by the Gx the GPS receiver will be in sleep mode which is a low battery power consumption mode Conversely if you d like the GPS receiver to be continuously tracking the GPS signals at all times you would select cable number 30945 With this cable the Gx does not control when the receiver is in GPS tracking mode but rather the receiver will begin tracking as soon as battery power is applied and will continue to track until the battery power is switched off This wou
