Why after 6 seconds power up (beep) does itself off?
The screen comes on after beep then it fades out and turns off after 6-7 seconds. I tried numerous new batteries and cleaned all internal electronics.
The Garmin eTrex Vista-H has a 2.0" x 4.4" x 1.2" body, and a black and white screen with 160 x 288 pixels display resolution screen. It weighs 5.3 oz or 150 g, and requires 2 AA batteries which last up to 18 hours. The device is water proof but does not float.
