Bobs description is accurate. As an example we had a power hit last night. My gps rcvr came up at some odd time. (normally its all fine in 10-30 seconds) I guessed the battery was bad its been 5 years. Sure enough sometime later in hours the time is correct. Time to get a screw driver and battery. :-) Regards Paul WB8TSL
