The internal memory battery should typically last three to five years. If
the GPS 75 detects a low memory battery, you will be informed with the
message “Memory Battery Low”. You should return your unit to an
authorized GARMIN service center as soon as possible for service.
Failure to do so may result in loss of data each time you turn your unit
off (indicated by the message “Stored Data Lost”).
Your GPS 75 contains a highly accurate crystal oscillator which should
provide many years of reliable operation. If the unit detects excessive
oscillator drift, you will be informed with the message “Osc Needs
Adjustment”. You should return your unit to an authorized GARMIN
service center as soon as possible. Failure to do so may result in degraded
acquisition performance.
