Accuracy
*2
*2. At normal operating temperatures and conditions, with the OT operating from its lithium bat-
tery, the degree of error is 65 seconds per month. Variations in operating conditions and battery
life can cause this error to vary from -380 to +90 seconds per month. For systems where this
degree of error will be a problem, the user should be sure to monitor this error and make
adjustments when required.
±65 seconds/ month (at room temperature)
• When the message “RAAA051 Low battery” is displayed, supply power to the display
unit and fully charge the battery. The battery charges within 24 hours to a level which
allows backup operation. Completing a full charge requires about 96 hours (4 days).
• A Lithium battery’s lifetime is: 10 years when the battery’s ambient temperature is 40°C
[104°F] or less. 4.1 years when the battery’s ambient temperature is 50°C[122°F] or less.
1.5 years when the battery’s ambient temperature is 60°C[140°F] or less.
When used for backup:
Approximately 100 days, with a fully charged battery.
Approximately 6 days, with a half-charged battery.
