Clock
Accuracy
*2
*2. The OT’s internal clock has a slight error. At normal operating temperatures and conditions,
with the OT operating from its lithium battery, 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.
