Storage recommendations
Storage conditions
D20MX INSTRUCTION MANUAL
Always store the D20MX in an environment compatible with operating conditions.
Recommended environmental conditions for storage are:
•
Temperature: -40 °C to +85 °C
•
Relative humidity: 5% to 95%, non-condensing
•
Maximum altitude: 12192 m [40,000 feet] above sea level
Do not store the D20MX above 60°C for extended periods of time as this shortens the life of
the super capacitor and reduces the backup time of the real time clock.
When powered off, the D20MX real time clock remains active for 14 days at -40°C to 60°C,
and greater than one month at 25°C. Information in the NVRAM remains stored indefinitely
since flash memory is used.
