Altitude Operating Conditions
The characteristics in the table below apply to the module BMX DRA 0804T for use at altitude up to 2000 m (6560 ft). When the module operates above 2000 m (6560 ft), apply additional derating.
For detailed information, refer to chapter Operating and Storage Conditions.
