1Only applicable if the optional internal span gas generator is installed.

2Only applicable if the 9110T is equipped with an oxygenator option.

3It is possible to assign more than one flag to the same Hessen status bit. This allows the grouping of similar flags, such as all temperature warnings, under the same status bit.

Be careful not to assign conflicting flags to the same bit as each status bit will be triggered if any of the assigned flags is active.
