Display backlights
The display backlights have a limited useful life. Their life time depends upon the conditions under
which they are operated, e.g. on/off cycle times, operating temperature, symmetry of the lamp
supply voltage. The times indicated below are typical values taken from the manufacturer’s data
sheets. We recommend that the backlights are replaced after this time has elapsed.
When it becomes necessary to exchange the backlights, please contact your Hauser
Service department for more information.
