will need to be recalibrated.
Repeat this same sequence with the left earphone.

3.4 PAPER SUPPLY
To streamline each testing session, check the amount of paper left
inside the printer compartment, and keep extra rolls of paper so that
the paper can be easily changed without upsetting your schedule.
NOTE
The number of tests per roll of paper will vary with the type of tests being
performed. See pages 58 and 60 for approximations and paper ordering
information.
