selects the next mode and DOWN selects the previous. The mode is displayed breefly when changed, and the pulse
and response counters are reset. The test can be terminated manually with the interrupter.
The memory:
Test results are stored in every audiogram, and for every frequency as a percent figure. There is memory for the left
and the right earphone. It is possible to run a SISI test using the bone conductor and the mono insert phone too, but
the results are not stored separately, they use the same memory as left and right. When SISI is selected on the channel
2 function selector, the VU display recalls the stored test results when the frequency and channel is changed. These
results may be erased by pressing CLEAR (with shift). This only clears the single result that corresponds to the currently
selected frequency and channel. When a printout is done, all the SISI test results are shown in a table below the
audiogram.
ABLB: (Alternate Bilateral Loudness Balance)
ABLB involves both channels by activating the two interrupters twice on each channel, in the following way:

channel 2 FUNCTION choose ABLB.
To start the test: press the channel 2 interrupter.
