LOW BATTERY
It is necessary to recharge MicroTymp (pg. 22) as battery voltage
has fallen below the level required for testing. The START/RUN
(bb)
button is inoperative. The MEMORY
(t
9)
buttons may be
used and data may be printed.
PRESSURE RANGE ERROR
The air pressure in the ear canal when the test began was not
correct. The MicroTymp sensed this error. To alleviate this condition,
restart MicroTymp. Should this symbol persist, return instrument
for servicing (pg. 39).
NOTE: Gradient values are computed by the Printer/Charger and
will appear at time of printout.
