Battery Low Voltage Indication

The battery level is checked when the unit is switched on.
When the battery is nearly exhausted 'bAt' is displayed before the
auto-zero procedure begins. The unit may be used when this occurs
provided the test is performed immediately. The battery should be
replaced as soon as possible.
When the battery is completely exhausted the unit will beep twice and
turn itself off immediately after turning on.
Note: If the respiratory pressure meter is not used for long periods,
the battery should be removed to prevent damage to the instrument
by possible leakage.

Battery Replacement

Locate the sliding cover situated on the rear of the unit, towards the
bottom of the device.
Place your thumb over the round thumb indent, press gently and slide
the cover to the right to remove it from the unit.
Lift the old battery out, and holding the battery terminal by the plastic
body, pull it off the old battery.
Plug the new battery into the battery terminal, taking care that the
correct polarity is observed.
Push the battery back into the battery holder, and replace the battery
cover onto the guides. Slide the battery cover to the left until it is
fully in place.
Note: Please remove the battery if the meter is likely to be unused
for some time.
CAUTION: Do not open the battery cover when the device is turned
on.
