The unit will now perform a normal boot-up operation with sleep mode
enabled. With sleep mode enabled the unit will function with all the same
parameters as outlined above with one new feature. While in the ON mode, the
unit will time-out after 90 seconds to a battery saving condition. This condition
will be indicated by a crescent moon on the display. While in this condition
any key that is pressed will return the unit to the ON mode and reset the 90
second time-out counter. In sleep mode, the device will continue to monitor
the oxygen level and will activate the alarm if an alarm condition occurs.

To extend the life of the batteries a Maxtec approved external power supply
can be purchased. Once connected to the unit, total power is supplied by the
external power supply. The batteries are still required to be in the unit and will
provide emergency power in the event main AC power is lost.
