13			↑ and ↓ Keys- The ↑ and ↓ arrow keys are used in
			conjunction with the CALIBRATE key to calibrate the unit or in
	conjunction with the LOW SET and HIGH SET keys to adjust the alarm
	settings. When used after pressing the CALIBRATE key, pressing the ↑
	or ↓ key will raise or lower the displayed oxygen value in .1%
	increments. When either of these keys are held down for more than 1
	second, the display will scroll at a rate of .4% per second. When used
	after pressing either the LOW SET or HIGH SET keys, pressing the ↑ or
	↓ key will raise or lower the displayed alarm setting in 1% increments. In
	the alarm set mode, holding these keys down for more than 1 second
	will cause the display to scroll at a rate of 4% per second.
14			LOW SET Key- When the keypad is unlocked, pressing the
			LOW SET key will cause the "LOW" icon to flash. The low
	alarm setting can then be changed using the ↑ and ↓ arrow keys. When
	the low alarm value is set and the LOW SET or LOCK/UNLOCK key is
	pressed again, the unit exits the alarm set mode and returns to normal
	operation. The unit will also revert to normal operation (storing the most
	recent alarm value) if 10 seconds elapse and no keys are pressed. The
	OM-25ME alarm setting is adjustable down to 18%. The OM-25ME-L low
	alarm setting is adjustable to 15%.
15			HIGH SET Key- When the keypad is unlocked, pressing the
			HIGH SET key will cause the "HIGH" icon to flash. The high
	alarm setting can then be changed using the ↑ and ↓ arrow keys. When
	the high alarm value is set and the HIGH SET or LOCK/UNLOCK key is
	pressed again, the unit exits the alarm set mode and returns to normal
	operation. The unit will also revert to normal operation (storing the most
	recent alarm value) if 10 seconds elapse and no keys are pressed.
16		SILENT Key- In an alarm condition, pressing the SILENT key will
		deactivate the alarm beeper, but the alarm LED and display will
	continue to flash. In 120 seconds, the alarm beeper will sound again.
	This process will be repeated until the alarm condition is cancelled. For
	an alarm condition to be cancelled, the concentration must be .1% higher
	than the alarm setting (in the presence of a low alarm condition) or .1%
	lower than the alarm setting (in the presence of a high alarm condition).
