To adjust the start pressure of the ramp on your Z1™ your ramp time must be set first.  If there is no set ramp time, a Fail 2 message will appear on your LCD display.


To set the ramp time:


1.  With the Z1™ in standby mode, press and hold the UP Arrow Button for approximately 3-5 seconds.  When "00" begins to flash, press the UP Arrow Button to select the 

     amount of time you would like the ramp feature to be engaged.  It can be set from 5 minutes to 45 minutes, in 5 minute increments.  


2.  When your time is selected, press and hold the Start/Stop Button until you see the word "Accept".  Now the ramp feature is engaged and you can proceed to set the ramp            pressure.


To set the ramp pressure:


1. With the Z1 is in standby mode, press and hold the Down Arrow Button for approximately 3-5 seconds until the 4.0 (or another pressure reading) begins to flash. 


2. While the start pressure value is flashing, repeatedly press either of the Up/Down buttons to increase or decrease the start pressure (4 is the lowest setting).


3. When the desired ramp start pressure is reached, press and hold the Start/Stop Button for approximately 3 seconds to save your setting (this setting will be saved even

     when the Z1 is not powered) . The Z1 will return to standby mode.


NOTE: To return to standby mode without saving the new setting, press and release the Start/Stop Button momentarily instead of holding it down.
