4.  operating instructions

4.1  Key definitions

This machine consists of three buttons, keys, ↑ keys, keys (from left to right order),

keys for the power switch and play function, the key to confirm ↑ shift key, button up to scroll and digital subtract role.

 

4.2  Boot methods

Long press key 5 seconds not to put, to 5 seconds

after automatic startup, boot

After the picture show is as follows: the maximum range

 and the gas  name

 

Unit and electricity, 2 seconds later began to show

preheating countdown 120 seconds,

If you don't want to wait, click key directly into

 normal measurement interface,

Lower gas species, right now display vibration motor and buzzer, indicator

All alarm 1 times says the normal starting, if electricity shortage or detection

Less than sensor has long been the alarm went down, if this time click keys                                                   

On censored role, sound and vibration motor, lights have stopped working, but

Is the wording of "screen Alarm" are flashing, if it's electricity shortage,

Power icon flash, if can't detect sensor, display

"FAULT" the words, then click on the keys, sound and vibration

Motor, indicator continue to work. If the instrument is pump suction method, the screen

Will display pump icon, and has been in rotation, and if no pump will not display

The icon. Right for normal after the launch of the frame (display with CO, for example)
