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)
