Matters need attention
A. Please read this instruction manual before using the detector.
B. The detector must be used in compliance with the designated procedures of our company.
C. The warranty period of this transmitter is 12months (starts from the date userget the detector).
Users should comply with the instructionsin the use of this detector. Any damages or malfunctions
caused by improperoperation of users are not within the scope of warranty.
D. Repairand replacement of any parts must be operated by trained sta
ff u
nder authorization of
our company, using original spare part. The operatoris responsible for the liability if users operate
the repair of replacement by themselves.
E. There is acid solution inside the transmitter, please do not disassembleit. And pay attention not
to damage the frontal membrane of the transmitter. If the skin is stained with the acid solution. the
right remedy is to flushing the stained skin continuously with clean water for 1 0minutes.
F. The detector must be calibrated for once each year. The explosion proof sheet parts of the
transmitter need to be cleaned regularly (blow with low pressure compressedair), otherwise the
detection sensitivity will be a
ff
ected by the dust and impurities clogging protection hole.

Settings of Remote Control
The remote control applied to all product type produced by Yuante.
1. Press "MENU" once to enter F01, address code setting menu. Press "OK" to modify, press"+""-
"to modify address code of the detector. Press "OK" to save settings and "BACK" to cancel.
2. Press "MENU", then press “+”to enter F02, minimum value setting menu of gas alarm, Press
"OK" to modify, press"+" "-"to modify the value. Press "OK" to save settings and "BACK" to
cancel.
3. Continue to press "+"to enter F03, maximum value setting menu of gas alarm., Press "OK" to
modify, press"+" "-"to modify the value. Press "OK" to save settings and "BACK" to cancel. Same
operation with F04 (zero point calibration), F05 (range calibration), F06 (AD value).
4. Press "MENU" four times to enter a shift status, under this status:
Press "RESET" once, the data would be 255, one more it would be 0. Just press "RESET" to shift.
When the data is 0, press "+"or"-"to modify alarm point, the data di
ff
erence would be only 1. When
the data is 255, press "+"or"-"to modify alarm point, the data di
ff
erence would be 1000. "RESET"
can also be used as mute button when it is alarming.
