 To enter check mode, press and hold the [MODE] button for at least 0.5 seconds. 

 The first two digits in the upper LED indicate the mode code, while the setting value is displayed in the 

lower LED. (See "Mode code list" in the check mode.) 

 Every time the UP [

] button is pressed, the number included in the mode code increases   

(a1 (A1), a2 (A2), a3 (

A3), …). 

  Every time the DOWN [

] button is pressed, the number included in the mode code decreases (b6, b5, 

b4, b3, …). 

 

The lower LED shows the value currently used to set the alarm, corresponding to the mode code. 

 Press the [MODE] button to return to the monitor mode. 

 

If the unit is left idle for 60 seconds or so (no button is pressed), it returns to the monitor mode.
