Changing the Target Gas
The target gas can be changed when turning ON the power for a
model of two-gas type (XP-702III-A(S) or XP-702III-F(S)). Either
“GAS1” or “GAS2” will be displayed on the LCD as the target gas.
To change the target gas after the power is already ON, turn OFF
the power once.
Silent Mode (No Operation Sound)
Press the buzzer button for 3 seconds while the power is ON to
enter silent mode.
In silent mode, the operation sound and alarm buzzer will not
function and the operation sound and alarm sound indicators on
the LCD will not be displayed. However, the error alarm buzzer
and battery alarm buzzer (in unusable state) will sound. (Refer to
Error Displays on page 15 and to Battery Replacement on page
18.)
To release silent mode, press the buzzer button for 3 seconds.
The alarm buzzer cannot be turned ON or OFF unless silent mode
is released. (Refer to Deactivating the Alarm Buzzer on page 14.)

For a model of one-gas type (XP-702III-B(S)), the
target gas is not displayed and it cannot be changed.
In silent mode, the Gas Leak Detector produces no
sounds at all except for errors and the battery alarm.
It will be impossible to confirm operation audibly.
Avoid using silent mode unless it is absolutely
necessary, and make sure to release silent mode
after use.

Silent mode will remain in effect even when the power
is turned OFF unless silent mode is released or unless
