2. Reset the alarm using POWER MODE or AIR once the alarm condition clears if LATCH is
set to ON (factory setting) in Maintenance Mode.
If Password Protection is turned On (factory setting is Off) using the 04 Series Setup
Program, you must press POWER MODE and AIR at the same time and then enter a user-
set password to reset an alarm condition. When the password screen appears, adjust each
digit with the AIR button and press and release the POWER MODE button to move on to
the next digit. Once the password is entered, the alarm condition resets.

you may need to replace the sensor.
5. If the over range condition continues after you replace the sensor, contact RKI Instruments,
Inc. for further instructions.
Responding to Battery Alarms
WARNING: The HS-04 is not operational as a gas monitoring device during a dead battery
alarm. Take the HS-04 to a non-hazardous area and replace the batteries as
described in “Replacing the Batteries (Alkaline or Ni-MH)” on page 71.
The HS-04 is fully functional during a low battery warning. However, only a couple of days of
operating time remain. The amount of time depends on LCD backlight use and alarm frequency.
Replace the batteries as described on page 71 as soon as possible.
NOTE: Alarms and the LCD backlight consume battery power and reduce the amount of
operating time remaining.
Responding to Sensor Failure Alarms
1. Calibrate the sensor as described on page 43.
2. If the sensor failure continues, replace the sensor as described on page 78.
3. If the sensor failure condition continues after replacing the sensor, contact RKI Instruments,
Inc. for further instructions.
