CAUTION
RESPIRATOR SYSTEM MUST NOT BE
PRESSURIZED WHEN BATTERIES ARE BEING
INSTALLED. DAMAGE TO THE ELECTRONIC
COMPONENTS MAY RESULT IF BATTERIES
ARE INSTALLED WITH SYSTEM PRESSURIZED.
SCOTT respirators equipped with the PAK-ALERT distress alarm require six (6) “AA”
cell batteries for operation. The six (6) batteries power the Heads-Up Display, the
PASS device, and the PAK-TRACKER Transmitter.
NOTE
THE UNIT WILL RETURN TO THE DEFAULT ID NUMBER IF THE BATTERY COVER
IS OPENED AND/OR THE BATTERIES ARE REMOVED. SCOTT RECOMMENDS
RE-PROGRAMMING WITH THE RFID CARD IN ACCORDANCE WITH YOUR
ORGANIZATION'S PROCEDURES TO ASSURE THAT THE USER'S UNIQUE ID
NUMBER IS IN USE AT ALL TIMES.
The batteries should be replaced only by a trained maintenance technician in a clean
area known to be nonflammable.
Replace batteries as follows:
1. Close respirator cylinder valve, open regulator purge valve letting out all the
trapped air, close regulator purge valve, press the reset button twice. If there is
air pressure left in the system, the green flashing light will continue to flash while
a fifteen second beep sequence is heard from the Sensor Module as the residual
air bleeds from the system. As soon as the air has completely bled from system,
the unit will sound a quick two tone chirp and the PASS DEVICE distress alarm
will be inactive. If there is no pressure in the system when the RESET button
is pressed twice, there will be no beep sequence. If there is air pressure in the
system, the PASS DEVICE distress alarm will return to the active mode.
NOTE
ALWAYS BE SURE THAT CYLINDER VALVE IS OFF AND THE PASS DEVICE IS
COMPLETELY INACTIVE BEFORE CHANGING BATTERIES. NEVER REMOVE OR
REPLACE BATTERIES WITH SYSTEM PRESSURIZED.
2. When replacing batteries on respirators, remove the cylinder and place the res-
pirator in a clean, non-hazardous area.
3. Use a Phillips driver to remove the Battery Housing Cover. Carefully remove the
cover and set aside.
4. Remove used batteries from battery compartment by sliding them out of the bat-
tery compartment.
5. Install six (6) fresh new “AA” batteries of the same type. Always replace all bat-
teries at the same time.
The battery holder is marked with the style and orientation of the batteries required.
