CAUTION
RESPIRATOR SYSTEM MUST NOT BE PRES-
SURIZED WHEN BATTERIES ARE INSTALLED.
DAMAGE TO THE ELECTRONIC COMPONENTS
MAY RESULT IF BATTERIES ARE INSTALLED
WITH SYSTEM PRESSURIZED.
Respirators equipped with the PAK-ALERT with the integrated PAK-
TRACKER Locator System 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. The batteries should be replaced only by
a trained maintenance technician in a clean area known to be nonflam-
mable. 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 ashing light
will continue to ash while a fteen 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 PRESSUR-
IZED OR DAMAGE MAY OCCUR TO ELECTRONIC COMPONENTS.
2. When replacing batteries on respirators, remove the cylinder and place
the respirator in a clean, non-hazardous area.
3. Use a Phillips driver to remove the Battery Housing Cover as shown in
FIGURE 17. Carefully remove the cover and set aside.
4. Remove used batteries from battery compartment by sliding them out of
the battery compartment.
5. Install six (6) fresh new “AA” batteries of the same type. Always replace
all batteries at the same time.
The battery holder is marked with the style and orientation of the batteries
required. See FIGURE 7.
Use six (6) each of one of the following 1.5 volt AA batteries:
– Duracell
2
Alkaline MN1500
– Duracell Alkaline MX1500
– Duracell Alkaline PC1500
– Eveready Energizer
3
Alkaline EN91
– Eveready Energizer Alkaline E91.
Do not mix batteries. Verify correct orientation of batteries as shown on
label inside the battery holder.

ASSIST IN LOCATING A PERSON WHO MAY BE
IN A LIFE THREATENING SITUATION. FAILURE
TO FOLLOW THE INSTRUCTIONS FOR OPENING,
CHANGING THE BATTERIES AND RE-CLOSING
THE BATTERY COMPARTMENT MAY RESULT
IN DAMAGE WHICH COULD CAUSE FAILURE
OF THE PASS DURING A LIFE THREATENING
EMERGENCY OR COULD CAUSE A FIRE OR
EXPLOSION IN A FLAMMABLE OR EXPLOSIVE
ATMOSPHERE POSSIBLY RESULTING IN INJURY
OR DEATH.
WARNING
BATTERIES MUST ONLY BE CHANGED IN
AN AREA KNOWN TO BE NONFLAMMABLE.
