will typically resume normal operation after experiencing RFI.
If the PAK-ALERT distress alarm is affected by RFI when the respirator air
supply is turned off or the cylinder is empty, the distress alarm could be
turned off during use. If this occurs, depress the RED Manual Alarm Button
to activate the alarm.
IF THE SYMPTOMS OF RFI OCCUR, THE RESPIRATOR USER MUST
CHECK THE PAK-ALERT DISTRESS ALARM TO VERIFY THAT IT IS FUNC-
TIONING PROPERLY. IF THE GREEN LIGHT ON THE CONTROL CONSOLE
DOES NOT RESUME FLASHING IN THE NORMAL MANNER AFTER EX-
PERIENCING THE SYMPTOMS OF RFI, OR IF THE UNIT CONTINUES
TO MALFUNCTION IN ANY OTHER WAY, PROCEED TO A SAFE AREA,
REMOVE THE RESPIRATOR FROM SERVICE AND TAG FOR REPAIR BY
AUTHORIZED PERSONNEL.
Minimize or eliminate the effects of RFI by protecting the PAK-ALERT with
the following steps:
– Maintain a safe distance from a base station transmitting antenna or a
truck mounted radio antenna.
– Keep the antennas of hand held radios at least six (6) inches away from the
CONTROL CONSOLE or the SENSOR MODULE. See FIGURE 5.
