Det-Tronics PW9200x Pathwatch IR Gas Detection System - Manual (Page 24)

If malfunctions cannot be corrected by carefully fol-
lowing the procedures described in this manual, con-
tact the factory for assistance. In many cases, suffi-
cient information to correct the malfunction can be
provided over the telephone. If it is necessary to con-
tact the factory by telephone, it is helpful to have the
operation and maintenance manual accessible and to
obtain the following readings for the service techni-
cian:
Instrument S/N ________________
Options purchased ______________________________
Measure and record the channel voltages under two
conditions:
1. Normal operating conditions
2. With the receiver window blocked with opaque
material (e.g. cardboard disk).

Both field and factory service are available from
Detector Electronics. If it becomes necessary to
return an instrument to the factory, extreme care must
be taken in packing the instrument for shipment. The
monitor should be enclosed in a plastic bag, sur-
rounded with at least two inches of foam or shipping
pellets on all sides and shipped in a heavy duty car-
ton. Lack of sufficient cushioning can cause exten-
sive damage to internal components. It is not usually
necessary to return the transmitter and, if carefully
packed, just the receiver housing cover and attached
components can be shipped.
DEVICE REPAIR AND RETURN
Prior to returning devices or components, contact the
nearest local Detector Electronics office so that a
Service Order number can be assigned. A written
statement describing the malfunction must accompa-
ny the returned device or component to expedite find-
ing the cause of the failure.
Pack the unit or component properly. Use sufficient
packing material in addition to an anti-static bag or
aluminum-backed cardboard as protection from elec-
trostatic discharge.
Return all equipment transportation prepaid to the
factory in Minneapolis.
