Instruction manual

The Counter contains a lithium c-cell. The contents of the battery are
considered hazardous materials and should be treated as such.
Special attention should be given to the Rear Panel of the detector as follows.
The interior of the Battery Holder should always be kept dry. The Battery
Holder Cap has an O-ring, making the Battery Holder water-resistant, so
special care is needed only when changing the batteries. The AudioLarm
sounder is water-resistant also, but its life will be extended after exposure to salt
water if it is rinsed with fresh water and dried. The external Electronics
Connector, and Power Connector, if so fitted, will not allow water past them
but may corrode. To minimize the risk of corrosion of their electrical contacts,
the connector(s) should be rinsed with fresh water after exposure to salt water.
Do not allow water to enter the vent or desiccant tubes.
The desiccant cartridge or desiccant material must be changed before the
desiccant material is completely exchausted. To replace the “SPEEDAIRE”
desiccant dryer cartridge, simply unscrew the cartridge from the pipe fittings at
each end and replace with a fresh cartridge. (IMPORTANT Be sure to remove
the orange plugs from the ends of the cartridge before installation). Cartridges
are available through NMT or directly from Grainger, Inc. (www.grainger.com; 1-
800-323-0620; part no. 6ZC63; ~$12 for a package of 2 cartridges).
“DRIERITE” Indicating Desiccant is available from VWR Scientific Products at 1-
800-932-5000. The 5 pound jar of desiccant catalogue number 22891-040.
Each desiccant cartridge holds 1.25 pounds. Neglecting to change the desiccant
can result in irreversible damage to the electronics.
Some agencies have fitted their detectors with custom desiccant cartridges.
Please follow your agency's maintenance recommendations.
Although the Detectors are very sturdy, they are precision electronic instruments
and should be treated as such. To minimize weight, lightweight aluminum
honeycomb is used for the Detector sides and top and bottom panels. Protect
these skins from sharp objects. Rough handling, dropping, or applying a large
weight or force can damage both the exterior and the instrumentation inside. To
avoid possible damage to the controls and to the waterproof seal at the ends of
the tunnel, the R-Series should not be stood on end, but should always be
supported on its side, top, or bottom. New R-Series Detectors have a caution
label on the top that reads: Caution! This R Detector is a delicate instrument
and can be damaged by mild mechanical shock or impact! For example,
dropping one end by 4 inches onto a hard surface can cause damage requiring
