General Transmitter Care Instructions
Periodically clean the spring and threads inside the battery compartment as well as the spring
and threads of the battery end cap to ensure a proper power connection with the batteries.
Use an emery cloth or wire brush to remove any oxidation that has built up. Be careful not to
damage the battery cap O-ring; remove it while cleaning if necessary. After cleaning, use a
conductive lubricant on the battery cap threads to keep it from binding in the battery
compartment.
Note All DCI battery-powered transmitters are shipped with a nickel-
based anti-seize lubricant on the battery end cap, which aids in
electrical grounding for better battery performance.
Before use, inspect the battery cap O-ring for damage that may allow water to enter the
battery compartment. Replace the O-ring if the one installed becomes damaged.
Ensure the sensor ports in the fluid pressure transmitter remain open and free of debris.
Clean with running water after every use. DO NOT use high-pressure fluid to clean the
sensor ports.
Placing tape around the fiberglass tube of the transmitter, if space allows, will keep the
fiberglass protected from most corrosive environmental wear.
HDT and FPT transmitters have a threaded hole (1/4”-20 thread) in the battery cap to allow
the use of an insertion/extraction tool for installing and removing the transmitters in end-load
housings. Ensure that this hole remains clear of debris.

Do not store the battery pack in a fully discharged state.
Do not store the battery pack in the battery charger.
If the battery pack will be stored for an extended period of time, pre-charge the battery to
a charge level of 30% to 50% (two or three LEDs illuminated on the battery pack). Do not
store the battery pack for more than one year unless it is periodically recharged to the
30% to 50% level.
