8. MAINTENANCE

8.1. MAINTENANCE PROCEDURES

8.1.1. Normal Maintenance. Normal maintenance is limited to periodic battery charging and

cleaning the outer surfaces and panels with a damp cloth removing dirt and debris. Ensure the

CHARGE/PROGRAM, ELECTRONIC KEY port, and firing terminals are clean and dry with a

cotton swab. Check for signs of corrosion around and on connector pins. Ensure the electric

detonator firing terminals are clean, and easy to depress.

8.1.2. Scheduled Maintenance. It is recommended that the 1673 RFD be returned to the

manufacturer or an authorized service shop every two years for periodic maintenance. At this time

the latest improvements are added, fresh battery packs are installed, the radio transceivers are

tuned and verified, and the overall performance of the RFD is thoroughly tested.

8.1.3. Corrective Maintenance. Corrective maintenance should be performed at the

manufacturer or an authorized service shop only. Replacement of parts or repair at the user level

and field disassembly is strongly discouraged and may result in death, injury, or unsafe equipment

operation. The Remote Unit contains dangerously high voltage levels when armed.

8.1.4. Battery Maintenance. Your RFD contains heavy-duty 7.2V NiMH battery packs that

should be replaced after 500 charge/discharge cycles or every three years, whichever comes first.

If a decrease in run time has developed, there may be a memory problem caused by repeated

shallow discharges or interrupted charge cycles.

8.1.5. Battery Condition (Discharge). To keep the battery packs running optimally, it is

recommended that you perform a full discharge before recharge using the discharge feature of the

at least once per month. To perform a Battery Condition, connect the Charger Power Supply to a

wall outlet, and connect the cable connector to the CHARGE/PROGRAM connector. Turn the unit

on and then press and hold the ‘BATT TEST’ switch for 5 seconds. The unit will discharge the

battery to a low level and then it will be recharged. The whole process takes up to 10 hours to

complete. Always ensure the power supply is connected and working before discharging.
