Page 28
Section 8 - Care & Maintenance
The batteries are the only user-replaceable parts in the RD 1000. Do not remove
any screws, other than the screw for the battery door. To do so will effect or void
the LTI Limited Warranty.
Temperature Range
The instrument components are rated for a temperature range of
-22º F to +140º F (-30º C to +60º C). Do not expose the RD 1000
to temperatures outside this range.
Protecting from Moisture and Dust
The RD 1000 is sealed to provide protection from normally expected field
conditions. It is protected from dust and rain, but will not withstand submersion.
If water leakage is suspected:
1. Power OFF the RD 1000.
2. Remove the batteries.
3. Air dry the RD 1000 at room temperature with the battery
compartment open.
Protecting from Shock
The RD 1000 is a precision instrument and should be handled with care. It will
withstand a reasonable drop shock. If the unit suffers from a severe drop shock,
you may need to align the tilt sensor (page 17).
Transporting
When transporting the RD 1000 in a vehicle, the unit should be secured in the
provided carrying case. The provided neck strap can be used when carrying the
RD 1000 in the field.
Cleaning
Clean the RD 1000 after each use, before returning it to its carrying case. Check
all of the following items:
Excess moisture. Towel off excess moisture, and air dry the instrument at room
temperature with the batteries removed and the battery compartment open.
Exterior dirt. Wipe exterior surfaces clean to prevent grit buildup in the carrying
case. Isopropanol may be used to remove dirt and fingerprints from the exterior.
Sighting Scope Lenses. Use the provided lens cloth to wipe the sighting scope’s
lenses and the external LCD. Failure to keep the lenses clean may damage them.
A damaged scope lens can make it difficult to see a target.
