9.2 LAMP REPLACEMENT
The lamp source (HF catalog #21084) used in the DRT-15CE has an
extremely long life. Before replacing the lamp, make certain that the battery
is not in need of a charge and is not defective. Prior to replacing the lamp,
remove the battery as described in battery replacement. Remove the lamp
wires at terminal block. To remove the lamp, loosen the two set screws on
the outermost barrel with a 5/64" hex wrench and pull the lamp straight
out. Replace the lamp in the reverse order. Make sure the lamp is pushed
all the way in. The set screws should be snugged up; excess pressure could
damage the lamp. Replace the battery. Replace the chassis in the case and
recalibrate as described in CALIBRATION PROCEDURES SECTION
7.0, page 5 in this manual.
