Before replacing the lamp module ensure that the instrument is turned off. Once you have turned off the
instrument, proceed with the following instructions:
1. Remove the lamp module from the instrument by squeezing the two side tabs on the module inward while
pulling the module out of the instrument. Pull the module away from the instrument until the in-line power
connector is exposed (about 6-8 inches).
2. Unfasten the connector by holding on to the white in-line connector and pulling the in-line connector apart.
When pulling the in-line connector apart, DO NOT hold on to the wires.
3. The new lamp module can now be connected to the instrument using the in-line power connector.
4. Feed the wire back into the instrument being careful that the wire does not get in the way of the lamp or
the lamp holder Z (on instrument). Make sure that the light bulb icon on the back of the lamp module is
upright. Press the module into the instrument until you hear it click firmly into place.
NOTE: The side tabs may need to be pressed outward until they click to secure the new lamp module.
5. If the two-side tabs on the lamp module do not click the lamp module securely in place, check that the
power wire is not obstructing the lamp module.
6. Turn on the instrument and follow the instructions in section 4.1 to re-calibrate the instrument with the new
lamp module. The instrument must be re-calibrated after lamp module replacement.
7. Resume normal operation.

2. Remove the lamp module by first pressing the side tabs inward and pulling the module out. Then unplug
the in-line lamp module connector by pulling the connector apart (see section 8.2 for complete details on
lamp replacement/removal).

instrument case (NOTE: there is a center screw on the instrument that is located under the instruction
sheet).

front of the instrument. Remove these old batteries by prying them slightly upward and sliding them out of
their holders.
6. Replace the old batteries with two coin-cell CR3032 batteries (Code No. EC-BATT3032). The positive side
of the batteries should be against the clip on the holder.
