2. As shown in Figure 9 (A), align the right side of the removal tool with the lip 
of the battery compartment.
3. As shown in Figure 9, carefully insert the tip of the removal tool (B) into the 
light guide access hole near the top of the rear housing.
4. Gently push the shaft of the tool straight into the housing until resistance is 
felt. Observe the depth as indicated by the mark on the tool.
5. If resistance is felt at a depth of 9.6 mm or less, as indicated by the depth mark 
on the tool, the tool has contacted the edge of the transceiver board ZIF 
connector. Raise the tool slightly to clear the connector.
6. Resistance felt at a depth greater than 9.6 mm means the tool is clear of the 
ZIF connector and has properly contacted the light guide.
7. When the tool is in contact with the light guide, carefully push to expose the 
light guide enough to grasp with pliers for removal from the housing.
8. To replace, insert the light guide straight into the opening in the top of the rear 
housing and push until fully seated.
