Changing the Probe
1. Turn off the GM70.
2. Detach the probe as follows (see Figure 18 below):
- Loosen the plastic probe fastener by unscrewing it about 5 turns.
- Take a firm hold from the base of the probe and pull strongly
until the probe comes loose.
3. Insert a new probe to the handle as deep as possible. Turn the probe
inside the handle until you feel that a step in the probe connector
snaps into the groove of the probe handle connector and locks the
probe.
