Not sure if this will help. Manual states, that upto 8 probes can work in the same environment or shop.

To change the channel or re-pair the wireless code matching on a GP-800 wireless CNC touch probe (V2 / 2.4G system), follow the code-matching and DIP switch procedure:
Code Matching and Channel Setup Steps
1. Set the Receiver Frequency Band: Adjust the code paddle / DIP switch on the receiver to your desired frequency band or channel.
2. Power Off the System: Turn off the power to the receiver, and remove or disconnect the battery underneath the probe.
3. Trigger the Probe: Reinsert or connect the battery on the probe, then trigger the probe 4 times within 2 seconds. All probe indicator lights will turn on.
4. Power On the Receiver: Turn the receiver power back on.
5. Activate the Receiver: Turn on/activate the receiver function.
6. Press the Paddle Switch: Press the paddle switch; the probe's blue light will turn on to confirm successful code matching.
7. Reset Power: Power off the receiver, and disconnect/reconnect the battery under the probe.
8. Establish Communication: Power the receiver back on to re-establish wireless communication on the new channel.
Are you trying to resolve interference from another machine or set up multiple probes in the same workspace? Let me know so I can help adjust the DIP switch configuration.

interference from another machine
To fix cross-talk and signal interference from another nearby machine, you must change the physical channel (frequency band) on the receiver before sync-pairing the probe back to it.
Because the system allows up to 8 probes / multiple receivers to operate independently in the same workshop, shifting to a clear frequency channel will completely block out the other machine's signal.
1. Change the Frequency on the Receiver
1. Locate the code paddle / DIP switches on the GP-800 receiver unit.
2. Change the position of the switches to a completely new combination. Ensure this combination is unique and different from the machine causing the interference.
2. Force the Probe to Pair to the New Channel
Once the receiver is set to its new channel, you must force the probe to seek it out:
1. Power Everything Off: Disconnect power to the receiver box, and physically pull the battery out from underneath the probe housing.
2. The "Trigger 4x" Re-pair Window: Reinsert the battery into the probe. Immediately trigger (deflect) the probe stylus 4 times within a 2-second window. If done correctly, all indicator lights on the probe will lock on.
3. Power On the Receiver: Turn the power to the CNC receiver back on.
4. Link the Signal: Press the hardware paddle switch on the receiver. The probe’s blue LED light will illuminate, indicating that it successfully latched onto the new interference-free channel.
5. Cycle the Power: Turn off the receiver, cycle the battery on the probe once more, and power the receiver back up.
Wireless communication is now completely isolated onto your newly assigned frequency band.
If the probe still falses or triggers randomly after changing the channel, are the machines sharing a common power supply line, or are you seeing an Alarm / Error light illuminate on the receiver box?
