The error "cannot detect z (t/p) position" on the Topcon TRK-2P likely refers to a problem with detecting the Z-axis (vertical) position of the touch panel or nozzle position. This may happen if the nozzle or panel is outside the allowed operating range or if the position sensors are malfunctioning.

To resolve this:
1. Check that the control panel and nozzle are within the proper operating range.
2. Ensure there is no obstruction preventing movement.
3. Recalibrate Z-axis position if necessary.
4. If the issue continues, contact a qualified service engineer for inspection.

Page 111 To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the TRK-2P is used exceeds the applicable RF compliance level above, the TRK-2P should be observed to verify normal opera- tion.
Page 112: Requirements For The External Device
RF communications equipment and the TRK-2P The TRK-2P is intended for use in an electromagnetic environment in which radiated RF disturbances are con- trolled. The customer or the user of the TRK-2P can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the TRK-2P as recommended below, according to the maximum output power of the communications equipment.
