Following is the recommended procedure of setting the Ashtech Z12 with an external frequency source. Two separate screens need to be used: 1. Screen 4, EXT FREQ, enter "EXTERN FREQ:" in MHz. Press e to save value. 2. Screen 4, EXT FREQ, set "Save through power cycle:" to Y. 3. Screen 4, EXT FREQ, set "Auto-switch to internal" to Y if you want the receiver to operate in the event that the external frequency should fail while the receiver is still working. Set it to N if you do not want any data from the site in the absence of the external frequency reference. 4. Screen 4, EXT FREQ, STATUS field should show LOCKED, not NOT LOCKED. 5. Screen 4, RCVR CTRL, set CLOCK STEERING to N. We hope this clarifies the procedure. Please direct any questions on this procedure to Customer Support ( support@ashtech.com , 1-800-229-2400 in the US, or +1 408-615-5100 outside the US) Robert Snow Director of Reference Station Sales Magellan Corporation
