No-Charge Upgrade to any owner of a CZ21 with a date code earlier than 0409xxxxx.
Detectors dated 0309xxxxx(March 2009), and earlier are eligible.
Rules:
1. Customer pays to ship detector to El Paso.
2. Fisher ships the detector back to customer, freight pre-paid.
3. Fisher changes the housing and front panel to a new heavy-duty reinforced plastic.
4. Fisher will verify the detector's calibration settings, and adjust if necessary.
5. The upgraded unit will have a new serial number, but the warranty start date will remain the same as the original purchase date.
6. If the unit returned to Fisher has lights on the front panel, the upgraded unit will not have lights.
7. Non-warrantable damage to detector is not covered.
This is a highly recommended upgrade to ensure your CZ21 lasts well beyond the warranty period.
