Units with operating altitudes rated at 50,000 and higher have a limited one-year warranty on the pressure sensor, while the balance of the electronics are covered under a 42 month warranty, not to exceed 60 months from the date of purchase.

Do NOT send this unit to a distributor or retailer for repair. Contact the factory directly if you experience problems (818) 787-1221.

This warranty applies to the original purchaser of the instrument and is NOT transferrable. Trans-Cal’s obligation under this warranty is limited to repairing or replacing any unit returned to Trans-Cal during the life of this warranty provided:

For the above warranty to become effective, the registration card found in the unit's install manual must be completed and returned to Trans-Cal Industries, properly filled out and signed by the dealer selling or installing this equipment.
