4.1 Unpacking

Your Compellor was packed carefully at the factory in a container designed to protect the unit during shipment. Nevertheless, Aphex recommends making a careful inspection of the ship- ping carton and the contents for any signs of physical damage.

4.2 Damage & Claims

If damage is evident, do not discard the container or packing material. Contact your carrier immediately to file a claim for damages. Customarily, the carrier requires you, the consignee, to make all damage claims. It will be helpful to retain the shipping documents and the waybill number.

4.3 Mains Voltage Selection And Fuse

Before applying power to the Compellor, it is a good idea to verify the correct mains voltage setting. This is easily determined by looking through the transparent fuse cover on the rear of the chassis.

AC Line power is supplied to the unit via an integral receptacle/fuse holder on the rear panel. This receptacle meets the various international safety certification requirements, provides the international mains power selection, and serves as a radio frequency line filter. The pro- grammed voltage can be read near the left end of the fuse clip on the surface of the program- ming card. If the incorrect voltage is seen, proceed to reprogram the voltage.

Reprogramming the mains voltage is easy if the following steps are followed. Remember to check the fuse value and install the correct fuse as indicated.
