Supplying power to the MRC-921

Equipment required:

• A 12-volt, 800-mA power pack

To use the unit outside of the U.S. or

Canada, you need a power pack

designed for a 220-volt AC outlet.

•

An electrical outlet within 6 feet (1.8 meters) of

the MRC-921 providing 110 volts AC in the

U.S. or Canada

1. Place the MRC-921 on a flat surface in a location

where the temperature will be between 50

degrees F (10 degrees C) and 110 degrees F (43

degrees C).

Plug the power pack’s connector into the

MRC-921’s power connector.

Plug the power pack into the electrical outlet.

Running the power-on self test

When you plug in the MRC-921, it performs a series

of self-diagnostic tests to ensure it is operating

correctly. These tests are indicated by flashing

patterns of the PTC and spare battery pack

light-emitting diodes (LEDs).

Refer to the “Troubleshooting”

section on page 24 for information

on possible errors.

If the MRC-921 passes these diagnostics, all the

LEDs turn off after 10 seconds, provided the unit does

not contain a PTC or spare battery pack. If any LEDs

stay lit, the diagnostics have discovered an error.
