Before Setting Out…

Inspecting Your MOON 371

Carefully remove the unit from its packaging. Visually inspect it, and in the case of damage, report it to your MOON retailer immediately.

The packaging materials were designed to protect this product while in transit. Store these materials in a dry location for the duration of the warranty period.

The information contained in this guide is subject to change without notice. The most recent version is available at simaudio.com/guides-downloads.

The MOON 371 includes:

• MOON CRM-4 remote control

  • battery compartment token

  • carrying pouch

• AAA batteries (2)

• quick-start guide

Note the serial number of your MOON 371 for future reference.

Installing Your MOON 371

Carefully consider the location and environment of your installation.

Set the 371 upon an open, stable, and flat surface. The device requires sufficient space above and around it to adequately disperse the heat it generates. Maintain a minimum gap of 5 cm (2”) around the sides and 10 cm (4”) above of the unit to enable airflow.

The performance of this device will continue to improve during the first 100 hours of listening. The spirit of this recommendation is to temper expectations and delay your first critical listening session until after all the components in the circuit have stabilized. But that doesn’t mean you can’t enjoy it from the very first note. It just means that it’ll behave most consistently after a few weeks of listening.
