1 Document Scope
This document describes in engineering development terms the definition of Deckard. This document will
define the engineering platform with enough detail to meet the initial product concept while not
constraining the execution team on specific intricate design details.
This document is also a description of the functional behavior with sufficient detail in order to achieve an
accurate quotation, begin writing user guides and to begin developing test methods.
1.1 Definition of Terms
Shall – Term indicates a required element, e.g., "the unit shall play MP3 files".
Should – Term indicates a suggestion or preference, e.g., "the unit should attempt to read ID3V1 tags".
May – Term indicates an allowance, e.g., "the unit may play FLAC files".
Will – Term indicates a statement of fact. This is typically information used for clarity, such as "the unit
will be sold in France".
1.2 Notation
Requirements are divided into sub-sections based on system division and implementation conventions.
Each requirement is labeled as [Rx], where ‘R’ represents the ‘Requirement’ and ‘x’ marks the serial
number of each requirement.

8.2 Power Transitions
[R106]. The unit is in power off mode when the AC power is disconnected.
[R107]. The system shall transition from power off to standby mode (reaching an idle state ready for user
input) within 1 second upon plugging the AC power in.
[R108]. The unit should transition from off to operational mode instantly. If this is not possible the unit
shall blink certain LEDs while transitioning from off to operational mode (to be defined in the UI spec).
[R109]. The unit should transition from operational mode to standby instantly. If this is not possible the
unit shall blink certain LEDs while transitioning from off to operational mode (to be defined in the UI
spec).

[R113]. When the system transitions from off to operational mode, the last volume setting when the
system was previously in operational mode shall again be the volume setting.
[R114]. When transitioning from one source to another, the current volume setting shall persist.
[R115]. When the system transitions from off to operational mode, the volume should ramp from minus
infinity to the current volume setting in 250 ms.

minus infinity, the source should switch, and then the volume should ramp from minus infinity to the
current setting. The entire process should occur within 500 ms.
8.4 Mute State
