An IR Emitter Input is provided that allows

modulated IR remote control commands to be

received electrically by the unit. An RS232 port

is also featured which allows the 551R V2 to be

controlled by C.I. systems.

In addition the unit features 'direct' IR/Control codes as well as toggle codes

for some of their features to simplify programming custom installation

systems. Special direct On/Off and Mute commands can be accessed on the

supplied remote control for teaching into C.I. systems as follows:

1. Press and hold the Standby/On button on the remote control. The remote

rst generates it's standby (toggle) command. Keep the button held down,

after 12 seconds an AV receiver "On" command will be generated. If the

button is kept held down for a further 12 seconds, an AV receiver "Off"

command is generated.

Repeat this procedure with the Mute, Sub On/Off, Stereo Mono and Tuner

AM/FM buttons to send On/Off commands. The Tuner AM/FM button also

provides unique FM and AM commands to allow switching to a specic band.

A full code table and RS232 protocol for this product is available on the

Cambridge Audio website at www.cambridge-audio.com.

The 551R V2 has a function that preserves the preset memory and other

settings. In the event of a power failure, or if the power cord of the unit

is disconnected from the mains outlet, the back-up memory will preserve

the preset memory for approximately one week. If the power supply is

interrupted for 7 days or longer, the memory settings will be erased.

If it is desired to reset all settings to their factory defaults (or in the unlikely

event that the unit locks up due to an electrical discharge etc), with the unit

on and out of Standby mode press and hold the Tuner FM/AM and Analogue

Stereo Direct buttons on the front panel for three seconds.

"RESET" will appear briey on the front panel display before returning to

Standby mode.
