Operation Manual

1 STANDBY: With the rear panel POWER switch set to ON position, press this
button to switch ON the C 725BEE from standby mode. The Standby LED
indicator will turn from amber to blue and illuminate the VFD. Pressing the
[Standby] button again turns the unit back to standby mode.
The C 725BEE can also be switched ON from standby mode by pressing
any of the front panel buttons.
2 STANDBY LED: This indicator will light up amber when the C 725BEE
is in standby state. When the C 725BEE is at ON state, this indicator will
illuminate blue. When infrared command from the SR 8 is received, this
indicator will also ash momentarily.
In cases of serious abuse of the C 725BEE, such as excessively low
loudspeaker impedance and short circuit, the C 725BEE will engage its
Protection circuitry, indicated by the Standby LED turning from blue to
red and the sound being muted. At Protect mode, the Standby LED in
red color will ash and “Protect!” shown ashing also in the VFD. In the
case of overheating, the Standby LED in red color will ash and the VFD
turned o.
In such a case, turn the C 725BEE o by the rear panel POWER button,
wait for it to cool down and/or check the speaker connections,
making sure the overall loudspeaker impedance doesn’t go below 4
ohms. Once the cause for the protection circuitry to engage has been
removed, switch ON the rear POWER button and the Standby Button to
resume normal operation.
3 BLEND: The NAD BLEND feature will allow you to reduce the amount of
noise and hiss but still retain some level of stereo separation, instead of
mono. The BLEND button toggles between engaging and disengaging
the BLEND feature. When engaged, “Blend On” is shown at the lower line
of the VFD; “Blend O” when not active. The “Blend On” or “Blend O”

AM or FM frequencies. Press and release [TUNE ] to search up or
down - the C 725BEE will stop at the next suciently strong signal it
encounters. Note that this function “wraps” – that is, it will continue to
search from one end of the AM or FM band to the other until it stops
at a strong signal. Pressing [TUNE ] during the search process will
stop the search. Refer also to “OPERATION – LISTENING TO DAB RADIO”
