Maintenance

The Pictor requires no regular maintenance.

If the unit's surface becomes dusty, simply wipe it off with a soft dry cloth. Do not spray cleaners on the sur-

face. To clean fingerprints from the surface of the preamp or power supply, spray a small amount of mild

window cleaner such as Windex onto a soft dry cloth, then use the cloth to remove the fingerprints. Do not

spray the cleaner directly onto the amplifier.

Unit will not turn on

1. First, check to see if the rear master power switch on the power supply is on. If it is, try the following steps

in order. After you perform each step, touch the touchscreen on the front of the unit. If it illuminates, the unit

is functioning correctly and there is no need to continue to the next steps.

A. Check power cable connections between the wall and the Pictor. Push the wall plug and the connector

at the power supply in firmly.

B. If the Pictor is plugged into an AC line conditioner, make sure the line conditioner is turned on.

C. Flip the master power switch off and on again. This will reset the Pictor's internal circuit breaker.

D. Check the circuit breaker for the AC circuit that the Pictor is plugged into. If the breaker is tripped, flip

it back on. If it will not turn on, there is likely a short circuit somewhere in the lines or in a device connect-

ed to this AC circuit. Check the power cords for your components to make sure none have been damaged.

E. If none of these conditions restores power, it is possible one of the Pictor's internal fuses is blown. Do

not attempt to change the fuse yourself—the Pictor requires the use of special high-voltage fuses that are

not commonly available. Contact your Constellation dealer.

Unit is on but no sound is produced

1. If the front touchscreen is blank, touch it. If it illuminates and shows anything other than the onscreen Pow-

er button, the unit is on. If it shows the onscreen Power button, touch the button to power up the unit.

2. If the front touchscreen shows the message "Powering On," wait about 10 seconds. Once the unit is

warmed up, an input screen should appear and the sound should come from the speakers or headphones.

3. If the volume numbers on the LCD panel are flashing, hit the Mute button on the front panel or on the re-

mote to restore sound.

4. If none of the above steps restores the sound, try the following steps in order. If any one of the steps re-

stores the sound, there is no need to continue to the next steps.

A. Check you are on the correct input. Cycle through available inputs using the front touchscreen con-

trols, or select the desired input using the remote.

B. Check that the source component is on and playing back—i.e., if it is a CD player, make sure that the

CD is playing and not in pause mode.

C. Check the connections between the Pictor and your amplifier(s), and between the Pictor and the audio

source device. If a cable is disconnected, reconnect it. If this does not restore sound, try substituting a dif-

ferent set of cables in order to make sure the original set was functioning properly.

D. Check that the volume is at a sufficient level. Do not turn the volume all the way up to check this, as if

sound is reestablished while the Pictor is set to output maximum volume, damage can be done to your

speakers and amplifiers.

E. If none of these actions restores the sound, contact your Constellation Audio dealer.
