System Messages and Error Codes
Some other messages may be displayed that give indications of errors from
other sources (outside the unit):
Display Description

audio (perhaps a CD ROM). This message may also be
displayed briefly when the sample sample rate is changed.
Hot The unit is overheating, and performance may suffer.
Ouch The unit is seriously overheating, and may be damaged
shortly. Switch off!
Bad Fs The sample rate coming in is not one the unit can lock to,
or there is an input signal quality problem.

Trouble Shooting Your System
If you experience difficulties when using your dCS 900 / 902, the following
suggestions may help to resolve the problem.
The unit fails to power up -
• Ensure there is power available on the mains cable and the unit’s mains
switch is On.
• Check the rated supply voltage shown on the rear of the unit matches the
local supply voltage.
• Check that the fuse has not blown - if so, correct any obvious cause then
replace the fuse as described in the section “User Changeable Parts”,
page 56.
• Check that the mains cable is pushed fully home into the mains inlet in the
rear of the unit.
The audio output is low or absent -
• Check that all cables are connected correctly and not damaged. Damaged
cables are a VERY common source of malfunctions!
• Check that the source and destination equipment are switched on and
correctly set up.
• Check that an audio signal is present on one or both of the inputs.
• Ensure Mute is not enabled - LED off.
The level trimmers on the rear panel do not change the input level
• Ensure the trim tool or screwdriver you are using is narrow enough to reach
the adjuster (about 2.5mm or 0.1” diameter) and long enough (at least
12mm or 0.5”).
• The trimmer may be at the end of its travel - try turning it several times the
other way. It is a 20-turn device.
The unit slaves to Word Clock but not AES/EBU
• This can be caused by erroneous system messages. Contact your dealer or
dCS for advice.
