IMpOrtant InfOrMatIOn
ESD (Static) Handling
Procedures
In its completed form, this equipment has
been designed to have a high level of
immunity to static discharges. However,
when handling individual boards and
modules, many highly static sensitive
parts are exposed. In order to protect
these devices from damage and to protect
your warranty, please observe static
handling procedures, for example, use an
appropriately grounded anti-static wrist
band. Calrec will supply an electrostatic
cord and wrist strap with all of it’s digital
products.
All modules and cards should be returned
to Calrec Audio Limited in anti-static
wrapping.
Calrec Audio Limited can supply these
items upon request, should you require
assistance.
This applies particularly to digital products
due to the types of devices and very
small geometries used in their fabrication,
analogue parts can however still be
affected.

Explanation of Warning
Symbols
The triangular warning symbols below
contain a black symbol on a yellow
background, surrounded by a black border.
The lightning flash with arrow head
symbol within an equilateral triangle is
intended to alert the user to the presence
of dangerous voltages and energy levels
within the product’s enclosure that may be
of sufficient magnitude to constitute a risk
of electric shock or injury.
The exclamation mark within an equilateral
triangle is intended to prompt the
user to refer to important operating or
maintenance (servicing) instructions in the
documentation supplied with the product.
Power Supply Blanking Plates

CalrEC Putting Sound in the Picture 7
In order to comply with European RoHS
(Reduction of Hazardous Substances)
legislation, from the second week in April
2006 the vast majority of Calrec PCB and
cable assemblies will have been produced
with lead-free (tin/copper/silver) solder
instead of tin/lead solder.
This means that for a period of time
after April 2006 delivered consoles will
contain a mixture of assemblies produced
with different types of solder. This is
unavoidable due to the fact that circuit
boards are built in batches and allocated
to consoles on a ‘first in, first out’ basis
(hence the need to change the process
well in advance of the legislation coming
into force).
In the unlikely event of a user having
to carry out any re-soldering on such
assemblies, it is imperative that the correct
type of solder is used; not doing so is likely
to have an adverse effect on the long-term
reliability of the product.
rOHs lEGIslatIOn
Circuit boards assembled with lead-free
solder can be identified (in accordance
with IPC/JEDEC standards) by a small oval
sticker placed on the top-side of the circuit
board near the PCB reference number
(8xx-xxx).
The same sticker is used on the
connectors of soldered cable assemblies.
The absence of a sticker indicates that tin/
lead solder has been used. If in doubt,
please check with a Calrec customer
support engineer before carrying out
any form of re-soldering.
