CALREC Putting Sound in the Picture  7
After Sales Modifications
Please be aware that any modifications 
other than those made or approved by 
Calrec Audio Limited or their agents, may 
invalidate the console’s warranty. This 
includes changes to cabling provided by 
Calrec and variations to the recommended 
installation as detailed in Calrec 
documentation.
Modifications to this equipment by any 
party other than Calrec Audio Limited 
may invalidate EMC and safety features 
designed into the equipment. Calrec Audio 
Limited can not be liable for any legal 
proceedings or problems that may arise 
relating to such modifications. 
If in doubt, please contact Calrec Audio 
Limited for guidance prior to commencing 
any modification work.
Installation
In many installations the AC power 
connectors will not be readily accessible, 
effectively making the equipment 
permanently connected. The installation 
should be carried out in accordance 
with all applicable installation rules and 
regulations.
Service Personnel
The AC power disconnect devices are 
the 2 x IEC (IEC60320-1 C13/C14) 
couplers located at the rear of each unit. 
WARNING: The apparatus has a dual 
power system. It is essential that BOTH 
AC power IEC couplers are disconnected 
to prevent exposure to hazardous voltage 
within the unit.
Third Party Equipment
Integrating third party equipment into 
a Calrec system may compromise the 
product’s ability to comply with the Class 
B radiated emission limits set in the EMC 
(Electro Magnetic Compatibility) standard 
EN55022. 
Calrec Audio Limited can not be 
responsible for any non-conformities due 
to use of third party equipment. If in doubt, 
please contact Calrec Audio Limited for 
guidance prior to integrating any third 
party equipment.
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 
anti-static wrapping upon request. 
This applies particularly to digital products 
due to the types of devices and very 
small geometries used in their fabrication, 
analog parts can, however, still be 
affected.
LEAD FREE STICKERLEAD FREE
RoHS Legislation
In order to comply with European RoHS 
(Reduction of Hazardous Substances) 
legislation, Calrec PCB and cable 
assemblies are produced with lead-free 
(tin/copper/silver) solder instead of tin/
lead solder.
In the unlikely event of a customer 
having to carry out any re-soldering on 
Apollo, Artemis or Hydra2 hardware, 
it is imperative that lead-free solder is 
used; contaminating lead-free solder with 
leaded solder is likely to have an adverse 
effect on the long-term reliability of the 
product. Circuit boards assembled with 
lead-free solder can be identified (in 
accordance with IPC/JEDEC standards) 
by a small oval logo (see below) on the 
top-side of the circuit board near the PCB 
reference number (8xx-xxx). The same 
logo is used on the connector hoods of 
soldered cable assemblies. 
If in doubt, please check with a Calrec 
customer support engineer before 
carrying out any form of re-soldering
