Your Caspian preamplifier is set to operate from a fixed supply voltage which is marked on a label next to the
mains input plug. Before connecting the mains lead please check that your mains supply corresponds to this
label as below:
230V Products ………………………………….Voltage Range: 220V – 240V
115V Products ………………………………….Voltage Range: 100V – 120V
100V Products ………………………………….Voltage Range: 90V – 110V
The mains lead supplied with this product has an IEC mains socket which plugs into the IEC connector on the
unit’s rear panel. The other end is normally attached to the appropriate mains plug for your country. In the UK
this is the standard UK13A plug.
This plug should ordinarily not be removed from the lead. If you do remove it, please dispose of it safely so that it
cannot be plugged into a mains socket whilst in a potentially dangerous condition. We suggest that you obtain
from your dealer a complete replacement lead.
Should you move to another area where either the mains voltage or the mains plugs are different from those as
supplied with your preamplifier, please contact the appointed ROKSAN distributor for assistance.
Please observe correct mains polarity at all times.
The preamplifier mains fuses are located on the rear panel next to the IEC mains connector. These must only be
replaced by the fuse type and rating as described on the fuse rating label on the rear panel of the unit.
If the equipment is likely to be unused for some time, unplug it from the mains supply.

guarantee that such interference will not occur in a specific installation. If interference arises (which you can
determine by switching the unit off and on) you could try to remedy this problem by the following:
• Re-orient or re-locate the receiving antenna
• Increase the distance between the preamplifier and receiver
