2.1 Achieving the Best Performance
To achieve the best performance:
•Use only good quality connection cables (we recommend Kramer high-
performance, high-resolution cables) to avoid interference, deterioration in
signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
•Do not secure the cables in tight bundles or roll the slack into tight coils
•Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
•Position your Kramer VS-41HC away from moisture, excessive sunlight and
dust

3.2 Using the IR Transmitter
You can use the RC-IR3 IR transmitter to control the machine via the built-in IR
receiver on the front panel or, instead, via an optional external IR receiver (Model:
C-A35M/IRR-50). The external IR receiver can be located up to 15 meters away
from the machine. This distance can be extended to up to 60 meters when used
with three extension cables (Model: C-A35M/A35F-50).
Before using the external IR receiver, be sure to arrange for your Kramer dealer to
insert the internal IR connection cable (P/N: 505-70434010-S) with the 3.5mm
connector that fits into the REMOTE IR opening on the rear panel. Connect the
external IR receiver to the REMOTE IR 3.5mm connector.
