too short distance?

[MOHAX <noa...@la...>]

I've got last lirc installed and configured to work
with Pioneer CU-SX.. successfully. But the distance
lirc "understands" signals is about 80 sm or less. If
remote control is moved more then 80 sm away IR
receiver (Tekram IR-210), lircd stops to "understand"
received signals. Whereas mode2 shows, that signals are
received even if remote control is in several meters
from Tekram. Is it "know issue" or i've done something
wrong?
