If the reception is not very clear with the
attached T-shaped FM antenna, the use of
an external antenna is recommended.
Please make sure that you comply with the
following considerations regarding the
iocation.
Keep the antenna away from noise sources
(neon signs, busy roads etc.)
It is dangerous to put it close to power
lines, so keep it well away.
Please refer to the following procedure
when connecting a 75/300 ohm antenna
adapter. (This adapter is included if your
R-811RDS is a worldwide model.)
Connecting the coaxial cable
1. Prepare the coaxial cable as shown.
2. Using your fingernail or a small screw-
driver, remove the cover.
Connect the 75/300 ohm antenna
adapter to the coaxial cable and replace
the cover.
@) Insert the end of the cable.
@ Clamp in place with pliers.
