Caution!
Avoid transmitting at high power
(5
W) for ex-
tended periods of time to prevent overheating the
radio
(especially during 13.8 VDC operation). A
sensor in the Ff-530 monitors internal tempera-
ture and automatically reduces transmit power to
protect your radio if excessive temperatures are
reached.
If this occurs, a
blinking
"LOW" message will
be
displayed. You should stop transmitting at this
time and let the unit cool down. Continued trans-
mission will cause the protective feature to inhibit
transmission completely to protect the radio until
it has cooled down sufficiently.

ter power output. Release the PIT switch to re-
ceive.
If using a European version, press the upper
ridge of the rubber pad on the left side (just above
the PIT switch) to transmit a 1750-Hz Burst Tone
to access repeaters that require it.
If you need more power to maintain communi-
cations, you can select another power setting as
described in the box. However, we recommend
using the lowest power level necessary to main-
tain communication, so as to maximize battery life
and minimize possible interference to other sta-
tions.
Repeater Splits
The Ff-530 offers three methods to set up split
transmit/receive operation for repeaters: manual,
automatic and independently-stored tx/ rx fre-
quencies. Both manual and automatic methods
shift the transmit frequency above or below the
receive frequency by a programmable offset, pre-
set at the factory to 600 kHz (VHF), or 1.6,5 or 7.6
MHz (UHF). Note that only one offset, affecting all
split channels, can be used with the manual and
automatic methods. So when you want to store
