Single band/Dualwatch operation
Dualwatch operation monitors two frequencies simultane-
ously. The IC-R2500 has two independent receiver circuits:
left band, and right band
(available frequencies, operating mode
and functions are different depending on bands).
Single band operation is useful when only one frequency is
being watched. The right band can be inhibited.
qSelect the left band as the main band.
➥ Push [MAIN•AGC] once to select left band, if necessary.
wPush [SET•SKIP] to enter set mode
.
ePush [SET•SKIP] or [ATT•PRIO] several times to select
“SUb” item.
rRotate the left band’s [DIAL] to turn the sub band ON for
dualwatch or OFF for single band operation.
tPush any key for main band to exit set mode
.
When the dualwatch operation is in use, IC-R2500 must be
connected to two antennas. ([ANT1] and [ANT2])
DD
Diversity operation
The diversity receiving compares the receiving signal strength
from two different antennas, ANT1 and ANT2, and automati-
cally selects the strongest signal. This feature is useful when
you are listening in a moving vehicle or the transmitting sta-
tion itself is moving. Diversity receiving is available from 50
MHz to 1300 MHz on FM, P25 and DV modes only.
qTurn the sub band OFF to select single band operation as
described at left.
wRotate right band’s [DIAL] to turn the diversity function ON
or OFF.
• With the squelch open in FM mode while receiving a
weak signal, diversity receiving does not work properly.
• AGC is disabled during diversity receiving.
