3 BASIC OPERATION ■ V/V, U/U simultaneous receive (Para-watch) The IC-2820H can simultaneously receive two signals on the same band, such as 144 MHz band, using the para-watch function. To activate the para-watch function from the HM-133, enter the desired frequencies for each the left and right bands using the direct frequency input capability via the keypad; or perform the following operation. Can be switched between VHF and UHF [Example] z Push [BAND] to select the desired band (left or ENT right) as the main band. C • Push [VFO/LOCK] to select VFO mode, if neces- sary. x Push [ENT C(T-OFF)] to activate the keypad for digit input. c Push 6 keys to input a frequency. • When a digit is mistakenly input, push [ENT C(T- OFF)] to clear the input, then repeat input from the 1st digit. v Push [VFO/LOCK] to change main band, then repeat the steps z to c for the other band. qPush and hold either the left or right band's [MAIN•BAND] for 1 sec. to select the frequency band selecting condition. wRotate the same band's [DIAL] to select the desired frequency band. e Push the [MAIN•BAND] to return to frequency indication. r Set the desired frequency. t Repeat the steps q to r for the other band (left or right). 23 NOTE: • Memory channels are common for the left and right band. • Transmitting during the para-watch operation is possible. However, the sub band's reception is deactivated during transmit as shown in the example at left. • DV mode receiving is available only one band.

BASIC OPERATION
The IC-2820H can simultaneously receive two signals on the
same band, such as 144 MHz band, using the para-watch
function.
q
Push and hold either the left or right band’s
[MAIN•BAND]
for 1 sec. to select the frequency band selecting condition.
w
Rotate the same band’s
[DIAL]
to select the desired fre-
quency band.
e
Push the
[MAIN•BAND]
to return to frequency indication.
r
Set the desired frequency.
t
Repeat the steps
q
to
r
for the other band (left or right).
To activate the para-watch function from the HM-133, enter
the desired frequencies for each the left and right bands using
the direct frequency input capability via the keypad; or per-
form the following operation.
z
Push [BAND] to select the desired band (left or
right) as the main band.
• Push [VFO/LOCK] to select VFO mode, if neces-
sary.
x
Push [
ENT
C(T-OFF)] to activate the keypad for
digit input.
c
Push 6 keys to input a frequency.
• When a digit is mistakenly input, push [
ENT
C(T-
OFF)] to clear the input, then repeat input from the
1st digit.
v
Push [VFO/LOCK] to change main band, then
repeat the steps
z
to
c
for the other band.
NOTE:
• Memory channels are common for the left and right band.
• Transmitting during the para-watch operation is possible.
However, the sub band’s reception is deactivated during
transmit as shown in the example at left.
• DV mode receiving is available only one band.
