3 SETTING A FREQUENCY ■ Preparation D Turning power ON/OFF [PWR• D VFO and memory modes The receiver has 2 basic operating modes: VFO mode and memory mode. Select VFO mode first to set an operating frequency. ] [VFO/MR•S.MW] ➥ Push [PWR• ] for 1 sec. to turn power ON and OFF.

[MAIN•AGC] [MAIN•NB] ➥ Push the desired band’s [MAIN•AGC] or [MAIN•NB] to select the main band. • “Q” indicates the main band.
SETTING A FREQUENCY 3 ■ Tuning step selection When using the tuning dial to change the frequency, or when a scan function is activated, the frequency changes in increments determined by the set tuning step. This can be changed if desired. eRotate the same band’s [DIAL] to select the desired tuning step. 3 The following tuning step are available. • 0.01 kHz (10 Hz) • 0.1 kHz (100 Hz) • 2.5 kHz • 8.33 kHz • 12.5 kHz • 25 kHz • 100 kHz • 200 kHz • 0.02 kHz (20 Hz) • 0.
3 SETTING A FREQUENCY ■ Using the tuning dial ■ Receive mode selection q Rotate the desired band’s [DIAL] to set the frequency. Receive modes are determined by the physical properties of the radio signals. The receiver has 6 receive modes: USB LSB, CW, AM, WFM and FM modes. The mode selection is stored independently in each memory channel. Additionally, IC-R2500 has a DV or P25 mode when the optional UT-118 or UT-122 units are installed, respectively.
BASIC OPERATION 4 ■ Receiving ■ Monitor function q Set the audio level for the main band. ➥ Push the desired band’s [MAIN]. ➥ Push [MONI•T/T-SCAN] to open the squelch. ➥ Rotate the main band’s [VOL] to adjust the audio level. ➥ Push [MONI•T/T-SCAN] to close the squelch. w Set the squelch level. ➥ Rotate the main band’s [SQL] fully counterclockwise in advance, then rotate [SQL] clockwise until the noise just disappears. eSet the operating frequency in the main band. (pgs.
4 BASIC OPERATION ■ Lock function ■ Attenuator function To prevent accidental frequency changes and unintentional function access, use the lock function. The attenuator prevents a desired signal from being distorted when very strong signals are near the desired frequency or when very strong RF fields, such as from a broadcasting station, are near your location. The attenuator reduces signal strength by about 20 dB and this function can be activated on 1300 MHz or below.
BASIC OPERATION 4 ■ NB function ■ AGC function The NB (noise blanker) function removes pulse-type noise when SSB, CW or AM mode is selected. The AGC (Automatic Gain Control) function controls receiver gain to produce a constant audio output level even when the received signal strength varies from fading, etc. A slow-response AGC function is selectable for SSB, CW or AM mode. ➥ After pushing [MAIN] to select the desired band (left or right) as the main band, push and hold [MAIN•NB] for 1 sec.

When the alert signal is detected, the “ALt” and the WX channel are displayed alternately and sounds a beep tone until the receiver controls are manipulated.
BASIC OPERATION 4 ■ Single band operation D Single band/Dualwatch operation D Diversity operation Dualwatch operation monitors two frequencies simultaneously. 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.
