COMMUNICATIONS RECEIVER

With optional UT-122

Dualwatch, Digital Mode, Diversity Receiver

Dualwatch capability

The IC-R2500 has dualwatch receive capability*1, allowing you to receive two bands simultaneously. It covers 0.013299.999 MHz in AM, FM, WFM, SSB, CW, DV*2 and P25*3 modes on the main receiver, while the sub-receiver covers 501300MHz in AM, FM and WFM modes*4.
*1 Two antennas are required for dualwatch receive. *2 Optional UT-118 required. *3 Optional UT-122 required. Already installed with some versions. *4 Frequency range differs depending on version.

Digital mode reception

The optional UT-118 D-STAR digital unit and UT-122* P25 digital unit provide the latest digital mode reception. Catch the action in digital communications!
* Already installed with some versions.
1000 alphanumeric memory channels
With Icoms Dynamic Memory Scan, DMS, you have a versatile memory channel management system at your command. The 1000 memory channels can be arranged by service or personal preference in the 21 memory banks. Selectively link the channels together to scan depending on your needs. Programming the memory channels and 6 character memory names is simple with your PC.
Diversity receive capability
The diversity receive* mode is useful for mobile operation where the received signal changes continuously. It compares the signal strength and chooses the antenna with the better signal to maintain good sound and receive quality.
* Two antennas are required. Available in FM/DV/P25 mode between 50 1300MHz only. Diversity reception is not available while using dualwatch.

Wide LCD display for independent band control
The wide LCD display shows both main/sub receiver settings in an easy-to-read symmetric side-by-side layout. The controller provides separate tuning, volume, squelch knobs and function buttons for the left (Main) and right (Sub) receivers. The LCD backlit color is selectable between amber and green for your preference.

Partial reset

POWER ON

All reset

If you want to initialize the operating conditions (VFO frequency, VFO settings, set mode contents) without clearing the memory contents, a partial resetting function is available. While pushing either bands [VFO/MRS.MW], turn the power ON to partially reset the both bands at same time.
The function display may occasionally display erroneous information (e.g. when first applying power). This may be caused externally by static electricity or by other factors. If this problem occurs, turn power OFF. After waiting a few seconds, turn power ON again. If the problem persists, perform the following procedure.
Partial resetting is also available. See left for details.

IMPORTANT!:

Resetting the receiver CLEARS all memory information and initializes all values in the receiver.

While pushing both bands [MHzTS], turn the power ON to reset the CPU.
While pushing both [MHzTS], turn power ON.

Internal audio switch

The internal switch must be toggled when using an external speaker, headphones or earphone.
CAUTION: DISCONNECT the AC adaptor or DC power
