ISR Specifications

• UHF-FM• 14 Channels• 38 Group Codes

5

ISR Utilization Policy

• ISR frequencies are used by other military and federal users on a shared basis.– While chances of conflicting with another

agency are small, be aware that there may be other users of the frequencies.

• ISRs are not to be used from aircraft.– The ISR is intended to be a short-range

radio. If it is used in an aircraft, its range increases dramatically and may interfere with other users.

6

ISR Utilization Policy(Continued)

• Standard CAP radio procedure will be used.• Call signs will be used at all times and will be

assigned by appropriate leaders.• ISRs will normally be used with tactical call

signs (ex. Ground Team 2, Unit 1 or TC650 Unit 1)

7

The ISR’s Range

• The ISR is a short-range radio. It covers different areas in different terrain:– In wide areas free from obstruction, it has

its highest range (up to 2 miles)– When there are large buildings or trees in

the operating area, it covers a medium range.

– In mountainous areas or areas with heavy foliage, it covers a minimum range.

8

The Batteries

• The ISR operates on three AA batteries. To install:– Open the latch at the bottom of the back of

the radio– Lift the battery cover from the bottom and

pull out.– NEVER leave batteries in the radio when the

radio is not being used for more than a few days.

9

The ISR Antenna

• The ISR’s antenna rotates behind the radio for easy transportation.

• NEVER operate the ISR without FULLY EXTENDING the ANTENNA.

10

Turning ThingsOn And Off

• On the ISR, follow the same process to turn a feature on and off. For example, you do the same thing to:– Turn the radio on and off– Open and close the squelch– Lock the keypad– And more

11

Turning TheISR On/Off

• To turn the ISR on or off, press and hold the POWER button on the front of the radio.

12

Volume Control

• The volume knob is located on the right-hand side of the top of the radio.

• When setting the volume level: Press and hold the MODE button for one second or until you hear static. This will open the squelch and allow you to set the volume to a comfortable level. Once volume is set, press MODE again for one second until the squelch is closed.

13

ISR Display

• When first turned on, the ISR display shows these basic elements:– Radio Symbol (A)– Channel (B)– Group Code (C)

14

Radio Symbol

• The Radio Symbol, shown in red, indicates that the radio power is on.

15

Channel Number

• The Channel Number, shown in red, indicates what channel the radio is currently operating on. The ISR has 14 channels.

16

Group Code

• The Group Code, shown in red, indicates which group code the radio is currently operating on.

• If the Group Code is disabled, two dashes appear in place of a number.

17

Group Codes

• The ISR has 38 group codes. Group codes, or tones, are transmitted along with your signal and allow only other radios on the same group code to receive your transmission.

• In order to operate properly, all the radios in a net need to be operating on the same channel and group code.

18

Changing Channels

• To change the channel on the ISR, press the UP or DOWN buttons until the desired channel appears on the screen.

19

Changing Group Codes• To change the group code on

the ISR:– Press the MODE button to

enter Group Mode. The Group Code will flash.
