REPEATER OPERATION ■ Repeater operation Repeaters extend the operational range of the transceiver by retransmitting the received signals. They are usually located on the top of a building or a mountain, as the elevation increases their effectiveness, allowing the user to transmit and receive over greater distances.
SCAN ■ Scan types The transceiver has 5 scan types, a Tag function and 4 Resume options, for scanning versatility. The transceiver can scan a maximum of 80 Tag channels in approximately 1 second. Open Scan Repeatedly scans all Tag channels in sequence. ch 1 ch 2 ch 3...
SCAN ■ Scanning preparation The transceiver scans all Tag channels when a scan other than the Dynamic Group Scan is activated. In the Dynamic Group Scan, the transceiver scans only Tag channels in the zone that you select. (p. 4) When the transceiver finds a busy channel, it can be set to pause or to resume after a pause.
SCAN ■ Scanning preparation D Scan Resume function Open the “Scan Resume” screen. [MENU] > Settings > Scan Resume Push [▲] or [▼] to select a Scan Resume option, and then push [ENT] to set it. • 5sec: Scan pauses for 5 seconds when a signal is detected, and then resumes.
SCAN ■ Group Scan and Priority Scan The Group and Priority scans repeatedly look for a signal on the Priority channel while scanning the specified channels. You can use these scan modes when waiting for a call on the Priority channel or several specified channels. The Group and Priority scans are performed differently when transmitting.
SCAN ■ Dynamic Group Scan The Dynamic Group Scan can instantly detect a signal that a group member transmitted by scanning the Tag channels in the Dynamic Group Scan. The transceiver transmits on the last channel that a group member used. If the transceiver detects a signal on the channel with no code, or a code that is different from the code set in the transceiver, the transceiver searches for another channel that is not being used, and start communicating.
SCAN ■ Repeater Scan The Repeater Scan is used not only to search for a signal on the repeater channels, but also to access a repeater by automatically transmitting in sequence. The Repeater Scan detects repeaters that can be accessed in the area, even if the repeater is not used. NOTE: The Repeater Scan detects signals only on repeater channels 1 to 8 and 41 to 48.
TONE SQUELCH AND POCKET BEEP NOTE: CB channels 5 and 35 are for only emergency use. The Tone Squelch or Pocket Beep function is not selectable on these channels. ■ Tone Squelch The transceiver is equipped with 51 CTCSS tone frequencies and 104 DTCS codes. The CTCSS/DTCS operation enables you to communicate in the silent standby mode because you will only receive calls from group members using the same CTCSS tone frequency or DTCS code.
SELCALL (Selective Calling) In addition to the Tone Squelch function for silent standby, you can use the Selcall (Selective Calling) function. For the Tone Squelch function (Group mode), there are 51 tone or 104 code options when making a call. The Selcall has 100,000 options when using 5 tone.

SELCALL (Selective Calling) ■ Quiet mode When the Quiet mode is turned ON, the Selcall Mute function is activated and allows silent operation until receiving a Selcall. Open the “Quiet Mode” screen. [MENU] > Quiet Mode Select “On,” and then push [ENT] to turn ON the Quiet mode.
OTHER FUNCTIONS ■ Smart Ring and ATS (Automatic Transponder System) These functions have an answer back feature and confirmation function for when a call has reached the called station, even if the user is temporarily away from the transceiver. Smart Ring is a manual confirmation, and ATS is automatic. D Smart Ring Set the same CTCSS tone frequency to all Group transceivers, and then turn ON the Tone Squelch function.
OTHER FUNCTIONS ■ RX frequency (For receive channels) The receive channel frequencies can be set to between 400 and 520 MHz. D RX channel setting The receive channels are set to “Disabled,” and are not displayed on the screen as the default setting.
OTHER FUNCTIONS ■ Scrambler function The Scrambler function supports encrypting the communication data. You can select a subcarrier using this function. Open the “Scrambler” screen. [MENU] > Settings > Scrambler Push [▲] or [▼] to select a subcarrier between 1 and 3 to turn ON the function, and then push [ENT] to set it.
Data programming can be done to or from a PC, using the CS-455 programming software and the optional OPC-1122U (USB type) programming cable. L Refer to the CS-455 programming software’s Help file for details. IC-455 to a USB port to the Microphone connector...
SET MODE ■ Set mode You can change various common settings for the transceiver or individual settings for the operating channel in the Set mode. Essentially, you can customise the transceiver to suit your preference and operating style.
