The tone squelch opens only when receiving a signal containing a matching subaudible tone. You can silently wait for calls from group members using the same tone in an amateur band.
SUBAUDIBLE TONE OPERATION 8 ■ Pocket beep operation ■ Tone scan This function uses subaudible tones for calling and can be used as a “common pager” to inform you that someone has called using the same tone in an amateur band while you were away from the receiver. The receiver can detect the subaudible tone frequency in a received signal. By monitoring a signal that is being transmitted on a frequency, you can check the tone frequency required to access the repeater or to open the tone squelch.
9 DUPLEX OPERATION Duplex communication uses 2 different frequencies for transmitting and receiving. Generally, duplex is used in communication through a repeater, some utility communications, etc. During duplex operation, the transmit station frequency is shifted from the receive station frequency by the offset frequency. Repeater information (offset frequency and shift direction) can be programmed into memory channels. (p. 12) This function is not available in the broadcast band (0.495 – 1.
OTHER FUNCTIONS ■ Set mode D Set mode items Set mode is used for programming infrequently changed values or conditions of functions. In addition, this receiver has an expanded set mode which is used for programming additional infrequently changed values or conditions of functions. When turning OFF the expanded set mode, only a quarter of the set mode items are displayed for simpler operation. D Expanded set mode ON/OFF q Push [V/M] for 2 sec. to enter set mode.
10 OTHER FUNCTIONS ■ Dial select step ■ Beep tones This receiver has a 1 MHz tuning step for quick frequency setting. This dial select step can be set to 100 kHz, 1 MHz or 10 MHz steps, as desired. The confirmation beep tones, which sound each time a switch is pushed, can be turned ON or OFF, as desired. This function is not available to the broadcast band (0.495 – 1.620 MHz) except for U.S.A. and Canada versions. q Push [V/M] for 2 sec. to enter set mode. w Rotate [DIAL] until “BEEP” appears.
OTHER FUNCTIONS 10 ■ Auto power-off function ■ Monitor switch action The receiver can be set to automatically turn OFF after a specified period in which no switch is pushed. The monitor switch can be set as a ‘sticky’ switch. When set to the sticky condition, each push of [SQL] toggles the monitor function on and off. 120 min., 90 min., 60 min., 30 min. and OFF can be specified. The specified period is retained even when the receiver is turned OFF by the auto power-off function.
10 OTHER FUNCTIONS ■ Dial speed acceleration ■ Lock function effect The dial speed acceleration automatically speeds up the tuning dial speed when rotating the [DIAL] rapidly. The lock function prevents accidental frequency changes and accidental function access. q Push [V/M] for 2 sec. to enter expanded set mode. w Rotate [DIAL] until “SPEED” appears. While the lock function is ON, [POWER], [VOL] and [SQL] can still be accessed. Accessible switches can be set to 1 of 4 groups in expanded set mode.
OTHER FUNCTIONS 10 ■ Channel indication mode ■ Cloning function Channel indication mode is used to simplify operation. In this mode only pre-programmed memory channel numbers are displayed and functions are limited ([POWER], [SQL], [VOL], [LOCK], scanning and the tuning dial are functional). The IC-R2 has receiver-to-receiver data cloning capability. This function is useful when you want to copy all of the programmed contents from one IC-R2 to another. An optional OPC-474 CLONING CABLE is required.
