  • Page 50: Priority And Block Id Codes

    CONVENTIONAL FEATURES a call is received on one of these groups, the transceiver automatically transmits a response. This causes the transceiver placing the call to briefly unsquelch and the call indicator to turn on (if it is programmed on the selected group). Priority and Block ID Codes LTR priority and block ID codes function nearly the same with both LTR and Multi-Net operation.

  • Page 51: Transmit Disable On Busy

    CONVENTIONAL FEATURES A CG (Call Guard disable) option switch may also be programmed. This switch disables both receive and transmit squelch control on the selected group only (the monitor mode disables only receive squelch control). When squelch control is disabled by the CG switch, “CG OFF” is momentarily displayed.

  • Page 52: Talk-Around

    CONVENTIONAL FEATURES Talk-Around Normally, all transmissions go through a repeater. Therefore, if you are out of radio range of the repeater, you cannot talk to anyone, even if you are only a short distance away from the mobile you are calling. To allow communication if this occurs, the talk-around feature can be used to enable direct mobile-to-mobile communication without going through a repeater.

  • Page 53: Priority Group Sampling

    CONVENTIONAL FEATURES Priority Group Sampling The priority group sampling feature ensures that messages on priority conventional groups are not missed while listening to a message on a non-priority conventional group. A fixed first and second priority group can be designated by programming or either priority group can be the selected group.

  • Page 54: Miscellaneous

    MISCELLANEOUS NOTE: Priority sampling occurs only on conventional systems and only when scanning is enabled by the SCAN switch. It does not occur when listening to a Multi-Net or LTR call or when transmitting. MISCELLANEOUS Supervisory Tones The following tones are heard at various times when operating this transceiver.
  • Page 55 MISCELLANEOUS seconds before this tone sounds, a single beep sounds to indicate that time-out will soon occur. • Transmit Inhibit - If this tone sounds as soon as the PTT switch is pressed with a Multi-Net or LTR system selected and “TX INHIB” is displayed, the transmitter has been disabled by the Transmit Inhibit feature (see page 47).
