Scanning for CTCSS and DCS Tones/Codes

Note 1: Scanning for a CTCSS tone or DCS code can be done while either the Frequency Mode (VFO) or Channel Mode (MR) is selected. Only when VFO mode is selected, can the detected tone/code be saved to menu 11/10.

Note 2: CTCSS tone and DCS code scanning option can be accessed with or without a signal being present. However, the scanning process itself ONLY OCCURS while a signal is being received.

Note 3: Not all repeaters requiring a CTCSS tone or DCS code for access will transmit one back. In that case, the transmitter of a station that can access the repeater would need to be scanned. In other words, this would be done by listening to stations on the repeater's input frequency.

Scanning for CTCSS Tone

tap [MENU]       (enters MENU mode)

key in [1] [1]      (selects menu 11 [R-CTCS])

tap [MENU]       (enters menu 11 [R-CTCS] entry mode)

tap [*SCAN]      (CTCSS scanning will begin)

A flashing "CT" will be in the left status display to indicate the radio is in CTCSS scanning mode. In this mode, whenever the radio is receiving a signal on the selected MR channel or VFO frequency, the lower display will cycle through the CTCSS tones as they are being tested. Once the frequency of the received CTCSS tone is determined, the "CT" indicator will stop flashing.

tap [MENU]       (saves tone into menu 11 [VFO mode only])

tap [EXIT]          (exits MENU mode)

Don't forget to set VFO menu 11 back to OFF when the CTCSS tone is no longer required.
 
Scanning for a DCS tone
  
tap [MENU]       (enters MENU mode)

key in [1] [0]      (selects menu 10 [R-DCS])

tap [MENU]       (enters menu 10 [R-DCS] entry mode)

tap [*SCAN]      (DCS scanning will begin)

A flashing "DCS" will be in the left status display to indicate the radio is in DCS scanning mode. In this mode, whenever the radio is receiving an RF signal on the selected MR channel or VFO frequency, the lower display will cycle through the DCS codes as they are being tested. Once the bits of the received DCS code are determined, the "DCS" indicator will stop flashing.

tap [MENU]       (saves tone into menu 10 [VFO mode only])

tap [EXIT]          (exits MENU mode)

Don't forget to set VFO menu 10 back to OFF when the DCS code is no longer required.
