Operating Manual

The TOT function is used to prevent a too long transmission and limits the tx time: TOT temporarily stops the transmission if
the radio has been used beyond the max pre-set time (for example 15s, 30s, 45s, etc).
(11) Receiving DCS (R-DCS) - MENU No.10
DCS codes are similar to access codes and can be added to channels, so as to create a sort of personal channel. They enable
the radio to communicate with the users that are tuned on the same channel and have set the same DCS code.
You can choose amongst:
• OFF: OFF
• R-DCS: D023N-D754N (Normal DCS)
• R-DCS: D023I-D754I (Inverse DCS)
Note: In UV5R PRO there are 208 groups of normal and inverse DCS codes. This function cannot be amended in channel
mode.
(12) Receiving CTCSS (R-CTCSS) - MENU No.11
As DCS codes, the CTCSS codes can be added to the channels for creating new private channels.
Note: there are 50 groups of CTCSS tones. In channel mode the CTCSS tones cannot be changed.
(13) Transmitting DCS - (T-DCS) - MENU No.12
In this Menu you activate DCS codes in tx mode. You can choose between normal R-DCS (D023N-D754N) and inverted R-DCS
(D023I-D754I)
Note: the groups of DCS codes are 208. DCS codes cannot be changed in channel mode.
(14) Transmitting CTCSS (T-CTCSS) - MENU No.13
In this Menu you can set a CTCSS tone in tx mode.
You can choose: OFF or CTCSS (67.0 to 254.1 Hz)
Note: there are 50 groups of CTCSS tones. In channel mode the CTCSS tones cannot be changed.
