TID Electronic TD831G Two-Way Radio

Time-Out-Timer (TOT)

The TOT function is used to prevent a too-long transmission and to keep the transmitter from continuous transmission if the radio has been set beyond the max pre-set time (for example 15s, 30s, 45s, etc.). Note: If this option is used to OFF, press and hold the PTT key to keep the transmission.

Dual Watch Operation (D.Waith)
When this function is activated, you can receive the frequency of channel A and channel B at the same time. If a signal is detected, the A position will break off to the corresponding channel or frequency. Note: In Dual Watch operation mode, you can change the parameter of the AB channel or frequency freely.

Receiving DCS (Rx DCS)

DCS codes are similar to access codes and can be added to channels, 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 among:

• Off
• DCS23-DCS754N (Normal DCS), DCS23-DCS754I (Inverse DCS)

Note: In radio, there are 208 groups of normal and inverse DCS codes. This function cannot be amended in channel mode.

Receiving CTCSS (Rx CTCSS)
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.

Transmitting DCS (Tx DCS)
In this Menu, you activate DCS codes in tx mode. You can choose between normal R-DCS (DCS23N-DCS754N) and inverted R-DCS (DCS23-DCS754I).

Transmitting CTCSS (Tx CTCSS)
In this Menu, you can set a CTCSS tone in tx mode. You can choose: 50 groups of CTCSS tones. In channel mode, the CTCSS tones cannot be changed. Note: there are 50 groups of CTCSS (67.0 to 254.1 Hz).

Voice prompt function (Voice)
With this function, you activate a voice that informs you about any operation/ selection you are doing.

Frequency offset direction (Direction)
Using this function, you can set the direction of the frequency offset in rx and tx. You have the following options:

• Plus: Positive offset;
• Minus: Negative offset;
• None: None offset.

Note: you should set different frequency deviations according to the repeaters selected. This function is not enabled in channel mode.

Frequency offset (Offset)
In this MENU you can set the deviation between tx and rx. The frequency offset of this radio is 00.000-99.999MHz.

Channel Store
When the radio is in frequency working mode, DCS standby mode, inputs the desired frequency or parameters directly. NOTES: If you want to set CTCSS tones, DCS codes or the frequency offset, you have to do it before storing the channel. The channels already stored are displayed as CH-XXX (“CH” and -channel number), and other channels only display channel numbers.

Channel Delete (Delete)
In this menu, you can delete a channel on the radio.

Alarm Mode (Alarm Mode)

This function can set the tone alarm/alarm state/alarm time of the radio. The following three (3) options can be selected to start the alarm tone:

• Keep pressing the FM/AMS key for 3 seconds;
• Site: the speaker emits an alarm tone and the radio transmits it;
• Code: the speaker emits an alarm tone and the radio transmits it followed by an ANI-ID code.
• The speaker can emit an alarm tone and no radio transmission is OFF.

Scan of frequencies with CTCSS (SEEK CTC)
The function allows scanning the frequencies with CTCSS code enabled. NOTES: The function cannot be activated when the radio is set in Channel mode. The Scan will start only when the receiving band detects a signal.

Scan of frequencies with DCS (SEEK DCS)
This function allows scanning the frequencies with DCS code enabled. NOTES: The function cannot be activated when the radio is set in Channel mode. The Scan will start only when the receiving band detects a signal.

Squelch tail elimination (TALLY)
This function is used to eliminate squelch tail noise between handhelds that are communicating directly (no repeater). Repetition of a 55 Hz or 134.2 Hz tone burst mutes the audio long enough to prevent hearing any squelch tail noise.

Roger beep (ROGER)
When the PTT is released, the radio will beep to confirm to other users that you have finished your transmission and that they can start talking.

1750Hz Repeater Tone (R-TONE)
With this function, you can select 1000Hz, 1450Hz, 1750Hz, and 2100kHz repeater tones. To send out a repeater tone: You hold down the [PTT] + [SK1] key. If you have the keypad lock enabled on your radio, you can still send a 1750Hz tone the regular way without having to unlock your keypad.
