Squelch Indicators (LED) – Lights when signal is received.2. Channel Display (2Line x 24 character) – Shows channel parameters.3. MAIN (Rotary+Switch) – Power ON/OFF and Main channel volume control.4. GUARD (Rotary) – Guard channel volume control.5. Squelch Defeat (Push button) – Press to open squelch (in analog modes of operation)6. MN/GD (Toggle Switch) – Selects active channel (Main or Guard) for transmit and edit functions.7. G1/G2 (Toggle Switch) – Selects active Guard memory G1 or G2 for transmit and edit functions.8. HI/LO (Toggle Switch) – Selects Transmit Power: High (10w) or Low (1w).9. Keypad (12 Keys) – Control radio functions, 3 command levels.
5 Radio Familiarization – Channel Display TDFM-136Transceiver OperationRadio Familiarization – Channel Display1. Main channel information is displayed on the top row of the display.2. Guard channel information is displayed on the bottom row of the display.3. The Main channel can have up to 230 memory positions (001 to 230), the current active memorynumber for the Main channel is shown in the first three characters of the line.4. The Guard channel can have two memories, GD1 and GD2, the currently active Guard memorynumber is shown in the first three lines of the bottom row.5. Memories for the Main channel can be scanned, when in use scan information is shown at the 4thcharacter position on the top row.6. The current command level is indicated on the bottom row at the 4th character position.
6 Radio Familiarization – Channel Display TDFM-136Transceiver OperationRadio Familiarization – Channel DisplayThe following parameters are common to both the Main and the Guard channels.7. Up to eight characters are available for a text description of the memory.8. One character position is used to indicate the operating mode:Analog modes: wide "w"(25kHz.), narrow "n" (12.5kHz.)Digital mode: project 25 digital "D" (12.5kHz.).9. Eight characters are used to indicate the frequency in use.10. One character indicates either Receive or Transmit as: "R" or "T".11. The final character indicates the current squelch mode:Analog modes: noise squelch "x", CTCSS tones "t", DCS codes "c"Digital modes: monitor "m", NAC only "n", and TalkGroup + NAC "g"
7 Radio Familiarization – Basic Operation TDFM-136Transceiver OperationRadio Familiarization – Basic OperationThe basic operation for transmit and receive is as follows:1. The Squelch LED's are on if a valid signal has been received.2. Upon keying the radio, the "R" character at the second from right position on the line, will change toa "T". The character will revert to a "R" upon releasing PTT.3. The "MAIN" and "GUARD” receive audio volumes are separately controlled.4. In analog modes the "SQUELCH" pushbutton opens the squelch, in digital it opens upon receivingany valid digital signal.5. The transmit power level can be set to 1W (low) or 10W (high).
8 Radio Familiarization – Select Channel and Memory TDFM-136Transceiver OperationRadio Familiarization – Select Channel and Memory1. The MAIN channel data is shown on the top line of the display, MAIN supports 230 memory positions(001 to 230). MAIN is selected for edit and transmit by placing the MN/GD switch in the MN position.2. When the MAIN channel is selected, a specific memory may be selected by pressing the "CHAN" keyand then directly entering the memory number ( ), or by using the forward or backward arrowkeys (6 & 4) to scroll through the programmed memories.3. The GUARD channel has two memories: GD1 and GD2. When the MN/GD switch is in the GD positionthen the GUARD memory used is determined by the position of the G1/G2 switch.
9 Programming the Radio – Command Architecture TDFM-136Transceiver OperationProgramming the Radio – Command ArchitectureCommand TypesThere are two types of commands: inherent and edit.Inherent commands need no further input from the user (example: display brightness commands)Edit comands need further input from the user and must end as follows:Accept the changes, save and exitAbandon the changes and exitCommand LevelsThe commands are organized into levels, there are three operator command levels (1-3), a Maintenancelevel (4), and a Supervisor level (5). Command levels are indicated at the 4th character on the bottom row.Command levels are navigated as follows:go up one levelgo down one levelCommand levels 2 and 3 are time limited, if a command is not selected within 5 seconds the unit returnsto command level 1 automatically. When a level 2 or level 3 command is completed, the timer is resetand the radio remains on that command level until a command is selected, ESC is selected or time out.
10 Programming the Radio – Command Architecture TDFM-136Transceiver OperationProgramming the Radio – Command ArchitectureCommand ScopeThe commands can be characterized as belonging in one of three categories:Operating commands are those which perform a direct function related to the use of the radio.Edit comands allow the user to Edit the RF channel parameters (frequency, mode etc).Configuration comands affect how the radio operates, including how other commands work.Command NomenclatureThe commands and command levels are abbreviated as follows:Command Levels are abbreviated as Ln, where 'n' is the level number from 1 to 5.example: L2 = command level 2Command Numbers are abbreviated as -n, where 'n' is the command number from 0 to 9.example: L2-1 = command level 2, command 1 (Edit all/new channel)Command DescriptionThe commands are described in detail in both the Technisonic documents:TDFM-136 Operators Manual, (TiL document #99RE266) and theTDFM-136 Installation and Operating Instructions, (TiL document #99RE255)These documents are available on-line at
11 Programming the Radio – Operating Commands TDFM-136Transceiver OperationProgramming the Radio – Operating CommandsOperating Command ListThe Operating Commands are distributed across Level 1, Level 2 and Level 3 as follows:Level 1L1-1 jump to selected channelL1-2 and L1-8 change display brightnessL1-4 and L1-6 scroll through programmed memories on MAIN channelL1-5 start/stop scanLevel 2L2-2 copy current GUARD channel data to current MAIN channel.L2-3 lock keypadL2-8 copy current MAIN channel data to current GUARD channel.Level 3L2-9 display current Squelch Parameters.
12 Programming the Radio – Edit Commands TDFM-136Transceiver OperationProgramming the Radio – Edit CommandsEdit Commands - Cursor and PromptsWhen any Edit begins, a cursor is placed in the appropriate data field on the display, and the non-activechannel becomes a prompt line.Example: for 'Edit Frequency' on the MAIN Channel, a cursor is placed at the second character in theFrequency field (1), and the Guard display row becomes a prompt line (2).When editing the Guard frequency, the situation is reversed, the cursor is placed on the GUARD row (1), and the MAIN row becomes the prompt line.
