1.1.2 Channel Parameter Display
Figure 1-2 below shows the display of the unit, and identifies the individual parameters
shown for each of the main and guard channels.
Figure 1-2. The TDFM-136B display – unique parameters highlighted.
The parameters that are specific to one channel or are not channel related are identified in figure
1-2 above. Items 1 – 6 fall into this category, they are described as follows:
1. 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 memory
number 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 memory
number 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
4th character position on the top row.
6. On the bottom row, the 4th character position is used for different purposes: it will indicate the
current command level as well as showing the lock icon () if the keypad access has been
locked out.
7.
Figure 1-3 below shows the display of the unit, and identifies those parameters that are
common to both main and guard channels.
Figure 1-3. The TDFM-136B display - common channel parameters highlighted.

TDFM-136B Operating Instructions 08RE399
The common parameters are identified as items 7 through 11 and are as follows:
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", or DCS codes "c"
Digital modes: monitor "m", NAC only "n", TalkGroup + NAC "g"
1.2 Transceiver Basic Operation
For basic operation of the transceiver the user has the yolk mounted PTT key and memory
up/down keys (if connected) in addition to the controls discussed previously. Basic
operation is discussed in this section.
1.2.1 Selecting the Active Channel – Main or Guard
When the user presses 'PTT', the unit will transmit with the parameters of the active channel and
memory, that the user has selected. The method of selecting MAIN or GUARD channel is
described below.
Figure 1-4. The active channel display and control points.
1. The MAIN channel data is shown on the top line of the display, MAIN supports 230
memory positions (001 to 230). The MAIN channel is made the active channel for
transmit and edit by the user placing the MN/GD switch in the MN position. For
selecting the active memory for the MAIN channel, see the following section.
2. When the MN/GD switch is in the GD position then the GUARD channel is active. The
GUARD channel has two fixed memories: GD1 and GD2, the GUARD memory used is
determined by the position of the G1/G2 switch.

08RE399 TDFM-136B Operating Instructions
1.2.2 Selecting a Main Channel Memory
For the MAIN channel there are 230 possible memory positions to choose from (001 to 230), the
method of selecting a memory for the MAIN channel is described below.
Figure 1-5. Control points for selecting an active memory for the MAIN channel.
There are several ways in which the user can control the active memory for the MAIN channel:
1. Press the 'CHAN' button (1), and then directly enter the three digit memory number.
2. Press and hold either the back arrow (4), or the forward arrow(6) button, and the unit will scroll
through the existing (already programmed) memories.
3. Press the 'ENTER' button (#), and the unit's Main channel will toggle between the current
memory and the designated 'home' memory. If no 'home' memory has been selected, then the
default is channel 1.
Note on scrolling:
•memory numbers that have not been created will be skipped.
•the scroll will wrap both up and down (. . . 230 ↔ 001. . . ).
Example:
The user has memories 001, 002, 004, 010, 024, 100 and 151 programmed into the transceiver.
The MAIN channel is selected, and the active memory is 004. No home memory has been
defined, so the default is 001.
If the back arrow is pressed and held, the MAIN display will scroll to memory 002, then to 001, and
then to 151, the sequence will continue until the user releases the key.
For the Main channel, if the user presses the “ENTER” button, then the MAIN channel will jump to
memory “001”, if the Main memory was something other than “001”, then pressing “ENTER” again
will return to that memory.

1.3 About Commands
The transceiver supports commands to provide more advanced control and configuration
features. A command is simply a key press, or series of key presses, that cause the unit to
perform a function. This section provides an overview of the command architecture.
1.3.1 Command Levels
In order to accommodate all the commands required to provide the necessary operation,
commands have been divided up into levels (abbreviated as 'L1', 'L2' etc). This results in the most
common commands needing the fewest key presses to access.
There are five command levels in all, three of which are available to the operator (Operator
Commands). For each command level up to 10 commands are available: 1-9, and '#'. Note: for
command level 1 (L1) only, the ESC (*) button has an associated function as you cannot go a level
down. The zero (0), and the ESC (*) key are reserved to move between the command levels as
follows:
step up through command levels
step down through command levels
When stepping through command levels, the level is shown as a subscript digit in the 4th character
position on the lower line of the display, see figure. Note that this display position is left blank for
the default level (L1).
Figure 1-6. The Screen showing 'Level 3” in the Command Level Display Position
The Operator Command levels 2 and 3 (L2 & L3) are 'time limited', if the user gets into one of
these command levels and does not enter a command within 5 seconds, the unit automatically
returns to command level 1.
Note that after exiting a L2 or L3 command, the timer is reset to 5 seconds, so if you want to return
to level 1 immediately, you have to press level down key ('ESC' or '*'). This allows you to perform
another command on that level without having to start over from level 1.
In addition to the three command levels available to the operator, the unit can be put into a mode
that allows access to maintenance and supervisor commands. These restricted command levels
(L4 & L5) are to allow authorized personnel to set operating policy for the radio through use of
'Permissions', and perform other maintenance and configuration functions; these are explained
later in the manual.
The restricted command levels (L4 and L5) should NEVER be enabled in flight. Incorrect
use could render the unit non-functional! These levels exist for configuration and
maintenance use only.

1.3.2 Command Types
There are two basic types of commands: inherent, and interactive:
Inherent commands
These are simple 'one-touch' commands, they do not need any further input from the user.
Example: the display brightness control commands (up/down arrows, keys 2 & 8)
Interactive commands
These commands require further input from the user, and they must end as follows:
accept the entry and exit
abandon the entry and exit
Example: the 'Frequency' command requires that the user enter a frequency, before exiting.
1.3.3 Command Groups
The commands can be characterized as belonging to one of three groups:
Operating commands are those which perform a function directly related to the use of the radio.
Edit commands allow the user to Edit the RF channel parameters (frequency, mode etc).
Configuration commands affect how the radio operates, including how other commands work.
1.3.4 Command Reference
Throughout the manual the commands will be referred to by level and number to make it clear what
command is being referenced. The short form used is as follows:
Level - abbreviated as 'L' followed by a number, a dash separator, and a command number.
Examples:
The 'edit frequency' command is: level one, command number 7. So the short form is: L1-7. Since
under normal circumstances the transceiver is in level 1, to access the command simply press '7'.
Level two, command number 3 is shown as: L2-3. To get to this command you must first go to
level 2 (by pressing the '0' key), then enter the command key, '3'.

This section describes operating the transceiver including using the command functions to
perform common tasks. This section provides more advanced information about
operating the transceiver, starting with the basics and moving through the more advanced
features.
2.1 Channel Operating Parameters
As described in the previous section the transceiver supports two (2) channels: Main and
Guard. Each of these channels operates using the parameters of the currently selected
memory for that channel.
The Main channel operates using the parameters of the currently active main memory, and
there can be up to 230 memories available to the Main channel. Main memory number 001
must always exist, and is the default Main memory when the unit is shipped.
Similarly the Guard channel operates using the parameters of the currently active Guard
memory. The difference is that the Guard channel supports only two memories: GD1 and
GD2, these may be selected via the front panel G1/G2 switch, both of these memories
must exist and are programmed from the factory.
The parameters for any factory programmed memory may be changed by the user.
2.1.1 Memory Parameters
Each memory has a variety of parameters that may be edited by the user including:
•frequency – 8 characters
•operating mode – 1 character
•squelch mode and squelch mode value – 1 character displayed
•text description – up to 8 characters
•scan list – 1 character
The ability to edit some of these may be restricted under certain operating conditions.
Example: while scan is available for any Main channel memory, the user may not set scan
parameters for either Guard channel, or for 'shadow' channels on the Main channel.
2.2 Editing Channel Operating Parameters
There are two ways to change the operating parameters for the memories used by either
the main or guard channel: edit from the transceiver front panel, or edit using the PC
programming software. This section will describe the first option; PC programming is
discussed in Appendix C.
From the front panel, the user can edit any of the parameters (listed above) for the active
channel using the individual parameter edit functions.
Technisonic Industries Ltd. 7
08RE399 TDFM-136B Operating Instructions
In addition to editing the memory parameters individually, the user can create new
memories (for the main channel only) or edit all the parameters of an existing memory (for
Main or Guard channels).
All edit commands are interactive commands (they expect input from the user), as such, the
line on the display that does not have the parameter to be edited, becomes a prompt line to
guide the user as to the valid keys for that edit.
Example: The edit frequency command, figure 2-1 shows the edit frequency screen if the
active memory is 001 on Main. Note that a cursor flashes on the second character in the
frequency field , on the Main display (top row) and that the Guard Display (bottom row)
has been changed to a prompt line . This prompt provides the user with information such
as what command is running, and what keys are valid.
Figure 2-1. The user screen to edit the Main frequency
When the Guard Channel is active, the situation is reversed: the cursor is placed on the
second digit in the frequency field on the Guard line, and the top line becomes the
prompt line.
Figure 2-2. The user screen to edit the Guard frequency
Calling Key.
Some editors simply allow the user to select a set value from a list; in these cases, the key
used to 'call' the editor will also step up through the available choices. This allows the user
to make a selection without having to further navigate the keypad.
Simplex and duplex parameters.
Some of the transceiver parameters are simplex only: they are the same for both transmit
and receive operation. Other parameters are duplex: these may be (but do not have to be)
different for transmit than they are for receive.
Accept and Continue / Accept and Exit
For many edit functions (example Operating Mode), once the user has selected a value,
pressing the key will accept the entry and exit the editor. However, some edit functions
require that the user accept a value before advancing (example Squelch Mode), in these
cases pressing the key will advance to the next point in the editor.
Abandon Edit
In all cases, the key will abandon the edit with no changes made.

2.2.1 The Frequency Parameter
The TDFM-136 supports frequencies in the range 136.0000, to 174.0000 MHz. Frequencies in the
analog wide band (25 kHz. channel spacing), the analog narrow band (12.5 kHz. Channel
spacing), and the P25 band (Phase 1 – 12.5 kHz. channel spacing) can be entered at any 2.5 kHz
step. In addition, frequencies can be entered on the frequencies proposed for P25 Phase 2. Note
that this does not mean that the transceiver operates in this mode (6.25 kHz. channel spacing), just
that the transceiver can be tuned to those frequencies; the channel spacing will still be either 25
kHz. or 12.5 kHz. See appendix D for the 6.25 kHz frequencies supported.
Frequency is a simplex/duplex parameter, that is, the unit can transmit and receive on the same
frequency or it may be configured so that the transmit frequency and receive frequency are
different.
Editing Frequencies
The edit frequency command is easily accessible, it is command L1-7. To access this command,
simply press '7', on the front panel keypad. Notice that the key is also marked “FREQ”.
This command allows the user to edit the operating frequency of the selected channel & memory.
The frequency will be edited in duplex mode: first Receive, then Transmit. Upon start, the cursor
appears at the second character in the Frequency field of the channel to be edited. The edit screen
appears as follows:
Figure 2-3. The user screen to edit the Main frequency for receive
The user may now enter the desired operating frequency as follows:
to decimal mode: enter number, cursor automatically advances
accept the entry and continue
abandon the entry and exit
The editor will not accept a value outside the limits of 136.0000 MHz. to 174.0000 MHz. In addition
frequency supports 2.5 kHz increments, and valid 6.25 kHz channel spacing frequencies in all
Operating modes. See appendix N for valid 6.25 kHz frequencies.
Once the receive parameter is entered, the 2nd last character in the display will switch from “R” to
“T”, the user can now enter the transmit value. Note that the receive value is automatically entered,
so to get simplex operation, simply accept this entry.

2.2.2 Operating Modes
The operating mode is defined as the RF channel spacing and modulation type used for the
selected channel/memory on the transceiver.
The unit supports three operating modes: Analog wide, analog narrow, and P25 digital. In the
analog wide mode, the radio is operating on 25kHz. channel spacing, on both analog narrow, and
in P25 digital mode, the radio operates with 12.5kHz. channel spacing. In analog modes the
transceiver operates using standard frequency modulation, in the P25 mode the unit uses C4FM.
Table 2-1 shows the available Operating Modes, the bandwidth, and the indicating character used.
Table 2-1 Transceiver Operating Modes
Operating Mode Bandwidth Indicator
Analog Wide 25 kHz 'w'
Analog Narrow 12.5 kHz 'n'
P25 Digital 12.5 kHz 'D'
The user can easily switch between modes on any memory for any channel (ie any Main memory,
and both Guard1 and Guard2). Since the squelch modes are not common across analog and
digital operating modes, if you change between these modes, the Squelch Mode will be affected
(for more on this see 'Squelch Modes' below).
The operating mode is a simplex parameter.
Editing Operating Mode
The edit operating mode command is easily accessible, it is command L1-3. To access this
command, simply press '3', on the front panel keypad. Notice that the key is also marked “MODE”.
This command allows the user to edit the operating mode of the selected channel & memory. Since
operating mode is simplex only, the editor is very simple. Upon start, the cursor appears at the
operating mode character field of the channel to be edited. The edit screen appears as follows:
Figure 2-5. The user screen to edit the Main Operating Mode.
You may now edit the Operating Mode as follows:

TDFM-136B Operating Instructions 08RE399
2.2.3 Squelch Modes
Squelch mode refers to the method employed to defeat squelch and open the receiver. The
transceiver supports a variety of squelch modes for both analog and digital operation, these are
shown in table 2-2 below.
Table 2-2. Receive and Transmit Squelch Modes
Analog Digital
Rx Tx Rx Tx
Noise x CTCSS Tones t Monitor m TalkGroup + NAC g
CTCSS Tones t DCS Codes c NAC Only n ID Call i
DCS Code c Inhibit - TalkGroup + NAC g Inhibit -
Non-Selective Squelch
In analog operating modes (w & n), the Noise squelch is non-selective, that is: if a valid signal of
enough power is present, the squelch will be defeated and the signal received.
Note: Noise squelch is the only squelch parameter that is global, the value needs only to be set
once on any memory and it will apply to all memories on that channel.
For the P25 digital mode (D), the Monitor mode is non-selective: it a P25 digital signal of enough
power is present, the squelch will be defeated and the signal received. There is no level setting.
Note: this does not mean that encrypted signals will be received and decoded in these modes!
Selective Squelch
The other squelch modes are selective: the transmitting system must be operating in the same
squelch mode as the receiving system, and must provide the correct information within that mode.
Scope
Squelch modes are non-orthogonal, that is, they are not the same across differences in Operating
Mode or for receive and transmit operation.
Parameters in Memory
For each memory created there is a default value for each of the squelch modes: the memory
does have a CTCSS tone, a DCS code, a TalkGroup and a NAC assigned, it is just that these
parameters are not used unless the associated squelch mode is chosen.
Since each squelch parameter exists for each memory, and each has a default value, these default
values, like all user editable channel parameters, can be set. In addition, Squelch use may be
restricted according to: which Squelch Modes may be selected for any Operating Mode, which
Squelch Modes may be edited (ie change value), and – in the case of Tones and Codes – which
values are available to be selected. See the Maintenance Level (L4) for appropriate commands.
Description
For signals that are on frequency and not encrypted, the Squelch Modes work as follows:
In Analog Modes:
Noise Squelch, 'x' – analog receive only, non-selective. The receiver will open if there is
enough RF energy on frequency. This is the default analog squelch mode.
CTCSS Tone, 't' – analog receive and transmit, selective. The receiver will open if the signal
received also carries the correct tone. The tones may be the same or different for receive or
transmit on any memory.
DCS Code, 'c' - analog receive and transmit, selective. The receiver will open if the signal
received also carries the correct code. The codes may be the same or different for receive or
transmit on any memory.
Technisonic Industries Ltd. 11
08RE399 TDFM-136B Operating Instructions
In Digital Mode
Monitor Mode 'm' - digital receive only, non-selective. The receiver will open on any valid P25
signal. This is the default digital squelch mode.
Network Access Code (NAC) 'n' – digital receive only, selective. The receiver will open on
any P25 compliant digital signal, having the correct NAC.
Talkgroup + NAC 'g' – digital receive and transmit, selective. The receiver will open on any
P25 compliant digital signal, having the correct NAC, and the correct TalkGroup. For transmit it
indicates that the specified NAC and TalkGroup codes will be transmitted.
ID Call 'i' – digital transmit only, selective. The transmitted signal will carry the ID of a specific
transceiver. Only a radio with that ID programmed as it's Unit Identification (UID) will be able
to receive the signal. Note that the UID can be set via command L5-9.
In Both Analog and Digital Modes
Transmit Disabled '-' – valid for both analog and digital operating modes, transmit only. This
indicates that transmit is disabled for this memory. Pressing PTT will result in a display of
“Transit Disabled” on the screen.
Editing Squelch Modes
The edit squelch mode command is easily accessible, it is command L1-9. To access this
command, simply press '9', on the front panel keypad. Notice that the key is also marked “SQL”.
This command allows the user to edit the squelch mode of the selected channel & memory. Since
squelch mode is duplex, and the selective squelch options have values that can be edited as well,
this editor has more steps than most others. The general flow of the editor is as follows:
1. Select receive Squelch mode (dependent on operating mode).
2. If Squelch mode has a value then select the value(s)
3. If simplex then done, else repeat for transmit.
All Squelch mode edits start the same way, the cursor appears at the Squelch mode character field
of the channel to be edited. The edit screen appears as follows:
Figure 2-6. The screen to edit the Main Squelch Mode for receive.
You may now edit the Squelch Mode as follows:
step up/down through available squelch modes.
accept the entry and exit
abandon the entry and exit
Remember that the available squelch modes will be constrained by the operating mode as shown
in table 2-2 above.

Note that the cursor drops to the bottom row, ready to edit, for noise squelch, the editor operates
as follows:

abandon the entry and exit
If editing the receive value, when you press “ENTER” to continue, the editor returns to the first
screen, but the Transmit/Receive indicator character (second last character on the line) has
changed to a “T” to indicate that you are editing for transmit. This allows you to set 'duplex values
for the selective squelch (ie transmit may be different than receive). The screen to select a transmit
squelch mode appears as follows:
Figure 2-8. The screen to edit the Main Squelch Mode for transmit.
The edit keys are the same as for the first screen.
Note that for analog modes “Tx” indicates that no selective squelch will be used, there is no value
associated with the “x” choice for transmit.
For analog CTCSS Tone squelch the user would have to select 't' in the initial screen (in analog
modes only), if so then the editor to change the value would appear as follows:

2.2.4 ID Call Operation
As seen above, the transceiver can be configured, in digital mode, to use ID call as a selective
squelch method, in this mode the transmitting unit sets it's TalkGroup to zero (0), and transmits the
intended Unit ID number (decimal 0 to 9,999,999), upon seeing the '0' talkgroup, the receiver
ignores everything except the ID number.
Of course the receiver will have to be on the correct frequency and in digital mode.

The TDFM-136 has two distinct RF modules (Main and a dedicated Guard receiver). Unit ID's are
set to default ID's of 1 for Main and 2 for Guard. The Unit ID is a user set number, not a factory ID,
so if they are to be used, then they need to be set. The command to set the Unit ID is command
L5-9, the UID (Main or Guard) to be set is determined by front panel switch positions. The screen

abandon the entry and exit
The edit mode is decimal only seven digits 0000001 to 9999999.
2.3 Scan and Multi-Mode Operation
The transceiver supports two modes of operation where it is able to receive signals on
more than the displayed main and guard memories. These modes are: scan and multi-
mode operation.
2.3.1 Scan Operation
The radio supports a basic scan mode that operates on the Main channel only. The scan function
allows users to monitor up to 16 channels at a time. All memories must be a member of one, and
only one, scan list; each scan list can hold up to 16 memories. Each memory in a scan list can be
enabled for scan or disabled (see command L2-5).
To scan a particular list: the current Main channel memory must belong to that list, and must have
it's scan enabled. Under these conditions, when you press the scan button (5), the unit will scan.
Example: There are seven (7) memories assigned to scan list three, these are: 5, 6, 13, 15,
23, 34, and 51. Memories 6 and 15 have scan disabled, the rest have scan enabled.
If the user is on channel 6 or 15 and tries to start scan (command L1-5), there will be
an error message: “Error: Non-Scanned Chan” and nothing will happen.
If the user is on any other channel in scan list three, then the five scan-enabled
channels in list three will be scanned.
You can enable or disable scan for the displayed memory (for Main channel only) by using the
command L2-5.
You can affect the scan operational parameters by using command L3-5. This command allows
you to affect the following four (4) parameters:
•Revert Mode
•Reply Timer
•Monitor Timer
•Delay Timer
16 Technisonic Industries Ltd
"#+:;
:;%/
TDFM-136B Operating Instructions 08RE399
Revert Mode. The Revert Mode refers to whether the radio will, when keyed, transmit on
the currently selected memory channel, or on the last contacted memory channel. The radio will
only respond on the last contacted channel for a time determined by the Delay timer setting, once
the timer times-out, then the unit always transmits on the selected channel.
Default: last contacted
Reply Timer. The scan Reply time is the time that the radio will monitor a channel on which RF
was received, after all activity on the channel has ended (Rx or Tx). If there is further receive or
transmit activity on the channel, the timer will reset, and start again once the activity has ended.
When the timer times-out the unit will resume scan. If set to zero (0), the unit will resume scan
immediately upon the end of channel activity.
Range: 0-20s, Default: 3 seconds
Monitor Timer. This is the time that the radio will monitor a channel on which RF was received,
before resuming scanning. Once the timer expires, the unit will break and resume scan, if the value
is set to zero (0) then the unit will monitor the signal as long as it is received.
Range: 1-90s, Default: 10 seconds
Delay Timer. The Delay time is the time that the radio will remain monitoring a channel after
receiving on that channel has ended. If the timer is set to zero, (0), then the unit will resume
scanning immediately after receive activity ends. This is the timer that affects the Revert Mode
'Contacted'.
Range: 0-15s, Default: 5 seconds
2.3.2 Multi-Mode Operation
Multi-mode operation allows mixing of analog and digital operating modes on one frequency. In
effect, this mode allows one memory position to be set up as though it has multiple sets of
parameters associated with it. This manual will refer to this as 'shadow memory' operation: a
'primary' memory can have up to seven 'shadows' for a total of eight sets of operating parameters
(1 primary + 7 shadows).
The user invokes this mode by selecting an existing memory to be a 'primary' and assigning at
least one 'shadow' memory to it, the command to do this is L2-7. Each 'shadow' takes up one
memory position, just like a normal memory.
The shadows have certain restrictions:
•a shadow must have the same frequency as the primary
•a shadow cannot have scan enabled
•a shadow cannot transmit in digital ID call (i) mode
You can mix analog and digital Operating Modes, you can configure different shadows to have
different squelch parameters.
Shadow operation is much like scan in last contacted mode, once a signal has been received, the
user has a set amount of time to key the radio, the unit will transmit with the parameters of the
shadow that decoded the signal: in other words you will respond to the person who called you.
When mixing analog noise squelch with analog selective squelches, the noise squelch shadow will
delay decode for a short time to allow the selective squelch channels time to decode, if none of the
selective squelch channels decode a valid signal, then squelch is broken on the noise squelch
channel.
The radio will operate in Mixed Mode when the Main channel has any memory in the shadow
group selected (ie either Primary or any shadow). The only difference between selections is that if
the user keys the radio, other than to respond to a received transmission, then the radio will
transmit using the displayed parameters.

Figure 2-15. Identifying Graphic for Primary Channel with Shadows
Shadow memories are identified with a small diamond in the 4th character position:
Figure 2-16. Identifying Graphic for Shadow Channel
2.4 Controlling User Access
Whether to restrict operation to correct modes, or to help avoid mis-configuration in the
field, it may be advantageous to control user access to certain features. The transceiver
supports controlling access to features in different ways, these include:
1. Controlling access to command levels.
2. Controlling access to individual commands via command permissions.
3. Controlling access to squelch modes.
4. Controlling editing of specific memories.
5. Controlling display of frequency information.
2.4.1 Control Access to Command Levels
The most basic access control is provided by the built in restriction of access to Maintenance and
Supervisor level commands (L4 and L5 respectively). Maintaining this access security is crucial for
any subsequent access control, as those methods are all accessed via commands on the L4 and
L5 programming levels. Access to these command levels is gained on one of two ways:
Access via Jumper requires that a hardware jumper (shunt) be placed across two pins inside the
transceiver. Obviously the transceiver must be opened on a bench to use this method. See
appendix A for side panel removal instructions and jumper placement.
Access via Jumper and Passwords is the default condition. When configured like this the
transceiver does not need to be opened to access the restricted command levels. There are two
passwords: one for level 4 (Maintenance), and one for level 5 (supervisor).
Passwords are eight characters long and have the full range of characters available for text edit
(see L2-6 for character list reference).
When attempting to enter the Maintenance Level (L4) you will be prompted for a password, upon
correct entry of the L4 password, you will be granted access to that level
When attempting to enter the Supervisor Level (L5) you will be prompted for a password, upon
correct entry of the L5 password, you will be granted access to that level.
If the Supervisor password is entered when attempting to access the Maintenance level, then
access to both Maintenance and Supervisor Levels is granted.

The screen to enter a password upon trying to access L4 or L5 looks like:
Figure 2-17. The screen to enter a password for restricted level access.
Passwords can use any character supported by the standard TDFM-136B text editor, as such the
editing keys are the same:
Step through the available edit groups (A-Z, a-z, 0-9, + extra characters – see table 4.3)
step up/down through the characters in each edit group
move backward/forward through the available characters
accept the entry and exit
abandon the entry and exit
Setting Passwords is done via command L5-7, the command is fixed to edit the Maintenance
password followed by the Supervisor password. Passwords must be eight characters.
Figure 2-18. The screen to set the Maintenance password.
The editor works the same as for entering the password, except that if you are editing the
Maintenance password 'ESC' and 'ENTER' work as follows:
accept the entry and continue to Supervisor
abandon the entry and continue to Supervisor
When entering the Supervisor password screen 'ESC' and 'ENTER' work as in other editors:
accept the entry and exit
abandon the entry and exit
2.4.2 Set Command Permissions
Command permissions allow those responsible for setting policy to select which commands in the
command set will be accessible in the Operator Levels (levels 1, 2, and 3). All the commands in
those three levels are affected EXCEPT: ‘PROG’ (0) and ‘ESC’ (*).
Table 2-3 below indicates all the available user commands, and shows the permission mode as
follows:
●indicates a command that has a distinct permission
●indicates a command is available in Guard, but permission is controlled by Main.
X indicates a command that is NOT available for the channel.

The default configuration from the factory has all commands enabled, except L2-2 and L2-8.
Permissions are controlled via three screens that allow you to visually enable or disable each
command for Main and Guard on a level by level basis.
The Set Permissions screen shows the level being affected (L1, L2, or L3), followed by the
command number, and an optional 'g' indicating Guard channel operation for that command (if
applicable). The character directly under each number (or 'g') indicates whether or not the
command may be accessed. If the command is to be accessible (or enabled), then the character is
a is solid round dot, if the command is to be restricted, (or disabled), then the character is an empty
dot or donut. The ‘Set Permissions’ for command level 1 screen appears below:
Figure 2-19. The Screen to Edit the Level 1 Permissions
The user may edit the permissions as follows:
Toggle permission ( @ = enabled, A = disabled
step up/down through Operator Levels
move backward/forward through the available commands
accept the entry and exit
abandon the entry and exit
Note that the cursor will automatically jump to the next valid column, the cursor will wrap. The ‘g’
indicates a separate Guard option; for the commands that support this, the Main and Guard can be
enabled/disabled separately. In addition, some of the commands are either channel agnostic, or
specific to the Main channel only and can thus be invoked for Main even when the radio front panel
switches are in the Guard position.
For example: with the switches in the Guard position the user can still scroll through the Main
memories using the and keys. These types of commands are available in the Guard
mode, but the permissions are determined by the Main permission.

2.4.3 Control Access to Squelch Modes
The squelch modes are among the more complicated editing and configuring options; the system
supports an access control scheme that allows you to enable access only to modes that your
organization or specific mission needs.
Command L4-9 is used to restrict user access to squelch modes, editing, and select options, this
can be used to simplify operation and reduces the potential to mis-configure the system. The
access restrictions operate according to the following table:

accept the entry and exit
abandon the entry and exit
Note you may only restrict editing of a selected value in analog modes.
2.4.4 Control Editing of Memories
In some cases it may be advantageous to set up a memory, and then ensure that the configuration
of that memory cannot be changed by the user. Command 4-4 provides this function. The
currently selected channel memory - as determined by the front panel switch positions -may be
enabled or disabled for editing. The command screen appears as follows:

Note, once a channel has been disabled for editing, any attempt to call a function that would edit a
parameter of the channel would display an error as shown below:
Figure 2-22. The error screen on trying to edit a disabled memory.
Remember that all the channel functions work as normal, they just cannot be changed.
2.4.5 Control Display of Frequency Information
Some agencies may want to restrict access to displayed frequency information for the memories
on Main and/or Guard channels. Command 4-7 provides this function. The currently selected
channel memory - as determined by the front panel switch positions -may be enabled or disabled
for editing. The command screen appears as follows:
Figure 2-23. The Frequency Display Enable/Disable screen.
The user may change the frequency display for the selected memory as follows:

2.5 Encrypted Operation
The TDFM-136 supports encrypted operation using both DES OFB and AES encryption
keys for P25 communications. The sequence to use encryption is as follows:
1. Load keys using a KVL keyloader.
2. Assign a KeyTag (name) to a key, defined by its SLN.
3. Assign a key, via the KeyTag to a memory.
4. Enable or disable use of encryption in radio operation.
2.5.1 Loading Encryption Keys
In order to use the encryption feature on the transceiver, you must have encryption keys loaded
into the unit. The keys must be loaded into the unit using a KVL-3000+ keyloader. Of course the
keys must have been created in the KVL first. Operating instructions for the KVL are beyond the
scope of this document, see manufacturer documentation.
Note: The keyloader (KVL) must be connected to the transceiver with the correct cable: ensure
you only use a cable designed for use with the TDFM-136B.
Once you have a KVL with the correct keys loaded, follow this procedure to load and use them in
the transceiver:
1. Connect the KVL to the TDFM-136 via the correct cable.
2. Load the keys following the KVL procedure. The keys will load to the Main or Guard
module as determined by the front panel switches.
3. Once you have loaded one module, you must load the same keys in the same order into
the other module. This is because the Guard operation is split across the two hardware
modules.
2.5.2 Assign KeyTag to Encryption Keys
Once the keys have been loaded, you need to assign a name (referred to here as a KeyTag) to the
key so that they can be manipulated later. Initially, the key will be identified by it's SLN (sometimes
called CKR).
Command L4-8 allows you to set the KeyTag for any of the keys loaded into the radio following this
sequence:
1. Select the key, by SLN, to assign a KeyTag to.
2. Enter the KeyTag
3. Repeat for other SLN's if desired.
Select Key by SLN. The first screen, shown below, allows you to step through the available
keys (by SLN), and shows the encryption algorithm for that key.

You can now select a key via it's SLN to assign a KeyTag to, using the following keys:
move backward/forward through the loaded keys, by SLN
accept the entry and continue
abandon the entry and exit
Create KeyTag for Selected Key. The next screen allows you to create a KeyTag for the
key selected. The system defaults to naming the KeyTags “Key Tag 01”, through “Key Tag 16”, this
screen allows you to change these names to suit your needs.
The KeyTag is 10 characters and is limited to: Upper & lower case alphabetic, the digits 0-9, a
space, and {! “ # $ % & ' ( ) * + , - . /} not including the brace brackets.
The screen to edit the KeyTags looks like this:
Figure 2- 26 . The screen to edit the KeyTag.
The keys for the KeyTag text editor operate as follows:
Step through the available edit groups (A-Z, a-z, 0-9, + extra characters – see table n.n)
step up/down through the characters in each edit group
move backward/forward through the available characters
accept the entry and continue
abandon the entry and continue
Repeat or Exit. The final screen allows you to decide to loop back and repeat the process for
another key or to exit the editor entirely:
Figure 2- 27 . The screen to assign another KeyTag or exit.
The edit keys are:
accept the entry and continue
abandon the entry and exit
2.5.3 Assign Key by KeyTag to Memory
Once the keys have been loaded, and they have been given KeyTags, the user may now assign a
key, using KeyTags, to a memory, provided that the memory is in P25 digital mode.
Command L3-2 allows you to assign a key to a memory in the transceiver following this sequence:
1. Select the memory to assign a Key to.
2. Assign the key via the KeyTag
3. Determine decrypt rules (assigned key or any key)
4. Repeat for other memories if desired.

2.5.4 Enable/Disable Encrypted Operation
Now that keys have been loaded and assigned to various memories in the transceiver, you can
enable or disable encrypted operation.
On a Digital memory, that has a key assigned to it, the Encryption may be enabled or disabled
using the command L2-9. The command is inherent, there is no edit, either the encryption can be
enabled or it cannot. If you try to enable encryption on an anlog memory (unsupported), you will
see something like:
Figure 2- 32 . The analog memory encryption error screen
On a Digital memory, that does not have a key assigned to it, you will see something like:
Figure 2-33. The error screen for no encryption key assigned
When correctly configured (a key assigned to a Digital memory), you will see something like:

If editing a Guard memory (G1 or G2) then proceed to L2-1.3 as the memory for the Guard channel
is determined by front panel switches only, and scan is not supported for Guard.
L2-1.1. Entering a Memory Number (refer to L1-1 for details)
When the Create/Edit All command is selected, the first step is to enter the number of the memory
position that you wish to Create or Edit, for Main Channel memories, the valid range is (001 to
230).
Once a number has been entered, the system checks to see if the memory location has already
been programmed, if so, then the existing data will be loaded; if the location has NOT been
previously programmed then the default template data will be loaded. In each case the user can
edit the channel parameters in the same way as shown in the following steps.
L2-1.2. Enter a Scan List & Enabling/Disabling Scan (refer to L2-5 for details)
After entering a MEMORY number the cursor will move to the fourth (4th) position on the top line,
the default scan list is shown in subscript. If there is a bar over top of the character, this indicates
that scan is disabled for this memory, if there is no bar, then scan has been enabled. The 'PROG'
key (key 0 ) toggles the scan enabled/disabled state.
L2-1.3. Enter a Text Description (refer to L2-6 for details)
After SCAN, the cursor advances to the first position in the eight (8) character text description field,
the user may now edit the existing text as desired. The editor allows you to select all upper and
lower (A-Z, a-z) case alphabetic characters, the numbers from zero to nine (0-9), and a selection of
extra characters including the space.
L2-1.4. Enter an Operating Mode (refer to L1-3 for details)
After TEXT, the cursor advances on the one (1) character Operating Mode (Mode) field, this single
character represents the operation of the radio: analog wide, analog narrow, or digital.
Technisonic Industries Ltd. 35
08RE399 TDFM-136B Operating Instructions
L2-1.5. Enter a Frequency (refer to L1-7 for details)
After MODE, the cursor advances to the frequency parameter field, this is a seven (7) digit decimal
parameter, though the first digit is always one so the user cannot edit that digit. The frequency
parameter may be edited to any number between 136.0000 and 174.0000 in 2.5 kHz. steps. (ie
150.0025 is valid, 150.0046 is not).
This is a duplex parameter, that is, the user has a chance to edit both the receive value followed by
the transmit value. Once the receive value has been accepted, pressing 'ENTER' again will accept
the same value for transmit. If you wish to have a different value for transmit, then enter it now,
otherwise accept the value for simplex.
L2-1.6. Enter the Squelch Parameters (refer to L1-9 for details)
After FREQUENCY, the cursor advances to the Squelch Mode field. A single character field shows
the Squelch Mode selected. This is a duplex parameter so a different mode can be chosen for
transmit than was chosen for receive. Note that the modes available will be restricted by the
Operating Mode (ie the modes available are different for analog and digital operation).
Once the user is finished and selects ‘ENTER’ then the newly edited channel parameters are
selected and displayed for the appropriate channel. This may take a moment as the information is
programmed into the appropriate RF module at this time as well.
3.2.2 Copy Guard to Main
Level 2 Key Scope: Main only
Copy the currently displayed Guard information UP to the Main channel. This is irreversible, so be
sure you wish to do this. As a safety precaution this command is disabled from the factory. (see

The user may now edit those data fields that are valid for a shadow channel. These are:
•Text Description
•Operating Mode
•Squelch Mode and associated value
The editor functions and keys are the same as for any of the independent editor operation, the
difference, as with Create New / Program All (L2-1), is that the ENTER key will advance to the
next editor until all valid fields have been entered, then the ENTER key accepts and exits.
Note that there are some parameters that cannot be edited:
•Frequency is fixed to that of the Primary channel
•Shadow channels cannot be scanned.
•Shadow channels cannot use the Digital Squelch Mode IDcall (i).

3.4 Maintenance Commands (Level 4)
The Maintenance Command Level is a restricted command level; that is, access to these
commands is restricted to authorized personnel. This restriction is enforced by requiring
either a password or requiring that a shunt be placed on a specific set of jumper pins on the
MCU board of the radio.
The Maintenance Commands available allow authorized personnel to set policy for the
radio use, by granting or restricting access to system commands and features.
This command level does not preserve the Normal Operating display characteristics, that
is: the Main and Guard displays are replaced by suitable command prompt information.
3.4.1 Set Default Record
Level 4 Key Scope: Main and Guard
This command allows the user to set up the default record that is used when a user selects Create
New/ Edit All (L2-1). This allows you to determine what parameters you wish to have as system
defaults. Some of the parameters are subject to restrictions set out in L4-9.
NOTE: If these values are set first, and the restrictions are set after, it is possible for the
user to end up using a parameter that you wish to restrict!
The Default Record editor works just like the Create New/ Edit All command (L2-1) except that it
takes you through all the possible squelch combinations so that each selection can be edited.

08RE399 TDFM-136B Operating Instructions
The TDFM-136B supports loading memory data from a PC using TDP-136 software. Be
sure not to use 'MultiTDP' it does not work with this radio.
For full information see the “TDP-136 PC Software Installation & Operating Instructions”,
TiL #00RE277.
In brief, you will need:
A PC running Microsoft Windows (2000, NT, XP, Vista, or Win7), with the correct TDP
installed.
A suitable connecting cable (TiL #003469-1) or a TiL Radio Test Jig (04T139) and serial
cable (9 pin).
24-30Volt power supply @ 3A.
With the unit powered up and correctly connected to a PC, put the radio into PC
Communications Mode (use command L3-8). Once done you will see:
Start the TDP, you will see something like:

TDFM-136B Operating Instructions 08RE399
Once the transceiver is in PC communications mode, and is correctly attached to a PC
running the TDP software, then the control of all functions is via the software running on the
PC.
You can get the contents of the transceiver using the “Upload (from Radio)” button.
You can edit a record by clicking on the appropriate line in the memory summary box and
then changing the values in the “Basic Information”, “Rx Information”, and “Tx Information”
blocks at the top of the screen. Note that the “Tx” function is un-editable unless you have
the duplex “Dx” button selected. Press 'Save Record” when done.
Create a new record by selecting a Memory number using the “Channel” scroll widget, then
fill out the appropriate information for Basic, Rx and Tx. Again, press “Save Record” when
done.
Once you have modified a file, or created a new one, press “Download (to Radio)”, and the
records will be transferred to the transceiver.
