TFM-30 Installation & Operating Instructions 

TiL 98RE244 Rev n/c Issue 9

2.2   OPERATING INSTRUCTIONS (See Figure 2-1) 

1.

 

Switch power on by turning the main volume clockwise. Depending how the radio is 
configured, either the last programmed or last displayed frequency will appear on 
the screen. The transceiver is now in normal operating mode. 

2.

 

Adjust the audio level by adjusting the main and guard volume knobs. 

3.

 

Pressing the squelch-defeat button will open both receivers to confirm they work. 

4.

 

Read the display. The top line will indicate which memory is selected followed by a 
"+" if the memory position is included in a scan list, an alphanumeric message, and 
the frequency of the main receiver. A small "n" before the frequency indicates 12.5 
kHz narrowband channel spacing is in effect on this memory position. In the receive 
mode, the frequency is followed by an "RT" if a RX CTCSS tone or RX DPL code is 
programmed, or an "RX" if no Receive tone/code is programmed. Similarly, in the 
transmit mode either a "TT" or "TX" is shown after the frequency. The bottom line 
indicates similar information about the guard receiver. 

5.

 

Only TX CTCSS tones or TX DPL codes may be programmed for the guard receiver. 
At the beginning of each line, an LED indicates open squelch. 

6.

 

Set the MN/GD switch to main or guard transmit frequency. 

7.

 

Set the G1/G2 switch to the desired guard channel. 

8.

 

Set the HI/LO switch to the desired RF output power. 

9.

 

Select the desired memory by using the M.UP and M.DN buttons, or the RCL button 
and a three digit number followed by ENTER. 

10.

 

To transmit DTMF tones, use the keyboard keys while holding the PTT button on 
the microphone. The keyboard returns to its normal function when the PTT is 
released. 

 
The display always shows the status of both receivers and the transmitter. The light at the 
left of the top and bottom line indicates which receiver is receiving. The display also 
indicates the memory channel in use and the guard channel in use. A "TX" (no TX 
tone/codes programmed) or "TT"(either TX tone or code programmed) on the right side of 
the display indicates whether the guard or main channel is active when transmitting. The 
transmit frequency is also shown. In the receive mode the display shows “RX” beside the 
receive frequency if no RX tone or DPL code is programmed and “RT” if a CTCSS tone or 
DPL code is programmed. 
 
When the transceiver is in either of the operating frequency or CTCSS tone/DPL code 
programming modes and you must respond to a call, click the microphone PTT once (the 
radio will not transmit during this click). This will cause the transceiver to revert back to the 
normal operating mode and communications with the caller can proceed in the usual 
fashion. 
 
The TFM-30 was designed for compatibility with an industry standard Antenna Tuner Unit 
through the 9-pin connector on the rear panel of the radio. The ATU is enabled during 
transmit.
