HOW TO READOUT FIELD PROGRAMMABLE FREQUENCY & TONE CODES
In our example,
channel 3 of a UHF radio is programmed to operate on the “Brown Dot”
frequency of 464.500 MHz (Frequency code “04”) with 100.0 Hz tone (Tone code “12”).
1. Place the radio into Program / Readout Mode by following the instructions
in FIG-7 at left. A
“
P
” will appear on the LED display as you enter program
mode.
2. Release the Push-to-talk button after the beeping has stopped. The radio
will display a series of six characters for Radio Identification, with each
character separated by a hyphen. The 1st two characters indicate the
model number, the 3rd and 4th characters indicate the radio type, and
the 5th and 6th characters indicate the firmware revision.
In this example: Model:
27
Radio Type:
31
Firmware Revision: 04
NOTE:
Radio models with firmware revisions prior to 16.01 do not
display the Radio Identification sequence.
3. After the Radio Identification has been displayed the digit 1 will appear,
followed by a hyphen, and the radio will emit a triple beep indicating that
the radio is in program mode and channel 1 is selected.
4. Press the Channel Selector button to select the channel to be read out.
The channel number will appear briefly on the display as you step through
the channels. When you have settled on a channel a hyphen will appear
across the center of the display to indicate that it is ready for readout.
5. Press and release the On / Volume Up button. The radio will begin to
display a series of four digits; with each digit separated by a hyphen.
The 1st and 2nd digits indicate frequency code;
see Table 1 on page 14
.
The 3rd and 4th digits indicate the tone code;
see Table 2 on page 15
.
If a 5th digit is displayed, the channel has been programmed for DQC and
the last three digits indicate the DQC code;
see Table 3 on page 15
.
If more than 5 digits are displayed refer to page 19.
6. If the channel is PC-programmed for any frequency not listed in
Table 1
on page 14
,
an error tone will sound and an “E” will appear on the
display.
7. To readout another channel, repeat steps 4 through 6.
8. Turn the radio OFF and then ON again
—the radio is now ready to use.
1. Press & hold the
Volume Down / Off
button until the
“Radio Off” tones are
heard, then release.
2. Press & hold
the Push-to-
Talk button.
3. Press & release
the On / Volume
Up button
– the
radio will start
beeping.
4. Continue holding the
Push-to-Talk button
until the beeping stops,
then release it and
listen.
5. The radio will emit a
triple tone: It is now in
