Important note:  The following information allows the user to program receive and transmit frequencies into the radio.   The user of this information assumes all consequences of transmitting on frequencies not allocated to them for their use, even if by accident.  Some radios may need proper realignment in order to perform on the programmed frequencies or in order to operate at best performance. A qualified technician using proper test equipment should perform any required realignment.

Frequency Information:

The frequency information to be programmed into the radio must be obtained by the user.  The frequencies given in the examples listed in the Programming instructions are not allocated frequencies.  

Programming Preparations:

Items required:

1. One small tip Philips head screwdriver.
2. One fully charged battery.

Getting the radio into the programming mode:

1. Disconnect the radio from its battery. 
2. Using the Philips head screwdriver remove the three screws located on the back case of the radio.
3. Turn the radio upside down so that you can observe the three nickel plated screws.  Remove only the one closest to the battery latch button.
4. Carefully open the radio on the PTT (Transmit) button side, hinging it on right or opposite side as there are two flex circuits on the right side that can be torn or damaged if you are not careful.
5. Open the radio enough to locate the programming switch on the board on the back half, near the top.  It is a mini slide switch.
6. Flip the switch in the opposite direction
7. Carefully reassemble the radio.
8. Install one screw the rear case and tighten it snuggly.  Do not over tighten the screw.
9. Turn the radio on. 
10. A small “P” should appear in the display indicating that the radio is now in the programming mode.

You will need to make a list of frequencies has been written in the sequence as listed below:

The tone chart below is a list of available tones that the radio is capable of receiving and transmitting.  Use the two-digit tone code to indicate the tone frequency that is needed for the channel:   Ex. – Desired tone frequency = 127.3Hz, use tone code 19.

When your list is complete you will have the information in proper sequence so that program entry errors will be minimized.

Programming steps:

Example 1:  The receive and transmit frequency are the same with no CTCSS tone.

1. Select the M/S or Manual/Scan key.  The display should be showing “P1”
2. When the “P1” is in the display enter the following digits, pressing each key momentarily:

54600 (wait for the beep) 00 (wait for the beep) 0000 (wait for the beep) 54600 (wait for the beep) 00 (wait for the beep) 0000 (wait for the beep)

3. Momentarily press the T/M key.
4. Momentarily enter the two-digit channel number that you want the frequency data to be saved to. (Ex.  – 01 is for channel one.)

What do the digits mean?

1. The “P1” indicates the radio is in the programming mode and the “1” is the first digit of the receive frequency.  Do not enter the 1 for the frequency.
2. The first five numbers are the remaining five digits of the receive frequency.  Enter only the remaining digits of the frequency after the “1”
3. The radio will beep after the last digit of the receive frequency has been selected, indicating it has proceeded to the next step.

4.      The two-digit receive tone code is then entered.  00 equals no tone.

5. The radio will beep after the last digit of the receive tone code has been selected, indicating it has proceeded to the next step.
6. The four-digit receive DTMF code is then entered.  0000 equals no DTMF decode.
7. The radio will beep after the last digit of the four-digit receive DTMF code has been selected, indicating it has proceeded to the next step.
8. The “P1” indicates the radio is in the programming mode and the “1” is the first digit of the transmit frequency.  Do not enter the 1 for the frequency.
9. The next five numbers are the remaining five digits of the transmit frequency.  Enter only the remaining digits of the frequency after the “1”
10. The radio will beep after the last digit of the transmit frequency has been selected, indicating it has proceeded to the next step.

11.  The two-digit transmit tone code is then entered.  00 equals no tone.

12. The radio will beep after the last digit of the receive tone code has been selected, indicating it has proceeded to the next step.
13. The four-digit receive DTMF code is then entered.  0000 equals no DTMF decode.
14. The radio will beep after the last digit of the four-digit receive DTMF code has been selected, indicating it has proceeded to the next step.
15. The T/M key is equal to the enter key.

To review the channel for proper frequency and tone data select the PRI key and then the two-digit channel number you want to check.

Example 2: The transmit frequency is different from the receiver and a tone of 100Hz is required for receive and transmit and a DTMF ANI code of 9875 is used on transmit and receive.
