Important note:  The following information allows the user to program receive and transmit frequencies into the radio.   The user of this information assumes all legal 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 pair of needle nose pliers or a pair of tweezers.
3. A fully charged BP4 battery pack.

Getting the radio into the programming mode:

1. Use a small tip Philips head screwdriver to remove the two screws located on the bottom case of the radio.
2. Remove the two screws located on the back case of the radio near the top.
3. Carefully remove the front case and lay it aside being careful so that the black and white wire stay connected to the radio.
4. Install a charged battery into the radio.
5. Using a pair of tweezers or needle-nose pliers short both ends of the SMD capacitor labeled as C11 or C12, that is located on the front cover through a hole in the copper foil.
6. While shorting the capacitor, turn on the radio and continue to short the capacitor until a pop is heard in the speaker.  The pop should be heard in the speaker within 2 seconds of the radio being turned on.
7. Remove the short and carefully turn the front of the radio over to observe the LCD.  There should be a flashing “P” in the display.  If not, repeater steps 6 through 8 until the flashing “P” is in the display.
8. Once the flashing “P” is in the display, carefully reinstall the front cover (with the radio turned on) onto the rest of the radio, making sure that the pins on the two connectors are aligned correctly.
9. Momentarily select the P. PRI key, then momentarily select the 0 key.  The display should be blank.  

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. When the “P” is in the display enter the following digits, pressing each key momentarily:

154600  0000 154600

2. Momentarily press the ENT key.
3. Momentarily enter the channel number that you want the frequency data to be saved to. Channels 1 through 10 are a single keystroke. Channels 11 though 16 require a two digit entry – when one is selected it goes to the left display LED waiting approximately 3 to 4 seconds for a second digit. If no other digits are entered the data will go into channel 1. 

If the proper number of digits has been entered into the channel memory, the LED display will be blank.

To review the channel for proper frequency and tone data select the MAN or manual key and then the channel number you want to check.

What do the digits mean?

• The first six are the receive frequency.
• The next two (7^th and 8^th digits) tells the microprocessor that a CTCSS tone is required for receive at a frequency of 100.0Hz (Tone Code 12).
• The next two (9^th and 10^th digits) tells the microprocessor that a CTCSS tone is required for transmit at a frequency of 100.0Hz (Tone Code 12).
• The last six are the transmit frequency.   

Example 2: The transmit frequency is different from the receiver and a tone of 100Hz is required for receive and transmit.

When the “P” is in the display enter the following digits, pressing each key momentarily:

154600 1212 151625

2. Momentarily press the ENT key.

• The last six are the transmit frequency.  

Important note: Any tone code combination can be used in the receive and transmit tone code.

Example 3:  Receive only  - the transmit frequency is disabled to prevent accidental keying of the microphone on a frequency not allocated to the user. 

When the “P” is in the display enter the following digits, pressing each key momentarily:

Your local weather frequency can be programmed into the WSH-1, NSP516, or RSP-165 if there is at least one channel that is not being used. The common frequencies are: 162.400, 162.425, 162.475, 162.500, 162.525, 162.550 MHz.

Example 4:  Weather channel at 162.550 is wanted on an open (not used) channel.

1. When the “P” is in the display enter the following digits, pressing each key momentarily:

162550  0000 000000

2. Momentarily press the ENT key.

Deleting a channel from memory:

Important note:  It is necessary to have all unused channels deleted from memory so that the radio operates at maximum performance.

While the display is blank:

1. Momentarily select the DEL or Delete key.
2. Momentarily select the ENT or Enter key.

3.      Enter the channel number to be deleted.

User Mode

1. Turn the radio off when you have completed all of the programming.

2.      Install and tighten the two bottom screws and two top back screws. 

3.      Turn the radio on.

User Programming

The programming jumper must be disconnected to allow for transmit to occur.
