MPV32D Basic Program Instructions

Programming mode - Locating the programming switch

1. Remove the battery.

2. Remove the three black screws on the back of the radio.

3. Remove only one chrome-plated screw from the bottom of the radio, the one which is closest to the battery release button.

4. Very carefully separate the front and rear halves just enough to locate the program switch. (Position the radio so that the keypad is up and the PTT switch is on the left, the radio will open on the left side. The right side will have a flex circuit attaching the front and rear portions.) The switch is located between the On/Off and channel selector switches on a small printed circuit board. Relocate it to the "Up" position to set the radio into programming mode.

5. Reassemble the radio installing only one back screw into the back of the radio. This will hold the radio together while you are programming the radio, and lessen the chance of tearing either of the two flex circuits.

6. Attach the charged battery or a power supply to the radio.

To Program Frequencies: Note: The following is a modified version of the MP-series Programming procedure.

1. Turn the radio on. A "P" should appear on the display. If not, recheck the programming switch.

2. Press the M/S button. A "P1" should be in the display. The 1 is the first digit of the receive frequency.

3. Enter all six digits of the desired receive frequency. {Ex: 154570 (for 154.570 MHz)}

4. Enter the three-digit tone code, for receive tone, see Table 1 for CTCSS tones (tone squelch) or Table 2 for DCS codes (digital squelch). {Ex: 012 (for 100 Hz)}

5. Press zero four times. {Ex: 0000 (for no four-digit DTMF decode)}

6. A "P1" should be in the display. (If you are programming a Receive only channel, such as a weather frequency, stop at the "P1" and press the ENT or Enter key, then a two digit channel number {Ex: 01 (for channel 1).} Start over at step 2 to program the next channel. If a transmit frequency is desired enter all six digits of the transmit frequency. {Ex: 154570 (for 154.570 MHz)}

7. Enter the three-digit tone code, identically as in step 4

8. Press zero four times. {Ex: 0000 (for no four-digit DTMF encode)}

9. Press the ENT or Enter key, then a two-digit channel number. {Ex: 01 (for channel 1)}

10. To program the next channel, start over at step 2.

To Review programming while in the program mode:

1. When the P is in the display press the PRI key.

2. Press the two-digit channel number. Each section of the program of that channel will be displayed for a brief period of time. The radio will display receive frequency, receive tone, receive DTMF decode, transmit frequency, transmit tone, then transmit DTMF encode.

To Delete a channel from memory:

1. Press the A/D key.

2. Press the two-digit channel number.

3. Press the ENT or Enter Key

Radio Configuration Data

Options:

The stock radio configuration is 030110.

	Options	Number to select:
		0	1	2	3	4	5	6	7	8	9
A.	RCC Mode	Disable	Enable
B.	Scan/RCC Delay	1/2	1	2	3	4	5	6	7	8	9
C.	Transmit Time-out-timer (seconds)	Disable	15	30	60
D.	Busy Channel Lock-out	Disable	Enable
E.	DTMF Encode is sent	First PTT	Every PTT
F.	Channel Select Lock	Disable	Enable

To change the configuration the radio must be in the program mode with the "P" in the display.

Enter the five digits, one number for each option must be selected, then press the ENT (Enter) key, and then press 00.

Rarely used functions:

1. Most systems or communications operations do not require the use of DTMF ANI.
A four-digit DTMF ANI decode and encode function can be programmed in each channel. Only a four-digit number can be sent upon PTT or received. When programmed for transmit, and the PTT button is depressed, the four-digit number is sent in approximately 350 milliseconds. The four-digit number can be used, in place of zeros, at steps 5 (for receive) and 8 (for transmit) in the aforementioned programming procedure. The Radio Configuration should be programmed to transmit on Every PTT. While in the Pag or Page mode the receiving radio will open up only when the correct DTMF signal is sent. The receiver automatically returns to the DTMF decode mode once the encoded signal goes away and the receiving radio squelches for more than 3 seconds. The keypad on the front of the radio is active to send DTMF any time the radio is in the transmit mode and any number on the front is depressed. The four-digit ANI does not effect the keypad. It will send one digit at a time and does not require any programming. If used in the decode mode, radio to radio, the Radio Configuration should be changed to Every PTT.

2. BCL or Busy-Channel-Lock-out is usually not used unless the radio is utilizing a repeater or base station that is equipped with a telephone interconnect, and has a few to several users on the same channel.

3. RCC mode = Radio Common Carrier - It is not available in most areas. Also called MTS for Manual Telephone System. It was owned and operated by AT&T, other companies, as the first type of mobile phone system. It was popular in the 1960s, 1970s and up to the mid 1980s.

Master Clear:

The MP-series radio is shipped with several channels programmed. The programmed transmit and receive frequencies are for test purposes only, and are intentionally offset to keep the user from utilizing these programmed channels for communicating. If the end-user is not utilizing all 32 channels it might be easier to erase the test programming from memory by performing a Master Clear.

1. This is done with the radio in the programming mode.

2. When the radio is Off, hold down the function key. The Function key is located on the left side of the radio, just above the PTT switch. Also hold down the * or star key.

3. Turn the radio on while holding down these keys.

4. Release the function key and wait for the P in the display.

5. Program the customer's required frequencies.

6. It might be necessary to reprogram the Radio Configuration Data as all of the options are set to 0 as a result of the Master Clear.

Programming is complete

1. When programming is complete remove the battery or power supply.

2. Remove any screws you have installed during the process of programming the radio.

3. Carefully open the radio and move the programming switch to the down position.

4. Carefully reassemble the radio and install all 4 of the removed screws.

5. The radio should be ready to use.

Troubleshooting common problems:

1. Blinking display
Using a voltmeter, measure the DC voltage on the two top contacts of the battery. The battery must have a minimum charge of 10.8 volts. If the battery voltage drops below 10.8vdc the radio will not function correctly in the user or programming modes. A fully charged battery should measure from a minimum of 12.4vdc to a maximum of 13.0vdc.

2. Blank Display - Note: The radio does not have an internal fuse.
First, put the radio in the programming mode and see if the display lights up.

If the display appears normal when in the programming mode, perform the Master Clear and reprogram the radio.
If the radio display does not light up in the programming mode check the following:

1. Check the contact for the positive lead of the battery terminal that is attached to the front case. When the front and rear cases are put together it should make good contact to the AF or the center board. Be sure that the board and the contact are clean. Ohm the contact from the bottom to the inside of the contact to check for an open. If the contact got hot, it may have melted the plastic around it to the point where the screw is no longer providing a short between the two contacts.
2. Check the flex circuit to the On / Off switch to be burnt, cracked or broken.
3. Check the flex circuit to the On / Off switch for bad solder connections at the switch or where it solders onto the AF or center board.
4. Check the On/Off switch to be open.

3. No Receive

A. Perform the Master Clear as described previously and reprogram the radio. If the radio was subjected to a voltage surge(such as dropping the radio into a rapid charger with the radio turned on), or low battery for a long period of time, or to a close lightning strike, or other high static discharge, it may lose part of the parity information. The Master Clear is the way of correcting this problem.
B. Check IF reference crystal to verify that it is oscillating.

4. The battery does hold a proper charge when used in the rapid charger (BCMP)

General Information:
All Ni-Cad batteries of any type or brand will lose its ability to hold a charge if it is left in a charger, charged incorrectly, or the battery is not used to the point just before equipment failure.

A. Make sure that the user is not turning the radio on while trying to charge the battery. The radio should be left off at least 4 hours before being used as a monitor. If it is used as a monitor over a period of hours, the radio should be turned off and removed from the charger for about two minutes, then dropped back in the charger for at least two hours before using it. For best results: Use two batteries instead one and cycle the batteries in regular usage out of the charger.

B. The radio should be used until the display starts to flash. Then turn the radio off and charge it in the rapid bay for at least 4 hours. The slow rate bay will charge the 700milliamp battery (BPMP7) in approximately 14 to 16 hours, or the 1000milliamp battery (BPMP1) in 20 to 22 hours. This procedure should be done 4 to 5 times and unless the battery has been charged incorrectly for a long period of time or the battery or charger is defective, it should correct the charge capacity of the battery. For best results: Purchase a battery analyzer/tri-analyzer to evaluate customers batteries.

C. If the user removes the radio from the charger while it is in the rapid charge mode or the AC is interrupted (black-out or brown-out), the charger will flash Red or Orange. If the radio is removed for approximately 2 to 4 minutes, the charger will turn the LED off and reset. The radio or battery can be dropped back into the charger and it will switch back into the rapid charge mode. The charger will not switch back to the rapid charge mode if the radio is left in the charger during the AC interruption, or put back into the charger before it resets. For best results for areas subjected to repeated AC brown-outs or black-outs: Have the customer purchase a non-interruptible AC power supply with battery back-up and plug their charger into it.
