Hello Peedi Krack,

There are two buttons on the front of the Motorola SP50.

MON - This key is a Monitor button. It temporarily disables the squelch control so you can hear any muted or weak signals being sent on the channel. This enables you to ensure the channel is clear before you transmit.

OPT - This button controls Optional functions that might be programmed into the radio, such as channel scan.

Additionally your radio might also have a DTMF keypad (similar to a telephone keypad) depending on which version of the SP50. If installed, the DTMF keypad would be used for signaling and controlling devices over the air.

Best Regards,

Go Ahead. Use Us.

Instruction manual for the radius sp50 Motorola

Before spending much time on this radio, most SP50's will not meet the FCC regulations of Narrowband. We have recycled well over 200 now. Find a dealer, or you could email us with more information (what you want it to do, talk to, etc). There are a few things you are allowed to do with them and we have all the parts.

Motorola HTN9014c

Here are a few thoughts concerning charging a HNN9018 or HNN9044 battery in a SP50 radio:

1) Check the date code on your battery. Rechargeable batteries have a life expectancy of 2-3 years. Motorola brand batteries have a 3-digit number date code. The first number is the year of manufacture, and the next two numbers are the week of the year. Example: 352 would be 2013 (or 2003) the 52nd week.

2) Try another radio/battery in the charger and see if you have the same results.

3) Try charging the battery outside the radio. It will set front to back in the charger. The battery has an arrow on the bottom of it showing you which way to put it in the charger. If the battery charges in the charger without being in the radio, then your radio has a problem with the charging circuitry.

4) Clean your battery contacts with a pencil eraser, both inside the radio and outside, as well as on the battery itself. This radio's outside contacts are easily covered by film from hand oil and it will prevent the battery from getting a good charge.

5) Test your radio with another known good battery. If your radio is not working with the original battery and it appears to have not charged, it could be a radio problem, not a battery problem.

6) Try your radio in a different charger and see if you get the same result.

By this point in troubleshooting you should be able to determine if it is the battery, radio or charger.

Best regards.

How do i program my radfius sp50

Take it to a Motorola 2-Way Radio Dealer. They will determine if the channels you want to use can be programmed into that older model radio.

The Radius SP50 is no longer supported by Motorola so software and programming cradle are no longer available.

First, make sure the battery is fully charged and red LED TX indicator is on steady as long as you are holding the PTT button. If the red LED blinks while you are transmitting, the battery is not charged, or is bad.
Otherwise here are some common problems with the SP50 that can cause that issue:
Bad PTT switch
Internal microphone is bad
Speaker/microphone is bad-if used
Jacks are bad
Transmitter power amplifier is bad
Antenna is bad

Contact a local dealer for proper diagnosis.

How can i tell if i have a UHF radio or VHF radio

You can use the model number to tell if you are VHF or UHF. You will still need to know the frequency(s) and PL code(s) your radios have to get radios to match.

VHF model number starts with P93.
UHF model number starts with P94.

The current replacement radio for the SP50 is the CP200. It is construction grade and was made to replace the SP50. There are other radios which will also match the SP50 including (but not limited to) the BPR40 and the new CP185.
