Check the conductors where the battery passes energy to the radio, ake sure the tabs are clean and bent out to make good contact. The electrical draw in the battery is much lower than just turning on the unit opposed to pushing the PTT button. Also, use a volt meter and make sure the batteries are not weak and dropping voltage when you use the PTT button. These batteries do need replaed from time to time, especially if you never allow them to run all the way down to dead. This should be done (running batteries until they're dead) once every 1-2 months on any re-chargeable battery, it will greatly extend the battery life. This is true of all re-chargeable batteries.

Talkabout MH230R does not Receive or Transmit on channel, can just Transmit (only clicks when Recieve) when programmed 2 channels higher (i.e. all radios on 5-3, one is on 7-3)


Strange. Could it be any of the radios are from different countries? The channels are not worldwide. For instance, Canadian radios are on different frequencies than USA radios. They look identical.

Motorola Talkabout MR will not transmit


From reading through your settings, they appear to be identical. Except, I am not certain what Vox 2 is, or B5 0. If the number 2 beside VOX is a setting, you should set it to off or zero. Otherwise, they appear like they should work. (VOX = voice activation, and when enabled will cause a radio to transmit when it hears a sound, voice, etc.)
If you are using an audio device such as an earpiece or headset, be certain you are plugging it in with the radio turned OFF.
Lack of transmit can also be a sign of a bad battery or bad battery connection. You might try swapping the batteries and see if the problem moves to the other radio.
If these are less than one year old, use the number in your user guide to contact Motorola for a possible warranty replacement.

Best regards.

Icom IC-A6 Airband radio keeps going off when trying to transmit


This is likely the result of a high current draw, ie too high for the battery capacity, which could be simple partially discharged batteries. Have you tried transmitting on low power? Does that make a difference?

It would appear from the voltage that you are using rechargeable batteries such as NiMH which have a lower full charge voltage than alkaline cells. Though I have never used the A6, I do have several Icom handhelds, amateur and marine and they work fine using the NiMH cells, though it is possible that alkalines may help--it's worth a try.

If none of the above makes a difference it would appear that something in the transmitter circuits is drawing too much current. A likely suspect (unfortunately) is the power transistor. Ouch. Good luck. Let us know what you find.

Walkie talkies model gmr325-2 ic;513C-UT914 HOW DO I GET THESE TO TRANSMIT, MY HUSBAND HAS CANCER AND WE NEED THEM IN OUR BEDROOMS AND WHEN I AM OUTSIDE, TK U, TK U


In order to get the most out of your new radio, read this reference guide completely before attempting to operate the radio.

Turning the Radio On and Adjusting the Volume

1) Press and hold the key to turn the radio ON.

2) To change the volume level press the volume/monitor up or down key to increase or decrease the volume level.

3) Press and hold the key to turn the radio OFF.

Adjusting the Sound (Key Beeps)

Your radio emits a beep each time one of the keys (except for the PTT button and call key) is pressed.
The sound of the Key Beep will increase or decrease depending on the volume level setting.

To turn OFF this beep:

Press and hold the call key while turning ON the radio.

To turn ON this beep:

Turn the radio OFF and ON again.

Choosing a Channel

Your GMR325-2 radio has 22 channels you can use to talk to others. In order to speak to someone,
each of you must be set to the same channel.

To choose a channel:

Press the channel/scan up or down key to increase or decrease the channel number displayed.

Channel Scan Feature

Your GMR325-2 radio has a channel Scan feature that allows you to easily Scan all 22 channels. When an active channel is detected, the unit will pause on that channel until the channel is clear. Then after a 2 second delay, the unit will continue scanning.

Pressing PTT button while the Scan is paused on a channel will allow you to transmit on that channel.

To turn ON channel scanning:

Press and hold either the channel/scan up or down key. The channel number on the display
will rapidly cycle through the channels.

To turn OFF channel scanning:

Press either the channel/scan up or down key.

Talking on Your Radio

To talk to others using the radio:
1) Press and hold the PTT button and speak in a clear, normal voice about 2-3 inches away from the microphone.

While you are transmitting the tx icon is displayed. To avoid cutting off the first part of your transmission, pause slightly after pressing the PTT button before you start talking.

2) When you are finished speaking, release the PTT button.You can now receive incoming calls. While receiving, the rx icon is displayed.

Transmitting a Call Alert Tone

Your GMR325-2 radio is equipped with a call tone that will be transmitted when the call key is pressed.

To transmit the call alert tone, press the call key.

The tone will automatically be transmitted for a fixed length of time.

Auto Squelch Feature

The GMR325-2 is equipped with an automatic squelch system which shuts off weak transmissions
and unwanted noise due to terrain conditions or if you have reached your range limit.

Monitor Mode Feature

Your GMR325-2 radio allows you to listen for weak signals on the current channel at the press of a key.

To turn ON monitor mode:

Press and hold the volume/monitor up or down key. The rx icon will blink.

To turn OFF monitor mode:

Press the volume/monitor up or down key. The rx icon will stop blinking.

Automatic Power Save Feature

Your GMR325-2 has a unique circuit designed to dramatically extend the life of the batteries. If there is neither transmission nor an incoming call within 2 seconds, your radio switches to the Power Save mode. The radio is still able to receive transmissions in this mode.

KEYLOCK ON/OFF

Press and hold the call key until the "L" appears. After 1 second, the LCD will return to the channel display.
To exit Keylock on mode, press and hold call again.

Note: While in keylock on mode, it will still receive transmissions.

ROGER BEEP

Roger Beep is a BEEP that is sent to notify the end of transmission.
Roger Beep can be heard through the speaker when Key Beep is on.
Roger Beep is transmitted even if key beep is turned off. However Roger Beep will not be heard from the speaker.

To turn OFF Roger Beep: Press and hold the channel/scan up Key while turning on the radio.

I have 4 radios. Initially they all worked together. Now , een on the ame frequency , they do not all pick up the signal? Any ideas why?


These are FRS/GMRS radios. You may have different privacy codes set on the radios. If a receiving radio has a different privacy code than a transmitting radio, you will not hear the transmission. This allows many people to share the 22 channels, but only hear transmission from their party.

Check your frequency, interference eliminator code and Qt filter to see that they are all set identical on all the radios. Also, in the case of cutting out before a transmission, this can be a sign of a bad battery. It takes more energy to transmit than receive, so you will see failure on the transmit side first. Try a known-good battery to see if it solves the problem.
