MT1500 shows full battery but beep's like it's dead


Hello
This double beep tone you are hearing is a acknowledgment tone indicating that the radio is in the transmitting mode. On the Motorola MT1500 radio you can adjust the tone volume separate from the reception volume by simply holding down the volume control and setting the tone volume level.
I hope this helps.

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.

Will not get good recepiton.


Hi stormnorm157,

Much of the time this is caused by problems in the antenna system. Make sure there are no shorted or open connections in the coax or PL-259 connectors. Use your radio's meter or better still, a Power/SWR meter to check the SWR of the antenna. Try to get that as close as possible to a 1:1 ratio on the meter. A shorted or open antenna can keep the audio receive on your radio at very low levels. Plus, this will harm your transmitter if you continue keying the mike.

Another problem can be in the radio itself. This will be noticed if you can transmit, but have no "Modulation". Modulation can be described as the voice heard above the "Carrier" (your transmitted signal). Every CBer knows about the term, Modulation. The Truckers will definitely inform you about your modulation quality...lol. This problem can be due to a defective AMC (Automatic Modulation Control) stage in the receiver circuit. And, there will be no modulation upon transmit.

One other thing could be causing this lack of receive. Defective wiring or switching in the microphone can result in no audio. Or, in many radios, a missing mike will not allow receive, because the mike connection completes the RX (Receive) circuit.

Solutions:
1. Check the antenna system, and rule that out or fix.
2. Check mike, or substitute another one.
3. Using meter, and or another radio for listening on same channel, check power and receive.
4. You can probably fix 1 and 2 yourself, or with a friend.
5. AMC problem in radio (as described above) will require professional service.

Let me know how this turns out, and inform me if I can offer any more help. Thanks.

Regards, Bill

Radio will "receive" but not "transmit". Radio, antennas, and wiring are all less than two years old. Should I try a new mike?


Firts you have to check for carrier.For this you need an swr meter.2) Check continuity between the pl259 tip and antenna.3) Check for modulation (voice) if all of the above are OK. 4) Check if your display changes to transmit when you press the mike. IF all fails,then try another mike.

Mic hum


Yes, the wiring is different. Reverse the wires on pins 1 & 2, then reverse the wires on pins 3 & 4.

The wiring for you radio's mike is:

1- Audio
2-Ground (Shield)
3-Receive
4-Transmit

Depending on the vintage of your mike, the colors Uniden uses for these functions are white or yellow for audio, red is transmit & black is receive.

Muting the sound


Hi,

The sound produced by a Motorola radio when the mike is keyed refers to the "Transmitting Call Tone" which is another feature other than the "Interference Eliminator" or the "Roger Beep" feature.

On most Motorola GMRS/FRS TalkAbout radios, setting the "Call Tone" to 0 disables the feature. This is done with the radio ON by pressing on the "Menu" button 3 times which will result in the display showing the current Call Tone setting (flashing) and the letters CA; pressing on the <- or +> buttons will change selection (you will also hear the different Tones), select 0 (it may be up to 5 or 10 depending on the version). Press on the "Menu" or "PTT" button to set, save and exit.

Hope that this be of some help/idea. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.
