20 Most Recent Motorola MR355R Two Way Radio Questions & Answers

A few things to check, and some facts about 2-way radio range:

1) Be certain you are using a fully charged battery.
2) Hold your radio upright perpendicular to the ground (antenna straight up) for the best range. Tilting the radio can reduce range significantly.
3) Face the direction you are wanting to transmit.
4) Wear the radio up high on your body. Height and placement of the radio determines range.
5) Double check you have the radios programmed to the exact same frequency and code. Sometimes on a "near" frequency you can transmit to another radio on a different frequency, but it would be poor and short distanced.

2-way radios are line-of-sight communications. Anything you place between the two radios will reduce your range. Outside radio-to-radio in a flat area you should be able to talk up to 2-miles line-of-sight. If you were on a mountain you might be able to talk miles and miles into the valley below. (You can talk as far as you can see in most cases.) If you go inside a building and try to talk from inside to outside you might only get 1/4 to 1/2 mi. Your range will vary according to your circumstances/location.

Most TalkAbout radios are 1/2 watt radios and by comparison business radios are up to 4-5 watts, with some being aided by repeater/trunking systems which would enhance the overall range.

Best regards.

Your radio may be functioning normally for the emergency alert. Here is an excerpt from the user guide:

Emergency Alert Mode

The Emergency Alert feature can be used to signal members in your

group of your need for urgent help. MR series radios will operate in an

automatic "hands-free" emergency control mode for a total of 30

seconds after activating the Emergency Alert. MR series radios in your

group will automatically advance the speaker volume to the maximum

setting and sound a warbling alert tone for 8 seconds. The alert tone is

emitted from your own radio speaker and the receiving radios in your

group. After the 8 second alert, any spoken words or incidental sounds at

your end will be transmitted to the group for 22 seconds. For the 30

second duration of Emergency Alert mode, MR series radio controls and

buttons will be locked to maximize reception of the emergency message.

1. Press and hold the Emergency Alert button for 3 seconds.

2. Release the button after the LED Indicator glows red and the alert tone

begins to sound. There is no need to continue to hold the Emergency

Alert button or use PTT for your message to be transmitted.

3. After the alert tone ends you may speak into the microphone. Your

voice or incidental sounds will be transmitted. The LED indicator will

continue to glow for the duration of the 22 second period.

4. After 30 seconds your radio speaker will emit a Talk Confirmation

Tone and the LED Indicator will extinguish. Operation then returns to
normal two-way mode.

Note: All Motorola Talkabout EM, MJ, and MR series radios are fully

compatible with the Emergency Alert feature. Radios other than EM, MJ,

MR series can receive the emergency alert signal, but will not respond

with adjusted volume settings, locked controls, or a warbling alert tone.

Users of other radio models set to the same channel and Interference

Eliminator Code will hear a steady tone for 8 seconds followed by the

voice transmission for 22 seconds.

Warning: The Emergency Alert feature should only be used in the event

of an actual emergency. Motorola is not responsible if there is no
response to the emergency alert from the receiving group.

There is a good explanation at http://www.twowayradioforum.com/forum/showthread.php?t=762

Your repeater channels, when activated will give you the most range. These 8 channels follow the basic 22 channels and have an R in front of the channel number. As the article at the link above says, you need a license and permission to use the repeater, if one is available in your area.

No. Your Talkabout radio operates on UHF and your wife's walkie talkie is a VHF radio operating on exclusive business frequencies.

Check your Private Line (aka interference eliminator code, tone code, PL, quiet call). It sounds like you have one radio set with a PL setting and the other one is open squelch (no private line). All settings for frequency and PL code need to be the same between the two radios.

We don't have a manual for the T3, but I am attaching one for the T5, which may be similar. http://www.motorola.com/web/Business/Products/Two-Way%20Radios%20-%20Unlicensed/_Documents/TLKR-T%20series/Static%20Files/T5%20Manual%20EU.pdf
