Question about Garmin Rino 120 2-Way Radio

1 Answer

Overheat/battery drain I was using my 120 at night and used the LED light a few times and it suddenly got really, really hot even though I turned it off. Now it will still turn on and works correctly but it will heat up almost immediately and drain a set of three new batteries in less than an hour.

    I have four 120's and have the exact same problem with only one of them. Put new batteries in and within one hour (even less) the unit is uncomfortably hot to the touch and the batteries are dead. This is not from use, rather the unit was sitting on my desk out of the sun.

    my 120 runs through batteries when on or off, the only way to stop the drain is to remove the batteries

    I have the exact same problem, the Rhino GPS overheats almost too hot to hold like it has a short in it.

Hello dogwillhunt,

It is normal for a two-way radio to generate some heat, especially during extended periods of long talk time. Consumer two-way radios tend to be much more susceptible to this because they tend to be constructed out of materials that do not dissipate heat very efficiently, such as polycarbonate and plastic. Periods of heavy transmit times also use additional power, causing the radio’s batteries to run down more quickly and require replacement or recharge. Use of the display backlight feature can generate additional heat and run the unit out of battery power even more quickly.

If the radio is heating up excessively and burning through batteries (pardon the pun) in situations where you are not using the LCD backlight excessively or transmitting for long periods of time, this may be indicative of a problem with the unit that would require service, such as a short or defective component. If such is the case, I would recommend contacting the manufacturer.

Motorola radius cp200 will not hold a charge


when charging a new battery for the FIRST time, most require a full 24 hours to be properly charged. Failing to do this will drastically diminish the life of the battery. If you did fully charge the battery the first time, another issue is recharging after EVERY use vs charging when completely drained. Battery will develop memory (although the manf. will say other wise). If you charge after every use and have only used a third of the charge, after a few time of doing this, you will notice that the battery will not last as long. Try one more battery in just one raido. Fully charge it the first time and only recharge when COMPLETLY drained. If the battery is still not holding a charge, it is most likly a short in the radio itself. Return it.

I have a Motorola MR350 and have been using the pair for several months now. I must say, the coverage is pretty good and I really enjoy the design. However, last night when I turned it on, the user on...


It is possible you have one rechargeable battery pack getting weak. Try swapping the batteries, and see if the problem leaves, or changes to the other radio. Typically when batteries start to go bad a common sign is hiss, static, no transmit, or intermittent transmit.

If you do find it is a battery problem, then check your chargers. You could have one charger causing the problem, or simply dust/debris on the charge contacts. This can happen from hand oils getting on the contacts, and then over time dust accumulates and creates a barrier between the charger and the radio. These can be cleaned with a pencil eraser.

Always be certain the radios are turned off when on the charger.

If the battery and/or charging set up is not the problem, then you have a radio problem. If it is the radio, you will likely need to replace it. Parts and schematics are not available for this model.

Best regards.

Yaesu VX-3R ham radio will not turn ON!!!!


Even though this is several months old, I thought I would post this reply. I had the same problem when I ran the battery completly down. The charge light didn't come on and the unit would not turn on with the power or battery. Sent the unit back to Yaesu for warranty work and they replaced the switch board. Unfortunately after I got it back and ran the battery down again..... Well, it's back at Yaesu AGAIN! Looks to me like there could be a problem with the power circuit being overloaded when it tries to charge the flat battery!!
Nice little rig, but it may be for sale once I get it back!!

Charger should be able to power the radio at 'EL' level, if NOTHNG happens, I'd say charger is on the blink.

Batteries die quickly - unit gets hot


You may have a bad or shorted battery pack. You might try replacing it to see if the problem goes away. It would be normal, while charging for a battery to get warm. But not hot. Rechargeable batteries have a life expectancy of 18-24 months.

Yaesu FT-50R battery drain


scotwho, I personally do not know the radio you are asking about, but I do have many years working with radios in troubleshooting. What I am guessing is, if the heatsink gets hot, then whatever is connected to the heatsink has shorted out. Two main parts come to mind here, and that's the audio chip, and the transmitter output final/chip. Possibly the main IC (brain) that controls most everything, but I doubt that. The radio needs to go to a repair shop that can troubleshoot the damage/ and find an answer as to why it occurred. A lot of times the factory's do not use heatsink compound when they assemble the units, and after an x amount of time the part/parts will fail. 10cents worth of heatsink compound can make a radio last a few years longer.
Probably not the answer you wanted but I hope this helps,, let us know. Mechanic

Batteries in my Rino 120 don't last very long


I believe its 3AA's and it SHOULD last 15 hrs of life. You should probably check the terminal heads and clean them real good you might be shorting somewhere in the connection.
