Can this radio be used to receive alerts from the Dakota Alert products?
Yes. You need to program the correct frequency and CTCSS tone and set the bandwidth to narrow. Out of the box set up for the Dakota Alert MAT and MAPS sensors is 151.820 MHz and CTCSS of 67.0 Hz. On some radios you may need to turn off the receive CTCSS tone to hear the whole alert message. Data is also transmitted by the MAT and MAPS and this can sometimes interfere with CTCSS decoding on some radios.
Do I need to “break in” my batteries?
In some cases it helps to perform a “forming” charge on your batteries. This can be accomplished by fully discharging your radio (leave it on until it powers off), then fully charge the battery again (about 24 hours). Repeat this cycle one or two more times. This will help to maximize the capacity of the battery.
Why does the charger not charge the battery if it there are two or three bars on the battery indicator?
If your battery is not discharged low enough the charger may not detect that the battery is ready to be charged. It is recommended that you discharge your battery as much as possible prior to recharging it. Full discharge and recharge cycles will maximize the battery’s life.
My charger doesn’t seem to be working. None of the lights turn on when I put the radio in the charger.
In order for the battery terminals to contact the chargers terminals the radio must slide into position properly. There are two slots on the side of the radio’s battery that need to slide onto the two vertical rails inside the charger. This will align the terminals so that they will come into contact with each other and charge the radio.
