RT Systems programmers work with the radio specified from the manufacturer shown in the description.
No implication is made that a programmer is appropriate for a radio with a similar number from a different manufacturer. Actually, purchasing a programmer for a radio from a different manufacturer just because it has a similar number is strongly discouraged.
RT Systems takes no responsibility for the performance of your radio should you choose to use a programmer other than that listed specifically for the manufacturer and model of that radio you are attempting to program. Exceptions are noted in the description for several products. Check there if you feel your radio is a variant of the one shown, but be advised that the manufacturer will never vary. If the model is not listed, you should check with RT Systems prior to your purchase.
Installed software is NOT returnable, exchangeable or returnable.
