Here is a link to the user guide for the Motorola TalkAbout T5720. I only could find it available in English. You will need to translate into Indonesian.

Best regards.

Can motorola talkabout T5720 FRS/GMRS talk with Motorola GP338 UHF?

Your GP338 would need to be reprogrammed to one or more of the frequencies available in the T5720. If you are using the interference code eliminator, it would also need to be programmed into the GP338. Take your GP338 to your local Motorola dealer for reprogramming.

Here is a link to the user guide for the T5720, where you will find a list of frequencies: See page 19.

RPL & TPL tones used in T-5720

The T5720 user manual does not list the TPL codes possible in the radio. However, they are the standard list, with zero being "open squelch" (no code). Here is a link to a Motorola manual which has a list of the PL codes in order on page 43.

On the T5720, another item to what for is the Qt noise filter. Be certain to set it to zero unless using the T5720 with others of the same model. It can also block transmissions. Here is a link to a user manual for the T5720

Talkabout T5720 Frequencies

Hello Ruaal,

The frequencies in the TalkAbout T5720 are not adjustable. The radio operates on the designated Family Radio Service channels located at 462 and 467 MHz. There is no way to change these channels to be at 463 and 464 MHz.

Best regards,
Go Ahead. Use Us.

If you are using vox (voice activated transmit) go into the menu and make sure you don't have the VOX setting too high. You should be able to put the headset on... hit the "push to talk" button on the radio and transmit you audio. Turn the other radio on and make sure the radio is "keying" (tx with no auio) then make sure there is audio. If you don't have audio but the radio is transmitting.. you might have the wrong type of plug on your headset for the audio..... there are 2 plugs... 1 for transmit audio....1 for recieve audio. It could be the wrong type of plug for the jack in the radio. Regardless.. the way the headset works is either you push the "push to talk button" onj the radio OR you use the VOX function... with the vox function you just have to talk into the mic to transmit. This is what your headset is designed for. You will have to go into the menu and set up the radio for VOX. If you still have problems follow my directions at the top of this page ( check mic jack and stuff) I think you just have to set the radio up for VOX operation and set the VOX setting. You should be able to push the push to talk button and talk through the mic on the headset. If you don't get any audio that way there is a problem and you should check the jack and plug on the headset.
