Ok. I figured out how to change the voice prompt. I uploaded one that I made, but it won't blame over the pager and I can't seem to find it in the drop down on the channel setting.
If you'd like I can send you a copy of the codeplug for my G1 to look over, or if you want to send yours to me I'd be happy to take a look at it.
***Follow these steps when adding custom tones & voice prompts:
1) After putting the pager in the cradle you need to click on the Music Alert / Voice Prompt Programming tab.
2) Then in the respective categories add your custom tones and voice prompts, and next click the "Write Pager" button at the bottom.
3) After you get the message that the programming was successful then click the "Program Pager with Read Pager Codeplug Data"
4) After the pager has been read then click on Tab H: Receiving Portfolio Setting (Provided you've set up the channels on whatever knob positions you want)
5) Double click on whatever channel/knob position you'd like to add the voice file to.
6) When that window opens in the top section with the green header bar labeled "Knob Function Setting" at the very bottom you'll see the "Voice Prompt Index" field. As long as the voice file was successfully wrote to the pager this is where it will show up. Remember, this field is only for the voice prompt, not for custom tones when the pager alerts. This is basically like the channel announcement feature in Motorola radios, which I'm sure you know but I wanted to say that just in case,
7) Click the down arrow in that box and as long as the voice prompt was written successfully you'll be able to select it. After selecting it if you click the "Play Pager" button it will play that prompt through the pagers speaker as long as it's still in the programming cradle.
Follow those same steps for other channels as needed. Let me know if this clears things up or helps. And again, if you're still having issues I'd be happy to take a look at your codeplug. Also, make sure your pager is running the most current firmware which is: RVV0114EN .
