Hello RR I have a Uniden SDS200 scanner. I programmed tone out codes for Cumberland fire department station 4 where my friend is a firefighter. After successfully programming the correct tone codes verified by first using tone out search, when I press menu knob, scroll to tone out for... I press tone out standby. Now the problem I'm having is that I don't get any audio even if the programmed tone is activated by dispatch. The only way I get alert and audio is when I press HOLD then RESUME soft keys when in tone out standby mode to activate it. Is there anyone else that has to do this to get it working or did I do something wrong? Thank you
SDS100/SDS200: Tone out standby
- Thread starter DH11
- Start date
When you press Tone-Out Standby, do you see the frequency of interest displayed along with what you named the tone-out(s)? Also, do you see the correct A and B tones displayed?
Yes I see the frequency 482.7375 MHz and A 410.5 HZ and B 510.7 HZ but like I mentioned In tone out standby I don't get any audio unless I press HOLD then RESUME to activate it Then when dispatch hits the tones I get my programmed alert blinking light alert tone and I hear the dispatcher and apparatus transmissions According to a Uniden technician when I called I shouldn't have to press HOLD then RESUME to get audio but with all do respect to Uniden that is not the case for me
I'm wondering if it may be something like that frequency's Service Type is not selected.

No, the Uniden SDS200 scanner does not require you to press HOLD then RESUME to activate Tone-Out Standby; you simply navigate to the Tone-Out menu, select "Tone-Out Standby" from the menu, and then tap SCAN to exit the Tone-Out mode.
To activate and use Tone-Out Standby:
Access the Menu: Tap the MENU button on your SDS200.
Select Tone-Out: Scroll to and select the "Tone-Out" option from the menu.
Start Standby: Select "Tone-Out Standby" to begin the search. The scanner will start searching the last-used Tone-Out channel or any other channels with the same frequency.
Change Channel (if needed): If you need to search a different Tone-Out channel, turn the SELECT-VOLUME-SCROLL knob until you find the desired channel.
Exit Tone-Out Mode: To exit Tone-Out mode, tap the SCAN button.
Important Information about Tone-Out Standby:
No Audio: While in Standby/Search mode, transmissions on the frequency are not heard.
Signal Strength: You will still see the signal strength bars for any detected signal.
Temporary Exit: Pressing the Channel button will temporarily exit standby and allow you to hear transmissions, but alerts will not sound.

I shot an email to Rich Carlson, a former employee of Scanner Master. He has more scanners than Uniden and Radio Shack combined. He used two different Uniden SDS200 scanners set side by side bot set to tone out standby both programmed tone out codes the same. On one scanner he pressed HOLD then RESUME and on the other he didn't and sure enough the scanner without pressing HOLD then RESUME ignored to tone and remained silent while the pressed HOLD then RESUME scanner successfully activated and audio was heard. Rich with all of his experience in scanners says that it's weird and that he will reach out to Uniden and request a software update. Thank you for getting back to me
Try increasing the delay time.
I was able to replicate the conditions identified by user DH11. It was referred to Uniden and they were able to replicate it as well and it will be fixed with the next firmware update. I don't know when that will be issued but it should be pretty soon. In the meantime DH11 identified a workaround in case others are experiencing the issue.
