Talk Permit Tone & talk range

Why the double beep matters, and how far you reach.

›

The Talk Permit Tone (TPT) is the quick double beep after you press PTT. It confirms the channel is clear and keeps people from talking over each other. Always wait for it to finish before speaking.

EnvironmentTypical range
Inside steel / concrete industrial buildingsUp to 300,000 sq ft
Inside multi-level buildingsUp to 20 floors
Same fleet, same settings For radios to hear each other they must share a channel and the same PROFILE ID. Default PROFILE ID is 0000. Change it to a private 4-digit number to avoid interference from nearby radios.
From the manual — MN007944A01-AH, p. 31
"For a group of radio to communicate, all the radios need to be on the same channel and have the same radio PROFILE ID number. The default PROFILE ID number is 0000. ... The radio in your fleet, independent of the channels that users are assigned to should use the same PROFILE ID. Customize the PROFILE ID number to avoid interference from other users using the default 0000 number."

Troubleshoot

FAQ

The fastest fixes for the issues that generate support calls. If none of these clear it, talk to a specialist.

The radio will not power on
Recharge or replace the Li-ion battery. Extreme heat or cold shortens battery life and can prevent power-up. Confirm the battery is fully seated (see Attach the battery under Start Here).
CPS cannot read the radio
Check that one end of the programming cable is on the radio and the other is in a USB port. Verify the cable switch is set to Digital (or Flash on older cables). Make sure the radio is seated correctly in the Single-Unit Charger.
No audio when I press PTT, or a continuous tone
For a continuous tone, press PTT again once the receive cycle ends. For no transmit: confirm nobody else is on the channel, and if using an earpiece make sure the radio PTT is disabled and you transmit with the in-line PTT.
I hear traffic that is not from my team
Set a private 4-digit PROFILE ID on every radio in the fleet. The default 0000 is shared by all radios out of the box, so a custom PROFILE ID isolates your group.
Audio sounds garbled or robotic
You are near the edge of range. Digital audio stays clear almost to the limit, then breaks up just before the signal drops. Move closer or improve line of sight.
My transmitted audio is too quiet
Hold the radio vertically, 1 to 2 inches from your mouth. With an accessory mic, hold it 2 to 3 inches away. If it persists, raise MIC Gain in Advanced Configuration Mode.
A loud tone keeps interrupting the conversation
Do not release PTT mid-transmission and immediately re-press it. Hold PTT firmly until you finish speaking, and confirm the channel is free with a user in range.
Talk range feels short
Keep clear line of sight and avoid steel, concrete, heavy foliage, and vehicles. Do not carry the radio tight against your body in a pocket or on a belt. Coverage is strongest inside industrial and commercial buildings.
Echo, feedback, or heavy static
Lower the volume and keep transmitting and receiving radios apart, at least five feet, and use an earpiece if needed.
The charger LED will not blink or the battery will not charge
Verify the radio or battery is fully inserted and the contacts are clean. Confirm the drop-in charger is connected to a compatible power supply. Check the charger LED for an error state (fast blink red means reposition the battery).
