6.4. Hands-free function (VOX)
With the VOX function, you can transmit wireless messages without pressing the PTT button. The
Tectalk Outdoor automatically goes into transmission mode as soon as the VOX function detects
that someone is speaking into the microphone. The VOX function has the following levels: off, low
sensitivity (lo) and high sensitivity (hi).
6.5. Two-channel monitoring
You can specify a channel to be monitored along with the current main channel. Wireless messages
on this additional channel are also put out via the speaker.
6.6. Key tones
This function enables/disables the key tones that confirm each button press.
6.7. Busy Channel Lock-Out (BCLO)
When activated, the function prevents wireless messages from being transmitted to an already
occupied channel. If you press the PTT button in this case, your transmission will be blocked.
6.8. Transmission power
In cases where the maximum range is not required, the transmission power can be reduced to about
10% of the output power. This increases the average battery life of the device by up to five hours.
6.9. Roger Beep Signal
The Tectalk Outdoor can automatically append a signal tone to your wireless messages in order to
signal the end of a message to your conversation partner. There are three different signal tones to
choose from.
6.10. Standby indicator
If this function is enabled, the battery icon on the display lights up briefly once every 25 seconds in
standby mode. Therefore you can see that the device is still able to receive messages. This function
reduces the average battery life by about an hour.
6.11. Reset
Here you can select the desired function (1 - reset to defaults; 2 - reset to defaults except for the
currently selected channel and subchannel (CTCSS/DCS). Use the
PTT button
to confirm the
reset.
7. Additional functions
7.1. Monitor
The monitor function is very useful if you want to adjust the volume or receive weak signals (which
would be suppressed by squelch). Squelch will be disabled for a short time and you will hear all
signals including background noise. To activate this function hold the function button and then
press the main menu button . Press one of the two buttons to disable the function again.
Please note: it is recommended to turn down the volume in advance!
7.2. Channel search
To automatically search all channels for signals, keep the function button pressed and then press
the ▼ button. If a signal is found during the channel search, the walkie-talkie will automatically
stop on that channel. The channel search continues if the device no longer receives any wireless
messages for more than 5 seconds. To stop the channel search, use the same button combination.
