Frequently Asked Questions - Tectalk Worker 3 ALBRECHT

The radio does not turn on, what should I do?

Check that the battery is correctly installed and charged. Clean the battery contacts. If the problem persists, replace the battery.

How to choose a channel?

Use the Channel + and Channel - buttons to select one of the 16 PMR446 channels. To communicate with older 8-channel radios, use channels 1 to 8.

Why can't I communicate with my group?

Make sure all members use the same channel and the same CTCSS/DCS code (if enabled). Also check the range.

How to activate the VOX function?

The VOX function is set via the programming software (not included). It allows automatic transmission without pressing the PTT button. Sensitivity is adjustable on 8 levels.

What to do if others hear me with interruptions?

This may be due to a signal too weak (distance) or a defective external microphone. Try to move closer or check the headset.

How to adjust the squelch?

The squelch is adjusted via the programming software on 9 levels. Too low a level causes constant hiss, too high a level suppresses weak signals.

Can I use a headset with this radio?

Yes, plug a headset with a Kenwood jack (specific wiring) into the jack located on the right side. Make sure to close the rubber cover if no accessory is used.

How to activate the alarm mode?

Press and hold the programmable button (side) previously configured for the alarm function. A siren sounds for 20 seconds on the active channel, then the radio switches to reception for 10 seconds. Press PTT to exit.

What does the LED indicator mean?

The LED indicator turns green during reception and red during transmission. During charging, it is red and turns green when the battery is full.

How to save battery?

The battery saver mode can be activated via the programming software (3 levels). It alternates between normal standby and deep standby to reduce consumption. Note that very short transmissions may be missed.

5. Basic operations of the radio

5.1. Battery Charging

Please charge the new battery pack before using it. You can either use the included desktop charger or charge the radios with the USB-C charging cable.

1. Plug the power adaptor into an electric socket and connect it to the desktop charger with the USB-C cable.
2. Insert the Tectalk Worker 3 or the battery alone into the drop-in charging tray.
3. Ensure that the battery's contacts connect with the drop-in charging tray properly. While the charging is taking place, the LED will glow red.
4. After about 3 hours charging, the LED will turn green to indicate that the battery is now fully charged.

Note: A new battery pack will not reach its full capacity after the first recharge. It will take two or three charges and discharges to reach full capacity.

5.1.1. Low Battery Voltage Warning

When the voltage is low, the warning "Please charge the battery" is played every 20 seconds. No more transmissions are possible and the PTT button will sound an alarm tone.

5.2.Installing a headset / microphone

Insert the plug of the headset into the speaker/mic socket on the right side of the radio unit. All accessories with "Kenwood" wiring may be used.

Note: The Tectalk Worker 3 is not water resistant when using external accessories. Close the rubber cover over the sockets if an external headset is not used.

5.3. Selecting a Channel

This radio features 16 real PMR446 channels. These 16 channels have been made available by the authorities just recently. Older PMR446 radios only support 8 PMR channels. If you plan to use the Albrecht Tectalk Worker 3 with older 8 channel radios, only the first eight channels are available.

Channel number	Frequency / MHz	Channel number	Frequency / MHz
1 446.00625 9 446.10625
2 446.01875 10 446.11875
3 446.03125 11 446.13125
4 446.04375 12 446.14375
5 446.05625 13 446.15625
6 446.06875 14 446.16875
7 446.08125 15 446.18125
8 446.09375 16 446.19375

6. Transmitting and receiving

When the radio is switched on, it is automatically in receive mode as long as you are not transmitting. When a radio message is received, the status indicator lights up green.

To transmit, press and hold the PTT (Push-to-Talk) button and speak into the microphone at normal volume and about 5 cm distance. The status indicator lights up red during transmission. Release the PTT button at the end of your transmission.

7. Optional functions (via programming software)

The following options can be changed via programming software (not included, optionally available). The preset values of the radios are:

• Squelch: level 3
• VOX: off
• Programmable button: monitor
• Battery saving mode: off
• Beep at end of reception: on
• Scrambler: off
• Roger Beep: off
• Transmit time limit: on (90 seconds)

7.1. Squelch

The squelch can be set to 9 different levels.

The squelch mutes the speaker when no signal is being received. If the squelch is set correctly, you will only hear noise during reception. If the squelch is set too low, you will constantly hear a slight hiss. If the level is set too high, weak radio transmissions are suppressed.

7.2. Voice Operated Transmission (VOX)

The VOX function allows you to send radio messages without having to press the PTT button. The Tectalk Worker 3 automatically goes into transmission mode when the VOX function detects that someone is speaking into the microphone.

The VOX sensitivity can be selected in 8 different levels: Level 1 means that VOX is activated at very low noise levels. Level 8 means that you have to speak very loudly into the microphone to activate VOX.

With the VOX delay, you set the time after which the automatic transmission mode is terminated without speech. You can set the delay between 0.3 sec. and 3.0 sec.

7.3. Programmable key

The programmable side key of the Tactalk Worker 3 can be assigned to various functions.

7.3.1.Monitor

If you hold down the side button for a long time, the squelch is deactivated temporarily and you can hear all signals including noise.

The monitor function is very useful when you want to adjust the volume or receive weak signals (which would be suppressed by the squelch).

7.3.2. Scan

Press and hold the side button to use the SCAN function.

The unit will then automatically scan all channels for signals. Each channel can be individually programmed to be included in the scan process or not.

If a signal is found during the SCAN process, the radio will automatically stop on that channel.

7.3.3. Scrambler

Use the side button to turn the scrambler on and off. This function distorts the transmitted voice transmission in such a way that it can only be understood by another Tectalk Worker 3 with activated scrambler.

7.3.4. Alarm

Use the side button to send an alarm tone (siren). The alarm tone will be transmitted for 20 seconds on the currently selected channel before the unit switches to receive mode for 10 seconds. Press the PTT button to exit alarm mode.

7.4. Battery save mode

The battery saving mode can be set in 3 levels. It reduces power consumption during use. If no activity (transmitting/receiving) is registered for 20 seconds, the unit automatically switches to battery saving mode (if activated). Depending on the level, the unit then automatically alternates one second of ready-to-receive standby with 2/3/4 seconds of deep standby. No reception is possible during the deep stand-by interval, therefore very short transmissions may be missed.

7.5. Beep at end of reception

Set whether the radio beeps to indicate the end of a received message.

7.6. Roger Beep

Set whether the radio beeps at the end of a transmitted message to indicate the end of the message.

7.7. Channel Busy Display (BCL - Busy Channel Lockout)

The channel busy indicator can be turned on or off for each channel. When activated, the function prevents you from making radio calls on a channel that is already busy. If you press the PTT key in this case, a warning tone is emitted and your transmission is blocked.

7.8.CTCSS/DCS

CTCSS (Continuous Tone Coded Squelch System) / DCS (Digital Coded Squelch)

There are 44 CTCSS and 211 DCS tones available: CTCSS is a non-audible subtone, while DCS is a digital code.

The CTCSS or DCS allow you to block unwanted radio transmissions and only receive messages from people with the same tone or code.

7.9. Transmit Time Limit (Time-Out Timer)

The transmit time-out timer prevents the radio from accidentally blocking a channel permanently. You can set the transmission time limit between 90 and 520 seconds (in 15 second increments). The transmission is automatically interrupted after the set time.
