carrier. The speaker can be unmuted only when the CTCSS/CDCSS received by the receiving party is
matched with that transmitted by the transmitting party.
21
Operation
Enable or disable this feature via CPS by your dealer.
8.13 Squelch Off
Description
With the Squelch Off Momentary feature enabled, your radio’s speaker will keep unmuted no matter
whether carrier is present.
Operation
Press the programmed Squelch Off key to enable the feature (a high-pitched tone sounds), and then
the radio will display the icon
and sounds background noise. Press this key again to disable the
feature (a low-pitched tone sounds).
Hold down the programmed Squelch Off Momentary key to enable the feature (a high-pitched tone
sounds), and then the radio will display the icon
and sounds background noise. Release this key to
disable the feature (a low-pitched tone sounds).
8.14 TDMA Direct Mode
Description
TDMA (Time Division Multiple Access) Direct Mode allows the radio to divide the 12.5 kHz channel into
two alternative slots in direct mode. If the radio operates on a channel with this feature enabled and one
time slot is already occupied, it can transmit and receive in the other free time slot.
Operation
Enable or disable this feature via CPS by your dealer. With this feature enabled, you can manually
switch to a digital channel in TDMA Direct Mode or enter the TDMA Direct Mode by powering on the
radio on a digital channel in TDMA Direct Mode. Under TDMA Direct Mode, the radio will display the icon
8.15 VOX
Description
VOX allows you to trigger the voice transmission by speaking directly without holding down the PTT key.
When the voice detected by the microphone (either external or internal microphone) reaches the volume
to trigger the transmission, it will be transmitted automatically.
Caution
Follow the instructions below when using the VOX feature:

To use the VOX feature with an external microphone, make sure the PTT/VOX switch is switched
to “VOX” before the radio is powered on and the VOX feature is enabled.
22

The VOX feature will be enabled for all the channels.

The VOX feature settings will not remain unchanged when the radio is powered on and off.

After the VOX feature is enabled, switching the PTT/VOX switch to “PTT” will disable the feature.
In such case, switching the PTT/VOX switch to “VOX” will keep the radio transmitting. To make
the radio function properly, reattach the earpiece to enable the feature again.
Operation
Activating or deactivating the VOX feature
 Go to “Menu -> Settings -> Radio Set -> VOX” to enable or disable this feature.
 Press the programmed VOX key.
Adjusting the VOX Gain Level
Go to “Menu -> Settings -> Radio Set -> VOX -> Gain Level” to adjust the transmission sensitivity.
Higher gain level can bring lower sensitivity and thus larger voice volume.
Note
Please adjust the VOX Gain Level properly to avoid unexpected VOX triggering due to high
sensitivity or triggering failure due to low sensitivity.
8.16 CDC/CTC Selected
Description
CDC/CTC Selected allows you to select and configure the appropriate CDC/CTC manually.
Operation
Press the programmed CDC/CTC Selected key on an analog channel to enter the CDC/CTC editing
mode. Use the Up and Down key to select the appropriate CDC/CTC. If a reversed CDC is needed,
press the Cancel/Return Key (the last English character of the CDC will be changed from N to I,
indicating the CDC is reversed). Finally, press the OK/Menu key to save the configuration.
To restore the CDC/CTC programmed by CPS and exit the CDC/CTC editing mode, press the Call End
Key in the CDC/CTC editing mode.
Note: The CDC/CTC Selected feature is used to temporarily change the CDC/CTC of the current
channel. Restarting the radio or switching the channel will restore the CDC/CTC programmed by CPS
for the current channel.
