Chapter  4  Function  Description  and  Parameter 

Setting 

4.1 Major Functions 

4.1.1 16 Channels

The radio stores 16 channels.

4.1.2 Scan Channel (programmable by PC software)

a)    Press  the  key  designated  as 

“

Scan

”

  to  activate  scanning. 

While in scanning, the radio checks every channel and stops on the 

channel on which a signal is detected until that signal disappears. If 

the  delay  time  between  signal  disappearing  and  continuing 

scanning  has  been  preset,  the  radio  will  remain  on  that  channel  in 

the delay time even receiving any signals at that time.

Only  when  there  are  two  channels  added  in  the  scan  list  and  the 

scan function has been activated, the radio can start scanning.

b)  The  dealer  can  set  the  revert  channel  (transmitting  channel)  in 

scanning among the following options:

1) 

Selected: 

The  radio  always  reverts  to  the  channel  selected 

before scanning when pressing PTT.

2) 

Se Talk Back:

 When the radio is in scanning, press the 

PTT  button  and  the  radio  will  transmit  signals  on  the  selected 

channel.

When the radio is in scanning pause, press the PTT button and the 

radio will transmit signals on the current talk back channel.

3)

Priority:

  When  pressing  PTT,  the  radio  will  transmit  signals  on 

the priority channel in the scanning list.

4) 

Priority  +  Talk  Back: 

When  the  radio  is  in  scanning,  press  the 

PTT  button  and  the  radio  will  transmit  signals  on  the  priority 

channel. When the radio is in scanning pause, press the PTT button 

and the radio will transmit signals on the current talk back channel.

5) 

Last  Called: 

When  pressing  PTT  button,  the  radio  will  transmit 

from  the  last  channel  that  received  a  call.  If  it  has  never  received 

any calls, it will revert to the first channel in the scanning list.

6)  

Last Used: 

When pressing PTT button during the scanning, the 

radio will transmit from the last channel that you used to transmit. If 

it has never made any calls, it will revert to the first channel in the 

scanning list

c) Priority Scan

During scanning, if the priority channel has been set on the radio, 

when the priority channel receives a signal the radio will 

automatically switch to the priority channel even the normal channel 

is receiving signals at that time. And the radio will stay on the 

priority channel till that signal disappears. The dealer can set the 

delay time between signal disappearing and continuing scanning.

d) Temporarily Delete

When scanning pauses on a channel,channel,  press and hold the 

button programmed as 

“

Temporarily Delete

”

 or 

“

Scan + 

Temporarily Delete

”

 for 1 second to delete this channel temporarily 

from the scanning list.

Note:

 The priority channel cannot be deleted. And when the number 

of scanning channels is less than 2, you cannot delete any channel, 

either.

After exiting scanning mode and entering it again, the temporarily 

deleted channel will be added in the scanning list again.

4.1.3 CTCSS/DCS

CTCSS/DCS can realize selective calls and group calls. On the 

same channel, only the two parties whose CTCSS/DCS are 

identical can communicate. CTCSS/DCS signaling code on the 

channel is preset.

4.1.4 TOT

The purpose of the time-out timer is to prevent any single person 

from overlong using a channel to transmit and affecting the whole 

group communication.

If the radio transmits longer than the preset TOT time limit, the radio 

will stop transmitting and warning tone sounds. To stop the warning 

tone, release the PTT button. Press the PTT again you can resume 

transmitting.

TOT Pre-Alert:  

You can set the time when the radio generates a "Pre-Alert tone", 

before the TOT (Time Out Timer) expires. TOT will expire when the 

selected time passes after a 

“

Pre-Alert Tone

”

.

TOT Rekey Time: 

TOT Rekey-Time sets the "penalty" time in which the radio cannot 

be re-keyed for transmitting after the Time Out Timer setting is 

exceeded. During the Rekey time, if you press PTT, warning tone 

sounds and transmission is prohibited.

TOT Reset Time: 

TOT Reset Time sets the minimum "wait" time allowed between 

transmissions that will reset the Time Out Timer. After setting this, 

TOT continues even after PTT is released unless the TOT Reset 

Timer has expired.

4.1.5 Auto Power Save

When no signals are being received or no operations are being 

conducted for over 10 seconds, the battery power saving will be 

activated to reduce power consumption. When it is receiving signals 

or in operating state, battery power saving is inactive. 

Power Save Type: 1:1, 1:2, 1:4, and OFF.

4.1.6 Low Battery Warning

When the battery power appears low, the indicator flashes. If the 

battery power is lower than the preset value during transmitting, the 

status indicator flashes red. When the speaker sounds warning 

tone, the radio will stop transmitting.
