DETAILED FUNCTION DESCRIPTIONS

1) Scan & Scan Mode setting (SCAN&SCANS---MENU 1&17)

Functions:

under VFO/MR/CH mode, the transceiver allows you to scan the entire current operating band and memory channels.

Enter Menu 1  and press [        ] key to start scanning.

When you have started scanning, press 

 [        ] /

 

[        ]  

key to change direction.And it will halt on a signal it encounters, press 

 [        ] 

key 

to stop scaning Scanning operation is basically the same in each of the above modes. Before you begin,take a moment to select the way in 

which you would like the scanner to halt on a signal.

Enter Menu 17th to set scan mode. Default: TO.

Three options for the scan mode are available under VFO mode:

TO: In this mode, the scanner will halt on a signal it encounters, and will hold there for some time. If you do not take action to disable the 

       scanner within the time period,the scanner will resume even if the stations are still active.

CO: In this mode, the scanner will halt on a signal it encounters, and will hold there if the stations are still active. And after the carrier has 

       dropped, the scanner willresume.

SE: In this mode, the scanner will halt on a signal it encounter, it will not restart automatically; you must manually re-initiate scanning if you 

       wish to resume.

2) Priority Transmit (TX.SEL---MENU 2)

Functions:

This transceiver allows you to transmit on the sub band even if you are working on the operating band.

Enter Menu 2nd to select priority transmit band. Default: EDIT.

EDIT: It will transmit on the operating band.

BUSY: It will transmit on the band last talking used

3) VOX Level & VOX Switch (VOX&VOX.SW---MENU 3&13)

Functions:

 the VOX function provides automatic transmit/receive switching based on voice input to the microphone. With the VOX switch ON, 

you do not need to press PTT switch in order to transmit, and it is not necessary to use a VOX headset in order to utilize VOX operation.

Enter Menu 13th to set VOX switch. Default: OFF.

Enter Menu 3 to set VOX level, it has 7 grades.

The higher level is, the more sensitive will be.This transceiver provides for adjustment of “ Hang- Time” of the VOX (the transmit-receive delay 

after the cessation of speech) via program software.

Default: 2s

.

4) TX Power setting (POW---MENU 4)

Functions:

 you can select high/low TX power according to your talking environment and need. When you store memories, you can store High 

and Low power settings separately in each memory.

Enter Menu 4th to set TX power.

High: 4W

Low: 0.5W, when you select Low power, the “L’ icon will appear on the display.

5) Squelch Adjustment (SQL---MENU 5)

Functions:

Squelch system allows you to mute the background noise when no signal is being received. Not only does the Squelch system

 “standby” operation more pleasant, it also significantly reduce battery current consumption.

Enter Menu 5th to set SQL level. Default: 5.

6) Dual Wait/Standby (D.WAIT---MENU 6)

Functions:

This transceiver allows you to receive the sub band signal even if you are working on the operating band. 

It could monitor the signal under both master and sub band at the same time.

Enter Menu 6th to set Dual Wait. Default: ON.

7) LED Display Mode (LED---MENU 7)

Function: 

select the LED/Keypad Lamp mode.

Enter Menu 7th to select LED display mode. Default: AUTO.

10) Preset Channel Selection(DT/2T/5T CH-MENU 10)

Functions:

Preset the signal type(OFF/DTMF/2T/5T) at software,by choosing 1-16 channel to achieve remote kill/stun/activate/revive function.

Enter Menu 10th to choose 1-16 channel.

11) Transmitter Time-Out Timer (TOT---MENU 11)

Functions: 

the TOT feature provides a safety switch which limits transmission to a pre-programmed value. This will promote battery 

conservation by not allowing you to make excessively-long transmissions, and in the event of a stuck PTT switch it can prevent interference to 

other users as well as battery depletion.

Enter Menu 11th to set TOT. Default: OFF.

12) Busy Channel Lock-Out (BCLO---MENU 12)

Functions: 

the BCLO feature prevents the radio’s transmitter from being activated if a signal strong enough to break through the “noise” 

squelch is present. On a frequency where stations using different CTCSS or DCS codes may be active, BCLO prevents you from disrupting 

their communications accidentally (because your radio may be muted by its own tone decoder).

Enter Menu 12th to set BCLO. Default: OFF.

OFF: Disable BCLO feature.

WAVE: the radio’s PTT will be prevented only if the frequency is busy used.

CALL: the radio’s PTT will be prevented only the frequency and tone coder is the same.
