Function Setting
PC Software Programming Setting
Please login in http://www.nanfone.com to download to NF-910 software. Or ask for the local
distributors.
SQL Setting
1. Open the PC software to select the squelch level you require on the right corner
Squelch level is from 1-9. The higher the squelch level, the lower chance of interference, but it
may affect the communication distance.
2.Squelch system can eliminate background noise when there is no signal received, which not
only make it more comfortable at standby mode, but also significantly reduces the standby power
consumption.
VOX Function
1. Open the PC software, you can select the squelch you require, like the picture .
The level of VOX is from level 1 to level 10. The higher the lever is, the higher the sensitivity will be.
2. VOX Postponement: If the transceiver returns to receiving mode immediately after launch, the
end part of the call may not be transmitted correctly. Such kind of problem can be avoided by
setting VOX Postponement.
15

TOT
1. Open the PC software programming to select the times . The purpose of the
Time-out Timer is to prevent any single person from using a channel for an extended period of time.
2. The overtime can be set by PC software programming ( the time can set as 30 seconds, 60
seconds, 90 seconds、120 seconds、150 seconds、180 seconds or OFF ). If the continuous
launching time is over the preset timer, the launching will be stopped and a “Beep” tone sounds.
To stop the “Bi” tone, please release the PTT button. You can press the PTT button again to
resume launching.
Oral Channel Indicator Function
Open the PC software to select the language. When the oral channel indicator
function is programmed to be off, then the transceiver will not report the channel. When the oral
channel indicator function is programmed to be in English or in Chinese, then the transceiver will
report the channel accordingly.
Scan Function
1. Open the PC software to select the scan should be turned on or not.
2. There’re scan function options behind each channel if the function is selected. When the scan
function is set to be ON, the channel can be scanned automatically in standby state, and you can
talk on this channel while there’s signal. Rotate the channel selector to channel 16 to activate the
16

scan function, and then those channels which set automatic scan will be activated by it-self. For
instance, if the scan function of channel 3,5,7 was activated by PC software programming, when
you rotate the channel selector to channel 16, the transceiver will scan channel 3,5,7,16, when
receive signal from one of these four channels, it will stop scanning, and talk on this channel.
It’s normal that it will be delayed when you open the speaker after activating the scan function,
the delay time is related to the number of channels which set scan function.
Note:
If the channel with CTCSS/DCS, if it is disturb by signal with CTCSS/DCS or not during scanning,
the radio light will bright green and quit scan. The speaker is also without sound. It must wait for
10 seconds after the interference, which is normal.
