Chapter 4 Function Description and Parameter Setting

Major Functions

4.1.1 128 channels

The radio stores 128 channels and can allocate there channels in 8

different zones

Zone 0

cannot be programmed and includes

all channels

8 Zones

There are 8 zones numbered from

Except

Zone0

all other zones can be freely allocated with up to 16 channels

Zone0

includes all channels and cannot be programmed. Only

when the previous zone is allocated with at least 1 channel can the

following zone be allocated.

4.1.3 Channel scanning (this feature can be disabled by

programming software)

There are 16 scanning lists, each of which can be allocated with up

to 16 channels, which can be from the same or different channels.

In channel setting, you can select a scanning list for the channel. If

the channel is chosen by using the channel selection key, the

chosen scanning list for the channel can be started by the

programmable key set to

scanning

or Manu operation.

Activate the scanning function by pressing the key set as the

Scan

function or Manu operation to scan the specified

scanning list.

When scanning, the radio will search signals of each channel till

signals are found, if the time delay between the disappearance of

signals and the resumption of scanning is set, if any signal is

received during the time delay, the radio will still stay in this channel.

Note: The current channel must be provided with a scanning list or it

cannot be activated. Scanning is available only when there're at

least 2 channels programmed in the scanning list and the scanning

is valid.

Revert channel (the transmitting channel when scanning) during

the scanning set by the dealer has the following options:

In the Scan mode, the radio can be set as to return to a specified

channel when pressing the [PTT] key.

With this function, the radio can be customized so as to meet the

requirements of the user when using the scanning function.

Revert channel has the following types:

Fixed channel

Selected channel

SCurrent Channel

Priority

1+ Current Channel

Priority 2 + Current Channel

Priority

and

Priority channel 2

. In all cases, the user can manually

select one channel for transmitting. (This will resume the revert

channel to the selected channel)

Fixed channel:

The channel specified for programming.

Selected channel: The channel selected by the scanning selector
