BACKGROUND OPERATIONS

Wide / Narrow Band Setup

On the basis of national conditions, users can set channel spacing
as 25K (wide band) or 12.5K (narrow band) to communicate on the
transceiver by programming software.
This transceiver can realize 25K (wide band), and 12.5K (narrow
band) etc as communication way.
NOTE:
"N" on LCD indicates narrow band. Otherwise it is wide band.

Busy Channel Lockout

When BCL function is enabled, you can not transmit in busy
channel. BCL prevents you from interfering with other parties who is
using the same frequency point that you select. Under this condition,
if you press the [PTT] to transmit, the transceiver will emit beep
prompt and return to receiving mode.
Users can set Busy Channel Lockout mode by programming
software.
1. Repeater: Repeat lockout, transmitting is inhibited when current
channel receives a matched carrier with different CTCSS/DCS.
2. Carrier wave: Carrier busy lockout, transmitting is inhibited when
current channel receives a matched carrier wave
3. Close: BCL disabled, you can do transmission under whatever
receiving state.

Accession to Scan List

Via programming software, users can choose whether to add
current channel into scan list. If current channel is not in the scan
list, the transceiver will skip this channel when scanning.

Time-out Timer

The purpose of the Time-out Timer is to prevent any caller from
