|
Channel Annunciation
|
The feature enables radio to report
the current channel number when power on or switching channel, offering you
notable convenience.
|
|
|
|
Power on Self-Test
|
The radio itself checks radio status automatically
when power on, and emits alert if an error occurs (e.g. CPU error or EEPROM
error), allows the user to early detect unit faults.
|
|
|
|
Long battery life
|
The standard 2200mAh Li-on battery,
allows more than 10 hours operation.
|
|
|
|
CTCSS/CDCSS
|
It is one type
of circuit that is used to reduce the annoyance of listening to
other users on a shared two-way radio communications channel. It is
sometimes referred to as tone squelch. It does this by adding a low
frequency audio tone to the voice.
|
|
|
|
Switchable Power (High/ Low)
|
The user can choose the transmitting
power mode according to his specific communication needs. (H: 5W
M: 2.5W L: 1W)
|
|
|
|
Low Battery Alert
|
Sets a warning for a low battery level,
before the situation becomes critical. Values are set to On to set the low
warning and Off to ignore it. The radio blinks repeatedly.
|
|
|
|
Busy Channel Lockout (BCL)
|
This feature will not allow the user
to transmit as long as the radio is receiving another signal.
|
|
|
|
Time-out Timer (TOT)
|
It is used to set the continuous
emission maximum time of Walkie talkies. When it is overtime, the radio will
stop transmitting and prohibit re-transmitting in the period of time.
|
|
|
|
Channel Scan
|
The channel scan feature enables the
radio to continuously scan each channel for activity. When activity is
detected on a channel the scan process will stop and you will hear the
transmission.
|
|
|
|
PC Programmable
|
Sanchar PC configurable radios can be
connected to a computer and configured. These applications usually provide a
user friendly way to adjust radio settings, or change user selectable
frequencies.
|
|
|
|
Wired Clone
|
Sanchar radios are capable to have
their configuration easily loaded from a different radio. This makes setup a
breeze when your business has quite a few radios. Cloning through the
programming software helps when you have purchased lots of radios, when you
are adding new radios, or when you make changes to your configuration.
|
|
|
|
VOX
|
Sanchar radios support the Voice
Activated Transmit (VOX) feature that allows you to use your two way radio
"hands-free". The radio will automatically begin transmitting when
you speak into the hands free.
|
|
|
|
TX Inhibit
|
The Transmit Inhibit Mode is a
mode in which the radio sends no radio transmission
|
|
|
|
Channel Spacing
|
To get a minimum frequency gap in
between two channels
|
|
|
|
Battery Save
|
Save battery at time of no use
which enhance battery life
|
|
|
|
Built-in Scrambler
|
The voice scrambling feature
provides enhanced security by garbling your transmissions, allowing you to
have conversations that are more private and secure.
|
|
|
|
Embedded Message
|
The radio’s memory can store
messages including service and programming records, for remarkable ease of
maintenance and service.
|
|
|
|
Stun/Kill & Revive
|
Provides enhanced security to
prevent unauthorized use of lost or rental units, by remote inhibition of
either transmit or transmit/receive. A stunned radio will return to
operational use after receiving the revive code.
|
|
|
|
Squelch Tail Elimination
|
During transmission, the random static
sound is actually the radio trying to decipher the ambient background
noise into meaningful audio. The squelch tail occurs when
the transmission has just ended and the radio circuitry doesn't respond quite
fast enough. Squelch Tail Elimination on Sanchar radios prevents this issue.
|
|
|
|
Compandor
|
A sophisticated digital voice
compression technology that reduces the static hiss between words. This
technology extends the effective range of the radio and delivers noticeably
clearer transmission quality.
|
|
|
|
Talk Around/ Reverse
|
The talk around function sets transmit
and receive frequencies to the same frequency for communicating
transceiver-to-transceiver.
|
|
|
|
Squelch OFF
|
Squelch is a specialized type of noise
gate designed to suppress weak signals. Squelch is used in two-way radios and
VHF/UHF radio scanners to eliminate the sound of noise when the radio is not
receiving a desired transmitter.
|
|
|
|
Scan Skip
|
The Skip Scan leverages
SEEK_NEXT_USING_HINT. It stores information about what set of keys/ranges of
keys are being searched for in each column
|
|
|
|
SEL Call
|
Sel-call (selective calling) is a
type of squelch protocol used in radio communications systems, in which transmissions
include a brief burst of sequential audio tones. Receivers that are set to
respond to the transmitted tone sequence will open their squelch, while
others will remain muted
|
|
|
|
PTT ID
|
PTT ID, or Push-To-Talk ID, is a generic
term for an automatic number identification (ANI)-like system used in two-way
radio systems.
|
|
|
|
Whisper
|
WSPR (pronounced
"whisper") stands for "Weak Signal Propagation Reporter".
It is a protocol, implemented in a computer program, used for weak-signal
radio communication between amateur radio operators.
|
|
|
|
DTMF Signalizing
|
Dual-tone multi-frequency
signaling (DTMF) is a telecommunication signaling system using the voice-frequency
band over telephone lines between telephone equipment and other
communications devices and switching centers.
|
|
|
|
DTMF keypad
|
The radio has a DTMF keypad which
is used to dial telephone numbers or to issue commands to switching
systems. Dual Tone Multiple Frequency signaling is the internationally standardized
way which converts decimal digits into sounds that share enough essential
characteristics with voice to easily traverse circuits designed for voice.
|
|
|
|
Backlit Display
|
Sanchar STC-804+ radios have a
digital LCD display that displays useful information, such as your current
channel. This feature allows you to turn on a lighted display, to make
information easier to read in darker environments.
|
|
|
|
Emergency Alarm key
|
The key on the radio is
programmable to start the alarm and start transmitting if pressed for over 1
second. Restarting the power supply or pressing the alarm key again exits the
emergency alarm function.
|
|
|
|
Battery Strength bar
|
Shows battery health condition
|
|
|
|
Battery Power Indicator
|
Upon press the programmable
function key, the radio sounds"1", "2" or "3” to
indicate the current battery level of low, satisfactory, or high
respectively.
