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.

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.

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: 10W  M: 5W   L: 2.5W)

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 handsfree.

Emergency Alarm:

The emergency button allows for a transmission of a signal indicating an emergency situation.

Led Torch:

Useful in emergency to get lightening in dark areas.

Channel Spacing:

To get a minimum frequency gap in between two channels

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.

Battery Save:

Save battery at time of no use which enhance battery life

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
