Scan Delete
To temporarily delete a channel from the scan list, simply input the serial command for scan
deletion to the radio while scanning and stopped on the channel to be deleted. This will
temporarily remove that channel from the scan list until the scan is closed or the radio’s power is
reset.
CTCSS / DCS Scanning
To help to block out unwanted calls to your radio, the SD-160 series can be programmed by
your dealer to scan for tones.
Busy Channel Lockout
This feature, when enabled, disables the transmitter when the user would attempt to transmit
during the receiving channel is busy. It will be dealer-programmable on/off and applicable to all
channels.
Marked Idle
When used in conjunction with Busy Channel, lockouted transmitter is allowed to operate as
long as valid RX tone is received. Dealers program this feature as ON or OFF. This feature will
be dealer-programmable on/off and applicable to all channels.
TX Time-out
This feature, when enabled, limits the amount of time that the user can continuously transmit.
This time can be set in increments by 10 seconds from 10 seconds to 990 seconds. If the user
attempts to transmit longer than the TX Time-out period, five seconds prior to expiration, the
radio will release Time-out alert signal through pin 9 of the DB-15 connector and will cease
transmission.
Power Save
The function of Power Save is used when an external battery is used as the power source.
When Power Save is enabled, the receiver ON and OFF time can be programmed and allows
the operator to set the length of time the receiver gets asleep.
Tx Delay
The TX will remain active for 150 ms at the end of TX when using CTCSS tones. This eliminates
squelch tail. Dealer programs this feature as ON or OFF.
