Privacy Code (CTCSS/DCS) Scan and Decode

Privacy Code Scan is used to determine which Privacy Code is in use 

on the current channel.
To  activate  the  privacy  code  scan  press  the  MODE  button  until  the 

privacy code number flashes, then press the SCAN button briefly. The 

Scan icon will blink when the privacy code scan is active.
The radio will scan through the 38 CTCSS and 104 DCS codes. If your 

radio detects a valid signal the scan will pause for 5 seconds.
If you press the PTT button when your radio detects a signal, the radio 

will transmit on the same privacy code and the privacy code will be 

automatically selected.
If  you  press  the  PTT  button  during  scanning,  the  radio  will  return  to 

your original privacy code. Scanning will resume when the PTT button 

is released.
To stop scanning, press the SCAN button again. 
To increase battery life use the scan modes sparingly.

Battery Level

The Battery icon indicates what the current battery level is and when 

the battery needs recharging. If necessary, refer to the instructions to 

recharge the battery.

Scan Memory

To  memorized  and  erase  the  displayed  channel  in  the  scan  memory 

list, press and hold this button. For user convenience, all the  channels 

are memorized upon shipment from the factory.

Keypad Lock

To toggle the key lock, press and hold the KEYPAD LOCK button. The key 

lock icon appears when the lock is activated. All the buttons and keys are 

locked and diactivated except for the PTT, power on/off  and Volume.

If you press the PTT button when your radio detects a signal, the radio 

will  transmit  on  the  same  channel.  Scanning  will  resume  after 

approximately  15  seconds.  Press  the  UP  or  DOWN  button  to  resume 

scanning immediately.
If  you  press  the  PTT  button  during  scanning,  the  radio  will  return  to 

your  original  channel.  Scanning  will  resume  after  approximately  15 

seconds.
