priority channels have been assigned, operation reverts
to the Scan Start Channel.
   

Last Busy

Lifting the microphone causes operation to revert to the
group and channel where activity was last detected. If no
activity was detected since turning on the radio, operation
reverts to the Scan Start Channel.
   

Voting scan

  The radio can be programmed for Voting Scan, whereby
the radio will lock onto the strongest signal in a pre-
programmed set of channels. The radio is used as
normal, with the exception that transmission is not
allowed when the unit is out of range of the nearest
repeater. Consult your Yaesu dealer for more information
regarding this function.
   
   

Programmable Function Button

   

Low Power

  With this feature enable, a button toggles between high
and low transmitter power, as programmed by the dealer.
   

MONI

  This function is monitoring for the current channel.
   

SCN

  This function is start and stop the scanning.
   

HA

  Horn Alert function On and Off.
   

Call/Reset

 When this feature is programmed and a selective call
has been received, momentarily press the button to reset
the flashing indicator and mute the receiver, otherwise
press the button to sent your radio’s identification code
(ANI) to the dispatcher.
   

Talk Around

  The feature causes a button to select simplex operation
on semi-duplex channels: the transmit frequency
becomes the same as the receive frequency (regardless
of any programmed offset for the channel).

Note: This feature has no effect on simplex channels.
After pressing the button, ”TA” is displayed on LCD.

   

Encryption

  When the Voice Scrambler feature is enabled, pressing
a button toggles the Scrambler on and off.
   

Alarm Function

  When the “alarm” function is enabled, pressing a button
causes the radio to revert to a specially designated
channel, and causes the special “alarm” identifier code to
be transmitted automatically.

Note: This feature is only available as a “Secondary”
accessory to prevent accidental activation.

   
   

Fuse Replacement

 If a fuse is blown, before replacing, see if you can
determine if it was caused by something outside of the
radio (perhaps a short circuit due to a worn cable or
pigtail near the radio). Contact your Ysesu dealer at once
if you do not find the cause. Replace fuses only with the
same type installed.
   
   
   
This is device complies with Part 15 of the FCC rules.
