ADVANCED OPERATION (AMATEUR RADIO BAND)
rRotate the DIAL selector knob to select the ARTS mode (RX, TX, or TRX).
RX: Use this mode if you only want your radio to listen, and not poll the other station (in which case their radio should be set to the “TX” mode). Here, your radio will beep and display “In Ser- vice” or “Out Service” to indicate the state of connection.
TX: Likewise, this puts your radio into a transmit- only “beacon” mode where you won’t hear the polling beeps (but you can still hear when the other station talks). When activated, you have no display of whether the other station is in range, or not (“In Service” and “Out Service” do not appear).
TRX: Activates the ARTS feature with both operating modes.
Off: Disables the ARTS feature.
rPress the 
key to save the new setting, then press the PTT key repetitively until the radio exits from
Menu (“Set”) mode and ARTS operation has com- menced.
rEvery 25 seconds, your radio will transmit a “poll- ing” call to the other station. When that station re- sponds with its own ARTS polling signal, the display
will change to “In Service” to confirm that the other station’s polling code was received in response to yours.
rTo exit the ARTS operation, recall the Menu Item “4. Transmit” then Sub Menu “4. ARTS,” and set it to “Off.”
ARTS Polling Time Options
The ARTS feature may be programmed to poll every 25 seconds (default value) or 15 seconds. The default value provides maximum battery conservation, because the polling signal is sent out less frequently. To change the polling interval:
rPress the 
key, then press the 
key to activate the Menu (“SET”) mode.
rRotate the DIAL selector knob to select Menu Item
“4. Transmit,” then press the 
key.
rRotate the DIAL selector knob to select Sub Menu
Item “5. ARTS Itvl,” then press the 
key.
rPress the 
key again to enable adjustment of this Menu Item.
rRotate the DIAL selector knob to select the desired polling interval (15 or 25 seconds).
rPress the 
key to save the new setting, then press the PTT key repetitively until the radio exits to nor- mal operation.
